Symptoms
 When running expdp the following errors are raised:

ORA-39006: internal error
ORA-39213: Metadata processing is not available

This error was detected while executing the DataPump in any platform.
 
Cause
 DataPump export uses DBMS_METADATA_UTIL package but this package does not successfully ran.  
Executing sys.dbms_metadata_util.load_stylesheets procedure failed with following error:

 
ORA-31609: error loading file "kualter.xsl" from file system directory "/rdbms/xml/xsl"
ORA-06512: at "SYS.DBMS_METADATA_UTIL", line 1807
ORA-06512: at line 1


This package needs XML being installed and XML needs JAVA being installed.

The select from view dba_registry shows neither Java nor XML were installed:


SQL> SELECT comp_id, version, status FROM dba_registry;  

COMP_ID                      VERSION                     STATUS
---------------------------  --------------------------- -----------
CATALOG                      10.2.0.2.0                  VALID
CATPROC                      10.2.0.2.0                  VALID

 
Solution
 1. Install JVM and XML  executing the following scripts from sqlplus:


SQL> connect / as sysdba
SQL> @$ORACLE_HOME/javavm/install/initjvm.sql
 
SQL> connect / as sysdba
SQL> @$ORACLE_HOME/xdk/admin/initxml.sql
 
SQL> connect / as sysdba
SQL> @$ORACLE_HOME/rdbms/admin/catjava.sql
 
SQL> connect / as sysdba
SQL> @$ORACLE_HOME/rdbms/admin/utlrp.sql
 
2. Check if the scripts successfully ran:

select comp_name, version, status from dba_registry;

 COMP_NAME                          VERSION                     STATUS
---------------------------------- --------------------------- -------

Oracle Database Java Packages      10.2.0.2.0                  VALID

3. Run again sys.dbms_metadata_util.load_stylesheets from sqlplus:

connect / as sysdba
execute sys.dbms_metadata_util.load_stylesheets;
