Sample Configuration with HP Serviceguard Extension for RAG and Oracle Real Application Clusters 11g release 2 using Cluster File System

Create Oracle Cluster Software home directory

For installing Oracle Cluster Software on a local file system, create the directories on each node.

# mkdir –p /u01/app/11.2.0/crs

# chown –R oracle:oinstall /u01/app/11.2.0/crs

# chmod -R 775 /u01/app/11.2.0

The Oracle Cluster Software home directory is as follows:

/u01/app/11.2.0/crs/

When installing Oracle Cluster Software, you should set the ORACLE_HOME environment to specify this

directory. Please note, at installation, and before running the

root.sh script, the parent directories of

the Oracle Cluster Software home directory should be changed to permit only the

root user to write

to those directories.

Create Oracle base directory (for Oracle RAC DBMS binaries on Cluster File System)

If you are installing RAC binaries on a CFS, create the oracle base directory once, since this is a CFS

directory visible by all nodes. The CFS file system used is

/cfs/mnt1.

# mkdir –p /cfs/mnt1/oracle

# chown –R oracle:oinstall /cfs/mnt1/oracle

# chmod –R 775 /cfs/mnt1/oracle

# chmod 775 /cfs/mnt1

Change directory permission on each node.

# chmod 775 /cfs

Prepare shared storage on CFS

This section assumes the OCR, vote device, and database files are created on CFS directories. The

OCR and vote device reside on

/cfs/mnt3 and the demo database files reside on /cfs/mnt2.

Create OCR and vote device on CFS

Create directories for the OCR and the vote device on the CFS. Run these commands on one node

only.

# chmod 755 /cfs/mnt3

# cd /cfs/mnt3

# mkdir OCR

# chmod 755 OCR

# mkdir VOTE

# chmod 755 VOTE

# chown –R oracle:oinstall /cfs/mnt3

Change directory permission on each node (if needed).

# chmod 775 /cfs

Create directory for Oracle demo database on CFS

Create the CFS directory to store the Oracle database files. Run these commands on one node only.

# chmod 775 /cfs/mnt2

# cd /cfs/mnt2

# mkdir oradata

chown oracle:oinstall oradata

# chmod 775 oradata
