Slow drain quiesce

Slow drain for quiesce on a highly available system is not the default. The following actions occur on a Pega Platform server when the quiesce process is enabled.

• The default time out for passivation is reduced, referred to as an accelerated passivation period.
• Users are placed in a passivation queue.
• The system stops non-essential agent processing for quiesce and all listeners, with the exception of message-driven bean (MDB) listeners.
  Note: System critical agents remain active during this step.
• When the active user requestor count drops to 0, the system sets the server state to "Quiesce Complete" and the Pega Platform server is ready for maintenance.
