HP Enterprise Cluster Master Toolkit User Guide (5900-2131, December 2011)

NOTE: This setup is not supported if Oracle 10g Release 1 is configured with LVM
or VxVM. If Oracle 10g Release 1 is configured with LVM or VxVM then local
configuration is recommended. The above configuration is supported in Oracle 10g
Release 2 and Oracle 11g, but subject to a condition that Oracle's Automatic Storage
Management (ASM) is not configured on that node.
◦ If you are using CFS:
In this setup, Oracle can be optionally installed on a CFS mounted file system
(/ORACLE_TEST0, in our example) with all Oracle binaries and configuration files
in a CFS mounted file system.
NOTE: An Oracle license must be installed on every node that might potentially
run Oracle in the cluster.
• Set up additional database logical volumes, with LVM
It is possible to have the database reside on the same volume group or logical volume
as $ORACLE_HOME/dbs, but more commonly, the database will probably reside on
several volume groups and logical volumes, which all need to be shared among the nodes
that are able to run the Oracle instances. Again, using a naming convention for the
volume group(s) that includes the instance name (${SID_NAME}) could be used to associate
a volume group with a unique instance.
For example:
Raw disk access for Oracle data:
/dev/vg01_ORACLE_TEST0/rlvol1 # Raw logical volume Oracle data
/dev/vg02_ORACLE_TEST0/rlvol1 # Raw logical volume Oracle data
/dev/vg02_ORACLE_TEST0/rlvol2 # Raw logical volume Oracle data
or for use with Asynchronous disk access and file systems:
/dev/vg01_ORACLE_TEST0/lvol1 # Logical volume Oracle data
/dev/vg02_ORACLE_TEST0/lvol1 # Logical volume Oracle data
/dev/vg02_ORACLE_TEST0/lvol2 # Logical volume Oracle data
See the Oracle documentation to determine which format is more appropriate for your
environment.
All data belonging to the database must reside on shared logical volumes (raw or file
system), space needs to be allocated and shared for the following data:
◦ Oracle tablespaces
◦ Oracle rollback segments
◦ Oracle logfiles
After defining the shared volume groups/logical volumes/file systems for these
entities, see the Oracle documentation for creating the database.
NOTE: If you are using VxVM, create appropriate disk groups as required.
If you are using CFS mounted file systems, you can have ${ORACLE_HOME}/dbs and
database reside in the same CFS file system. You can also have multiple Oracle databases
corresponding to multiple Oracle packages residing in the same CFS file system. However,
it is recommended to have different CFS file systems for different Oracle packages.
