Recompile inavlid objects using UTL_RECOMP

The UTL_RECOMP package contains two procedures used to recompile invalid objects. As the names suggest, the RECOMP_SERIAL procedure recompiles all the invalid objects one at a time, while the RECOMP_PARALLEL procedure performs the same task in parallel using the specified number of threads. Their definitions are listed below:

PROCEDURE RECOMP_SERIAL(
schema IN VARCHAR2 DEFAULT NULL,
flags IN PLS_INTEGER DEFAULT 0);

PROCEDURE RECOMP_PARALLEL(
threads IN PLS_INTEGER DEFAULT NULL,
schema IN VARCHAR2 DEFAULT NULL,
flags IN PLS_INTEGER DEFAULT 0);

-- Schema level.
EXEC UTL_RECOMP.recomp_serial('APPS');
EXEC UTL_RECOMP.recomp_parallel(4, 'APPS');

-- Database level.
EXEC UTL_RECOMP.recomp_serial();
EXEC UTL_RECOMP.recomp_parallel(4);

-- Using job_queue_processes value.
EXEC UTL_RECOMP.recomp_parallel();
EXEC UTL_RECOMP.recomp_parallel(NULL, 'APPS');
