Enabling extra tracing and logging on

how to enable extra tracing and logging on db? we can 't capture I/O errors on alert logs

Well,
That link is interesting, but here we're missing the replica part that Oracle deserves... don't you think?
At the time that blog was posted, seems that DBVERIFY was far from perfect and a lot of bugs have been fixed since then... Metalink Note:35512.1 tracks them and gives do's and don'ts regarding its use.
The erroneous behavior on false positive corrupted blocks, may correspond to one of the bugs listed on above note "newed blocks are flagged as corrupted", and corrected for 9.2.0.3 and 10.1.0.2; the blog don't give details about OS nor DB release, then we cannot generalize.
If somebody knows about an official statement from Oracle discouraging the use of DBVERIFY, please let us know...
For the OP: log an SR, trust Oracle.

SAP PI 7.3 Single stack- Set tracing and logging

Hi experts
We have configured a SOAP to SOAP sync scenario in SAP PI 7.3 single stack(Java Only).
I have sent some test messages from WSNavigator to PI .
But when i checked messages in adapter engine, it is showing*"Unable to retrieve payload or you don't have sufficient authorization to view the content" I am able to monitor payloads of Async messages.
How can we set Logging and trace levels in Single stack PI? I couldn't find any options in RWB os NWA.
Thanks,
Dhanish

Hello Dhanish,
As it was stated by Kenneth in his post, if you would like to see payload of a synchronous message in Message Display Tool (e.g. from Runtime WorkBench), you should set value of property messaging.SyncMessageRemover.removeBody of J2EE service XPI Service: Messaging System to 'false'. Please note that this affects only synchronous messages in final states (DLVD and FAIL).
Regarding the second part of your question - logging. In PI 7.3, you can persist the message in Adapter Framework in two ways - stage it or log it. Staging allows you to edit/restart the message later from the stage where the message was persisted and is relevant for asynchronous messages; logging allows you to only display the logged message and is relevant for both synchronous and asynchronous messages. Please also note that staging affects performance of message processing more greatly than logging, extensive staging (e.g. staging on several processing stages) can even be a reason of performance degradation for processed messages, so if you only need to display details of the message on different processing steps in Adapter Framework, logging should be sufficient. Both staging and logging can be configured using properties xiadapter.stage.conf (for staging) and xiadapter.logger.conf (for logging) of J2EE service XPI Adapter: XI.

Could you tell me what's the meaning of the logfile-path and log-level?

we are running an productive xml database. but it is not stable now. Sometime it would report resource conflict error while you access xmldb via http protocol. I read the database logs and listener logs, but no abnormal message could be found. So, I want to find more information from the xmldb logs. While I run select DBMS_XDB.cfg_get().getclobval() from dual, I found that there are several logfile-path and log-level tags and I guess that these would be xmldb logs. Does anyone know what's the meaning of these tags?

I wondered about that one often too. I didn't have a chance yet to investigate (but maybe Mark will elaborate a little here), my guess is that it / or will be a possibility to enable tracing regarding the protocols or servlets.
Though It look like if you enable it it will trace to the XML file defined in the xdbconfig.xml. I also guess that (because there is also a XSD counterpart) that one could create an resource that streams the errors into a XDB ftp or http or ... xmltype table based on these settings.
This would be great because it would mature the protocol server regarding functionality. You could enable the tracing and see what happens. Until now the documentation doesn't give much extra insight...

Configuration of Integration Engine Trace and Logging

Hi,
on XI we can configure tracing and logging of messages via SXMB_ADM / Conf Integr Engine / category RUNTIME parameter LOGGING or TRACE_LEVEL. I connected an application system (WAS 6.20) and cant find this parameters. They r not chooseable. Does anybody know why? Is there another functionality to customize the trace?

Enabling SQL Tracing for already connected session

Hi,
I've a requirement. i.e. my users are connected to db through schema making sessions( As multiple users are connected from single Schema). Now there are certian users which have to run batch jobs and I want to trace there SQL for tunning. I want to know how can I enable SQL tracing for specific user,session,id since it is difficult to trace exact user as multiple users are running the batch jobs.
I have a strategy to enable tracing at schema level. Can I do this while users are connected and running quries. As normally first we enable the tracing and then run the quries.
Kindly help me in working out this.
Regards,
Abbasi

You didn't post your Oracle version, but maybe you have DBMS_MONITOR available to you.
Hope this helps!

From SAP Notes
Log file:
A log file contains generally intelligible information for system administrators. The information is sorted by categories and is used for system monitoring. Problem sources or critical information about the status of the system are logged in this file. If error messages occur, you can determine the software component that has caused the error using the location. If the log message does not provide enough details to eliminate the problem, you can find more detailed information about the error in the trace file.
The log file is located in the file system under
"/usr/sap/[SID]/[instance]/j2ee/cluster/server[N]/log/applications.[n].log" for every N server node.
Access the file with the log viewer service of the J2EE visual administrator or with the standalone log viewer.
Trace file:
A trace file contains detailed information for developers. This information can be very cryptic and extensive. It is sorted by location, which means by software packages in the Java environment, for example, "com.sap.aii.af". The trace file is used to analyze runtime errors. By setting a specific trace level for specific locations, you can analyze the behavior of individual code segments on class and method level. The file should be analyzed by SAP developers or experienced administrators.
The trace file is located in the file system under
"/usr/sap/[SID]/[instance]/j2ee/cluster/server[N]/log/defaultTrace.[x].trc" for each N server node.
Access the file with the log viewer service of the J2EE visual administrator or with the standalone log viewer.

I just bought a (used) Iphone 3gs for wife and it had angry birds and $89 Navigation on it (I paid extra for it). Once updated and logged into my I-tunes it no longer works? How can I make those apps work?

Apple doesn't have anything to do with this other than enforcing the DRM protection. The developers of this content expect to be paid if someone wants to use their content. When you purchase content in the app store, you purchase a license to use the content. This license does not permit you or anyone else to resell or give this content away. The individual you purchased the phone from simply does not have the right to sell or give away any purchased content on the phone. You were deceived.

I purchased a used 2008 iMac. And although the previous owner said he deleted all of his information, his iCloud account is still the primary. I don't have a clue about what to do about it. I signed him out and logged in with my info, but still no go. Is there any way to eliminate his iCloud account and make mine the primary without rebooting it back to factory settings? There was an update, I believe, that I couldn't install because i didn't have his password that is what made me aware that his acct. was still active. I don't know what to do. Any help is greatly appreciated. Thank you.

Before buying a second-hand computer, you should have run Apple Diagnostics or the Apple Hardware Test, whichever is applicable.
The first thing to do after buying the computer is to erase the internal drive and install a clean copy of OS X. You—not the original owner—must do that. Changes made by Apple over the years have made this seemingly straightforward task very complex.
How you go about it depends on the model, and on whether you already own another Mac. If you're not sure of the model, enter the serial number on this page. Then find the model on this page to see what OS version was originally installed.
It's unsafe, and may be unlawful, to use a computer with software installed by a previous owner.
1. If you don't own another Mac
a. If the machine shipped with OS X 10.4 or 10.5, you need a boxed and shrink-wrapped retail Snow Leopard (OS X 10.6) installation disc from the Apple Store or a reputable reseller—not from eBay or anything of the kind. If the machine is very old and has less than 1 GB of memory, you'll need to add more in order to install 10.6. Preferably, install as much memory as it can take, according to the technical specifications.
b. If the machine shipped with OS X 10.6, you need the installation media that came with it: gray installation discs, or a USB flash drive for a MacBook Air. You should have received the media from the original owner, but if you didn't, order replacements from Apple. A retail disc, or the gray discs from another model, will not work.
To start up from an optical disc or a flash drive, insert it, then restart the computer and hold down the C key at the startup chime. Release the key when you see the gray Apple logo on the screen.
c. If the machine shipped with OS X 10.7 or later, you don't need media. It should start up in Internet Recovery mode when you hold down the key combination option-command-R at the startup chime. Release the keys when you see a spinning globe.
d. Some 2010-2011 models shipped with OS X 10.6 and received a firmware update after 10.7 was released, enabling them to use Internet Recovery. If you have one of those models, you can't reinstall 10.6 even from the original media, and Internet Recovery will not work either without the original owner's Apple ID. In that case, contact Apple Support, or take the machine to an Apple Store or another authorized service provider to have the OS installed.
2. If you do own another Mac
If you already own another Mac that was upgraded in the App Store to the version of OS X that you want to install, and if the new Mac is compatible with it, then you can install it. Use Recovery Disk Assistant to prepare a USB device, then start up the new Mac from it by holding down the C key at the startup chime. Alternatively, if you have a Time Machine backup of OS X 10.7.3 or later on an external hard drive (not a Time Capsule or other network device), you can start from that by holding down the option key and selecting it from the row of icons that appears. Note that if your other Mac was never upgraded in the App Store, you can't use this method.
3. Partition and install OS X
a. If you see a lock screen when trying to start up from installation media or in Recovery mode, then a firmware password was set by the previous owner, or the machine was remotely locked via iCloud. You'll either have to contact the owner or take the machine to an Apple Store or another service provider to be unlocked. You may be asked for proof of ownership.
b. Launch Disk Utility and select the icon of the internal drive—not any of the volume icons nested beneath it. In the Partition tab, select the default options: a GUID partition table with one data volume in Mac OS Extended (Journaled) format. This operation will permanently remove all existing data on the drive.
c. An unusual problem may arise if all the following conditions apply:
          OS X 10.7 or later was installed by the previous owner
          The startup volume was encrypted with FileVault
          You're booted in Recovery mode (that is, not from a 10.6 installation disc)
In that case, you won't be able to unlock the volume or partition the drive without the FileVault password. Ask for guidance or see this discussion.
d. After partitioning, quit Disk Utility and run the OS X Installer. If you're installing a version of OS X acquired from the App Store, you will need the Apple ID and password that you used. When the installation is done, the system will automatically restart into the Setup Assistant, which will prompt you to transfer the data from another Mac, its backups, or from a Windows computer. If you have any data to transfer, this is usually the best time to do it.
e. Run Software Update and install all available system updates from Apple. To upgrade to a major version of OS X newer than 10.6, get it from the Mac App Store. Note that you can't keep an upgraded version that was installed by the original owner. He or she can't legally transfer it to you, and without the Apple ID you won't be able to update it in Software Update or reinstall, if that becomes necessary. The same goes for any App Store products that the previous owner installed—you have to repurchase them.
4. Other issues
a. If the original owner "accepted" the bundled iLife applications (iPhoto, iMovie, and Garage Band) in the App Store so that he or she could update them, then they're irrevocably linked to that Apple ID and you won't be able to download them without buying them. Reportedly, Mac App Store Customer Service has sometimes issued redemption codes for these apps to second owners who asked.
b. If the previous owner didn't deauthorize the computer in the iTunes Store under his Apple ID, you wont be able to authorize it immediately under your ID. In that case, you'll either have to wait up to 90 days or contact iTunes Support.
c. When trying to create a new iCloud account, you might get a failure message: "Account limit reached." Apple imposes a lifetime limit of three iCloud account setups per device. Erasing the device does not reset the limit. You can still use an iCloud account that was created on another device, but you won't be able to create a new one. Contact iCloud Support for more information. The setup limit doesn't apply to Apple ID accounts used for other services, such as the iTunes and Mac App Stores, or iMessage. You can create as many of those accounts as you like.

Windows 7 takes 15 mins to log in and log off - School Enviroment

Hi All,
We're getting a very weird issue at present, our environment consists of 20
students with Windows 7 SP1. They login with roaming profiles. We've noticed
that when they login it takes up to 15 mins and logging off/shutting down takes
about 15 mins also. We have to re-image the PC's to get them working back to
normal however the problem just comes back!
What we've done so far,
Checked cables - all is ok
Used the Verbrose regedit on start-up to find that we needed to install
this hotfix from Microsoft (KB2537556) (worked for a week but then back to
normal, only for logging in not logging off)
Tried some GP changes
Local GP change - time waiting for network reduced to 15 secs then to 0 - no
change
Local GP change to remove all desktop items to see if that was causing
changes - no change
Only affects Student PC's which are used by all students
Any help would be great :)
MR

Hi,
First please check to see how big the student’s profiles are, what is the result if we compare it with teacher’s?
You can also enable boot logging in process monitor to find the cause of the slow logon, please refer to this blog.
The Case of the Veeerrry Slow Logons
http://blogs.technet.com/b/markrussinovich/archive/2012/07/02/3506849.aspx
And check whether you have Enabled “Delete cached copies of roaming profiles” policy setting, enable this policy will delay logoff as some yet-to-be-identified component in the OS is triggering Windows desktop search to cache settings on behalf of each locally
cached profile at logoff.

Odd situation with Safari after enabling account expiration and locking

Hi team,
i found the following puzzling situation today.
I enabled account expiration and locking in a workspace, thereafter all end users were requested to change their password as soon as they attempted to login to the application.
Some of these users went through this process smoothly and after changing the password they could log in. Others apparently succeeded in changing the password but the password change process is triggered again and again.
These users are receiving the following message after clicking on "apply changes" (p50 of app 4155).
ERR-1777: Page 50 provided no page to branch to. Please report this error to your application administrator.
When clicking on "restart application", they get the following additional screen:
You have successfully logged out. You have been redirected here after using a logout link provided by an authentication scheme. To redirect to a page in your flow instead, do something like this:
Create a page in your flow and give it an alias PUBLIC_PAGE.
On the Flow Builder page attributes page, select the "Yes - This page is public" Public Page attribute.
Change the logout URL in your authentication template to redirect to this new page after the logout procedure executes. For example, using the API, make your logout URL:
wwv_flow_custom_auth_std.logout?p_this_flow=&FLOW_ID&p_next_flow_page_sess=&FLOW_ID:PUBLIC_PAGE:&SESSION
Note that the suggested URL uses a somewhat outdated syntax lacking the period after the application items, so you might want to revise it for future releases.
After various tests it turned out that the problem is in the browser (don't ask me what).
Safari users do not succeed in changing their passwords through page 4155:50, while Firefox users do.
I have a password change page inside my application though and everybody can change their password from there successfully.
Also, after changing the password using Firefox, Safari users can log in without problems whatsoever.
So the final question is: what's wrong with page 50 of application 4155 when run from Safari on Mac?
It happened with Apex 3.1.2 and Safari Version 3.2.1 (5525.27.1)
Thanks!

Scott,
that was exactly what i was about to do yesterday night, but at the post office i realized i didn't know the address :D
Then, fortunately for me, but regrettably for you (hehehe), i realized that Safari is not the culprit.
For some reason people using Safari were always submitting the page with enter, while Firefox users were submitting with the button.
I made a test and Safari is fine as long as you click on the button, the bug is in the submit through the enter key.
Thanks and sorry about the mac air, may be the next time!

Hi,
I invoked New Mesage

I clicked on the "to" name and got this

I don't get a Bonjour Option here.
I do get a Jabber ID showing up for them but for soem reason it does not list my "From" account.
I would say that I have seen multiple "To"s and the same for the "From" choices and I think I have seen the Bonjour one listed.
However the "To" And "From"s don't seem to match and it appears you can iMessage Jabber names/ID or Jabber AIM names (which you can't in either case)

Enabling SQL Tracing for an instance

Hi,
I am aware that SQL_TRACE init parameter is deprecated :
Oracle® Database Upgrade Guide
10g Release 2 (10.2)
Part Number B14238-01
Initialization Parameters Deprecated in Release 10.2
SQL_TRACE
So I searched the recommended way of enabling sql tracing for an instance and I found :
Oracle® Database Performance Tuning Guide
10g Release 2 (10.2)
Part Number B14211-01
20.4.2 Step 2: Enabling the SQL Trace Facility
You can enable the SQL Trace facility for an instance by setting the value of the SQL_TRACE initialization parameter to TRUE in the initialization file.
Well, the Tuning guide should not mention deprecated parameter, should it?
Anyway, I found later that the recommended way is to use
exec DBMS_MONITOR.DATABASE_TRACE_ENABLEPlease update your tuning guide.
Cam on rat nieu ;-)

Laurent,
Sorry to post a reply after nearly 2 years :-)
But:
Does dbms_monitor.database_trace_enable() only trace existing sessions or does it also enable tracing for all new sessions?
I've been consulting the documentation and searching on the Internet but I can't determine this.
Cheers & thanks,
Colin

Please contact your system administrator to resolve the problem'
It is a brand new iMac and running Lion OSX
Any ideas on how to solve would be gratefully received?

Followed the directions on this page and it worked!
http://forums.macrumors.com/showthread.php?t=1102423
Part One - Turn on SSH (in the admin panel)
[1] Go to to http://mybookworld.local
[2] login: username will be admin, password will be whatever you have setup. If you can't remember it should be in your Mac OS X keychain (Utilities > Keychain Access, search for "mybookworld"). If you have not changed if from the default the password will be admin as well.
[3] Switch to advanced mode.
[4] From the System tab, pick Advanced.
[5] Enable SSH Access, and click submit.
[6] Click on the network tab and then the LAN button
[7] Make a note of the IP address
Small, maybe obvious, but nevertheless important point: For the install to work, your NAS needs to be connected to a router with internet access.
Part Two - Install netatalk2.2
[8] Open Terminal.app (Utilities > Terminal)
[9] Enter the following command (substitute in 127.0.0.1 for the actual IP address you noted down in step 7), then hit return:
Code:
ssh [email protected]
[10] When prompted, enter the ssh password (will be welc0me).
[11] You are now going to download the installer. Enter the following command, then hit return:
Code:
wget http://mybookworld.wikidot.com/local--files/netatalk2-2-on-whitelight/install_netatalk.sh -O install_netatalk.sh
[12] Once completed, you will need to run the installer. Type:
Code:
sh install_netatalk.sh
[13] You will be asked a number of question during install, answer yes to all. When asked about the "DHX2 login process", I opted to install the modified version, so I can confirm it works.
[14] Once the box has restarted, you should be able to connect to your afp shares and continue to use Time Machine.

How to design SQL server data file and log file growth

how to design SQL DB data file and log file growth- SQL server 2012
if my data file is having 10 GB sizze and log file is having 5 GB size
what should be the size in MB (not in %) of autogrowth. based on what we have to determine the ideal size of file auto growth.

It's very difficult to give a definitive answer on this. Best principal is to size your database correctly in advance so that you never have to autogrow, of course in reality that isn't always practical.
The setting you use is really dictated by the expected growth in your files. Given that the size is relatively small why not set it to 1gb on the datafile(s) and 512mb on the log file? The important thing is to monitor it on an on-going basis to see if that's
the appropriate amount.
One thing you should do is enable instant file initialization by granting the service account Perform Volume Maintenance tasks in group policy. This will allow the data files to grow quickly when required, details here:
https://technet.microsoft.com/en-us/library/ms175935%28v=sql.105%29.aspx?f=255&MSPPError=-2147217396
Also, it possible to query the default trace to find autogrowth events, if you wanted you could write an alert/sql job based on this
SELECT
[DatabaseName],
[FileName],
[SPID],
[Duration],
[StartTime],
[EndTime],
CASE [EventClass]
WHEN 92 THEN 'Data'
WHEN 93 THEN 'Log' END
FROM sys.fn_trace_gettable('c:\path\to\trace.trc', DEFAULT)
WHERE
EventClass IN (92,93)
hope that helps
