Walkthrough

This example uses a procmap to identify which SAP processes are batch and which are dialog, and

separately place them in different gWLM workloads. To do that, there is some additional setup before

we can define our SRD and workloads.

Confirming SGeSAP is categorizing processes

To confirm that SGeSAP tools are producing a list of PIDs, check for the existence of a map file for

your instance. For our example instance C03, this means:

root@cutst125:/tmp ls /etc/cmcluster/C03/wlmprocmap.*

/etc/cmcluster/C03/wlmprocmap.C03_DVEBMGS00_cutst125

/etc/cmcluster/C03/wlmprocmap.C03_DVEBMGS00_cutst128

Then check the contents of those files to confirm the PIDs listed do indeed map to SAP processes.

Example to check that the first PID listed is an SAP process:

root@cutst125:/tmp cat

/etc/cmcluster/C03/wlmprocmap.C03_DVEBMGS00_cutst125

DIA:7926

DIA:7927

DIA:7928

DIA:7929

DIA:7930

DIA:7931

UPD:7932

UPD:7937

UPD:7952

UPD:7953

UPD:7954

BTC:7956

BTC:7961

SPO:7962

UP2:7966

UP2:7980

root@cutst125:/tmp ps -ef | grep 7926 | grep -v grep

c03adm 7926 7919 0 20:45:43 ? 1:08 dw.sapC03_DVEBMGS00

pf=/usr/sap/C03/SYS/profile/C03_DVEBMGS00_cutst125

Creating the procmap and the procmap-based workload

Now we will create small procmap scripts that will execute the wlmsapmap tool against the mapfile

and return just batch or dialog PIDs:

root@cutst125:/tmp cd /etc/opt/vse/scripts/

root@cutst125:/etc/opt/vse/scripts cat > dialog.C03_DVEBMGS00

#!/bin/sh

/opt/wlm/toolkits/sap/bin/wlmsapmap \

-f /etc/cmcluster/C03/wlmprocmap.C03_DVEBMGS00_cutst125 -t DIA

root@cutst125:/etc/opt/vse/scripts

root@cutst125:/etc/opt/vse/scripts chmod 0755 ./dialog.C03_DVEBMGS00

root@cutst125:/etc/opt/vse/scripts ./dialog.C03_DVEBMGS00

28095 28096 28097 28098 28101 28102

root@cutst125:/etc/opt/vse/scripts cat >

/etc/opt/vse/scripts/batch.C03_DVEBMGS00

#!/bin/sh

/opt/wlm/toolkits/sap/bin/wlmsapmap \

-f /etc/cmcluster/C03/wlmprocmap.C03_DVEBMGS00_cutst125 -t BTC

root@cutst125:/etc/opt/vse/scripts chmod 0755

/etc/opt/vse/scripts/batch.C03_DVEBMGS00
