Quiesce using slow drain

When using slow drain for quiesce on a highly available system, the following steps occur on a Pega 7 Platform server when the quiesce process is enabled:

1. The default timeout for passivation is reduced, referred to as an accelerated passivation period.
2. Users are placed in a passivation queue.
3. The system stops non-essential agent processing for quiesce and all listeners, with the exception of message-driven bean (MDB) listeners. (The application server should be configured to ensure that no MDB invocations occur.)
   Note: System critical agents remain active during this step.
4. When the active user requestor count drops to 0, the system sets the server state to "Quiesce Complete" and the Pega 7 Platform server is ready for maintenance.

Note: All Pega 7 Platform servers on a physical or virtual machine must be quiesced for maintenance on the machine.
