Anjo,
To simulate the ORA-1554, I tried the following, which I think, is along
the same lines you mention :
1. Created a database with block size 2K.
2. Created one rollback segment in the tablespace RBS.
3. Started 21 session all updating different tables, and not commiting.
4. v$rollstat at this point showed me xacts = 21 and status = ONLINE
5. Started the 22 session and tried an update statement.
6. Oracle reported the "Unable to use system rollback segment for non
system ..." error.
The reason I am trying to simulate this error, is that the application logs
reported the error:
ORA-1595: error freeing extent (3) of rollback segment (2). #### Yes,
optsize is set.
ORA-1554: Out of transaction slots in transaction tables.
I am trying to investigate why? Metalink could not give me a definite
answer, and soft closed the tar.
Thanks
Raj

Please

Rajesh,
Your database has probably only the system rollback segment. Oracle will
probably leave a slot open so in that rollback segment. Create an
additional rollback segment and you will probably see the error.
