Is it possible to rollback another user's last uncommited transaction. It has blocked other sessions. I only know the sid and serial# of blocking session. I dont want to kill this session as it will impact the apllication and would require application restart. For the time being, I am able to live with this. But soon the issues will crop up. It's kind of urgent requirement. I googled and found some rollback work force '25.32.87' but couldn't find its meaning. How will I use it to rollback the transaction of session I am wiling to rollback? Also dba_2pc_pending has no rows.

dba_blockers shows one row as discussed above. dba_waiters has 2 rows.
