How to enable OLAP in an Oracle 11gR2 database

First, check that the prerequisites are fulfilled. The components below must be installed and valid before proceeding.

select comp_id,  comp_name, version,status from dba_registry where comp_id in ('XDB','XML','JAVAVM','EXF');

COMP_ID    COMP_NAME                      VERSION    STATUS
---------- ------------------------------ ---------- ----------
XDB        Oracle XML Database            11.2.0.4.0 VALID
EXF        Oracle Expression Filter       11.2.0.4.0 VALID
JAVAVM     JServer JAVA Virtual Machine   11.2.0.4.0 VALID
XML        Oracle XDK                     11.2.0.4.0 VALID

If java virtual machine is not installed:

sqlplus / as sysdba
set echo on
spool JServer.log
@?/javavm/install/initjvm.sql;
@?/xdk/admin/initxml.sql;
@?/xdk/admin/xmlja.sql;
@?/rdbms/admin/catjava.sql;
spool off

If XML DB is not yet install, you need to follow "Master Note for Oracle XML Database (XDB) Install / Deinstall (Doc ID 1292089.1)" from Oracle Support


If Oracle Expression Filter is not installed:

sqlplus / as sysdba
@?/rdbms/admin/catexf.sql

1. Start by shutting down the database:

sqlplus / as sysdba
shutdown immediate

2. Prepare your ORACLE_HOME by relinking the "oracle" executable.

For Oracle 11R2 and above, use the chopt utility. It was provided to help DBAs add new options and implicitly relink the binaries.

chopt enable olap

Writing to /u01/oracle/product/11204/install/enable_olap.log...
/usr/bin/make -f /u01/oracle/product/11204/rdbms/lib/ins_rdbms.mk olap_on ORACLE_HOME=/u01/oracle/product/11204
/usr/bin/make -f /u01/oracle/product/11204/rdbms/lib/ins_rdbms.mk ioracle ORACLE_HOME=/u01/oracle/product/11204

For versions prior to 11gR2:

cd $ORACLE_HOME/rdbms/lib
  make -f ins_rdbms.mk olap_on
  make -f ins_rdbms.mk ioracle

3. Open your database:

sqlplus / as sysdba
startup

4. Set up OLAP

cd $ORACLE_HOME/olap/admin
sqlplus / as sysdba
spool install_olap.log
@olap.sql SYSAUX TEMP

5. Verify that OLAP was installed:

select * from v$option where parameter='OLAP';

PARAMETER                      VALUE
------------------------------ ------------------------------
OLAP                           TRUE
