Could not obtain an instance of KeyTabKeytab is corrupted

Hello,
We have been experiencing problems with server and JVM performance since we enabled SSO in our application.
We are using WebLogic 10.3 and BEA JRockit(R) (build R27.6.3-40_o-112056-1.6.0_11-20090318-2103-solaris-sparcv9, compiled mode).
After startup everything is running smoothly but after some time server stops responding:
•     stops logging,
•     stops serving pages,
•     stops responding to web services.
Also it’s using a lot of CPU time.
Here is an example of last lines of console logs (I’ve skipped some configuration details replacing it with <…>):
Debug is true storeKey true useTicketCache false useKeyTab true doNotPrompt false ticketCache is null isInitiator false KeyTab is <…> refreshKrb5Config is true principal is <…> tryFirstPass is false useFirstPass is false storePass is false clearPass is false

We have found the following bug description http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6919610 and it looks like our problem (at the end of log lines are doubled which suggests two parallel threads and “Could not obtain an instance of KeyTabKeytab is corrupted” is exactly what would be logged in such a situation).
But is it possible that this causes the server stop responding?
If it is, do you have any suggestions of workarounds? (I don’t think that people are waiting for fix to come in next JRockit version ;-)
Also recently we’ve had Segmentation Fault with no dumps (but maybe it’s some other issue) .
Thank's for any help,
Kuba

Could not obtain connection to the central environment.

Hi,
I have just started using iSetup on 11.5.10.2.
Initially I intend to use the same instance as source and central one.My understanding is that Source,Central and Target Instance are more of logical grouping and the same instance can be mapped for all the three.
I have mapped the instance that I am using as Source Instance and after that I try to run an Extract.The report is ending with error "Could not obtain connection to the central environment".
Kindly guide on what needs to be done to map the same instance as Source,Central and Target.
Do i need to map in thrice?

Changing from dev to standard edition causes "Could not obtain information about Windows NT group/user error code 0x6e."

Hello,
We recently upgrade our SQL Server 2012 SP1 (64bit) dev edition to standard edition, after we purchased the required licence and it was deployed in production.
Since the edition change, we are now receiving the following error, with some of our jobs, which have an e-mail step in them, which is causing the jobs to fail.
Msg 14661,Level 16, State 1, Procedure sp_send_dbmail, Line 517
Query execution failed: Msg 15404, Level 16, State 19, Server BL-SVR15, Line 1
Could not obtain information about Windows NT group/user 'BLUELIZARD\savaa', error code 0x6e.
Any ideas how to fix this issue? We were also having a similar error, when executing the jobs, but changing the job owner to SA has fixed this issue.
Thanks,
Andy.

Hi,
Which user account you used for SQL Server service, domain account or local account?
If it is domain account, are you able to log in to a machine with it?
Make sure that the password of account is not expired.
Also, grant the user Allowed to Authenticate permission and see how it helps.
Refer to the below article:

I add 3 SCSI vmware disks. and then use them as a raw device. no ASMLib is used.
I refer below tutorial
[http://www.oracle-base.com/articles/10g/asm-using-asmlib-and-raw-devices.php]
That tutorial picks up after you created the disks.
How did you create the virtual disks attatched to your vm? What are its properties - from VMWorksation's perspective.
How did you create the "copy" of the vm?
It depends on how you actually created the disks, at the vm level, not the partitioning and formatting at the vm's OS level. I've used Tim's tutorials myself on some other ASM related projects, and he typically has you create the ASM disks as 'sharable', which would mean they would not copy necessarily copy with the vm. I've not played around the with variants much, but I'm pretty sure what you are seeing is a result of either the way the disk was created in the original vm, or the way you made the copy of the vm, or both.
Take a look at the machine properties of the two vms in the VMWorkstation control panel, looking at the HDD definitions. Compare and contrast.Hi EdStevens,
My problem resolved with below steps. Thanks fro your replies.

chris

Really would help to know what operating system you are using...
When you set up the disks for use with ASM, did you stamp them with ASMLIB? If not, did you configure device persistance with udev? Without using one of these methods, the disk identification can change when a node is restarted, and ASM is then unable to locate the disks.

Suppress Powershell Warning in agent job "WARNING: Could not obtain SQL Server Service information"

Hi
I get this warning running through powershell_ise but through sql agent it just errors out.
The code does everything it is supposed to and I tried everything to completely resolve the warning to no avail.
How do I supress it so sql agent wont error out running powershell code?
Thanks!
WARNING: Could not obtain SQL Server Service information. An attempt to connect to WMI on 'server_name' failed with the following error: Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
Warning only present when it connects to remote servers, it doesn't produce it for local server. And it does get all info from the remote servers.
Paula

Hi paulata,
According to your description, when you run powershell scripts about the remote machine
in SQL Server Agent job, the warning error will occur. “The common error message is Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED)).” This suggests that your credentials aren't sufficient for accessing the
remote system. If you have an account that has sufficient permissions for the query, there's a simple workaround for this problem in the form of PowerShell's Get-Credential command and the script's Credential parameter. I recommend you check if your account
has permission on remote machine and it can execute the powershell scripts.
In addition, if you want to run query statement on the remote machine , I recommend you create Linked Server, then do some related operations. There is a similar issue about access denied, you can review the following article.

Could not start OC4J instance.. Exception in thread "OC4J Launcher"

Though I made the modification and re-start the OC4J instance, I could see the same error and behavior.
Can anyone help me to resolve this issue please?
Regards,

This is bit strange. It should work. I tested and works fine for me.
Can you remove the entry from opmn.xml and make sure no typo in server.xml and try again. You might want to reload OPMN (opmnctl reload) and then try restarting OC4J (opmnctl startproc ias-component=OC4J).
Note that value (-DcheckForUpdates) set in opmn.xml overrides the value set in server.xml:

Hi
I am getting the same error, but when i tried to retrieve the process instance from nwa I see the process instance to be missing. I could not trace the process instance.
Can you please tell me where else can i look for the process instance.

I encounter the same issues when using the TimerTask to access the JNDI tree. I have found success when I move my business logic to an EJB and call my EJB from my TimerTask. It's a bit more work, but not much. The EJB inherits it's identity based on it's configuration and has no trouble accessing the JNDI tree whenever it's called. Try this and see if your problem doesn't go away.
Hope this helps,

IBooks crashes on startup - Could not obtain real path to the container root

I also pulled the logs from the console

Any ideas?

Start "Terminal" and type:

It will add a missing folder that is needed.
iBooks should now launch.
I've had a lot of similar errors after restoring from Time Machine. I've also had to do the same things for quick look, "com.apple.quicklook.ui.helper" and "com.apple.lateragent", and iPhoto "com.apple.iPhoto".

Then i decided to restore my iphone and i have download almost 4 firmware files (iPhone7,1_8.3_12F70_Restore.ipsw and iPhone7,1_8.0_12A366_Restore.ipsw and iPhone7,1_8.0.1_12A402_Restore.ipsw and fourth one is iPhone7,1_8.2_12D508_Restore.ipsw.part) and restore (by holding shift in itunes and selecting file ) using itunes ( which is current version 12.1.2.27 64 bit) but for everytime two of them(while extracting ) which are (iPhone7,1_8.3_12F70_Restore.ipsw and iPhone7,1_8.2_12D508_Restore.ipsw.part) it says "Iphone "Iphone" could not be restored becuse firmware file was corrupted please disconnect and try again later" .i have tried to download "iPhone7,1_8.3_12F70_Restore.ipsw " manually and via itunes (when i download and restore using itunes it says
"There was a problem downloading the software for the iPhone ''iPhone'' A unknown error occured (9006).
Make sure your networks settings are correct and your network connection is active, or try again.''

I have the current version of itunes, but when I go to update my ipod, I am getting an error message that says that it could not back up because the backup was corrupt or not compatible with the iPod. This is the first time trying to backup.
