10.2 Setting up the OracleAS Disaster Recovery Environment
Before you can install Oracle Application Server in an OracleAS Disaster Recovery
environment, you have to perform these steps:
■
Section 10.2.1, "Ensure Nodes Are Identical at the Operating System Level"
■
Section 10.2.2, "Set Up staticports.ini File"
■
Section 10.2.3, "Set Up Identical Hostnames on Both Production and Standby Sites"
■
Section 10.2.4, "If You Want to Use OracleAS Cold Failover Cluster on the
Production Site"
10.2.1 Ensure Nodes Are Identical at the Operating System Level
Ensure that the nodes are identical with respect to the following items:
■
The nodes are running the same version of the operating system.
■
The nodes have the same operating system patches and packages.
■
You can install Oracle Application Server in the same directory path on all nodes.
10.2.2 Set Up staticports.ini File
The same component must use the same port number on the production and standby
sites. For example, if Oracle HTTP Server is using port 80 on the production site, it
must also use port 80 on the standby site. To ensure this is the case, create a
staticports.ini
file for use during installation. This file enables you to specify
port numbers for each component. See Section 2.5.3, "Using Custom Port Numbers
(the "Static Ports" Feature)" for details.
