DOC>   The following PL/SQL block invokes UTL_RECOMP to recompile invalid

DOC>   objects in the database. Recompilation time is proportional to the

DOC>   number of invalid objects in the database, so this command may take

DOC>   a long time to execute on a database with a large number of invalid

DOC>   objects.

DOC>

DOC>   Use the following queries to track recompilation progress:

DOC>

DOC>   1. Query returning the number of invalid objects remaining. This

DOC>      number should decrease with time.

DOC>         SELECT COUNT(*) FROM obj$ WHERE status IN (4, 5, 6);

DOC>

DOC>   2. Query returning the number of objects compiled so far. This number

DOC>      should increase with time.

DOC>         SELECT COUNT(*) FROM UTL_RECOMP_COMPILED;

DOC>

DOC>   This script automatically chooses serial or parallel recompilation

DOC>   based on the number of CPUs available (parameter cpu_count) multiplied

DOC>   by the number of threads per CPU (parameter parallel_threads_per_cpu).

DOC>   On RAC, this number is added across all RAC nodes.

DOC>

DOC>   UTL_RECOMP uses DBMS_SCHEDULER to create jobs for parallel

DOC>   recompilation. Jobs are created without instance affinity so that they

DOC>   can migrate across RAC nodes. Use the following queries to verify

DOC>   whether UTL_RECOMP jobs are being created and run correctly:

DOC>

DOC>   1. Query showing jobs created by UTL_RECOMP

DOC>         SELECT job_name FROM dba_scheduler_jobs

DOC>            WHERE job_name like 'UTL_RECOMP_SLAVE_%';

DOC>

DOC>   2. Query showing UTL_RECOMP jobs that are running

DOC>         SELECT job_name FROM dba_scheduler_running_jobs

DOC>            WHERE job_name like 'UTL_RECOMP_SLAVE_%';
