Sun Cluster 2.2 Overview

A cluster is a group of completely separate systems that are networked together to work towards a common goal. Within each node, a fully functional standalone server system exists. Once in a clustered configuration, the nodes work together as a single entity to cooperatively provide applications, system resources, and data to the user community.

Sun Cluster 2.2 is the software application used in this project to provide HA for Oracle 8.1.6. One node will act as the main oracle database server, while the other shall serve as a backup. We are not running Oracle OPS. The architecture and environment are as follows:

Required Patches

The following patch numbers are required after installing Sun Cluster 2.2

109208-01 109427-01

The steps to configure and install Sun Cluster are grouped into three procedures:

1. Preparing the administrative workstation and installing the client software.
2. Installing the server software
3. Configuring and bringing up the cluster.

How to Prepare the administrative workstation and install the client software

1. Install Solaris 8 operating environment on the administrative workstation.
2. Install Solaris patches.
3. For convinience, add the tools directory /opt/SUNWcluster/bin to the PATH on the administrative workstation.
4. Load the Sun Cluster 2.2 CD-ROM on the administrative workstation.
5. Use scinstall to install the client packages on the administrative workstation.

a. As root, invoke scinstall
# cd /cdrom/suncluster_sc_2_2/Sun_Cluster_2_2/Sol_2.8/Tools
# ./scinstall
b. Select the client package set.
c. Choose an install path for the client package
d. Install the client package

6. Change the port number used by the Sun Cluster SNMP daemon and Solaris SNMP
7. Modify the /etc/clusters and /etc/serialports files. These files are installed automatically by scinstall.

How to install the Server Software

After you have installed the Sun Cluster 2.2 client software on the administrative workstation, use this procedure to install Solaris and the Sun Cluster 2.2 Server software on all cluster nodes.

Pre-Installation Phase

1. What is the name of the cluster? wlsora
2. How many nodes will be in this cluster? 2
3. How many nodes will be active in the cluster? 2
4. Type of Network Interface? ethernet
5. Hostname, IP address, and ethernet address for all nodes in cluster?
   

   wlsora1 (08:00:20:c6:1d:cf)	192.29.61.100
   wlsora2 (08:00:20:c6:1e:bd)	192.29.61.101
   wlsora-tc	192.29.61.141
   wlsoracle	192.29.61.142
   wlsadm	192.29.61.140

   
   
6. PCI Slot Assignment:
   

   Machine	wlsora1	wlsora2
   PCI1	GBIC (Top box a)	GBIC (Bottom Box a)
   PCI2	GBIC (Top box b)	GBIC (Bottom Box b)
   PCI3	Quad Ethernet (Sec)	Quad Ethernet (Sec)
   PCI4	Fast Ethernet (Pri)	Fast Ethernet (Pri)

   
   
7. What data services will be used? oracle
8. Mount the suncluster 2.2 CD to each respective node:
   # mount wlsadm:/soft /soft
9. On the administrative workstation, start up the cluster console:
   wlsadm# ccp wlsora
10. Change to the directory where the Sun Cluster 2.2 Software is mounted.
11. Run ./scinstall
