SQL performance degradation after database migration and upgrade
We are migrating oracle database to another server.It also contains version upgrade from 11g to 12c .
I am wondering , would there be a hard parsing and new plans generation for all the SQLs executing for first time in the target database after migration ? If yes, is there any way to avoid it?
We are migrating only non-default schemas and tablespaces with datapump.
Any suggestion would be highly appreciated. Thanks in advance.
