Issuing Cross-System Commands from a z/VM System

After you create a linkage and set up the proper authority level, you can issue cross-system commands from z/VM to a z/OS or another z/VM system. The authority level you assigned to that linkage determines what types of cross-system commands you can issue through the linkage.

To issue cross-system commands on a z/VM system, use the following format:

MI scope command
MI

This is the CA MIM for z/VM command prefix. You can also use the CP SMSG command to send the command to the MIMGR service machine.

scope

This identifies the systems on which the command should be executed. Specify one of the following values:

sysid

Specifies the IDs of the systems to which you are directing your command. You can specify the full system name, two-character system alias, or the system index number.

ALL

Directs your command to all systems in the MIMplex, except ICMF systems.

EXTERNAL

Directs your command to all systems in the complex, except the local system and ICMF systems.

LOCAL

Directs your command to the local system.

command

Specifies the command to be executed on z/OS or z/VM.

Example:

To execute the z/OS DISPLAY REPLIES command on system SYS390 from your z/VM system, issue the following command:

MI SYS390 DISPLAY REPLIES,LOCAL

The first line of a command response shows the z/OS job stamp or CMS user ID associated with that response. This field may be blank for system command responses. If GCMINIT EDITMESSAGE=EXTERNAL was set for the system where the command executes, the job stamp or user ID field will be edited to contain the system alias of that system. This permits you to see which system is responding to a cross-system command you issued to more than one system.

Responses are returned to the issuing user through MSGNOH, if possible. If the CA MIM for z/VM service machine does not have the CP privilege class for the MSGNOH command, the responses are returned using MESSAGE rather than MSGNOH.

For information on issuing cross-system commands from a z/OS system, see the CA MIC Message Sharing for z/OS Programming Guide.
