Use this command to change from one system state to another.
Requirements and Restrictions
None.
Format
- 1052
- cycles the TPF system to 1052 state.
- CRAS
- cycles the TPF system to CRAS state.
- MESW
- cycles the TPF system to MESW state.
- NORM
- cycles the TPF system to normal (NORM) state.
- UTIL
- cycles the TPF system to utility (UTIL) state.
- ALL
- cycles all subsystems in a multiple database function (MDBF)
environment. (You can also specify this parameter for a non-MDBF
environment.)
- BP
- bypasses the check of active utility functions.
- INC
- cycles the specified subsystems.
- Note:
- You can specify this parameter only in an MDBF environment.
- EXC
- cycles all the subsystems except the specified subsystems.
- Note:
- You can specify this parameter only in an MDBF environment.
- ssname
- is the 1- to 4-character alphanumeric name of a subsystem (MDBF
only). You can specify as many as 10 subsystem names.
Additional Information
- You can cycle to the next higher state when the CRAS is inactive by
causing an external interrupt. However, when catastrophic error
recovery is being performed, causing an external interrupt will only prevent
the recovery.
- Enter the ZDSYS command to display the current system state.
Examples
The TPF system is cycled to NORM state in the following example.
+--------------------------------------------------------------------------------+
|User: ZCYCL NORM |

|System: CYCL0001I 13.32.29 CYCL TO NORM - STARTED |
| VFAC0015I 13.32.52 DELAYED FILES ENABLED |

| CVCX0001I 13.32.52 SS BSS NOW IN NORM STATE |
