How to rebuild datapump metadata? (if corrupted)

How to rebuild datapump metadata? (if corrupted)

Some times, due to some internal errors, datapump utility binaries may get corrupted. In such cases, we can rebuild that using below ways

In Oracle database 10.1 version :

SQL> connect / as sysdba

SQL >@ $ORACLE_HOME/rdbms/admin/catdp.sql – this will install metadata

SQL >@ $ORACLE_HOME/rdbms/admin/dbmspump.sql – this will create DBMS procedures for datapump

In Oracle database 10.2 version :

SQL >@ $ORACLE_HOME/rdbms/admin/catdph.sql

SQL >@ $ORACLE_HOME/rdbms/admin/prvtdtde.plb

SQL >@ $ORACLE_HOME/rdbms/admin/catdpb.sql

SQL >@ $ORACLE_HOME/rdbms/admin/dbmspump.sql

After performing above steps, all the binaries will be re-build. So, it is better to execute utlrp.sql to recompile invalid objects

SQL >@ $ORACLE_HOME/rdbms/admin/utlrp.sql

In Oracle 11g :

SQL >@ $ORACLE_HOME/rdbms/admin/catproc.sql (catproc.sql will take care of all other script execution)

To recompile invalid objects, if any

SQL >@ $ORACLE_HOME/rdbms/admin/utlrp.sql

Note: If you encounter this datapump binaries corruption issue on a production database, before executing above steps, it is strongly recommended to first test this and based on results you can implement in production
