Automated pause and resume flow

The IPA system has an automated pause and resume functionality triggered during a server shutdown. When a server shutdown occurs, the system attempts to pause any actively running work units. These paused work units resume on another available server within approximately one minute, or when a new server becomes available. The mechanism is designed to pause as many work units as possible, but it does not guarantee that all work units are successfully paused. This functionality currently applies only to non-production work units.

These are the criteria for pausing work units:
  • Auto-restartable processes
    • The work units associated with auto-restartable processes are generally paused.
    • A work unit is not paused if it has been running within a single activity node for more than ten minutes.
  • Non-auto-restartable processes
    • The IPA system still attempts to pause a work unit even if the process is not marked as auto-restartable.
    • A work unit is paused only if it is not running inside an iteration loop.
    • A work unit is not paused if it has been running within a loop for more than ten minutes.
