SQL performance degradation after database migration and upgrade

edited Aug 10, 2020 12:58PM in SQL Performance (MOSC) 2 commentsAnswered

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.

Howdy, Stranger!
