Hi Experts.

Request is as below.

Source details:TEST,10.2.0.3,Aix 5.3  ( It has 900 application schemas)
Target details:TESTA,11.2.0.2,Aix 5.3  (Target db already exists)


Source database size is around 150GB.

Request is to do the datacopy from Source to target as quick as possible.

Tried below options:

1.Full database backup using expdp of source db and import the backup dump excluding all the oracle default users.

But fulldatabase backup of source database was running very slowly,found that the issue was due the  Bug 6460304  and it
looks like need to upgrade the database to 10.2.0.4 or 11.2.0.3. Currently upgrading the database is not a feasible option now.

Howdy, Stranger!
