Address Space List screen

The Address Space List screen summarizes current address space activity on your system. Address spaces that are currently in storage are highlighted. From this screen, you can enter line commands to navigate to other screens.

This screen is invoked from the CMFMON Primary Option Menu or by entering an ASL command from any CMFMON Online screen.

Note

This screen is available only in the CMFMON Online facility. There is no CMFMON batch report equivalent.

The following table lists the header; ID (used when specifying keywords); whether the column appears in Total mode, Delta mode, or both modes; and a brief description of each column in this report.

Column descriptions for the Address Space List report

Column Header	Column ID	Mode	Description
SEL	SEL	Both	Input field that allows you to fastpath to one of three address space screens for a specific job name. In the SEL field next to the desired job in the JOBNAME column, enter one of the following values: ARD to display the Address Space Resource Data screen ASD to display the Address Space State Data screen ASRM to display the Address Space SRM Data screen for that job
JOBNAME	JOBNAME	Both	One- to eight-character name associated with the address space
AST	AST	Both	Contains the type of the address space; valid values are as follows: ASC-APPC address space JOB-Batch job MNT-Mount task OMV-OpenEdition address space STC-Started task TSU-TSO user
ASID	ASID	Both	Address space identifier of the job as assigned by the system
ASIDX	ASIDX	Both	Hexadecimal representation of the address space ID
SERVICE CLASS	SRVCLASS	Both	One- to eight-character name of a service class or a report class
S P	SERV_PER	Both	Service Class Period field—contains the performance period of a service class; possible values range from 1 to 8
C L	CL	Both	Current Location field—contains two characters identifying the current location of the job; possible values are as follows: IN-In storage OT-Swapped out and ready LO-Logically swapped out NS-Non-swappable WM-Wait queue: MSO WL-Wait queue: long wait WT-Wait queue: terminal wait WO-Wait queue: reasons other than WM, WL, or WT DL-RTO delay PR-Privileged >>-Currently being swapped out << -Currently being swapped in
R LS	RLS	Both	Reason: Last Swap field —contains two characters identifying the reason for the last swap out with the job. Possible values for this field are as follows: TI-Terminal input wait TO-Terminal output wait LW-Long wait XS-Auxiliary storage shortage MP-Memory pool shortage (PTF BPP0309 applied) DW-Detected wait RS-Real storage shortage NQ-Enqueue exchange EX-Exchange swap based on recommendation value US US-Unilateral TS-Transition swap IC-Improve central storage usage IP-Improve system paging rate MR-Make room to swap in a user that has been swapped out too long AW-APPC wait IW-OMVS input wait OW-OMVS output wait If the current location of the job is NS, IN, or PR, this field is blank.
DP PR	DPPR	Both	Dispatch Priority field—contains the ASCB dispatch priority for the address space Address spaces compete with each other for processor time based upon their dispatching priorities. Priorities range from 1 to 255, and are specified in SYS1.PARMLIB (IEAIPSxx).
XDP PR	XDPPR	Both	Hex Dispatch Priority field—contains a hexadecimal representation of the dispatching priority for the domain Address spaces compete with each other for processor time based upon their dispatching priorities. Priorities range from 1 to 255, and are specified in SYS1.PARMLIB (IEAIPSxx).
PAGE RATE	PAGERATE	Total	Rate per second of pages being brought into central storage for a job For cross-memory address spaces: Page-in rate = Number of page-ins / Transaction residency time For all other address spaces: Page-in rate = Number of page-ins / Seconds of CPU time The number of page-ins is the sum of the number of pages brought into central storage, one at a time.
DCPU TIME	DCPUTIME	Delta	Delta CPU Time field—contains the number of CPU seconds used by the job since you last pressed Enter; this figure is known as the delta value Warning Note This field is available only if the job was present in the previous snapshot (that is, the last time you pressed Enter) and the job is still in the same step in the current snapshot. If this condition is not met, this field is blank. To return to total mode—in which this field reflects the rate at which CPU is being utilized by the job—enter DElta OFF on the COMMAND line.
CPU RATE	CPURATE	Total	Contains the percentage of CPU time used by the job since you last pressed Enter The value is adjusted for multiple CPUs, if applicable, but is not adjusted for partition weights. Warning Note This field is available only if the job was present in the previous snapshot (that is, the last time you pressed Enter) and the job is still in the same step in the current snapshot. If this condition is not met, this field is blank. When you first display the ASL screen, this field always contains blanks because there is no previous snapshot. To see the delta value—that is, the actual number of CPU seconds used by the job between snapshots—enter DElta OFF on the COMMAND line.
DELT EXCP	DELTEXCP	Delta	Delta EXCP Count field—contains the number of SSCH instructions issued by the job since you last pressed Enter; this figure is called the delta value Warning Note This field is available only if the job was present in the previous snapshot (that is, the last time you pressed Enter) and the job is still in the same step in the current snapshot. If this condition is not met, this field is blank. To return to total mode—in which this field reflects the rate at which SSCH instructions are being issued—enter DElta OFF on the COMMAND line.
EXCP RATE	EXCPRATE	Total	Contains the number of SSCH instructions issued per second for the current transaction: delta(SSCH count) / elapsed time Warning Note This field is available only if the job was present in the previous snapshot (that is, the last time you pressed Enter) and the job is still in the same step in the current snapshot. If this condition is not met, this field is blank. When you first display the ASL screen, this field always contains blanks because there is no previous snapshot. To see the delta value—that is, the actual number of SSCH instructions issued by the job between snapshots—enter DElta ON on the COMMAND line.
REAL	REAL	Both	Real Storage field—contains the amount of real frames in central storage occupied by the address space
X M	XM	Both	Cross Memory field—contains an X for address spaces considered to be cross memory address spaces This statement implies that the address space provides services used by other address spaces, and that the address space is accessed in cross memory mode. If the address space is not a cross memory address space, this field is blank.
A	A	Both	ACTIVE field—contains Y if the address space is active and N if it is inactive An address space is considered active if it is currently swapped in executing non-swappable executing in privileged mode Specify a filter of Y if you want to display only active address spaces; specify a filter of N to display only inactive address spaces.
WORKLOAD	WORKLOAD	Both	One- to eight-character name of a workload A workload is a group of work to be monitored, managed, and reported. It consists of one or more service classes.
RESOURCE GROUP	RESOURCE	Both	One- to eight-character name of a resource group A resource group is an amount of processor capacity. It has minimum and maximum capacity values. Assigning a service class to a resource group effectively guarantees a minimum capacity and sets a maximum capacity for the transactions belonging to the service class.
