Temporarily disabling the hardcopy medium

If you are using SYSLOG as the hardcopy medium and it is not operating properly, MVS™ saves the messages in log buffers until their number reaches the value of LOGLIM. When this limit is reached, messages are held until there is no storage available for them. At this point, no new messages can be displayed; the only way to re-start the log is to de-activate it. This requires a re-IPL.

A parameter is available to turn off hardcopy. The parameter, UNCOND, is coded on the VARY command. For example:

VARY SYSLOG,HARDCPY,OFF,UNCOND

After this command is executed, you can remove SYSLOG as the hardcopy medium, and WRITELOG CLOSE is accepted.

Note: This should be a temporary measure because, if SYSLOG has been removed the system can lose messages from hardcopy.

If SYSLOG is removed and it was the only hardcopy medium, it is considered temporarily off. Log buffers can be saved only until they reach LOGLIM. After this point some messages can be lost, but the outage will be prevented.
