Sample Configurations with SGeRAC and Oracle RAC 10gR2, March 2009

Configuring ODM

ODM is required when using Oracle RAC with SGeRAC and CFS. For this sample configuration, the

ODM libraries are included with the HP Serviceguard Storage Management Suite bundle for RAC.

Previously, there was a confirmed problem with creating an Oracle database with dbca after

enabling ODM (linking the ODM library). The Oracle bug # is 5103839. The workaround was to

create the database (see §4.2.8) first and then link ODM (§4.2.7). Starting with Oracle 10.2.0.3,

this problem has been resolved and the workaround is not needed.

Check ODM availability

1. Check the VRTSdbed license.

# /opt/VRTS/bin/vxlictest -n “VERITAS Storage Foundation for Oracle” -

f “ODM”

ODM feature is licensed

2. Check that the VRTSodm package is installed.

# swlist VRTSodm

VRTSodm 5.0.01.01 Veritas Oracle Disk Manager

VRTSodm.ODM-KRN 5.0.01.01 Veritas ODM kernel files

VRTSodm.ODM-MAN 5.0.01.01 Veritas ODM manual pages

VRTSodm.ODM-RUN 5.0.01.01 Veritas ODM commands

3. Check that libodm.sl is present.

# ls -lL /opt/VRTSodm/lib/libodm.sl

-r-xr-xr-x 1 root sys 81464 May 15 2006 /opt/VRTSodm/lib/libodm.sl

Configure Oracle to use ODM library

1. Login as Oracle user

2. Shutdown database (if running)

3. Link the Oracle Disk Manager library into Oracle home for Oracle 10g

For HP 9000 systems:

$ rm ${ORACLE_HOME}/lib/libodm10.sl

$ ln -s /opt/VRTSodm/lib/libodm.sl ${ORACLE_HOME}/lib/libodm10.sl

For HP Integrity systems:

$ rm ${ORACLE_HOME}/lib/libodm10.so

$ ln -s /opt/VRTSodm/lib/libodm.sl ${ORACLE_HOME}/lib/libodm10.so

Configure Oracle to stop using ODM library

1. Login as Oracle user

2. Shutdown database (if running)

3. Link the original Oracle Disk Manager library into Oracle home for Oracle 10g

Note:

Some versions of the SGeRAC manual incorrectly removed the installed

library (“libodmd10.sl”for HP 9000 systems and “libdodmd10.so”

for HP Integrity systems). The correct behavior is to remove the link.
