URGENT - Can you coalesce a RBS tablespace?

URGENT - Can you coalesce a RBS tablespace?

Apologies - Here's are the error messages I was receiving -

ORA-01562 (See ORA-01562.ora-code.com) Failed to extend rollback segment number 11
ORA-01650 (See ORA-01650.ora-code.com) unable to extend rollback segment RBS10 by 128 in tablespace RBS.

It started with one user at first and then started to spread to a number of
users on the same instance.

The weird thing about it was the initial extent of segment 10 was 128.  The
next size was 1M with the optimal size being 5M.

It appeared that it was even having troubles with the initial extent.  I guess
that is why I labeled it 'urgent'.  I wasn't sure why it couldn't even create
the initial extent.  The free space still does not appear to be giving itself
back to the instance....


Thanks for asking for the follow-up - I want to make sure that I too,
contribute to this forum.

Jeff

Glad to see your problems have abated somewhat.

Many of us would still like to know what indications you
saw (error message?) that identified rollback segments
as the source of the problem.
