How to run UTL_RECOMP.RECOMP_PARALLEL from a procedure? - oracle

Question

I have a simple question: Is it possible to run UTL_RECOMP.RECOMP_PARALLEL from a procedure?
I have a Package with a procedure which should recompile all invalid objects. It looks like this:
PROCEDURE Compile ()
IS
BEGIN
EXECUTE IMMEDIATE ('BEGIN SYS.UTL_RECOMP.RECOMP_PARALLEL(4,); END;');
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.PUT_LINE(SQLERRM);
END;
However, I always get the Error PLS-00201: identifier 'UTL_RECOMP.RECOMP_PARALLEL' must be declared
I am logged in as sys/sysdba user. That's not the problem.
Any ideas how to get this working?
Thanks!

Actually it works if the procedure is owned by SYS and you grant EXECUTE privilege to another user (doc says "You must be connected AS SYSDBA to run this script").

These kind of procedures should be run only by SYS (like utlrp.sql) - so this is for DBA only - as documented to avoid unexpected behaviour.

You can use it in a stored procedure:
SQL> set serveroutput on
SQL> --
SQL> select banner from v$version;
BANNER

2 IS
3 BEGIN
4 UTL_RECOMP.RECOMP_PARALLEL(4);
5 EXCEPTION
6 WHEN OTHERS
7 THEN
8 DBMS_OUTPUT.PUT_LINE(SQLERRM);
9 END;
10 /
Procedure created.
SQL> --

No errors.
SQL> --
SQL> set timing on
SQL> exec compile;
