Administering a Multisystem Environment › Multisystem Implementation Considerations

Multisystem Implementation Considerations

When you implement your multisystem environment, consider the following:

• Ensure that the link requirements are satisfied for the planned multisystem environment
• When you link two regions, the knowledge base in the linking region is replaced by the knowledge base in the region to which you link. Implement your multisystem environment before building up your knowledge base.
• You can link a region to a focal point only. The focal point can be either a standalone region or part of a multisystem environment.
• You can link a standalone region into a multisystem environment only. You cannot link two multisystem environments together.
• For active file transfer monitoring of FTS resources both remote and local background user IDs must be defined to the FTS region.

How a Multisystem Environment Is Established

When you install your product, two databases are downloaded. These databases, which can be customized to suit your requirements, are:

• An icon panel database, where icon panel definitions are stored for the graphical monitor
• The RAMDB, where system image, resource, availability map, process, macro, command, and other definitions are stored

Together, these databases form the knowledge base.

Populate these databases with definitions specific to your environment. These definitions can include the system image definitions for any other regions that you want to install in your environment in the future.

As you establish regions, link the new regions to the first region by using the Link Region and Synchronize Database option. When databases are linked, future synchronization is automatic. Changes to the database in one region are sent to the databases in the linked regions that have visibility to those resources and system images.

Note: Synchronization does not apply to the NCL procedures represented by the registered commands and macros. Changes to these NCL procedures are not automatically reflected in the linked regions.

In a multisystem environment, you can monitor and control the resources in all linked regions from a single focal point.
