dbms_shared_pool.markhot - Hash value

Hi All,

I'm planning to use dbms_shared_pool.markhot to overcome library cache mutex X contention.

exec dbms_shared_pool.markhot('HYCEA','CORE',1);

EXEC DBMS_SHARED_POOL.MARKHOT('HYCEA','CORE',2);

EXEC DBMS_SHARED_POOL.MARKHOT(HASH=>105208,NAMESPACE=>1);

i need clarifications regarding the HASH=>105208,NAMESPACE=>1

How to obtain the HASH value (105208) & namespace value (1) for a particular package & package body.
