Task Structure for Processor Operations

For processor operations there is a task structure that is modular; distinct types of SA z/OS tasks handle different work assignments.

The types of SA z/OS tasks are:

  • Target control tasks
  • Message monitor tasks (used for SNMP and TCP/IP connections only)
  • Recovery task
  • Start task
  • Polling task

SA z/OS allows up to 999 tasks of each of the first three types, but only one recovery task and one processor operations start task. Because SA z/OS tasks are z/OS tasks that require system services and also add to the load running in the NetView address space, you should only define as many tasks as are needed.

The following guidelines help you match the number of SA z/OS tasks to your SA z/OS configuration.
  • The number of message monitoring tasks for target systems connected with a SNMP connection should be identical to the number of target control tasks in your environment.
  • The number of target control tasks should be less than or equal to the number of target hardware defined. If you plan to use the processor operations group and subgroup support for the common commands, the total number of target control tasks should be equal to the number of concurrently active target hardware systems.
  • In consideration of focal point performance, limit the total number of tasks to a number your system can handle.
