Once you have reviewed and modified all of the JCL you can move on to configuring the z/Server feature itself. The configuration for z/Server is stored in XML format and is in hlq.MFA.CNTL(MFAXML).
<Configuration
TCP_PORT="2020"
NETWORK_ID="DDINET1"
LU62_APPLID="MFM62ACB"
APPLID_PASSWORD="MFM62PSW"
TRACING="0"
ORGANIZATION="YOUR_COMPANY_NAME"
SVC_NO="NNN"
DSP_TOKEN="TAURSERV"
IPSTACK="TCPIP"
>
...
<!-- Application Server address space definitions -->
<ApplicationServers>
<!-- z/Server Scheduler -->
<Scheduler SCHEDULER_NAME="TAURISPF" LISTENER_PORT="1200"
FIRST_PORT="1201" LAST_PORT="1249"
USER_SERVER_JOBNAME="IVPUSRT" CCSID="037"
DEFAULT="1"
>
<UserServer CCSID="037" />
</Scheduler>
</ApplicationServers>
...
</Configuration>
The aspects of z/Server's behavior that you want to modify determine the parts of the XML that you need to edit.
