Home -> Community -> Mailing Lists -> Oracle-L -> RE: RBS problem...
You can find many notes about rollback segments in Metalink.
Note:62005.1 says that :
"The system rollback segment can only be used for transactions that occur on
objects inside the system tablespace. This is done because the main purpose of
the system rollback segment is to handle rollback for DDL transactions - that
is transactions against the data dictionary tables themselves. "
Your script uses one of the other online rollback segments. You can find which one is being used by querying v$transaction.
hi all,
Thanx for the reply and help. But my question is I have a script wherein I am specifying a particular RBS to be used and before the execution of the script the RBS is dropped. No doubt I will get the error saying that the specified rollback segment does not exist( which I received this morning) and the rest of the command were executed successfully. Which RBS was used for the transaction(was it SYSTEM) how to check this. My colleague says it wont use SYSTEM in any condition but other RBS will be used. Is it true? Why SYSTEM rbs can not be used in any situation if he is right. and in what conditions this SYSTEM rbs is used?

Hi Onkar,
When you assigned a particular rollback segment to the transaction which is actually deleted, Oracle will use the default rollback segment.
To assign a rollback segment to a particular transation use either:-
DBMS_TRANSACTION.USE_ROLLBACK_SEGMENT(NAME)
OR
DBMS_STANDARD.SET_ROLL_SEGS(NAME)
