ROLLBACK SEGMENTS OPERATION

Advertisement
November 30

Hello Everyone
This is the first time I am a forum member and I'm figuring out how it works because I have a very big problem
Look, I'm a support engineer and, as you know, the code of the application is not own by me.
Three weeks ago I received a report which is related with the Rollback operation.
There's a process which delete old data from my database and, normally, this process has three parts, as shown in the alert_dbinstance.log:
Wed May 17 03:00:08 2000
alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE
Wed May 17 03:00:08 2000
Completed: alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE
Wed May 17 04:52:25 2000
alter ROLLBACK SEGMENT CLEANUP_RS0 SHRINK
Wed May 17 04:52:26 2000
Completed: alter ROLLBACK SEGMENT CLEANUP_RS0 SHRINK
Wed May 17 04:52:26 2000
alter ROLLBACK SEGMENT CLEANUP_RS0 OFFLINE
Completed: alter ROLLBACK SEGMENT CLEANUP_RS0 OFFLINE
But, one day, the server crashed and this process didn't finish:
Sat May 20 03:00:03 2000
alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE
Sat May 20 03:00:03 2000
Completed: alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE
Sat May 20 04:39:09 2000
the next messages about this process are these:

Since this day, the delete process sends this message:
--- Fault (4) Notify (3) : 2000-06-01 03:00:01 ---
Message (400020): Database Operation Failed
Partition: 0
Module (13000): Daily Cleanup
Description: ORA-00955: name is already used by an existing object
My question here is : Is there a way, using oracle, to identify this object? Can I find the objects with a failure register in a table? in a log file?
thanks for your comments and your efforts. I'll be very thankful.

It seems you should look here:
ORA-1636 signalled during: alter ROLLBACK SEGMENT CLEANUP_RS0 ONLINE...
Looks like you have ORA-01636 error:
rollback segment 'string' is already online
I suggest you check Oracle documentation about this error. Seems to me your process try to access rollback segment that is already in use.
