Wrapper.Classpath and NFS issue

Using Jserv1.1.2
It seems that there are Issues When you try
to create
wrapper.classpath that points to a mapped Network drive
using NFS protocol.
It result in a Internal Server Error
Did someone encounter same issues??
Thanks to answer.

Well, the JAR I'm trying to add is here.
The instructions specifically say to put it in the ext folder.
The JAR should contain an Options application which I should be able to open by only typing "java Options".Based on what? Do the docs say specifically that? Is the Options class in a package?
Again, you're not providing much in the way of detail, so all I can say is that there's something wrong with your assumptions.

Deadlocking issue with sshfs and nfs

Okay, I've used both sshfs and nfs for remotely accessing the home partition on my fileserver, but I have been having a problem where the networking on the server suddenly cuts out. Any processes that are accessing the folder I mounted nfs/sshfs with become deadlocked. Any processes that try access my home directory, where the remote folder sits, are also deadlocked. I cannot get into the machine with ssh. I have to manually reboot it in order to get any networking at all.
I have to also force-kill any known processes that are accessing the remote folder, and if I don't know what they are, I have to forcibly unmount it. This issue has been occuring with this specific fileserver since I got it. It is running Arch Linux i686, but has had the same problem with the server editions of both Fedora and Ubuntu.
I don't know where to begin with fixing this problem, nor do I know how to diagnose it.

Consider "soft" mount option for NFS.

Custom classpath and custom jar entry in R12

Hi all,
I have created the custom classpath and custom jar file for isrore process. I had put custom jar and custom class entry in orien_application.xml file. But it was working on R12 at doveloper mode. It will creates the classes for custom jsp file using custom import class or custom jar. But once i revert back the devloper mode means it won't work.
Could you please help..

Oracle apps R12 - Compiling JSP with custom classpath
We all know that to compile JSP manually on the Oracle Application R12 instance, we need to run the file $FND_TOP/patch/115/bin/ojspCompile.pl.
Its help is as follows:
syntax: ./ojspCompile.pl COMMAND {ARGS}
COMMAND --compile               update dependency, compile delta
--create                rebuild entire dependency file
-delta.out update dependency, list delta to file
-dep.out update dependency, output heirarchy to file
ARGS -s matching condition for JSPs filenames
-p number of parallel compilations
-log to override logfile from ojspCompile.conf
You are
recommended to set the log file location
outside of any network file system shared (NFS) area/drive.
-conf to override ojspCompile.conf
--retry         retry previously failed compilation attempts
--flush         forces recompilation of all parent JSPs
--quiet         do not provide an actively running progress meter
--fast          instantly fail jsps that are possibly invalid
example1: ojspCompile.pl compile -s 'jtf%' -p 20 retry
example2: ojspCompile.pl compile -s 'jtflogin.jsp,jtfavald.jsp' flush
example3: ojspCompile.pl compile fast --quiet
If your JSP uses custom classes, then compiling jsp manually can fail if proper classpath is not set. Yes, even though if you have setup the classpath correctly in orion-application.xml, it will fail because this jsp compile utility does not read orion-application.xml classpath.
So, the problem is to identify where to set the classpath so that above utility can pick it up. After several search and looking into code, I found following:
By default, the jsp compiler script uses following configuration file
$INST_TOP/appl/admin/ojspCompile.conf
This conf file has a classpath field in it which is usually pointed to file
$INST_TOP/appl/admin/ojspCompile.properties
This property file lists the classpath used for JSP compilation.
So if your classes are not listed in this file, your jsps will not compile by ojspCompile.
Ofcourse, you can always set the "main_mode" to "recompile" in orion-web.xml, but that for production you do not want to change it and compile the JSP on file deployment.

Very interesting and quizzical issue in JNI COding.

HI All,
i've been facing a really frustrating, interesting and mindwrenching issue in my native code. Here is a background.
1. I was given a thirdparty ACtiveX OCX file that needed to be called through JAva.
2. I wrote a C++ JNI wrapper to call the methods of the activex object.
3. I first initialize the object, set the relevant parameters (sent from java) and then call the method I need.
4. For every record, I need to perform step 3. NOw, I am ryuning batch loads. THE code works fine for 9500 records. BUt, once the record count reaches 9885, I get a pop-up error from the activeX OCX control. I've not coded that pop-up. It comes out of the blue.
I initially thought that it could be a memory issue, but even after doubling my VM Memory allocation, I get the error. Its not a data issue, because the reocrd that causes the issue, if I run the code just for that single record, it works fine.
Below is the implemetnation of the C++ code. LEt me know if I'm doign somethign wrong or if someone has seen something like this happen before. WHAt is baffling is that it works smoothly for less records. When the pop up appears, no exception is caught on the native side also.!!!
Does java set aside some memory specfic for native libs and that is exhausted after 9885?
I'm running on windows, so is it possible to trace the internal malloc and release within the dLL?
ANy thoughts and ideas will help. I've been struggling for about three days now. ALso, do you know of a good C++ forum that i could post this question?

Well you have now demonstrated conclusively that it has nothing to do with JNI.
It is either a bug with that component and/or you are using it incorrectly. Solutions to either of those would come from the source of that component, which would be somewhere besides here.
If it was a bug then you might find a way around it by doing one of the following
1. Try variations of use (options, parameters, whatever.)
2. Determine if you can solve your problem by only processing 5000 entries at a time (where 5000 chosen just to be significantly lower than the limit you have already found.) If that works then you can solve the problem by using a restartable executable that wraps the component.

[SOLVED] Netbooting with PXE, TFTP and NFS / Numerous errors

Greetings all, hope you can help me out.
Been given a task by my company of making a network bootable ICA client (with X and Firefox, with the Citrix ICA client installed) as small as possible to minimize network traffic (as 440 workstations would be downloading the end-product simultaneously, so it'd beat ten bells of proverbial out of the core and edge switches for a little while). I discovered two options. One being to integrate everything in side a cloop image directly inside the INITRD. I have stacks of working INITRDs with their matched kernels yet being my first dabble in to extracting the INITRD, my faffing with CPIO has resulted in me nuking my base layout (Thank god for snapshotting in VMware Workstation!) 4 times, and either getting "Premature end of file" or a copius amount of lines stating "cpio: Malformed Number: <strange characters>" finally ending with "Premature end of file". As a result I went in search of another option, which would be booting off an NFS share. I followed the guide:
http://wiki.archlinux.org/index.php/Dis … t_NFS_root
...in order to set up a network booted install of Arch and hit a few snags along the way, probably a result of using multiple operating systems for the TFTP and NFS server as opposed to using what the guide recommends, but I'm not sure as these seem solvable, although I don't know how right now.
The set up:
DHCP is provided by a Microsoft Windows Server 2003 VM (AD Integrated) on 172.16.10.17 on a box called "Rex".
TFTP is provided by another Windows Server 2003 VM by "TFTPd32" which is a free download. This is located on 172.16.10.158 on a box called "Terra".
The NFS store is provided by OpenFiler 2.3 which is a specialized version of rPath Linux designed specifically for turning boxes in to dedicated NAS stores. This is located on 172.16.10.6, and is called "frcnet-nas-1".
The problem:
DHCP is correctly configured with a Boot Host Name (Which is 172.16.10.158) and a boot file name of "pxelinux.0". This is confirmed as working.
Client gets the kernel and INITRD from TFTP and boots up fine until it hits "Waiting for devices to settle..." by which point it echos out "Root device /dev/nfs doesn't exist, attempting to create it...", which it seems to do so fine. It then passes control over to kinit and echos "INIT: version 2.86 booting" and the archlinux header, and immediately after that it prints:

...and, nothing after that, it just stops. Kernel doesn't panic, and hitting ctrl+alt+delete does what you'd expect, a clean shutdown minus a few errors about filesystems not being mounted. It seems /proc isn't getting mounted because init apparently doesn't have the appropriate permissions, and /proc not being mounted causes a whole string of other issues. Thing is, proc gets created at boot time as it contains kernel specific information about the system and the kernel's capabilities, right? Why can't it create it? How come init doesn't have the same privileges as root as it usually would, and how would I go about fixing it?
I admit, while I'm fairly competent in Linux, this one has me stumped. Anyone have any ideas?

The idea behind the Windows DHCP and TFTP is that we'd be using an existing server and a NetApp box with NFS license to serve everything off. I would have loved to make a new server which is completely Linux, but my boss, nor the other technician have ever used Linux so if I left for any reason, they'd be stuck if ever they ran in to trouble, which is why I've struggled to get Linux to penetrate our all Windows infrastructure.
During my hunting around on Google I found a lot of information on making my own initrd, and a lot of it using all manner of switches. I can make them fine, but I figure that I would need to look at extracting the current working one first, adding X, Firefox and the ICA client to it, then compressing it again. Cloop came about when I was looking at DSL's internals. The smaller the initrd, the better, so utilizing this could possibly be a plus too.
The reason I'm doing this with Archlinux is that I know Arch's internals quite well (and pacman is just wonderous, which is more than I can say for yum), so if I run in to a small problem I'm more likely to fix it without consulting Google. Fair enough though, the NFS booting method is giving me issues I never thought were possible. Ahh, sods law strikes again.
Addendum: I've noticed something which struck me as odd. Files in the NFS share are somehow owned by 96:scanner instead of root:root. Upon attempting changing, it's telling me "Operation Not Permitted". Further prodding has led me to believe it's an Openfiler thing where GID/UID 96 on the OpenFiler box is "ofgroup"/"ofguest". Chowning / to root:root puts NFS boot right ahead and gives me a prompt, however I cannot log in as root. I've also discovered that chrooting in to the base from my Arch workstation and creating a directory makes the directory owned by ofgroup:ofguest again, so it's an Openfiler thing after all this time. Prodding further.
Addendum two: For anyone using Openfiler out there, when you allow guest access to the NFS share, be sure to set the Anonymous GID and Anonymous UID to 0. By default it's 96 and as a result when trying to boot you get the errors I experienced. This is insecure and you should use some sort of network/host/ip range restriction. Because the root filesystem has 96:96 as the owner of everything after you install the base layout using pacman (and any changes you make afterward) init and root no longer have the appropriate permissions, user 96:96 (which is "scanner" in Archlinux) has the permissions instead and init, in order to complete boot would need to be "scanner" in order to boot completely.
Solution is to set Anon GID and Anon UID to 0, chown the entire diskless root filesystem to root, then use a linux desktop to mount the diskless root filesystem, mount /proc, /sys and mount bind /dev, then chroot in to the diskless root filesystem. At this point to clear up any problems with bad passwords, use passwd to change your password. Exit the chroot environment then unmount the diskless proc, sys and dev. Boot up via the network and use your chosen password to log in as root. At this point, start clearing up permissions from the en masse filesystem chown and you should then have a usable diskless root.
I'll experiment further and clear up some of the remaining permission errors that occured during boot and report on my progress in fixing it. Didn't like the idea of chowning the entire share as root. :S

PTG102 for linux: panama_core.zip in wrapper.classpath

Hi,
I set some wrapper.classpaths in the jserv.properties as installation guide described. But after restarting apache, the ApacheJserv doesn't work anymore. I try to comment/uncomment each wrapper.classpath line and I find the panama_core.zip in <PTG_HOME>/panama/lib is the reason.
I use the following command to test panama_core.zip to see if it was corrupted. But it seems to be no problem.
jar tvf panama_core.zip
So, what's the problem with this file?
I use JDK 1.2.2(blackdawn)
I set the following line in my httpd.conf, so I can see the status from http://myip/status/jserv/
<Location /status/jserv/>
SetHandler jserv-status
Order deny,allow

if you're using ias 8i/9i or rdbms 817
consider the following :
Problem Description
You are trying to call a simple Java Server Page using iAS on Tru64 Unix.
The call fails with java.lang.NoClassDefFoundError: sun/tools/javac/Main
Solution Description
Go to the Jserv configuration directory ($ORACLE_HOME/Apache/Jserv/etc)
and edit the jserv.properties file.
Uncomment the following line :
#wrapper.classpath=/jdk12_home/lib/tools.jar
Replace jdk12_home with the location of your JDK, typically
/usr/opt/java122
If you are using JDK 1.1.X, replace tools.jar with classes.zip
(e.g. /usr/opt/java118/lib/classes.zip)
Explanation
Java Server Pages need to have access to the java compiler, in order
to generate the servlet from the JSP.
The JDK is not automatically included in Jserv's classpath

After Effects CS4 and NFS Network Drop-Outs

Hi all,
We're experiencing a high number of NFS drop-outs ever since we've upgraded our department to AE CS4. I'm not saying CS4 is the culprit, I'm just saying this is when we started noticing the issue.
13 Apple MacPro 8-core systems. 12 Leopard, 1 Snow Leopard.
Projects are located on an Apple XServe 2.26 Quad-Core Xeon with 12GB RAM running 10.5.8 Server
Projects are shared up via NFS protocol via gigabit network.
Basically throughout the day, a random number of peole will lose connection to the NFS share, to which it returns on its own in a few moments. Though it's not everyone each time, all users encounter the issue at least once-a-day, usually more. (We have to different servers with NFS shares, one does not drop, the other does) The server that drops the share is the newer XServe Leopard and is the primary server where all the footage and projects are located. The 2nd server is just secondary library media and stock footage...
Essentially, I'm curious if anyone else is having NFS issues since the update to CS4. I'm just trying to weed out all elements. It's hard to say if it's the server itself, as the logs only note a drop once-in-a-while... We also use Rush Rendering for our Maya renders, which we have just upgraded to the latest version and we get drops even when no one is using Rush or Maya...
Very strange but extremely frustrating issue. It's not fun when someone is working on a project and loses it because the share drops out.
Any input greatly appreciated. Let me know if you need more info.
Thanks!

Session timeouts.... I really do think it's the server. AE doesn't care for specific network stuff, it's all just volumes/ drives to the program. To avoid these issues, you would have to shorten the refresh cycles on your server availability broadcasts or the "keep alive" cycles on the connection/ session settings themselves. I'd know how to do it on Win Server, but I have no clue with regards to XServe configuration. Still, certainly some simple console commands and a restart of the server software should be able to take care of the matter.

WebLogic 11g EAR EJB Classpath and class loaders

All,
I have been having issues migrating Spring based EJB applications from OC4J to WebLogic 11g (10.3.1). I have been in communication with Oracle who has suggested a work around however I am keen to see if anyone else can suggest a solution.
The application is dependant on stateless session EJB beans that communicate with a Spring managed service tier to perform the business logic and database access. PitchFork is used to inject the Spring managers into the EJB’s using the spring-ejb-jar.xml configuration file. Note originally I was using the SpringBeanAutowiringInterceptor however I could not get this to work. See WebLogic 11g and Spring beens injected into EJB for details.
When the application is deployed packaging all the dependant jars within the APP-INF\lib folder I get a verity of errors from the following InvalidClassException, NoSuchMethodError, AbstractMethodError and IllegalArgumentException. I am using Spring 2.5.3 to match the supported WebLogic version. Note within the EAR application.xml the library-directory is set to APP-INF/lib. The issue appears to be Spring, PitchFork, commons-logging and aspectj libraries are being loaded form WebLogic and do not have visibility on jars within the application or have been modified when bundled for WebLogic. An example of this is the PitchFork jar within WebLogic has been changed excluding the spi package resulting in java.lang.ClassNotFoundException: org.springframework.jee.spi.PitchforkUtilsImpl errors.
Moving the jars to the domain library path does not resolve any of the issues. I have been unable to successfully deploy the application picking up the application jars using the prefer-application-packages configuration.
Oracle has advised me to deploy the libraries into the WebLogic system classpath by modifying the startWebLogic command to load the libraries into the classpath. I am concerned that modifying the system classpath will result in an unstable WebLogic server as I will be replacing modified jar files packages with WebLogic (such as PitchFork). This will also limit the applications that can be deployed within the server as each application must use the same libraries and versions (as the application ibraries are leing ignored).
Has anyone else hit this issue and corrected it? Can anyone think of an alternative solution?
Regards
Neil

Hi,
I am in the process of updating the tracking bug# 331569 with copies of the eclipse EAR/WAR projects and the EAR for these scenarios. Here are some details on how I got past the 2nd CCE on the org.eclipse.persistence.jpa.PersistenceProvider class (not the javax one)
https://bugs.eclipse.org/bugs/show_bug.cgi?id=331569
Essentially an SE persistence unit running both JPA 2.0 api and the 2.0 XSD schema work fine. I will next retest the EE case with variations of the 3 types of injection on the SSB or Servlet.
Update: There are 3 (possibly 4) issues here (all of these may become obsolete when the next WLS version ships)Initially I got the same 2.0 schema error and the ClassCastException on org.eclipse.persistence.jpa.PersistenceProvider
It turns out that my import of the 2 eclipse projects from my bug # 296271 for WebLogic 10.3.2.0 lost their facets(specifically the dynamic web facet) because I associated them with a different WebLogic 10.3.3.0. - this caused the CCE I was experiencing like Sri.
Anyways, after creating an EAR/Web project combination from scratch in eclipse associated with the 10.3.3.0 instance - I predeployed/deployed/ran fine - even with the 2.0 schema - in SE bootstrap mode (no EE yet).
Reproduction Procedure:
redoing project from scratch as I noticed that the war was not at the root of the ear - it was a jar in the app-inf/lib dir - my imported eclipse project was not referenced correctly as a web module facet- create empty EAR and WAR project with references
- download and open my EAR and WAR project code from bug # 296271
https://bugs.eclipse.org/bugs/show_bug.cgi?id=296271
- do essentially all the steps in the page below (I paraphrase for re-verification)
http://wiki.eclipse.org/EclipseLink/Development/JPA_2.0/weblogic#DI_1.1:_Alternative_3:_Application_Level_Shared_Library_-InUse
- copy applicationService, entity and FrontController servlet code into new projects
- create persistence.xml and MANIFEST.MF manifest in src\META-INF
- update manifest
Class-Path: APP-INF/lib/eclipselink.jar
APP-INF/lib/javax.persistence_2.0.0.v200911041116.jar
- copy both javax.persistence 2.0 and eclipselink 2.x jars to APP-INF/lib
- change ordering of WebLogic library modules classpath reference (javax.persistence 1.0) to ear reference (2.0 version)
- update web.xml with servlet tags
- update weblogic.xml with new context root
- make the persistence unit name the same in persistence.xml and ApplicationManagedService
- update weblogic-application.xml with prefer-application-packages overrides
<wls:prefer-application-packages>
<wls:package-name>javax.persistence.*</wls:package-name>
<wls:package-name>org.eclipse.persistence.*</wls:package-name>
</wls:prefer-application-packages>
- enable server redirect logging

<property name="eclipselink.logging.logger" value="DefaultLogger"/>
- start WebLogic 10.3.3.0
- deploy (run on) server from eclipse or export ear to auto deploy directory
1) JPA 2.0 XSD usage on 10.3.3.0

LDAP and NFS mounts/setup OSX Lion iMac with Mac Mini Lion Server

Hello all,
I have a local account on my iMac (Lion), and I also have a Mac Mini (Lion Server) and I want to use LDAP and NFS to mount the /Users directory, but am having trouble.
We have a comination of Linux (Ubuntu), Windows 7 and Macs on this network using LDAP and NFS, except the windows computers.
We have created users in workgroup management on the server, and we have it working on a few Macs already, but I wasnt there to see that process.
Is there a way to keep my local account separate, and still have NFS access to /Users on the server and LDAP for authentification?
Thanks,
-Matt

It would make a great server. Bonus over Apple TV for example is that you have access via both wired ethernet and wireless. Plus if you load tools from XBMC, Firecore and others you have a significant media server. Cost is right too.
Many people are doing this - google mac mini media server or other for more info.
Total downside to any windows based system - dealing with constant anti-virus, major security hassels, lack of true media integration and PITA to update, etc.
You should be aware that Lion Server is not ready for prime time - it stil has significant issues if you are migrating from SNL 10.6.8. If you buy an apple fresh Lion Server mac mini you should have no problems.
You'll probably be pleased.

Failed Hardware Scan and other issues E440

Hi all,
This is probably more rant than anything, but I wanted to give a heads up to others too.
I have a ThinkPad E440 that is a year old. From the very first time I turned it on, there have been issues. The first hardware scan (via Lenovo Solution Center - LSC) showed a warning for the Intel Dual Band Wireless-AC 7260 Local Connection Test. There were also tons of System Events that always show up in the "Configuration History" part of the LSC. You can look at the calendar and tell exactly which days I used the computer because there will be System Events generated each day. Things like app crashes and failed drivers.
In July 2014, I got the first warning for the 16 GB SSD - the SMART Short Self-Test. By February this year it showed as failed for each hardware scan (these were initially set up to run monthly).
Also the whole time I've had it the touch screen would just stop working at some point and I would have to reboot to get it working again.
I finally called Lenovo on March 30th, before my warranty expired. When I called that time, I didn't realize the hard drive failure was the SSD. So they sent me a new 500 GB drive. I also added the other things into the case when I talked to them. For the wireless issue they suggested making sure the driver was up to date. I did this and let them know when I called back that it was up to date and still having the warning. So I called them to tell them to tell them about the wireless and also that I realized it was the SSD having the failure, not the main drive. The first case had already been closed even though none of the other items were addressed.
So they opened another case (this is #2). They said to mail them the laptop since the wireless issue would probably be on the board and it wasn't something I could fix myself. They sent a box with a prepaid overnight shipping label. I was very sick for a few days so I sent it back to them on April 10th (a Friday). Via UPS I saw it was delivered on Saturday. Work was performed on it Monday, April 13th and sent back to me that very day. I received it on April 14th. This part of the service has been excellent - very fast response.
Being in IT, I included a letter with the laptop that outlined the issues that should have been in the case. I also printed the hardware scans and what the system events looked like.
When I got the laptop back, the sheet inside said they had replaced the Speaker because of Distorted Sound. This was not even on the list even though I had noticed it. I didn't even power up the laptop before calling them again - yes, I was furious! Plus our power was out...
So this was noon on the 14th. They opened case #3 and sent me ANOTHER BOX so I could send it back.
After our power came back on the 15th, I powered up my laptop. I opened the browser (I have it set to restore the previous session) and there was a sexually explicit video on YouTube. I opened the other browser and there was a different video on YouTube. So this person was watching YouTube instead of fixing my laptop. I looked through both browser histories and there was quite a bit of activity while my laptop was at the repair center... I ran the hardware scan - still failed and a warning for the wireless. They really hadn't done anything.
I also found two pictures of the repair person in the recycle bin...
So I called back. I was LIVID! They opened another case (this is #4). And sent me ANOTHER BOX. I finally learned the other day that once a case is opened, it cannot be edited or added to at all. Instead, they close the other case and open a new one. I guess their turnaround time for closing cases is excellent! I've never seen a system like that - and I've used a lot of them.
I got a really nice, patient fellow on the line. He took all my info (again). I emailed him the pictures, screen captures of the YouTube videos, the letter I had sent - everything. He entered as much into the new case as he could - he talked to one of the supervisors to make sure he did it right. Somehow he flagged it so that the laptop would get more attention (time) at the repair facility. He also opened a separate case (an escalation ticket?) for a supervisor to call me regarding the person's conduct at the repair facility. He said they would call me that day. (It's now the 25th and I've never heard from anyone)
So, he sent me ANOTHER BOX. I've built up quite a stack of them.
Our power was out AGAIN from the 17th through the 19th (don't get me started).
I noticed a hardware scan had now gotten a failure on the main hard drive. So I called them on the 21st to add this to the case before sending the laptop back. The girl said they can't add anything to an existing case or edit it at all once it's opened. She would have to open a new case and SEND ME ANOTHER BOX. I told her to forget it because I was ready to send it in and didn't want to wait for another box. I also asked for a status on that "escalation case" where the supervisor was supposed to call me. In order to do this she, yes, wait for it, had to open ANOTHER CASE!! So they would know I wanted a status. I'm completely dumbfounded.
So I sent it back on the 21st. This time I practically wiped it. I had already removed all my files the last time, but I had left my bookmarks and browser history intact. I set up a guest logon with admin privileges. I updated my letter and printed off more stuff to include with the box. On one sheet I had only the case number, the serial number and machine type. On another sheet I had "DO NOT SEPARATE THIS PAPERWORK FROM THE LAPTOP" and the case number. I put this sheet on top (The guy on the 15th said my letter and stuff may have gotten separated from the laptop once it was delivered to the repair facility). I used a ton of staples so it would all stay together. I included in my letter the failure on the main hard drive and asked if they could look at it. I wrote about having to open a new case if I wanted to include it.
They received it on the 22nd. A nice gentleman from the repair facility called me that day asking about the password. that. was. written. on the sheet they have you fill out. I told him what happened last time and also mentioned the hard drive failure and asked if he could look into it. He said they would.
I received my laptop back yesterday morning.The sheet that came with it said they had "replaced the following parts to complete the repair of your laptop."
Part Description                                           Symptom
IMAGE                                                             Replaced due to engineering change
System board                                                 Network card error
Hard disk drive                                                Network card error
ECA-WIRELESS                                            <no symptom listed>
There was also a sheet saying they had installed a factory preload of software and I needed to install Lenovo and Windows updates.
When I booted it up, the first thing I noticed, in the lower right corner was:
Windows 8.1
SecureBoot isn’t configured correctly
Build 9600
I ran a hardware scan. Well, I tried. It stopped part way through and said it finished successfully but most of the tasks showed up as cancelled. I tried to run it again - issues - rebooting ensued. It said the LSC wasn’t available and that I should try again or reboot.
Tried several times. Then got what I guess is the new BSOD - kinder, gentler:
Your PC ran into a problem and needs to restart. We're just
collecting some error info, and then we'll restart for you. (xx% complete)
If you'd like to know more, you can search online later for this error: DRIVER_CORRUPTED_EXPOOL
Even though the LSC said my Lenovo files were all up to date, I ran the Update. And first I had to download a new version of Update. Then I downloaded all of the Lenovo updates and installed them (there were quite a few). The BIOS update failed. While I was doing the Lenovo downloads, I got a light blue screen but no text (I was out of the room so I'm not sure what happened). Did CTRL-ALT-DEL and it shows only IE and Task Manager as applications that are running. Could not “Switch to” IE. Hitting window key to go to start didn't do anything. So I had to restart.
By 3pm yesterday there were 34 system events in the configuration history.
I ran the hardware scan again after I updated the Lenovo files, and you guessed it! Failure on the SSD (SMART Short Self-Test) and warning on the wireless. Nothing had changed. Except hardware scan is acting different than it did before I sent in the laptop for repairs. When it finishes, it instantly closes and just shows 100% complete. When I click on "see last results" it shows a screen called
Log Information,
Canceled 04/24/2015 n:nn pm
You have not done a hardware test on your computer
And the calendar in LSC only shows the very first hardware scan I did on Friday. Even the hardware scan screen shows the date and time of the last scan. It also shows the error code. In order to see exactly what is failing, I have to sit there and watch it very closely and snap a picture of the screen as soon as the error (or warning) shows up.
When I would try to run Windows update, it would hang up PC Settings. I couldn't even kill it using task manager because it didn't show up as a task. During this, I got a flag saying the firewall wasn't turned on. I tried to turn it on, but clicking on Turn on Windows Firewall didn't do anything. I tried to setup my Microsoft account but that just hung too.
I ended up running Windows Update FOUR TIMES to get all the updates installed. Every time I ran it, it said "Done!" and I would run it again and more would show up. The last time was this morning.
At some point, the error about SecureBoot went away.
Then, I created a bootable BIOS update disk. Following the ReadMe instructions, I went through ThinkPad Setup and verified several values. Of note:
Secure Boot was DISABLED. According to the ReadMe file, this should be ENABLED in Windows 8.1. I enabled it.
Under Startup/Boot, according to the ReadMe that came with the BIOS update, UEFI/Legacy Boot is supposed to be set at UEFI Only for Windows 8.1. Mine was set to "Both". I changed it.
In Startup, OS Optimized Defaults was DISABLED, even though it says right there (and in the BIOS update ReadMe) it should be ENABLED to meet Microsoft Windows 8 Certification Requirement.
After these updates, I flashed the new BIOS.
Then, I ran hardware scan again...
Now I have TWO failures on the SSD: Random Seek Test and SMART Short Self-Test. Great.
In the Event Viewer (that I recently discovered), it says my disk has a bad block. It just says The device, \Device\Harddisk\DR1, has a bad block. I assume this is the SSD...
There are 867 events in the event viewer - Critical, Error, and Warning...
Fifty-two of these are from October 7, 2013 - before my little laptop was a glimmer.
The rest are from when Lenovo had it and yesterday and today.
64 of them are the disk error.
341 are from DeviceSetupManager. 65 of those are from failed driver installs. 69 are for not being able to establish a connection to the windows update service. 64 are from not being able to establish a connection to the Windows Metadata and Internet Services (WMIS).
3 times it's rebooted without cleanly shutting down
60 of them are from Service Control Manager and say The TDKLIB service failed to start due to the following error: The system cannot find the file specified.
One of them says {Registry Hive Recovered} Registry hive (file): '\??\C:\Users\Default\NTUSER.DAT' was corrupted and it has been recovered. Some data might have been lost.
16 are warnings that various processors in Group 0 are being limited by system firmware.
12 say the certificate for local system with thumbprint <bunch of hex numbers> is about to expire or already expired.
108 are warnings for failure to load the driver \Driver\WUDFRd for various devices
16 are application errors
One is for the computer rebooting from a "bug check"
15 are for name resolutions timing out after none of the configured DNS servers responded.
10 are for SecureBoot being disabled.
14 for services terminating unexpectedly
15 are for WLAN Extensibility Module has stopped
61 are for applications not being able to be restarted because the application SID does not match Conductor SID
12 are for activation of CLSID timing out waiting for the service wuauserv to stop
So, I'll call them on Monday and open. a. new. case (#5?) - but really 7. And get A NEW BOX.
I'll keep you updated!

Battery, heat, and ringer issues

I recently purchased the Iphone 4s.. this is my first iphone
I did the update that Apple sent out to help the battery and it seems like it worse then before the update?? My phone has been off the charger for 45 minutes, I sent 1 text message, and had 1 phone call. The percentage is now at 87. It the last 2 minutes i have watched it go down 2%? Is this normal? Also, the phone gets REALLY hot...
If not, what do I do now??
Also, I keep missing phone calls because I don't hear the phone ring... but the ringer is all the way up..
Any help will be greatly appreciated!!

1. Connect your Z10 to the wall outlet charger for an hour and then with the Z10 powered on, and with it STILL CONNECTED, remove the battery for a minute and replace. This will normally reset the the on-device battery meter and allow the charging status and percentage to show more correctly.
2. Orange is your tech support contact and any issue which they cannot resolve, they should escalate up to BlackBerry tier two tech support, or you should ask/demand that.

New Airport Extreme and iPhone Issues

I've had the networking day from ****. I previously had a 3rd Gen Time Capsule at our restaurant, connected to a Cisco 26port gigabit POE switch and Comcast digital voice and internet. Over the past few days, employees have reported trouble accessing the the Wifi network. After several restarts and firmware upgrades (including the dreaded "firmware problem" to fine update), nothing worked. I changed channels, back to auto, back to specific channels, back to auto. Made open guest networks. Nothing worked consistently. My iPhone might connect and my friend's might not. Nor his laptop consistently. Our Axis network cameras might take a bit extra time to connect. All quite random and quite frustrating.
So I swap out an older Airport Extreme (4th gen I believe) using the same configuration as the TC (Time Capsule). It works fine, except for the last port not working as expected. No matter, I plug the mac mini into the Cisco switch and off we go. Nevertheless, I'm still told we are suffering random Wifi issues. So I buy a brand new AE (5th gen) today to replace that one. Should work like a charm I thought. Right....
Several hours later, I finally have the new AE working, but only after doing several hard resets/factory restores, the works. For some reason, the mac mini could not successfully update any of the connected AEs - whether connected directly into the same AE, or if the Mini was connected to the switch. Nothing worked. Every time I tried to update the AE, it would hang and force me to unplug and plug it back in. It would also never save setting changes. I finally resorted to a friend's macbook to be able to restore it successfully. And once that worked, the mini was able to update the AE flawlessly. Our Point of Sales (POS) machines connect fine, our cameras connect fine, wifi printer connects, and the mini connects, and everything has internet.
Except my iPhone 5. Of course. It gets a signal fine (full bars). It gets an IP address. But I can't surf the web. Or download email. Or iMessages. Anything. No internet access. I try hard restarts on my iphone. I try assigning IP addresses by MAC address. I try resetting the AE. I try renaming the WiFi name. Nothing. I can make a guest network that works (on a different IP table, btw - 172, not 192.) But other than that, no access. Grrrr.
So I have a "working" AE router where some devices successfully connect (through wifi and ethernet) and some dont' (wifi iPhone). My iPhone connects fine to my home TC. So shouldn't be anything to do with that. But I'm at a loss. I'm going to go back and restore everything and power cycle everything tonight or tomorrow night. I don't know if that will help, but it's worth a try. Lord knows it feels like I've tried everything else.
Anyone have any good ideas of where to start besides voodoo dolls and baseball bats?

I took mine back, because I was having these very same issues. We use contivity too. I was able to connect only to one of three of the servers we manage (in Europe). I couldn't connect to the servers in Asia or here in the USA.
Replaced the Airport Extreme with my trusty old d-link 624, and no issues connecting to any of the three hubs.
Otherwise, I liked the Airport Extreme, and I'll consider buying it again when and if they address this VPN issue. I work at home so its obviously a "deal breaker" for me.

I have an ipad mini 1st gen 64 gb (wifi only) and i have problem with some of my apps. These apps have lags when you play with them for a few seconds the apps are having lags are call of duty strike team, gta San Andreas and nfs most wanted.pleas help me

I'm going to guess videos buffer for a while also...
Two possibilities, one is you should close apps on the iPad, the other is your internet speed is not able to handle the demands of a high speed device.
To close apps: Double click home button, swipe up to close the apps.
To solve internet problem, contact your provider. Basic internet is not enough for video games and movies. Your router may be old and slow.

IQ826t Restart and Heating Issue

One thing I definitely do not like the HP's support especially when they will not allow us to buy a 7 Upgrade from Vista nor will they support something (even when I find their glitches and they admit after telling me it was just the OS).. On Repair work, I had to ship it out and this will be my 2-3 time to do repair on this PC in the past 3 years (and I have to wait a week for the repair to be done...)
Besides that, IQ826t, Win 7 Ultimate SP1
All Drivers are up to date with HP website (utilizing Win 7 64 bit drivers and Firmware is up to date). AVG update/scan (no issue - confirmed even rootkit).. Malwarebyte - Scan and no issue
Disk Cleanup, Disk Defragmentation done on a monthly and quarterly schedule
Biggest Issue:
I am getting a crash with Win 7 0x124 Stop Error Message (happens periodically and even after a reboot)
Never had this issue until May and the upgrade to Win 7 was done last year with SP1 update done on March (so it is not an issue with the OS as HP support personnel seems to think... I proved them the issue with Windows Update History, The Bluescreen error code on my error code reader).. This machine under warranty and I had issues with it constant (even in Vista)
They state that it is the OS.. Again, if that was the case, I would think it would happen right away like my Toshiba on SP1 upgrade... That was not the case in the matter. I have a firmware reset (default settings) and the issue persist..
The Error Code relates always HAL.dll or ntoskrnl.exe
One if hardware compatiblity and the other is an OS kernel exe file.. And this usually checking knowledge base relates to hardware failing due to 1) Compatibility (which HP website confirms is not the case) 2) OS corruption (which is not the case checking on safe mode and this happening STILL 3) Heat Issue (which I believe is the issue and was been documented on the Internet
What I am noticing is the unit is extremely HOT (vent is almost burning when it has been off and just turned on).. I wonder if the hardware pieces are literally melting to destruction since I can't just open it up (they state it will void my warranty)
The Symptoms before the Crash (happens any time.. Even right after a power up)
If you are playing audio or video, you will start to hear jitters and sound seems to echo itself .. Video would start to lag and become choppy.. Systems start to slow down and things seem to run very slow.. I have seen the power light on the PC start on but the touchscreen just go black (will not restart sometimes)..
Minor Issues (but could be related)
1) When running PC Hardware Diagnostic, they will come up with an error code in the past and that was warranted for a motherboard replacement (of course, they ship the box to the wrong location and I was in the middle of my wedding so I get to it now).. It was pertaining to PCI Express Status ICH9 PCI Express Root Port where it will generate an error code... Now, running the diagnostic... I will not get any error but PCI Express Root Port 3 & 5 do not show up on the diagnostic... Wouldn't that obvious show something that is a problem when there are 6 ports (which on the previous diagnostic that I can't grab past logs shows that). That is not warranted for a warranty work? Just a note, I got the fail test code (which was intermittent but keep happening and the tech support would not look at previous case.. Port 4 failed and a fatal device code)
2) Blu-Ray player will not run and their answer is that it is your Blu-Ray until they realize that I ran it on 3 different Blu-Ray player standalone, different Blu-Ray, and confirm DVD will work.. They still think it is a software issue until they can't deny my point when it will not read the Blu-Ray no matter what (they took control and confirmed it).. They believe the HP SmartDVD software was failing because of Win 7 and not Vista (even when I downgrade and confirm it works, I stated the software is the issue... Lone and behold, 2 months later they had an update that they refuse to admit I was RIGHT on the matter and done 15 hours of troubleshooting that they were wrong about)
3) Wireless Keyboard and Mouse lost connectivity even if the battery is not low... Just stop typing or omit letters.. This is considering the keyboard is literally in front of the touchscreen
4) Touchscreen is sensitive when it wants to be but won't in other... Constant issues there
This is why I have so much issue with support.. They seem to show that they will do anything to deny the issue.. Heck, I am a computer technian calling on the issue.. It ain't like I didn't troubleshoot on the matter... But they think we are all morons and when I prove them wrong, they will use any excuse to honor warranty... That is why it is amazing..

Look in your Settings > App Manager.
Tap Device Monitor.
Tap the Battery tab.
At the upper right, tap "Since Last Charge" to change to "Last 48 Hours".
What apps or processes are consuming the most battery power?
ALSO, in setting up your new Z30, are you syncing many contacts or calendar data from a connected email account?
Social accounts such as Facebook or Twitter?

Just updated to IOS 7 and two issues: First when I connect my iPhone to my computer I get this error message:itunes was unable to provider data from sync services".

Just updated to IOS 7 and two issues:
First when I connect my iPhone to my computer I get this error message:itunes was unable to provider data from sync services". I'm not sure what this really means...
The second issue is when I try to select "Manually Manage Music"
The iPhone "My iPhone" is synced with another iTunes libary on "MY-PC". Do you want to erase this iPhone and sync with this iTunes library? An iPhone can be synced with only one iTunes library at a time. Erasing and syncing replaces the contents of this iPhone with the contents of this iTunes library."
So... I don't want to do that, but I do what to be able to Manage my music. I'm not sure what it means by being synced to another iTunes unless it means to an older version of itunes?
Anyone have any ideas?

I cannot address the sync services error right now, but the error that you receive when you change from sync to manually manage music is what happens when you change. Once you change to manually manage music, it erases all of the music and will only put the music that you want on the phone, content that you manually drag over to it. See if this support document helps you out. http://support.apple.com/kb/HT1535
