Introduction:

Mainframe CA Datacom Server startup option SUPMSG can be used to monitor the connections to the server, including the task number, user ID, date, and time. SUPMSG can also be issued and modified as a console command.

Background:

There may be a need to monitor the connections to a CA Datacom Server periodically. SUPMSG option can be used to monitor those connections via the following messages:

 

DSV00035I Workstation connected to Server.

Reason: A workstation was successfully connected to this server. Task number, user ID, date, and time follow this message.

 

DSV00036I Workstation connection was terminated.

Reason: A workstation connection to this server was terminated. The workstation requested to be disconnected, the connection was timed out, or a cancel was requested throughout the batch communication utility program.

 

 

Environment:
z/OS
Instructions:

In the CA Datacom Server mainframe start options, optionally specify:

SUPMSG=value

(Optional) Denotes whether the connect/disconnect messages, DSV00035I and DSV00036I, respectively, are to appear on the console/JESLOG of the Server Mainframe address space. A value of NO means that DSV00035I and DSV00036I messages are not suppressed and appear on the console/JESLOG (z/OS) and in the SYSPRINT output console. A value of YES means that they are suppressed from the console/JESLOG but are written to the SYSPRINT output file. A value of ALL suppresses ALL messages and nothing is written including any warning or error messages.

Valid Entries: NO, YES, or ALL

Default: NO

 

Also, to issue or modify the SUPMSG option for an active CA Datacom Server, you can issue the console command to modify the option.

Syntax:

/F serverjob,MODIFY OPTION,SUPMSG=value
