"Delete" or "rollback" is not clear enough. Insert;commit;delete?
insert;rollback? Or Insert; session killed; smon rollback?
If its rollback, then Shutdown abort, Startup :)
Since it's a testing environment, and if brave enough, you could maybe test
with:
Shutdown abort
/FAST_START_PARALLEL_ROLLBACK=high/_cleanup_rollback_entries=400/ startup

We have ORACLE 10GR2 on Linux servers. Users are using ORACLE ODI tool to
perform testing. Those testing will insert 20 to 30 millions records to tables
then it will 'delete" or "rollback" data. Users complain "delete" or
"rollback" 20 to 30 millions records take long time to finish.
Does there has way to improve "delete" or "rollback" performance by setup DB
parameters like SGA, PGA, ...?
Thanks.
