Hi Experts,
I want to change cursor_sharing=FORCE in my session level, I dont want to use 'alter session set cursor_sharing=FORCE'. Is there any alternate for that something like dbms_system.set_int_param_in_session ?

I suggest delete with refund.

stored outlines aren't really equivalent to cursor sharing.

while not at all equivalent, stored outlines can be complimented by cursor sharing

they apply to specific queries so two queries with different literals would not be recognized for the purposes of outlines.

cursor sharing would allow more queries to use a given outline because the literals would be replaced with binds, allowing them to match an outlined query with binds.


However, to answer the virdi_ds's  question...

the boolean equivalent for dbms_system is...


  dbms_system.set_bool_param_in_session(:sid, :serial, 'cursor_sharing', TRUE);


Note, dbms_system has no permissions by default and is undocumented/unsupported by Oracle.

Now that I've posted an answer, I rescind my suggestion of delete with refund.  :)

Hopefully my suggestion will be found acceptable.
