Applies to: Oracle Database - Enterprise Edition - Version 10.2.0.1 to 12.1.0.1 [Release 10.2 to 12.1] Other UNIX Goal To show how to install/deinstall and/or disable/enable the following database components at the ORACLE_HOME software/bin

Goal

To show how to install/deinstall and/or disable/enable the following database components at the ORACLE_HOME software/binary level:

This requires advanced skills to make the changes and perform the relink.

This note WILL NOT address product specific scripts that are required at the database level for specific components to further complete the install/deinstall process.

Please refer to the appropriate Oracle Component Guide or as a starting point

Note 472937.1 Information On Installed Database Components and Schemas

Furthermore it will only cover UNIX/LINUX and Windows where applicable covering versions 9.2.0.x through 11.2.0.x.

Solution

Checking if products/components have been installed

Starting with releases 11.1.0.7.x and above all products are installed by default and the option to customize the product/component selection is no longer possible.
The only customization that can be done on these releases is to enable or disable certain products/components which will be covered in the following divs.

For versions 9.2.0.x through 11.1.0.6.x product installation can be confirmed in the following manner:

1. Using the Oracle Universal Installer (OUI) from either the $ORACLE_HOME/oui/bin or software installation media:

$ cd

$ ./runInstaller

click on "Installed Products"
select the ORACLE_HOME
click on "Expand All"
Review the list or products installed.

2. Use the opatch utility:

$ export PATH=$ORACLE_HOME/OPatch:$PATH

$ opatch lsinventory -detail

Review the log file in either $ORACLE_HOME/.patch_storage/ or $ORACLE_HOME/cfgtoollogs/opatch/lsinv

Use the following notes to assist with product identification:

Note 783288.1 Oracle Database Software Component Guide for 10gR2

Note 783290.1 Oracle Database Software Component Guide for 11gR1

What file contains the various status's of products/components?

Once the products/components have been confirmed as being installed (applicable only to versions 9.2.0.x through 11.1.0.6.x) then they can be enabled/disabled at the binary level.

The file that contains the status of components being enabled or disabled is:

$ORACLE_HOME/rdbms/lib/libknlopt.a

The relevant files contained within this archive and status's associated with them are:

Automatic Storage Mgt ON=kfon.o
Automatic Storage Mgt OFF=kfoff.o

Context Management Text ON=kciwcx.o <
Oracle Data Mining ON=dmwdm.o
Oracle Data Mining OFF=dmndm.o

Oracle Database Vault ON=kzvidv.o
Oracle Database Vault OFF=kzvndv.o

Oracle OLAP ON=xsyeolap.o
Oracle OLAP OFF=xsnoolap.o

Oracle Label Security ON= kzlilbac.o
Oracle Label Security OFF= kzlnlbac.o

Oracle Partitioning ON=kkpoban.o
Oracle Partitioning OFF=ksnkkpo.o

Real Application Cluster ON=kcsm.o
Real Application Cluster OFF=ksnkcs.o

Oracle Real Application Testing ON=kecwr.o
Oracle Real Application Testing OFF=kecnr.o

The following command can be used to verify the contents of the archive:

$ cd $ORACLE_HOME/rdbms/lib

$ ar -tv libknlopt.a

For IBM AIX

$ cd $ORACLE_HOME/rdbms/lib

$ ar -X64 -tv libknlopt.a

Checking if products/components have been enabled/disabled at the binary level

An alternative to going through the $ORACLE_HOME/rdbms/lib/libknlopt.a output line by line is to check the archive for the existance of the 'ON' file noted above by running the following command:

$ cd $ORACLE_HOME/rdbms/lib

$ ar -t libknlopt.a | grep -c

For IBM AIX

$ cd $ORACLE_HOME/rdbms/lib

$ ar -X64 -t libknlopt.a | grep -c

Where is:

For example:

$ ar -t libknlopt.a | grep -c kfon.o

For IBM AIX

$ ar -X64 -t libknlopt.a | grep -c kfon.o

If the output is 0, the option is disabled.

If the output is 1, the option is enabled.

How to enable/disable products/components at the binary level

For all versions 9.2.0.x through 11.2.0.x or above products/components can be enabled or disabled by running 'make' commands and passing the appropriate switch.

Note:
All processes running from the ORACLE_HOME including but not limited to databases, listeners, intelligent agents, etc. must be shutdown/stopped before issuing these commands.

For example to enable/disable Oracle Partitioning:

Enable
------
$ cd $ORACLE_HOME/rdbms/lib

$ make -f ins_rdbms.mk part_on ioracle

Disable
-------
$ cd $ORACLE_HOME/rdbms/lib

$ make -f ins_rdbms.mk part_off ioracle

The list of switches for each product/component are:

Warning: switching on ASM should only be done on Grid Infrastructure Homes in Oracle 11gR2. Doing it on an RDBMS ORACLE_HOME will result in errors on startup.

Starting with 11.2 and above there is a utility called 'chopt' that can be used in UNIX/LINUX and WINDOWS as well.

usage:

chopt

For example to enable/disable Oracle Partitioning:

Enable
--------
$ chopt enable partitioning

Disable
---------
$ chopt disable partitioning

This utility only works for the following products/components:

For Oracle Database 12.1 , only the following components can be enabled/disabled:
