Next you would be presented with
‘Specify Location Page’ (as shown in Fig. 6.7) Ensure that the
source points to the software location, which is either the software
CD directory or the location of the directory where the software is
copied. Also specify the CRS Home Name and its location. Cluster
Ready Services should be installed in a separate Oracle Home, which
is different from the RAC Database Oracle Home. The CRS home
directory is the directory where you choose to install the software
for Oracle Cluster Ready Services.

In the next step, you will make the language
selection. After that you will be asked to provide a Cluster Name
and also the private and public host names for the nodes in the
cluster. In our example, Cluster Name is specified as PROD and
public node names are shown as node1, node2 and node3. Private host
names are shown as rac1-2, rac2-2 and rac3-2. Oracle uses the
private Network for Cache Fusion block transfers and inter-node
messages. Also note that the Cluster Configuration Information page
(Fig. 6.8) contains pre-defined node information if the OUI detects
that your system has vendor clusterware.

In the next page, identify the interfaces to
use as private interconnect. In our example, we have provided ‘eth2’
as the private interconnect interface.

Next, the Cluster Registry Location Information
page is shown. Enter the complete path for the raw device or shared
file system file for the Oracle Cluster Registry (OCR). In our
example, we have entered /mnt/ps/db/ocr, which is located on a
cluster file system. The OCR stores the cluster nodes information.
(as in Fig. 6.10) This file should be about 100MB. In our
installation, we have used the Polyserve Cluster file system and we
have pre-created the OCR file as shown below.
