dear Orafaq,
need your help... last week we have just migrated our database to O8i(8.1.6). however, during the trial-run, we found the response time of the database to be slow.
one major factor that were looking@the moment is the initial settings of the database (mostly the size of the data blocks).
does anyone know how to resize the initial db_blk_size in the control files??..

thanks,

you cannot change block size, once the database is created.
so,
change the block size in initora.
and recreate the database.

dear mahesh,
once again, thank you for your reply!!.. we already change the db_block_size parameter in initora, but it caused us the incompatibility error with the control files.
i understand your point about re-creating the database to re-define the control files,.. but - is there no other work around to this problem? our company is currently on a 24/7 production status that's why it will be very difficult for us to create a new database.
thanks for your help!

brgds,

May be you did not get what Mahesh said...

recreate the database means create from scratch...

Good luck.
