First of all, why can't the user application use system_2 rollback segment? The only rollback segment they won't use is the SYSTEM rollback segment.

We have ORACLE 8.1.6 on SUN Solaris 2.7 server. Recently I check
"alert.log" file and found following error message:

ORA-1628: max # extents 121 reached for rollback segment SYSTEM_2 Failure to extend rollback segment 10 because of 1628 condition FULL status of rollback segment 10 set.A

We have seperate Rollback tablespace for users to run application. The following is our rollback configuration:

NAME OPTIMAL_KB SIZE_KB HI_WATER_KB EXTENDS ---------- ---------- ---------- ----------- ----------

ROLLBACK_1       5120       5312        5312          0
ROLLBACK_2       5120       5312        5312          0
ROLLBACK_3       5120       5312        5312          0
ROLLBACK_4       5120       5312        5312          0
ROLLBACK_5       5120       5312        5312          0
ROLLBACK_6       5120       5312        5312          0
ROLLBACK_7       5120       5312        5312          0
ROLLBACK_8       5120       5312        5312          0
SYSTEM                       568         568          0
SYSTEM_2                    7736        7736          0

This is first time on four years this database got this kind of error message. Can anyone tell me why user application will use
"system_2" rollback segment?

Thanks.
