The utlrp.sql and utlprp.sql scripts are provided by Oracle to recompile all invalid objects in the database.
They are typically run after major database changes such as upgrade or downgrade or patches installation.
They are located in the $ORACLE_HOME/rdbms/admin directory and provide a wrapper for the UTL_RECOMP package. UTL_RECOMP provides a more general recompilation interface, including options to recompile objects in a single schema. Please see the documentation for package UTL_RECOMP for more details.
The utlrp.sql script simply calls the utlprp.sql script with a command line parameter of "0".
The utlprp.sql accepts a single integer parameter that indicates the level of parallelism as follows.
0 - The level of parallelism is derived based on the CPU_COUNT parameter.
1 - The recompilation is run serially, one object at a time.
N - The recompilation is run in parallel with "N" number of threads.
Both scripts must be run as the SYS user, or another user with SYSDBA, to work correctly.
Thank you for the reading and support.
