Comment on How can I check if there is anything rolling back? by famegaurav

famegaurav — Fri, 15 Oct 2010 04:35:24 +0000

To check for rollback:
##########################################################################

select used_ublk from v$transaction where ADDR=;

If there is a value there, this is the number of undo blocks used by the
transaction. Wait one minute and again select “used_ublk” from
“v$transaction” where ADDR=; .

Note the value. If it is decreasing, a rollback is occuring and based on the
difference between these values, you can “guesstimate” the time required to
complete the rollback. For example, if the first query returns a value of
80000 and the second one returns 70000, it took 1 minute to rollback 10000
blocks. Based on this number, you can guestimate the time to complete the
rollback. In this case, it would be 7 minutes.

Do these two tables need to be done together (are they related somehow) or can they be done separately?
