how Can I do to change SESSION_CACHED_CURSORS for all sessions?
I found on google and oracle website:
Alter Session...
but I need to changed it for all the session and not only for one of them.
How can I do it?
UPDATE 1:
SQL> alter session set session_cached_cursors=800 scope=both sid='*';
alter session set session_cached_cursors=800 scope=both sid='*'
*
ERROR at line 1:
ORA-02248: invalid option for ALTER SESSION

The ALTER SYSTEM SET clause for this parameter is only valid with the SCOPE=SPFILE option, so you can not change the parameter value with this dynamically.
You can change the value for all other sessions, e.g as below:
This however will not have any effect on the sessions opened after this point. For that, you have to use ALTER SYSTEM as above and restart the database.
