Processing Topology Requests

One of the major functions of MultiSystem Manager is to process requests for topology and status of resources in your network. These requests are made by issuing GETTOPO commands for particular resources being managed by a topology agent. GETTOPO commands can be coded in the MultiSystem Manager initialization file or issued from a NetView® command line or command procedure. GETTOPO commands can be processed by MultiSystem Manager only if MultiSystem Manager is enabled.

MultiSystem Manager receives the GETTOPO request, parses it, and builds and runs a series of RUNCMD commands depending on the topology request. These RUNCMD commands are run from the specified autotask and resource topology and status is returned to MultiSystem Manager in the form of RUNCMD responses. These responses are then parsed and the topology and status information is stored in RODM.

In large, complex computing environments, you sometimes stop and restart multiple programs and processes to apply maintenance, backup data, upgrade, and so on. During such times, you might want to suspend the processing of topology requests, knowing that these requests fail until a particular process or program is restarted. MultiSystem Manager provides commands that you can use to suspend and resume MultiSystem Manager processing of topology requests.
