Comment on Performance Degradation for Query on DBA_SEGMENTS.BYTES in 11gR2 by Ronny Egner

Ronny Egner — Tue, 23 Aug 2011 13:12:17 +0000

What i have here right now is a system which is affected. The reson is totally unclear to me.
The system here is on 11.2.0.2.0 + BP6 (Exadata Bundle Patch).

Hi Ronny,

Oracle Support wants me to deliver a testcase in order to investigate what was the root cause for the problem. The mentioned workaround comes from a known issue with former releasess so it is currently unclear why 11gR2 (PSU April 2011) is still affected. However, I´m not sure whether we will have time and resources for the testcase.

Regards,
Martin

Hi Martin,

i observed the same in a 11.2.0.2.0 X2-8 exadata. Also a big DWH (> 10 TB).

I will try your fix and let you know.

Similar issue (though should have been fixed in 11.2 and your patchlevel is the most actual) – index creation in parallel by impdp ?

Comment on Recyclebin Bug – ORA-600 [ktcdso-1] on Oracle 11.2.0.2.1 by admin

admin — Tue, 26 Apr 2011 15:37:43 +0000

Hello Chandra,

unfortunately, alter system set recyclebin is static and needs an instance restart:

SQL> alter system set recyclebin=OFF;
alter system set recyclebin=OFF
*
ERROR at line 1:
ORA-02096: specified initialization parameter is not modifiable with this
option

In our case, it was necessary to restart the instance to get rid of the ORA-600 Errors.

Best regards,
Martin

Comment on Recyclebin Bug – ORA-600 [ktcdso-1] on Oracle 11.2.0.2.1 by Chandra Pabba

Hi Martin,

Quick comment – the init.ora parameter RECYCLEBIN can be set to OFF with ALTER SYSTEM command – therefore, no need to bounce the database to de-activate recyclebin.

Thanks
Chandra

Thank you so much for this, I asked this on the Oracle forums but never got an answer, then stumbled on this post while looking at your latest child cursors post.

I just find it hilarious when monitoring software is just plain wrong, and even more so when it significantly impacts performance.
