SRM
The addresses of SRM control blocks are also provided so you can modify control fields by using the ZAP service. This service also determines the current status of key SRM control values.
Syntax
The parameters are defined as follows:
Parameter | Description |
|---|---|
asi | address space instance; see Identifying-address-spaces for more information |
MAP | displays the addresses of SRM control blocks |
Example 1
To display system resource information, type
SRM
AMTS31I Address Spaces : In=42 O/Rdy=0 O/Nrdy=29 Logwt=63
AMTS32I Resource Status: CPU=8% High UIC=1800
AMTS36I Paging Rate/Sec: Demand=0 Total=45 Delay Time=16,384
AMTS39I Think-time(Sec): Cur=0.0 Min=0.0 Max=5.0
Example 2
To display the addresses of SRM control blocks as well, type
SRM MAP
[1] [2] [3]
AMTS31I Address Spaces : In=40 O/Rdy=0 O/Nrdy=29 Logwt=65
[4] [5]
AMTS32I Resource Status: CPU=2% High UIC=1900
AMTS36I Paging Rate/Sec: Demand=0 Total=0 Delay Time=22,016
AMTS39I Think-time(Sec): Cur=0.0 Min=0.0 Max=5.0
AMTS33I RMCT 0188D420 RMCA 0188DC90 RMPT 0188DC08 CCT 0188D708
AMTS34I ICT 0188D820 MCT 0188D868 LSCT 0188DE30 DMDT 022F8C40
AMTS35I CMCT 0188EBA8 CPMT 0204F3E0 CMB 00000000 CPWK 0204F3C0
Legend:
- number of address spaces currently swapped in memory
- number of address spaces swapped out of memory but ready
- number of address spaces out of memory and not ready
- current SRM-weighted percentage of CPU busy
- highest unreferenced interval count
Example 3
To display system resource information for address space BMVDWP5, type:
SRM,BMVDWP5
AMTS71I TSU09423 BMVDWP5 IKJDWP2 Service Class=TSONRM
AMTS72I Transaction data: Interval 00.00.07 [5]
AMTS73I Last Swap : Interval 00.00.07 Reason=< IN MEMORY >[6]
AMTS74I Swapping Profile: Count 1 [7]
AMTS75I Service Data : CPU 1,264 [8]
AMTS79I : SRB 29 [8]
AMTS76I : I/O 190 [8]
AMTS77I : MSO 0 [8]
AMTS78I : Total 1,483 [9]

Code
Description
ASM LOW
swapped out due to auxiliary storage shortage
ENQ EX
swapped out due to enqueue exchange

REC EX
swapped out due to recommendation values
REQUEST
swapped out due to a request swap
RSM LOW
swapped out due to a real-storage shortage
TERM IN
swapped out due to terminal input wait
TERM OUT
swapped out due to terminal output wait
UNILTRL
swapped out due to unilateral swap-out
- pages swapped at last swap-out, and the working-set size at swap-in
service units for this transaction; values are as follows:
