SCS Address Space Administration › MSMCPROC JCL Procedure

MSMCPROC JCL Procedure

The SCS address space uses the MSMCPROC JCL procedure. Copy this procedure to a system PROCLIB that the z/OS START commands use, and modify it to suit your installation environment.

You can:

• Specify the JCL EXEC statement parameters that can be used with the PARM keyword parameter of the JCL EXEC statement.
• Add or change any DD statements as required. The MSMCPROC sample member describes the changes that are required.

  Note: MSMCPROC is the common name of the SCS address space JCL procedure. You can change the name to suit your installation environment.

If the z/OS UNIX System Services environment on your system is not configured with an AF_INET6 domain in the SYS1.PARMLIB(BPXPRMxx) member, update the TCP/IP parameters in the SCS address space parameter member MSMCPARM. Change <TCPIP ipaddr="::" port="49152"/> to <TCPIP ipaddr = "0.0.0.0" port="49152"/>.

Define a security system user ID for the SCS address space. The user ID must have an OMVS segment. The segment must be defined and have read access to the data sets that the SCS address space JCL procedure allocated. The user ID does not need OMVS superuser privileges.

You can start the SCS address space as a started task or as an initiated job.

• To start the SCS address space as a started task, use the START command. Use your security system to associate a user ID with the SCS address space started task.
• To start the SCS address space as an initiated job, execute the MSMCPROC JCL procedure within a batch job stream. Use the USER parameter of the JCL JOB statement to associate a user ID with the SCS address space initiated job.
