Using SSM Global Application › How SSMGA Works

How SSMGA Works

The global system in the SSMplex does the following:

• Maintains its own consolidated local resource status in a single RDF table called the LST (local status table)
• Moves resources
• Maintains the consolidated resource status of all local systems in another RDF table called the GST (global status table)
• Examines changes in the prerequisite and group names resource columns
• Processes the SSMGA commands generated by the SSMGAOPR command rule and queued to the global command RDF table for execution.

Important: Resources defined to Schedule Manager cannot be defined as movable resources to SSMGA.

The advantages of global status management are a high level of multi-tasking and minimal data transfer between systems. Recovery from a global system failure is reduced to selecting a new global system and rebuilding the GST from the remaining systems LST tables.
