Syntax of OPSPARM for Changing Parameters

To change parameters, use the following syntax:

OPSPARM
{SET(parmname)}
{VALUE(parmvalue)}
[SUBSYS(ssid)]
[SYSTEM(sysname|ALL|EXT)]
[SYSWAIT(seconds)]

SET and VALUE

Always specify the SET and VALUE keywords together to identify the name of the parameter to be changed and the new value for the parameter. For example:

OPSPARM SET(OSFMAX) VALUE(3)
OPSPARM SET(SYSID) VALUE(PRODSYS)

If you specify an invalid parmname, the OPSPARM command processor issues an error message and a return code of 60.

SUBSYS

(Optional) When you reset a parameter, the SUBSYS keyword identifies the specific copy of CA OPS/MVS whose parameter this OPSPARM command will change. You must use the SUBSYS keyword when resetting parameters, except in these situations:

When the OPSPARM request is addressed to the copy of CA OPS/MVS using the default z/OS subsystem identifier (usually OPSS)

When the OPSPARM request is issued by a CLIST running in an address space belonging to a specific copy of CA OPS/MVS.

Note: This address space can be the OPSMAIN address space itself, one of its OPSOSF address spaces, or an OPSECF address space it started.

SYSTEM Keyword (Used with SET)

(Optional) The SYSTEM keyword provides CA OPS/MVS with the capability to execute the OPSPARM command on external systems that have been defined to the MSF. The MSF establishes VTAM sessions between copies of CA OPS/MVS, permitting any copy to issue a command on any other copy and to receive its response.

When used with the SET keyword, the SYSTEM keyword indicates one of the following:

The name of the system on which the SET command is to execute; to indicate this, specify a value for sysname
The SET command should execute on all active systems other than the local system; to indicate this, specify EXT
The SET command should execute on all active systems; to indicate this, specify ALL

Note: As referred to here, active is the status of the MSF systems through which the communication takes place.

SYSWAIT Keyword (Used with SET)

(Optional) Use the SYSWAIT keyword to specify the number of seconds that CA OPS/MVS waits for a response from a remote system. You can specify a value from 1 to 300; the default is the MSFSYSWAIT value.

Examples: SYSTEM Keyword Used with SET

In this OPSPARM command, the SYSTEM keyword specifies that the OCWAIT parameter is to be set to 7 on system SYSA:
```
OPSPARM SET(OCWAIT) VALUE(7) SYSTEM(SYSA)
```
In this example, the SYSTEM keyword specifies that the OCWAIT parameter is to be set to 9 on all systems except the local system:
```
OPSPARM SET(OCWAIT) VALUE(9) SYSTEM(EXT)
```
This example indicates that the OCWAIT parameter is to be set to 8 on all systems including the local one:
```
OPSPARM SET(OCWAIT) VALUE(8) SYSTEM(ALL)
```
