Privilege on EXECUTE package

Question

i've done "GRANT EXECUTE ANY PROCEDURE ON USER1", user1 still couldn't execute the package he created SCHEMA1.package1
i want to grant system privilege so that he can run packages under user defined schema. i don't want to grant execute privilege on package1 only.
any suggestion?

Answer 1

You were able to create package in the school schema using login user1 because user1 will have create any procedure privilege.
I am assuming you are executing package with schools login,
So here it is how it works.
The creator of the object(package/procedure/function) is called DEFINER.
The user who calls the object or execute the object is called INVOKER.
There are Definer and Invoker Rights for stored routines in Oracle.By defalut any objects created takes DEFINER rights
(Example
table APPPARMST belongs to schema A. User A creates a procedure UPDATE_PAR allowing for updates of a table. User B is granted execute privileges on the procedure. Now user B cannot access the table as no privileges have been granted, but can call the procedure to do the required process logic for updating the table.
whenver User B excutes the procedure UPDATE_PAR it will run taking User A(Invoker's rights) since User A can read table
APPPARMST so the procedure gets executed.
In your case the package is owned by schema user1 which is definer as well.USER1 will not have select privilege on table under GEO schema thats the reason Schools user can't execute the package.
you will have to run this login with geo user
grant select on <tablename> to user1;
it should solve the issue..
Hope I am able to answer all your questions..
