Operating system considerations
Verify that the basic operating system configurations for the primary and secondary environments are the same.
For example, if there are five operating system configurations in the primary environment, there must be five operating system configurations in the secondary environment. The configurations in the secondary environment must have the same operating system version and file system hierarchy.
The host name and the IP configuration of the primary and secondary environments appear in both the database and the IBM BPM configuration data.
Tip: Configure the same IP and host name for each pair of primary and secondary operating systems. Otherwise, you have to update the IP and host name information inside the configuration file when data moves from the primary environment to the secondary environment.
In the examples in the topics that follow, all operating systems are deployed with Red Hat Enterprise Linux.
- Snapshot support
If you want to back up the primary environment without affecting normal functioning, you need the additional support of an operating system snapshot.
- NFS support
In a distributed environment, the data of the production environment is distributed over several operating systems. Without special configuration, during run time, it is highly possible to get an inconsistent copy of the entire environment even when you use a snapshot. A consistent copy of the entire environment is required to ensure the proper behavior of the system. To ensure consistency, you can use a Network File System (NFS).
