Hi, guys
We have Oracle 10g(10.2.0.4) RAC on AIX 5.3, there are 3 RAC instances on each node.

From Oct 9th, we found one of the instance in node 1 generated a large size trace files in udump. The largest size of the trace file take up 3G. But there's only about 15G $ORACLE_BASE direcotry. After some time, we should delete some trace files for releasing the space.

Here is a part of alert log when this issue happen:

ORA-00600/ORA-07445/ORA-03113 = Oracle bug => search on Metalink and/or call Oracle support
Have a look at alert.log and trace files.
You can also read this article: Troubleshooting Internal Errors.

Hi, Michel
Thanks for reply.
I have lookup those ora-600 errors on Metalink. But they don't say anything that those errors will generated such huge trace files, So I am not sure if this issue cause by ora-600.
Most of those files generated systemdump info.

Thanks very much,
Milo

Hi, Michel
I don't set any event in the instance. And ask the developers, they said they don't set any events neither.

Thanks,

Check again in alert.log, a system state dump can occur only on ORA-600, ORA-7445 and a couple of other errors or when it is requested by an event. As yours are not related to an error, then it should be related to an event.

If you find any then you have to open a SR.

Hi, Michel
Do you have any method to check if those events have been triggered?
I want to double check and make sure this.

Thanks very much,

Connect as sysdba and execute:
oradebug setmypid
oradebug dump events 4

Post the generated trace file; it contains just after the header (that ends with "*** SESSION ID") a line "Dump event group for level SYSTEM".

Hi, Michel
I have tried this on my test environment, but it seems that there is no differences before I swtich on and after I switch on the event.

alter session set events 'immediate trace name SYSTEMSTATE level 10';



Here is what I am trying in my enviroment:
SYS@myrac2>oradebug setmypid
Statement processed.
SYS@myrac2>
SYS@myrac2>oradebug dump events 4 
Statement processed.
SYS@myrac2>alter session set events 'immediate trace name SYSTEMSTATE level 10';

Session altered.

SYS@myrac2>oradebug setmypid
Statement processed.

Here is what I can see from the trace file:
*** 2011-10-24 18:08:57.608
Dump event group for level SYSTEM
TC Addr  Evt#(b10)   Action   TR Addr    Arm    Life
*** 2011-10-24 18:09:21.813
Dump event group for level SYSTEM
TC Addr  Evt#(b10)   Action   TR Addr    Arm    Life


Is there something I am missingļ¼Ÿ

Thanks very much,
Milo

"immediate trace" events are not recorded as they are a ONE TIME immediate trace.

Session altered.

You set a SESSION event, you dump SYSTEM event.

Hi, all
After asked the support engineer, they said this may cause by a bug. They're not 100% sure about this. Because some similar issues have fixed in 10.2.0.4.
A patch will need to apply and if this patch can't solve the problem, then database should upgrade to the latest version.
If this issue still exists in the latest version, then it should be report as a new bug, otherwise this can't be raise a bug as 10.2.0.4 has higher release.
Hope someone who met similar issue can get some info from this.

Thanks very much.
Milo
