Pre-Installation Steps for OracleAS Cold Failover Cluster
Installing in High Availability Environments: OracleAS Cold Failover Cluster 8-5
2. Unmount the file system from node 1.
3. Mount the file system from node 2 using the same mount point that you used in
step 1.
4. Unmount it from node 2, and mount it on node 1, because you will be running the
installer from node 1.
8.2.3 Review Recommendations for Automatic Storage Management (ASM)
If you plan to use ASM instances for the OracleAS Metadata Repository database,
consider these recommendations:
■
If you plan to use ASM with Oracle database instances from multiple database
homes on the same node, then you should run the ASM instance from an Oracle
home that is different from the database homes.
■
The ASM home should be installed on every cluster node. This prevents the
accidental removal of ASM instances that are in use by databases from other
homes during the de-installation of a database Oracle home.
8.2.4 Check That Clusterware Is Running (Automated Failovers only)
If you plan to automate failovers in the OracleAS Cold Failover Cluster, then each
node in a cluster must be running hardware vendor clusterware.
To check that the clusterware is running, use the command appropriate for your
clusterware.
8.2.5 Modify listener.ora file for Existing Database
If there is an existing database on the system on which you are installing and you are
performing an installation that includes OracleAS Metadata Repository, you need to
modify the listener.ora file for the existing database before proceeding with the
installation. Perform the following steps to modify the listener.ora file:
1. Make sure you set the ORACLE_HOME and ORACLE_SID environment variables for
the existing database.
2. Stop the listener for the database:
prompt> lsnrctl stop
3. Open the listener.ora file, which is located at:
ORACLE_HOME/network/admin/listener.ora
where ORACLE_HOME is the home for the existing database.
4. Locate the LISTENER entry in the file:
LISTENER =
Note: Only one node of the OracleAS Cold Failover Cluster
should mount the file system at any given time. File system
configuration files on all nodes of the cluster should not include an
entry for the automatic mount of the file system upon a node restart
or execution of a global mount command. For example, on UNIX
platforms, do not include an entry for this file system in
/etc/vfstab
file.
