Activate SSTM for your Enterprise Server region

To activate SSTM for your Enterprise Server region, you provide some initialization JCL and set the environment variable ES_SSTM_CICS to reference it. This information is picked up as your Enterprise Server region starts.

Example settings

SSTM initialization JCL
```
//SSTMJCL JOB 'CICS JOB',MSGCLASS=A
//CICS     EXEC PGM=NOTUSED
//SYSOUT   DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//TEMPJCL  DD DSN=&&TEMPJCL,DISP=NEW
//OUTJCL   DD DSN=CICS.SSTM.OUTJCL,DISP=(MOD,CATLG)
```
Note that the program name in the PGM= entry must be syntactically correct, but it does not need to exist. The DD OUTJCL is shared across CICS SEPs, but the other DDs are not shared, and are local to each SEP.
ES_SSTM_CICS
```
ES_SSTM_CICS=C:\ES\SSTM\JCL\SSTMCICS.JCL
```
This environment variable is set in the General tab of Enterprise Server Administration, in the Configuration Information section, for example:
```
[ES-Environment]
ES_SSTM_CICS=C:\ES\SSTM\JCL\SSTMCICS.JCL
```

You will need to restart your Enterprise Server region for these changes to take effect. The message SSTM environment established successfully appears in the output console after a successful restart.
