I will be upgrading our database and application server from 8.0.5.2.1 and 11.0.2 to Oracle 8.1.6 and Applications 11.5.3.

I understand from reading the upgrade manuals as well as confirming from Oracle support that the database must have a db_block_size of 8k or larger. We are currently setup with a 2k block size which means that we must re-build the database with an 8k or larger block size and the only why of doing that is via exp/imp.

Can anyone share their experience with exporting and importing a large database with thousands of objects? We have about 35k objects in the database and a concern of mine is all the invalid objects that could appear after the import. Are there some key areas I can look at to help reduce the time to import as well as limiting the number of invalid objects?

thanks in advance...roy
