Loadjava hangs - exclusive lock on sys.javasnm$

We upgraded from Oracle 9.2.0.4 to 9.2.0.5 (using export then import of the entire database) and have found that our user java classes that compiled fine in 9.2.0.4 aren't as lucky in 9.2.0.5. When we use "loadjava" to recompile the jar files, some compiles are successful and others hang. When we investigate the "hanging" ones we find an exclusive lock on sys.javasnm$. The only session doing a loadjava compile is mine. We kill the Oracle session, the exclusive lock goes away, we compile a few more jars successfully, then the "hanging" begins again. Can anyone explain what is going on? Thanks in advance.

Solution - We were missing the DROP SYNONYM permission for the Oracle User we were importing the java code for. Once that was in place the locks were no longer an issue.

Hello HaithamOkeely,
We've an article that provides the following troubleshooting steps that may help stabilize your iPhone.
If the device is unresponsive or if certain controls aren't working as expected, restart your device.
If the device remains unresponsive or does not turn on (or power on), reset your device.
If there is no video or if the screen remains black, verify that the device has enough charge to turn on:
If you are using an iPad, ensure that it's connected to the USB Power Adapter supplied with the device.
Let it charge for at least twenty minutes, then see if it starts normally.
If there is no image on the screen, press the Sleep/Wake button to attempt to wake the device.
If the screen displays a red battery icon, continue charging the device until the battery is fully charged. Learn more about charging iPhone and iPod touch, or iPad.
If the above steps do not resolve the issue, or the if the screen remains black or shows a persistent Apple logo, try restoring with iTunes:
Connect the device to your computer and open iTunes.
If the device appears in iTunes, select and click Restore on the Summary pane. Learn more aboutrestoring iOS software.
If the device doesn't appear in iTunes, try to force the device into recovery mode, and then restore it.
If the above steps do not resolve the issue, contact Apple.
iOS: Not responding or does not turn on

My ipad2 hanged while lock, i can't reset or turn it off. What will i do!

My ipad2 hanged while lock, i can't reset or turn it off. What will i do?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

GTT table getting Row Exclusive lock

I have a procedure which loads a table which is used for reporting.
Currently it is a single process which picks up most of the data after joining 2-3 big tables(around 70-80GB) and then loading the main table.
The joins are on PI and also partitions are also being used. Then a lot of updates are done on the main table to update other columns which are being picked from different tables.
As the processing is happening on huge amount of data(around 1M), so processing is taking a lot of time.
This process is taking around 40-45 minutes.
I am planning to use parallelism to run it in 75 sessions. So the initial big insert will be faster and later on all the updates will be done on smaller chunks which will benefit the performance.
I planned to use GTT table so that i dont have to create 75 temp tables for each sessions.
But while using GTT table(ON COMMIT DELETE ROWS) in parallel sessions, i am seeing that the GTT table is getting Row Exclusive lock and the time taken by overall process is increasing by lot.
So i tested by using 75 temp tables. There i saw that the performance has increased by lots as assumed initially.
Please let me know if there is any other way or how to remove the locks on GTT table.

First you should question why you think you need 75 GTT.
Also your question contains no useful information
(no four digit version of Oracle, no OS, no number of processors) , this paragrah
Currently it is a single process which picks up most of the data after joining 2-3 big tables(around 70-80GB) and then loading the main table.

This process is taking around 40-45 minutes.tells nothing,
so basically your questions boils down to
- Hey I come from a sqlserver background (this is just an educated guess), how can I find a workaround to wreck Oracle to make it work like sqlserver.
75 parallel sessions on say 4 to 8 processors is a very bad idea, as these sessions will be simple competing for resources.
Also a row exclusive lock is just that: a row level lock. This isn't a problem, usually.

HI,thanks very much.
Because our data is very huge,so some leader login the system will get the error.I check the st22,It realy found the error:
Time limit exceeded.
The program "SAPLRHDB" has exceeded the maximum permitted runtime without
interruption and has therefore been terminated.
If I should increase the system profile parameter "rdisp/max_wprun_time"?
Can else I should turn other parameter?

Error: the database could not be exclusively locked to perform the operation in sql server 2008 ?

I am trying to rename the database but i am getting below exception while doing it-->
Error: the database could not be exclusively locked to perform the operation.(Microsoft Sql Server,Error 5030)
Thanks.

as mentioned earlier by both these users just wait for all the connections to go and then try- it will succed
or else if it is dev\Uat environment & you can kill the conenctions - make the changes (use this as last option)
i was just wondering if you are connected to the same DB? If yes change your context to master(means connect to master DB ) and then issue this command.

Cmp exclusive locking

hi, is it possible to implement exclusive locking in cmp 2.0 ?
just like FOR ... UPDATE statement in oracle ?
help please

After having discussion with Mitesh, here is what we think
There are 2 ways to handle this issue
Approach 1:
Using UserTransaction in the servlet
ut = (UserTransaction) ic.lookup(
"java:comp/UserTransaction");
ut.begin();
findAll();
doProcessing();
ut.commit or rollback();
In this case all rows will be locked till we do commit or rollback
Approach 2:
Using BMT/CMT (Bean Managed Transaction/ContainerManagedTransaction) for session bean as a middle layer between servlet and CMP
For CMT in session beans
Now session bean will have a business method(having Required transaction attribute in CMT) doing
busineessmethod() {
findAll()
doProcessing()
BMT in session bean is similar to UserTransaction explained in servlet, only difference in getting usertransaction
For BMT , we need to do
context.getUserTransaction();
Please refer to samples/transaction samples for details

IllegalStateException thread tries to release exclusive lock LockingManager

Hello,
I'm having this error,
java.lang.IllegalStateException: Illegal state: thread tries to release exclusive lock on ApplicationSession which it hasn't acquired! Details: LockingManager(ThreadID:89, threadName: HTTP Worker @1298613650, session lock: null, current request: company.com.pe/wd_hrsolmovpil_v1/Wdhrsolmovpilv1)
Any of my web dynpros, even the uwl doesn't work.
This happened after I tried to deploy project. Everything was working fine, but now ... I have this. I've restarted the server, but nothing happens.
Please, anyone knows how to solve this? Any ideas?

Hello,
The problem was because the WAS has the parameter DefaultExpirationTime seted in -1 of all the Web Dynpros (sap.com/tcwddispwda). It only accepts positive values. I had to login through Telnet and execute the parameter,
add webdynpro

Updating a row in table exclusive lock on entire table

Hi
We have table master table and few child tables .
when we try to update a row in master table , it is locking entire table
i.e seems update process holding exclusive lock on entire table
it is not allowing any furthur update to that table
Could you please tell me what could be the problem for that
Thanks,
- AK

Does the table has primary key - foreign key relationship? Try disabling the constraint and see if it works. If it works then it is about unindexed foreign key issue.

Monitor exclusive lock on a table and send notification email through EM

Hi,
I have Oracle10g and EM10G running on different servers.
now one of my plsql code creates an exclusive lock on one of my tables.
i want to monitor this exclusive lock on this table through the EM. and when the exclusive lock on the table is continuing for more than 1 hour, i want an email notification sent to me by the EM.
How can i do this?
Can someone help me achieve this above situation.
Thanks.
Philip.

One of the nice about OEM is that a lot of the things are self explanatory. E.g. I never read docs to set up our first user defined metrics. It is really just to dive in there. Define a metric and the sql you want to use for monitoring the lock. Then you just go and create email notification for this when it hits warning or critical treshold.
