QUIESCE
If possible, all jobs currently processing terminate normally. Otherwise, current activity is suspended, and the system enters a manual state or a wait state with a code of hexadecimal 80000CCC. See z/OS MVS System Codes for more information on wait state code CCC. You might receive the following message on an MCS, HMCS or system console: 
BLW002I  SYSTEM WAIT STATE 'CCC'X — QUIESCE FUNCTION PERFORMED
Note:
  1. If this system is actively using global resource serialization to share global resources and the global resource serialization complex is not the same as the sysplex, issue a VARY GRS (*),QUIESCE command before issuing the QUIESCE command. Issuing a VARY GRS (*),QUIESCE command before issuing the QUIESCE command prevents the disruption of the global resource serialization ring.
  2. Do not issue a SYSTEM RESET after quiescing the system if you intend to issue a RESTART after the quiesce. Issuing a SYSTEM RESET will cause the system to enter an enabled wait state.
