Send Commands to CA 7 WA

There are two methods in which CA OPS/MVS can send commands to CA 7 WA. Following is a description of these two methods:

• Method 1-Issuing Commands through the ADDRESS CA7 Host REXX environment

  This method allows for a two-way interface where a CA OPS/MVS OPS/REXX program can issue a command to CA 7 WA and receive the command responses. Perform the following steps to implement this type of command interface:

  • Verify that CA 7 WA is at Release 3.3 or higher.
  • Ensure that CA GSS is active. This can be installed from the CCS for z/OS tape.
  • Add the ADDRESS CA7 IMOD to the CA GSS procedure. Contact CA 7 WA Technical Support to verify the following IMOD statement:

    ADDRESS CA7 CAL2X2WR 15 DETACH TYPE 0
    

  After all of the above requirements have been met, you can issue and receive command responses from an ADDRESS CA7 host REXX statement coded within CA OPS/MVS OPS/REXX programs. For an example of this, see member ADDRCA7 in the hlq.CCLXSAMP data set that is created during CA OPS/MVS installation.

• Method 2-Issuing Commands Through the OPS/REXX OPSCA7 Function

  This method uses the U7SVC routine to issue commands from CA OPS/MVS to CA 7 WA. With this method, command responses are not returned to the issuing CA OPS/MVS OPS/REXX rule or OPS/REXX program. No additional installation requirements are needed to use this method.

  For more information on the OPSCA7 function, see the Command and Function Reference.
