Host Environment Commands › ADDRESS OPER Host Environment

ADDRESS OPER Host Environment

The ADDRESS OPER host environment permits you to issue operator commands from an OPS/REXX program or AOF rule. The ADDRESS OPER OPS/REXX host environment performs automated tasks with your CA OPS/MVS AOF rules and OPS/REXX programs, such as issuing z/OS, JES, subsystem, or product specific commands.

Use ADDRESS OPER to issue the following types of operator commands:

IMS Type 2 Commands

IMS Type-2 format commands are designed to be issued to the IMSPLEX Operations Manager, not any specific IMS system, and are identified to ADDRESS OPER by the presence of the keyword IMSPLEX. IMS provides a complete range of Type-2 commands, all of which must be issued in Type-2 format, and also allows some existing Type-1 commands to be issued directly to the Operations Manager using the Type-2 syntax. Upon receiving a Type-2 command, the manager distributes the work to participating IMS systems, and returns all collected output to the original issuer of the command.

The SYSID/SYSTEM parameters provide a method for remote execution. If a command is directed to a remote system through an MSF connection, the remote system must have the following configured properly:

• An active IMS configured for Type2 message execution
• Any IMSPLEX considerations unique to that system

System-related keywords such as the IMSPLEX name, apply to the remote system. The sending system does not perform any IMS functions, and does not require an active IMS to be running.

JES

Prefix JES2 commands with a dollar sign ($). Prefix JES3 commands with an asterisk (*).

MVS (or MVS/JES3)

There is a limit to the number of output lines CA OPS/MVS can capture, but it is so large that truncation is unlikely.

VM

Prefix VM commands with a pound sign followed by the letters CP (#CP). The CA OPS/MVS product issues VM commands using the standard z/VM Diagnose Interface, which has these requirements:

• A buffer, which is used to return the response to the VM command, must be passed to the Diagnose Interface.
• The buffer must be contiguous in real memory (as seen by z/OS).

Because there is no z/OS mechanism for allocating contiguous real memory, VM command responses are limited to the size of a single real storage frame, which is 4 KB.
