ZPSMS-Processor Status Management Services

Use this command to do the following:

Requirements and Restrictions

None.

Format




PRocessor
deactivates a processor.

FORCE
removes a processor from the loosely coupled complex. All locks held by the processor are cleared, all appropriate tables and keypoints are updated to show the processor is inactive, and all other processors in the complex are notified of the new status. Interprocessor communication (IPC) to the deactivated processor stops. The processor from which the PROC FORCE DEACTIVATE parameters are specified will take over the recovery log of the processor that will be deactivated before its locks are released.

Attention: If the processor that is being deactivated by force is the current processor, the status of the processor is not checked before the processor is deactivated. For example, the processor may be deactivated if the TPF system is not in 1052 state, if active tapes are mounted, or if there are active ECBs in the TPF system.

If the processor that is being deactivated by force is not the current processor, it is assumed that the processor is inactive and cannot respond. If this is not the case, the integrity of the complex is jeopardized.

DEACtivate id
deactivates a processor, where id is the 1-character alphanumeric CPU ID of the processor.

REServed
reserves the CPU ID for a processor. That is, the CPU ID is still associated with the CPU serial number. Otherwise, the CPU ID can be allocated to another CPU serial number.

Cycle
enables or disables cycling.

ENable
enables cycling if cycling was disabled using this command.

BP
overrides all indicators set by the TPF system that prevent cycling. If you do not specify the BP parameter, cycling can be enabled only if it was disabled using this command.

DISable
disables cycling.

SS
activates or deactivates a subsystem.

ACTivate
activates a subsystem.

DEACtivate
deactivates a subsystem.

ssname
is the 1- to 4-character name of a subsystem.

Display
displays status information about processors or subsystems.

PRocessor
displays status information about all the processors in the loosely coupled complex.

MDBF
displays status information about all the subsystems on this processor.

PRSS
displays status information about this subsystem in the loosely coupled complex.

Additional Information

Enter ZPSMS CYCLE ENABLE BP to enable cycling if cycling was disabled by the TPF system because of a system error.

Examples

The following example displays status information about all the processors in the loosely coupled complex.
