Issue/Introduction

Mainframe Datacom Server startup option SUPMSG can be used to monitor the connections to the server, including the task number, user ID, date, and time. There may be a need to monitor the connections to a Datacom Server periodically. The 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

Resolution

In the 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

Note: SUPMSG can NOT be issued or modified as a console command.
