Hi DBAs,

I got a problem in Rollback Segments..

This is the setting for UNDO ( Rollback ) in my init file...

undo_management=AUTO
undo_retention=900
undo_suppress_errors=FALSE
undo_tablespace=UNDOTBS

While querying V$waitstat, got the foll. :

CLASS                    COUNT                     TIME
system undo header            0                        0
system undo block              0                        0
undo header                  312                      64
undo block                         1                      32

The entry for "undo header" indicates Undo Header contention for rollback.. Right ?

Since it is "AUTO" managed, how do i tune ??

I have chk  the space usage of the tablespace, it is fairly enough free
space...

Any suggestions / tips ?

Thank You.

regards,
Arul.
