Issue connecting multiple servers in parallel using wlst
Hi,
I have requirement to write a jython script to connect multiple weblogic servers and generate some reports.
I am importing wlstModule(import wlstModule as wl) in the scirpts.
I would need multiple users to be able to run the script from a webpage in parallel.The website is based on java.
1. My initial thoughts were to create a new thread for each user request. But since the global variable cmo is shared between the jython threads,i believe it wouldn't work.
2. My second option is to create a new process for each user.This way each process would have its own independent global namespace.
Even though this should work,it dosen't look the cleanest way to do.
Does someone have any better idea?
You can use the Distribution Monitor for that purpose. Check note 855772 - Distribution Monitor

How to send multiple files in parallel using ftp with single connection
Hi.
i have written code for file upload manager using ftp..
it perfectly working with sequence file uploading in single connection..
And i tried to upload multiple files with parallel processing in a single connection.... but it is not working properly.. i also used thread concept
but single file only transfered and connection refused...
my code here...
//////////////////// main class //////////////////////////////////////////
ftp.connect();
ftp.login();
String [] archivos = new String[100];
File dir = new File("C:\\Files Uploading\\");
archivos = dir.list();
for (int s=0; s<archivos.length;s++)
//Start Data Transfer Here
new DataTransfer(archivos[s]).start();
Thread.sleep(1000);
/////////////////////// thread class ////////////////////////////////
class DataTransfer extends Thread
String FileName="";
String LocalPath="",RemotePath="";
public DataTransfer(String fname)
FileName = fname;
LocalPath = "C:\\Files Uploading\\" + FileName;
RemotePath = FileName;
System.out.println(LocalPath);
public void run()
System.out.println("DataTransfer Started");
/File Transfer Here
try
FileInputStream input = new FileInputStream(LocalPath);
Ftp_Client.storeFile(RemotePath,input);
System.out.println("Successfully sent : " + RemotePath);
catch (Exception exc)
System.out.println(exc.getMessage());
System.out.println("DataTransfer Ended");
}otherwise tell me any other alternate wayAnd i tried to upload multiple files with
parallel processing in a single connection....
but it is not working properly.FTP isn't a multiplexing protocol. How could it work at all? -
How to acquire data through multiple channels in parallel using PXI 6070 E, PXI 4071 and LabVIEW?
Hi,
I am using NI LabVIEW, NI PXI 4071, and NI PXI 6070E to measure current through a variable resistance. Now, I am using one channel from SCB-68, but I want to add another channel in parallel so that I can have two resistors instead of one that I cam measure current through them.
I have attached a Pdf file showing the setup for hardware in use and LabVIEW code also.
Can anyone look at these files and give me guide lines or ideas that can help me resolving this issue, please.
Thanks in advance.
Best Regards,
Shaheen.
Solved!

IV copy for HS.vi 55 KB
Layout of NI Cards.pdf 248 KBYour 4071 can only do one measurement at a time. Your DAQ cannot measure resistance either nor has it got any analogue inputs.
However, you could use a multiplexer and multiplex your 4071 DMM. This wont give you simultaneous measurements but can acquire data one after the other, the speed is obviously dependent on the multiplexer you choose!
Hope this helps.

Issues connecting to sql 2005 database using Oracle sql developer 1.2
I just installed the sql developer and was trying to use the quick migrate to try a migration from a sql server to oracle..
I am getting the following error message when i click on the retrieve database after entering the database credentials
Status : Failure net.sourceforge.jtds.jdbc.driver
I am getting another error message when i click on the 'test' button
Status: Failure - Unable to find driver: net.sourceforge.jtds.jdbc.driver
I downloaded the jtds driver from source forge and i am wondering what I should do to get the sql developer to make successful connections to sql server.
Any help is appreciated.
ThanksI have the same issue with both version 1.1.3 of the SQL developer and the latest version(1.2.1). I have added the jar file path in tools->preferences->Database->Third Party etc...
I got the jar file from this download: jtds-1.2.2-src.zip
I get this error when trying to connect to an sql server:

Email body of HTML or RTF messages are rendered in ASCII characters after upgrading to Firefox 5 when viewing email in MS Outlook Web Access (OWA) light from MS Exchange 2007 servers. Issue is repeatable with two entirely different Exchange systems.
Text email renders OK. Work around is to forward email (in use MS-IE).You are welcome. I'm glad you got it back up.
(1) You say you did the symbolic link. I will assume this is set correctly; it's very important that it is.
(2) I don't know what you mean by "Been feeding the [email protected] for several weeks now, 700 emails each day at least." After the initial training period, SpamAssassin doesn't learn from mail it has already processed correctly. At this point, you only need to teach SpamAssassin when it is wrong. [email protected] should only be getting spam that is being passed as clean. Likewise, [email protected] should only be getting legitimate mail that is being flagged as junk. You are redirecting mail to both [email protected] and [email protected] ... right? SpamAssassin needs both.
(3) Next, as I said before, you need to implement those "Frontline spam defense for Mac OS X Server." Once you have that done and issue "postfix reload" you can look at your SMTP log in Server Admin and watch as Postfix blocks one piece of junk mail after another. It's kind of cool.
(4) Add some SARE rules:
Visit http://www.rulesemporium.com/rules.htm and download the following rules:
70sareadult.cf
70saregenlsubj0.cf
70sareheader0.cf
70sarehtml0.cf
70sareobfu0.cf
70sareoem.cf
70sarespoof.cf
70sarestocks.cf
70sareunsub.cf
72sare_redirectpost
Visit http://www.rulesemporium.com/other-rules.htm and download the following rules:
backhair.cf
bogus-virus-warnings.cf
chickenpox.cf
weeds.cf
Copy these rules to /etc/mail/spamassassin/
Then stop and restart mail services.
There are other things you can do, and you'll find differing opinions about such things. In general, I think implementing the "Frontline spam defense for Mac OS X Server" and adding the SARE rules will help a lot. Good luck! -
Issues connecting multiple machines wirelessly to WRT54G router
I have a WRT54G router and have one wired desktop, two laptops that connect fine and then I have a netbook and another desktop with wireless adapter I am having issues with connecting. I used the wizard and set each machine up with the downloaded executable, it says it works but when I try to connect I get unable to connect to wireless network message. ANy ideas? Any help is greatly appreciated
You have one computer connected with the cable and 2 wireless computers working fine. That means the router is working fine.
I think you should check the wireless settings of the router first.
You have one computer connected to the router with the Ethernet cable. Open the setup page of the router and go to Wireless tab. Check the wireless network name. Go to wireless security sub tab. Check the wireless security mode and make sure that you have the correct password of your wireless network. Go to Wireless MAC address filter sub tab and make sure that it is disabled.
Try to connect to the wireless network again and see if that works. -
Multiple servers in parallel export/import question
Hello all,
We plan to use parallel export/import using distribution monitor, and want to use several servers in export and also in import.
The export_monitor.cmd.properties has FTP option ftphost, whic is the hostname of the import server, which looks like it will only use 1 application server (AS) from the source system and 1 in the AS in the target system -
- is this true or can we use more AS in both export and import?
- in the export, how to specify the AS to use?
- in the export, how to specify more than 1 AS?
- in the imprt, how to specify more than 1 AS ?
Thanks,
TerryYou can use the Distribution Monitor for that purpose. Check note 855772 - Distribution Monitor

Run Multiple SSIS Packages in parallel using SQL job
Hi ,
We have a File Watcher process to determine the load of some files in a particular location. If files are arrived then another package has to be kick-started.
There are around 10 such File Watcher Processes to look for 10 different categories of files. All 10 File Watcher have to be started at the same time.
Now these can be automated by creating 10 different SQL jobs which is a safer option. But if a different category file arrives then another job has to be created. Somehow I feel this is not the right approach.
Another option is to create one more package and execute all the 10 file watcher packages as 10 different execute packages in parallel.
But incase if they don’t execute in parallel, i.e., if any of the package waits for some resources, then it does not satisfy our functional requirement . I have to be 100% sure that all 10 are getting executed in parallel.
NOTE: There are 8 logical processors in this server.
(SELECT cpu_count FROM sys.dm_os_sys_info
i.e., 10 tasks can run in parallel, but somehow I got a doubt that only 2 are running exactly in parallel and other tasks are waiting. So I just don’t want to try this option.
Can someone please help me in giving the better way to automate these 10 file watcher process in a single job.
Thanks in advance,
Raksha
RakshaHi Jim,
For Each File Type there are separate packages which needs to be run.
For example package-A, processes FileType-A and package-B processes FileType-B. All these are independent processes which run in parrallel as of now.
The current requirement is to have File Watcher process for each of these packages. So now FileWatcher-A polls for FileType-A and if any of the filetype-A is found it will kick start package-A. In the same way there is FileWatcher-B, which looks for FileType-B
and starts Package-B when any of FileType-B is found. There are 10 such File Watcher processes.
These File Watcher Processes are independent and needs to start daily at 7 AM and run for 3 hrs.
Please let me know if is possible to run multiple packages in parallel using SQL job.
NOTE: Some how I find it as a risk, to run these packages in parallel using execute package task and call that master package in job. I feel only 2 packages are running in parallel and other packages are waiting for resources.
Thanks,
Raksha

Renew Machine Certificate for multiple Servers
Hi,
We have Windows 2003 Enterprise CA which issues certificates to servers which are used for various purpose like Wifi Authentication, Secure RDP. We have checked that the certificates are going to expire within few weeks. We want to renew certificates before
expiry but the number of servers is high so we cannot do it manually by logging into each server.
We doesn't have ACRS enabled for computer certificates and even if we configure it now that will not help.
Is there a way to renew the certificates for all the servers remotely.On Tue, 15 Apr 2014 11:39:43 +0000, Sukhwin08 wrote:
We already have auto-enrolment enabled through GPO. The settings are as follows
Automatic certificate management........ Enabled Option Setting Enroll new certificates, renew expired certificates, process pending certificate requests and remove revoked certificates .........Enabled
Update and manage certificates that use certificate templates from Active Directory ..........Enabled
I think that you're confusing Automatic Certificate Request Services and
autoenrollment. In your first post in this thread you mention ACRS, however
the above settings are for autoenrollment. ACRS is only for certificates
that are based upon V1 certificate templates and then only for machine
certificates. Autoenrollment on the other hand does not work for anything
less than V2 certificates and supports both machine and user certificates.
If you're using V1 certificate templates then you can set autoenrollment
settings in a GPO and it will not have any impact at all.

Issue while starting AdminSerever using wlst commands
Hi, I am facing issue while trying to start the AdminServer and Managed Server via nodemanager using wlst commands. I have installelled WebLogic 11g on windows 2008 R2. Mentioned below are the steps that I followed:
1) In Nodemanager.properties files I set following parameters to true. I did this, so that nodemanager can start the server in case of crash.
CrashRecoveryEnabled=true
StartScriptEnabled=true
2) started nodemanager and then started AdminServer from the command prompt as follows:
nmConnect('weblogic','password','10.23.226.58','5556','IMDomain','E:\Oracle\Middleware\user_projects\domains\IMDomain','ssl')
nmStart('AdminServer')
I dont see any errors but it seems the AdminServer do Not start properly as in the cmd window I don't see any 'started successfully' message - the message remains as *"Starting AdminServer..."*
However in the adminServer logs I see that the status is Running (refer logs at the end) and I can also see it as Running in weblogic console.
I really didnt care if its not giving a success message in cmd window but the problem occurs when I start the managedServer. After starting the managed server in about 10 minutes, there is a stuck thread. (I guess it is 10 mins because Stuck Thread MaxTime value is 600).
If I set StartScriptEnabled=false, and start by directly running the startweblogic.cmd then it works fine.
I am struggling with this for last 1 week, appreciate any help.

"We are experiencing an issue connecting to the Adobe Color CC servers"
Keep getting the error "We are experiencing an issue connecting to the Adobe Color CC servers" every time I try to access Color CC, I am signed into the Creative Cloud.
Has anyone else had this problem?I have been getting the same issue for about a week now. However if I create a new Adobe ID with another email address, that email doesn't have the issue. Does anyone know what might be causing this? I have tried clearing cookies and using multiple browsers and nothing seems to work.

Unable to connect to Admin Server from second machine using WLST
Hello,
PROBLEM
Can't get WLST to connect to admin server from 2nd host to register the domain.
SETUP
I have 2 Centos VMs running on Oracle Virtual box in a single laptop. Both the VMs use "Bridged Networking".
VM-1 CONFIG
cat /etc/hosts
192.168.1.17
dom1 dom1.my mac1
192.168.1.51
centos2 mac2
VM-1 hosts admin server & one managed server
VM-2 CONFIG
192.168.1.51
mac2
192.168.1.17
centos1 mac1
VM-2 hosts just one managed server
I can start up admin on VM-1 fine. The node manager is reachable too. Both the VMs are can be pinged from each other. I can also telnet to the admin server's port ( telnet 192.168.1.17 7001) from the second server.
My HOST OS is Windows 7. I can ping from windows to both the VM IPs too. The reverse is working fine as well.
I've tried both mechanisms of copying the whole domain from machine 1 over to machine2 & also using the pack.sh/unpack.sh combinations to transfer the domains.
When I invoke WLST, this is what happens
./wlst.sh
CLASSPATH=/apps/prod/appservers/weblogic/wls_10_3_6/patch_wls1036/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/apps/prod/appservers/weblogic/wls_10_3_6/patch_ocp371/profiles/default/sys_manifest_classpath/weblogic_patch.jar:/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.25.x86_64/lib/tools.jar:/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/server/lib/weblogic_sp.jar:/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/server/lib/weblogic.jar:/apps/prod/appservers/weblogic/wls_10_3_6/modules/features/weblogic.server.modules_10.3.6.0.jar:/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/server/lib/webservices.jar:/apps/prod/appservers/weblogic/wls_10_3_6/modules/org.apache.ant_1.7.1/lib/ant-all.jar:/apps/prod/appservers/weblogic/wls_10_3_6/modules/net.sf.antcontrib_1.1.0.0_1-0b2/lib/ant-contrib.jar::/apps/prod/appservers/weblogic/wls_10_3_6/utils/config/10.3/config-launch.jar::/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/common/derby/lib/derbynet.jar:/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/common/derby/lib/derbyclient.jar:/apps/prod/appservers/weblogic/wls_10_3_6/wlserver_10.3/common/derby/lib/derbytools.jar::

Also, I can't invoke weblogic.Admin from the second VM despite setting the environment using "setWLSEnv.sh". i get the error "Error: Could not find or load main class weblogic.Admin".
Please could you help me fix this? I've spent 3 days now trying numerous things without much luck :-(
Kind RegardsHi Raj,
Issue is with NM registry with domain home. Please follow the below steps and let us know the status.
1 . Check whether the node manager port ( default 5556 ) is opened for communication on both Admin and Managed server.
2 . After opening the port - We would need to enroll the node manager home with domain home to establish the communication between Admin and Managed server.
a . Start the Administration Server.
b . Using the Administration Console update the Node Manager credentials from the Advanced options under domain_nameArrow symbolSecurityArrow symbolGeneral.
c . Invoke WLST and connect to an Administration Server using the connect command. See Using the WebLogic Scripting Tool in WebLogic Scripting Tool.
d . Run nmEnroll using the following syntax:
nmEnroll([domainDir], [nmHome])
Running nmEnroll() ensures that the correct Node Manager user and password token are supplied to each Managed Server. Once these are available for each Managed Server, you can use nmConnect() in a production environment.
Note: You must run nmEnroll() on each machine that is running a Managed Server. Additionally, you should run nmEnroll() for each domain directory on each machine.
For more info : General Node Manager Configuration
Thanks
