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 upgrades or patches. They are located in the
$ORACLE_HOME/rdbms/admin directory and provide a wrapper on the UTL_RECOMP
package. 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.
