    Hi,
    For cache of table : does it need to be specified at CREATE TABLE stage only. Also does cache mean it will stay in memory forever (like PIn/KEEP of PL/SQL in shared Pool) or is there a case when it will get aged out. Thanks for your help. Yes. there is an option with : ALTER TABLE xxxx CACHE. However below is what documentation says :    

  CACHE | NOCACHE Use the CACHE clauses to indicate how Oracle should store blocks in the buffer cache. If you specify neither CACHE nor NOCACHE:     

   In a CREATE TABLE statement, NOCACHE is the default    In an ALTER TABLE statement, the existing value is not changed.
