SQL> Rem utlprp.sql - Recompile invalid objects in the database
SQL> Rem
SQL> Rem DESCRIPTION
SQL> Rem This script recompiles invalid objects in the database.
SQL> Rem
SQL> Rem This script is typically used to recompile invalid objects
SQL> Rem remaining at the end of a database upgrade or downgrade.
SQL> Rem
SQL> Rem Although invalid objects are automatically recompiled on demand,
SQL> Rem running this script ahead of time will reduce or eliminate
SQL> Rem latencies due to automatic recompilation.
SQL> Rem
SQL> Rem This script is a wrapper based on the UTL_RECOMP package.
SQL> Rem UTL_RECOMP provides a more general recompilation interface,
SQL> Rem including options to recompile objects in a single schema. Please
SQL> Rem see the documentation for package UTL_RECOMP for more details.
SQL> Rem
SQL> Rem INPUTS
SQL> Rem The degree of parallelism for recompilation can be controlled by
SQL> Rem providing a parameter to this script. If this parameter is 0 or
SQL> Rem NULL, UTL_RECOMP will automatically determine the appropriate
SQL> Rem level of parallelism based on Oracle parameters cpu_count and
SQL> Rem parallel_threads_per_cpu. If the parameter is 1, sequential
SQL> Rem recompilation is used. Please see the documentation for package
SQL> Rem UTL_RECOMP for more details.

SQL> Rem NOTES
SQL> Rem * You must be connected AS SYSDBA to run this script.
SQL> Rem * There should be no other DDL on the database while running the
SQL> Rem script. Not following this recommendation may lead to deadlocks.

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

DOC>
DOC> Use the following queries to track recompilation progress:

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