JD Edwards EnterpriseOne 8.9 High Availability and Storage for the IBM eServer pSeries Client

12 JD Edwards EnterpriseOne 8.9 High Availability and Storage

3.2.2 Setting up the cluster

We set up the clustered servers based on the following sequence of actions:

1. Prepare AIX 5L Version 5.1 for clustering. Install the necessary AIX fix packs.

2. Set up HACMP/ES v5.1.

a. Install and set up HACMP/ES base software on both nodes.

b. Install and set up the latest clustering fix pack for 5.1 on both nodes prior to the initial

cluster setup.

c. Complete the HACMP/ES planning worksheets.

Refer to “HACMP/ES planning worksheets: Completed” on page 58 to see the

worksheets used for this test configuration.

d. Set up the cluster name, cluster nodes, and network interfaces to be used for the

EnterpriseOne cluster. Changes were replicated to the other node using topology and

cluster synchronization.

3. Install the JD Edwards EnterpriseOne database.

a. Install the database from the distribution media.

b. Apply the latest database fix packs that are supported by Oracle.

4. Install JD Edwards EnterpriseOne 8.9.

a. Install the EnterpriseOne 8.9 software on the deployment and enterprise servers.

b. Configure EnterpriseOne software to work with the DB2 UDB databases.

c. Create shared databases using supplied JD Edwards database creation scripts.

5. Set up HACMP/ES v5.1 for EnterpriseOne 8.9 software,

a. Application servers and resource groups for DB2 UDB and EnterpriseOne 8.9 software

(see Figure 3-2) were included.

Resource Group rgJDE controls the application server asJDE, service IP addresses

and shared SSA vgJE and vgJDE2 volume groups dedicated to the ttclrs1 node.

Resource Group rgDB2 controls the application server asDB2, service IP addresses

and shared SSA vgLData, vgJRData, and vgIndex volume groups dedicated to the

ttclrs2 node.

b. Application scripts to start up and shut down application servers in the event of failure

or resource group migration were added.

The resource groups were defined as cascading without fallback. See Chapter 6,

“Application script examples for EnterpriseOne 8.9 with HACMP/ES” on page 41.

For HACMP cluster setup, follow the guidelines in HACMP for AIX 4.5: Enhanced Scalability

Installation and Administration Guide, SC23-4306.

Table 3-1 identifies the volume groups defined for the ttclrsHA cluster.

Table 3-1 Volume groups defined for cluster ttclrsHA

When configuring volume groups for use in the clustering environment, be sure the volume

group does not automatically activate at system restart. HACMP-used volume groups are

activated when the resource group that controls that volume group is activated.

Notice that for the rgJDE resource group, the participating nodes are ttclrs1 and ttclrs2. For

the resource group rgDB2, the participating nodes are ttclrs2 and ttclrs1. The node listed first

is the primary node.

The resource groups have the additional settings listed in Table 3-2.
