Well, I finally found a good reason for studying for OCP! I would not have known this answer without being forced to study.

It depends on your Oracle version. The Oracle 8i answer is: On startup, Oracle performs recovery, including rolling forward all transactions. Oracle then opens the database for production use. In the background, SMON continues to roll back transactions that were not committed when the database shut down. If a process needs a block that was involved in an uncommitted transaction, then SMON goes ahead and rolls back that transaction so the process doesn't have to wait.

Hi list

stupid one: In case of a shutdown abort and startup, are the rollback activities discontinued after startup and the rollback segs are available again ? or not ?

regards,
Stefan
