Hi Purav,
you may want to ensure that you don't have too many versions of the same
SQL in the Library Cache. So-called version count issues are the most
common issue when shared pool grows.
A count of entries in v$sql and group by sql_id, is the most simple check.
More insight allows v$sql_shared_cursor
Best regards
Martin
