Install and configure your primary and secondary environments in accordance with your disaster recovery plan.

Installation

When you install the IBM® Business Automation Workflow environment as the root user, there are no special instructions for the primary environment.

For the secondary environment, reinstall the environment with the same information, such as installation path, product version, and patch level, as in the primary environment.

Configuration

Configuration includes creating profiles and configuring cluster environments.

When you create profiles in the primary environment, the profile path must be located in the directory that is targeted at the NFS server. In the secondary environment, the same directory of the corresponding operating system must be mounted on the NFS server. No configuration is required before the restoration.

To configure the cluster environment, follow the normal process of cluster configuration.

Each server except the NFS server in the secondary environment has the same IP address and host name as the one in the primary environment. The NFS servers in the two environments have different IP addresses and host names.

Db2® and IBM Business Automation Workflow are all installed in the /opt/ibm directory under their installation servers. IBM Db2 is installed on Machine2, IBM Business Automation Workflow is installed on Machine1 and Machine2. For Db2, the databases related to IBM Business Automation Workflow are created under /home/db2, and the dmgr and custom profiles for IBM Business Automation Workflow are created under /home.

The dmgr files for IBM Business Automation Workflow are created on Machine1, IBM Business Automation Workflow custom profiles are created on Machine1 and Machine2.

The following figure provides more information about the test scenario example. The structure in the figure is just an example. You can arrange your directories according to the requirements of your system.

With this structure, to back up all profiles and database files, you can conveniently take a snapshot of the /home directory under the NFS server. Alternatively, you could separate the runtime data from the configuration data and make snapshots for them individually.

Tip: Keep the backups as small as possible because otherwise your processing time could be greater than your recovery time objective.
