utlrp.sql and utlprp.sql-优快云博客

本文介绍Oracle提供的utlrp.sql及utlprp.sql脚本，用于数据库中所有无效对象的重构。这些脚本通常在重大数据库变更如升级或打补丁后运行，并依赖于UTL_RECOMP包。文章详细解释了不同参数对并行重构的影响。

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.
