RESTART<br />

Authorization<br />

Purpose<br />

Oper<strong>and</strong>s<br />

MSGProc<br />

Usage Notes<br />

msgprocid<br />

Privilege Class: A, B, G<br />

The RESTART MSGPROC comm<strong>and</strong> allows a user ID to reload <strong>and</strong> start a<br />

message processor in a CF Service Machine.<br />

If you have Class G privilege only, the message processor that you specify must be<br />

currently defined in your I/O configuration. A message processor may be defined in<br />

your I/O configuration by either the DEFINE MSGPROC comm<strong>and</strong> or the SPECIAL<br />

directory statement.<br />

The RESTART MSGPROC comm<strong>and</strong> will cause the specified CF Service Machine<br />

to be loaded with the Coupling Facility Control Code (Licensed Internal Code) from<br />

the service element of the processor. Once the CF Service Machine is loaded, the<br />

message processor is restarted <strong>and</strong> all previous structures within the Coupling<br />

Facility will be lost.<br />

CAUTION:<br />

This comm<strong>and</strong> affects all coupled guests connected to the message<br />

processor.<br />

msgprocid<br />

specifies the user ID of the CF Service Machine to be restarted.<br />

1. The CF Service Machine’s console may be viewed to verify that the restart<br />

completed successfully.<br />

2. To define a virtual message processor <strong>and</strong> associated virtual message devices,<br />

use the DEFINE MSGPROC comm<strong>and</strong>.<br />

3. To display information about virtual message processors in your I/O<br />

configuration, use the QUERY VIRTUAL MSGPROC comm<strong>and</strong>.<br />

RESTART MSGPROC<br />

4. To display information about the virtual message devices within your I/O<br />

configuration, use the QUERY VIRTUAL MSGDEVICES comm<strong>and</strong>.<br />

5. To remove all message facility capability from your virtual machine, use the SET<br />

MSGFACIL OFF comm<strong>and</strong>.<br />

6. To detach a virtual message processor <strong>and</strong> associated virtual message devices,<br />

use the DETACH MSGPROC comm<strong>and</strong>.<br />

7. If an IPL directory statement or the IPL oper<strong>and</strong> on the XAUTOLOG comm<strong>and</strong><br />

was initially used to load the CF Service Machine, then the same IPL statement<br />

will be used by the RESTART MSGPROC comm<strong>and</strong> when performing the<br />

restart. The CF Service Machine will not be loaded from the service element of<br />

the processor.<br />
