How Rules Process Host Commands

This section lists the types of host commands and explains how rule sections and types of rules process them.

ADDRESS AOF

In the )INIT and )TERM sections of all rules and the )PROC sections of all rules except command rules:

• OPS/REXX sends commands to the AOF for execution.
• Command output cannot be retrieved from the external data queue.
• OPS/REXX routes command output to the destination specified with the AOFDEST parameter.

In the )PROC section of command rules:

• OPS/REXX sends commands to the AOF for execution.
• Command output cannot be retrieved from the external data queue.
• Command output goes to the console where the command was issued.

ADDRESS EPI

In the )INIT and )TERM sections of all rules and the )PROC sections of all rules except request rules ADDRESS EPI commands are subject to NOWAIT considerations.

In the )PROC section of request rules command output can be retrieved from the external data queue.

ADDRESS ISPEXEC

In the )INIT and )TERM sections of all rules and the )PROC sections of all rules except request rules ADDRESS ISPEXEC commands are not supported.

In the )PROC section of request rules:

• ADDRESS IPSEXEC commands can execute synchronously if the OPSREQ command is issued from in an ISPF environment.
• In a server, the rules for batch execution of ISPF apply. For more information, see the IBM documentation.

ADDRESS OPER

In the )INIT and )TERM sections of all rules:

• ADDRESS OPER instructions can issue operator commands.
• Command output cannot be retrieved from the external data queue.
• OPS/REXX routes command output to either the z/OS master console or the JES3 master console.

In the )PROC section of command, DOM, EOM, global variable, message, and OMEGAMON rules:

• ADDRESS OPER instructions can issue operator commands.
• OPS/REXX cannot retrieve command output from the external data queue.
• OPS/REXX routes command output to the z/OS master console.

In the )PROC section of request and time-of-day rules:

• ADDRESS OPER instructions can issue operator commands.
• OPS/REXX can retrieve command output from the external data queue.

ADDRESS OPSCTL

You can use ADDRESS OPSCTL instructions in any section of any type of rule, but you cannot always retrieve the command output.

ADDRESS SOF

You can use ADDRESS SOF to communicate between the ADDRESS SOF host command and the CA SOF server through the CA CCI interface.

ADDRESS SQL

You can use ADDRESS SQL instructions in any section of any type of rule.

ADDRESS WTO

You can use ADDRESS WTO instructions in any section of any type of rule.

In any type of rule except for time-of-day (TOD) and request (REQ) rules, CA OPS/MVS converts to an OPSWTO command processor any ADDRESS WTO instruction that contains one of these keywords: REPLY, WAIT, or DELAY. CA OPS/MVS performs this conversion because it does not delay rule processing.

When a TOD or REQ rule contains an ADDRESS WTO command that specifies the DELAY, WAIT, or REPLY keywords, CA OPS/MVS permits the ADDRESS WTO command to execute synchronously. The TOD or REQ rule waits until the ADDRESS WTO command completes before it resumes processing.

Note: The use of the REPLY, WAIT, or DELAY keyword in a TOD rule may delay the execution of other TOD rules.
