Environment considerations
Install and configure your primary and secondary environments in accordance with your disaster recovery plan.
Installation
When install the IBM BPM or IBM Business Monitor 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. The following figure illustrates the entire test scenario example.
Figure 1. Production environment and backup environment
This example contains a total of ten servers, five for each environment (NFS server, Machine1, Machine2, Machine3, and Machine4).
Each server except the NFS server in the production 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 BPM are all installed in the /opt/ibm directory under their installation servers. DB2 is installed on Machine2, IBM BPM is installed on Machine1 and Machine2, and IBM Business Monitor is installed on Machine1, Machine3, and Machine4. For DB2, the databases related to IBM BPM and IBM Business Monitor are created under /home/db2, and the dmgr and custom profiles for IBM BPM and IBM Business Monitor are created under /home.
The dmgr files for IBM BPM and IBM Business Monitor are created on Machine1, IBM BPM custom profiles are created on Machine1 and Machine2, and IBM Business Monitor custom profiles are created on Machine3 and Machine4.
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.
Figure 2. Directories on the NFS server
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.
