OPSUSS JCL Changes

For the OPSUSS member:

• Change the STEPLIB data set names to the names specified during installation. If SYS1.OPSCCLXLOAD is in the linklist or LPALST, then you can remove it. The CCLXPLD load library should not be in the linklist or LPA since it is only used by the USS server and is an unauthorized PDSE. Change the name of this library to the name given at installation.
• The TCP/IP client data set must be allocated to the SYSTCPD DD if the following three conditions apply:
  • TCP/IP is installed on the system.
  • The TCP/IP client data set is not automatically allocated to every task.
  • The TCP/IP client data set name does not follow the dynamic allocation search sequence of TCP/IP.
• Otherwise, this DD statement may be eliminated.

  Note: If you are unsure of the correct action to take, then consult your TCP/IP Network Administrator.

• The ENVFILE data set must point to a sequential data set or PDS member that contains the names and values of environmental variables that will be set in the USS server address space and the UNIX shell that is attached by the server. Certain environmental variables must be set for the Event Management component of CCS for z/OS API calls and commands to function properly. Member USSENV00 of SYS1.OPS.CCLXCNTL contains a sample of these variables.

  Note: Variable values on each z/OS system may vary. Instructions for determining the correct variable values are contained in the sample member.

• The PARM field of the EXEC statement may contain an initial command to execute when the USS server starts. This command may be one of the following:
  • A USS shell command indicated by the keyword USSCMD and followed by the command text
  • An Event Management component of CCS for z/OS API command with the same syntax as the ADDRESS USS host command

  Do not alter the SERVER and SUBSYS keywords in the PARM field. The default command (USSCMD printenv) is a UNIX shell command that displays the values of the current environmental variables in the server shell after the ENVFILE has been processed.
