eventhough the db is big around 1 TB, all datafiles are in single mountpoint.
but i am really looking to start debugging (dont knwo if oradebug or someother utility will help what is happening after mount and before open).

how about checking the datafiles placements. probably it will be a good way to start debugging is by starting with making datafiles offline for some non-system tablespaces and see if it helps.

One of our test instances, the startup process is taking more time.
sga is ~2gb.

especially, the open phase takes long time.(around 10 mins)
instance allocation and mount phase are quick.
Can someone help me, how to start research and reduce the time.
Thanks,
