Fields

Table 3. Fields in MVSWLM views
Field	Attribute name	Description
CEC machine type	MNGMCHTP	CEC machine type for the address space.
CEC model number	MNGMDLID	CEC model identification number for the address space.
Adjustment value for z/OS WLM health	MNGWLMAD	For CICS regions at level CICS TS 5.4 and higher, this is the current adjustment value that adjusts z/OS WLM health in the CICS address space at each interval
CPU critical	MNGWLMCC	Indicates whether or not the CICS region is defined to the MVS workload management component with long-term CPU protection. Values are: Yes The CICS region is defined in the JES (batch job) or STC (started task) subsystems using a MVS workload manager service class that specifies CPU critical. No The CICS region is defined in the JES (batch job) or STC (started task) subsystems using a MVS workload manager service class that does not specify CPU critical.
Goal importance	MNGWLMGI	Indicates the relative importance level defined in the MVS workload manager service class. Values are: 1 Highest 2 High 3 Medium 4 Low 5 Lowest
Goal management	MNGWLMGM	Indicates whether z/OS Workload Manager manages the address space using transaction goals, region goals or both. Values are: Transaction Workload manager uses transaction goals Region Workload manager uses region goals Both Workload manager uses both goals Notapplic Unknown or undefined goal mode
Goal type	MNGWLMGT	The MVS workload manager goal type associated with the current service class. Values are: Velocity The MVS workload management component will assign resources to the service class in order to minimize delays. Discretionary The MVS workload management component will assign resources to the service class only if they are not required by other non-discretionary goals. This is typically used for low priority work. System The service class is one of the MVS workload manager predefined service classes; SYSTEM, SYSSTC, or SYSOTHER. Notapplic Unknown or undefined goal type.
Velocity goal value	MNGWLMGV	For MVS workload manager service classes that use a velocity goal this value indicates the acceptable amount of delay for the work. This value will be 0 if the service class is not defined with a velocity goal.
z/OS WLM health	MNGWLMHL	For CICS regions at level CICS TS 5.4 and higher, this is the percentage value that represents the z/OS WLM health open state for the region. A value of N/A is returned if WLMHEALTH=OFF is set in the SIT.
Last time z/OS WLM health was updated	MNGWLMHT	For CICS regions at level CICS TS 5.4 and higher, this is the last time, in ABSTIME format, when z/OS WLM health was reported to z/OS WLM.
Time interval (seconds) between z/OS WLM health updates	MNGWLMIN	For CICS regions at level CICS TS 5.4 and higher, this is the amount of time, in seconds, between calls that CICS make to the z/OS Workload Manager Health API
Goal mode	MNGWLMMD	Indicates whether the MVS workload management component is running in goal mode. Values are: Yes The MVS workload management component is running in goal mode. No The MVS workload management component is running in compatibility mode. Note - compatibility mode is only available on z/OS releases prior to z/OS V1R3.
z/OS WLM health open status	MNGWLMOS	For CICS regions at level CICS TS 5.4 and higher, this is the status of the z/OS WLM health process. The CVDA values are as follows: OPEN - Instructs CICS to start increasing z/OS WLM health until it has reached a value of 100 where it will remain in the OPEN state OPENING - CICS has started increasing z/OS WLM health, which is currently in the range 0 through 99. CLOSE - Instructs CICS to start decreasing z/OS WLM health until it has reached a value of 0. CLOSED - CICS has completed decreasing z/OS WLM health, which has reached a value of 0. CLOSING - CICS has started decreasing z/OS WLM health to 0, which is currently in the range 100 through 1. IMMCLOSING - CICS is in the process of immediately setting z/OS WLM health to 0. IMMCLOSE - Instructs CICS to immediately set z/OS WLM health to 0.
Report class	MNGWLMRC	Identifies the name of the MVS workload manager report class that has been assigned to the CICS region on the basis of the JES (batch job) or STC (started task) startup subsystem. If no report class has been assigned, this field will be blank.
Resource group	MNGWLMRG	Identifies the name of the MVS workload manager resource group that has been assigned to the CICS region on the basis of the JES (batch job) or STC (started task) startup subsystem. If no resource group has been assigned, this field will be blank.
Service class	MNGWLMSC	Identifies the name of the MVS workload manager service class that has been assigned to the CICS region on the basis of the JES (batch job) or STC (started task) startup subsystem.
Storage critical	MNGWLMSK	Indicates whether or not the CICS region is defined to the MVS workload management component with long-term storage protection. Values are: Yes The CICS region is classified in the JES (batch job) or STC (started task) subsystems using a MVS workload manager classification rule that specifies storage critical. No The CICS region is not classified in the JES (batch job) or STC (started task) subsystems using a MVS workload manager classification rule that specifies storage critical. Long-term storage protection will be assigned under the JES (batch job) or STC (started task) subsystems as long as the service class has a single period and has a velocity goal or response time goal of over twenty seconds.
WLM server	MNGWLMST	Identifies whether or not the MVS workload management component is treating the CICS region as a server. Values are: Yes The MVS workload management component is treating the CICS region as a server and processing work based upon CICS subsystem definitions. No The MVS workload management component is treating the CICS region as a non-server address space. Work is being processed based upon JES (batch job) or STC (started task) subsystem definitions.
Workload name	MNGWLMWN	Identifies the name of the MVS workload management component workload name that has been assigned to the CICS region on the basis of the JES (batch job) or STC (started task) startup subsystem. Note - this is different from the CICSPlex SM workload name that the CICS region may be participating in.
