    Hi Friends,
    Some days I get the following errors in my alert log:
    FULL status of rollback segment 20 set.
    failure to extend rollback segment 20 because of 1237 condition.
    failure to extend rollback segment 20 because of 1562 condition.

    After about 2 hours, I get the message saying that FULL status of rollback segment 20 is cleared and from then on there are no more messages .

    My database is having two instances(OPS) and I have 6 rbs for each instance.Their sizing details are:
    INITIAL 80M NEXT 80M MINEXTENTS 2 OPTIMAL 160M

    How can I avoid the 1562/1237 errors? And how can I clear the FULL status myself instead of letting Oracle do in its own time?
    All help is appreciated.
    Thanks

    Looks like that you are ending up in an open transaction, where the user is not doing the commit. Take a look into this metalink note on how to fix this problem
