To activate the RCVmanager, go to the Database Window and type “start rcvmanager”. Then issue the “list rollback tables” command. It will show you each table that is being rolled back at that point in time, how many TJ rows have been rolled back and how many rows are remaining.

If you run this command twice, you can then make an estimate how long it will take the rollback to complete, based on the rows processed and rows remaining and the time between the two snapshots.

list rollback tables;
