utlrp.sql

PL/SQL

SYS

Recompiles all existing PL/SQL modules that were previously in an INVALID state, such as packages, procedures, and types.

Run the

utlrp.sql

script after creating or upgrading a database. This script recompiles all PL/SQL modules that may be in an INVALID state, including
packages, procedures, types, and so on. This step is optional, but recommended so that the performance cost of recompilation is incurred during the installation rather than in the future.

Note:

There should be no other data definition language (DDL) statements running on the database while the script is running, and packages

STANDARD

and

DBMS_STANDARD

must be valid.

Start SQL*Plus:

DRIVE_LETTER:\> sqlplus /nolog

Connect to the database with the

SYS

account:

SQL> CONNECT SYS AS SYSDBA
Enter password:
SYS_password

Start the database (if necessary):

SQL> STARTUP

Run the

utlrp.sql

script, which by default is located in

ORACLE_HOME

\rdbms\admin\utlrp.sql

. For example:

SQL> @?\rdbms\admin\utlrp.sql
