View source for OPCOM

'''OPCOM''', or the Operator Communication Manager, is a tool for communicating with users and operators on an OpenVMS system. It displays messages and events on terminals designated as operator terminals and writes them to a log file.

=Event Classes=
The following event classes can be enabled for OPCOM:
* CENTRAL
* PRINTER
* TAPES
* DISKS
* CARDS
* NETWORK
* SECURITY
* LICENSE
* OPER1 through OPER12

=Related Logicals=
* OPC$OPA0_ENABLE enables or disables [[OPA0:]] as the operator terminal by default
* OPC$OPA0_CLASSES specifies the classes enabled for OPCOM on OPA0:
* OPC$LOGFILE_NAME specifies the location of the log file
* OPC$LOGFILE_ENABLE enables the creation of OPERATOR.LOG
* OPC$ALLOW_INBOUND enables the inbound traffic from a node
* OPC$ALLOW_OUTBOUND enables the outbound traffic to a node

=Commands=
REPLY/LOG enables a terminal as an operator and opens a new version of [[OPERATOR.LOG]]
REPLY/ENABLE enables a terminal as an operator for the classes specified as keywords
REPLY/DISABLE disables a terminal as an operator for the classes specified as keywords

=Privileges=
Using OPCOM requires the following privileges:
* [[OPER]] to enable or disable the operator terminal (for all classes of events)
* [[SHARE]] to log into the designated operator's terminal as another process
* [[SECURITY]] to enable or disable sercurity events in the terminal
* none to send messages to an operator

=Operator Log=
By default, the operator log is stored in SYS$MANAGER:OPERATOR.LOG. The logfile is created if OPC$LOGFILE_ENABLE is defined as "TRUE" every time the system is rebooted. The classes are taken from OPC$LOGFILE_CLASSES or, if a log file is already open, from the current log file. If the logical does not exist, all classes are enabled. If OPC$LOGFILE_CLASSES contains an invalid class, all classes are enabled. In a clustered environment, this file is node specific.
Messages that get into the log file can be controlled with REPLY/LOG/ENABLE and REPLY/LOG/DISABLE. Generally, messages that are logged to OPA0: also go to the operator log except the following:

* System SECURITY alarms and audits enabled using SET AUDIT command. These SECURITY messages are either logged to operator terminal and/or to [[SECURITY.AUDIT$JOURNAL|SYS$COMMON:[SYSMGR]SECURITY.AUDIT$JOURNAL]].
* Messages generated by the [[LANACP]] LAN Server process when a device status changes. These messages are displayed on the operator terminal and included in the log file written by LANACP, SYS$MANAGER:LAN$ACP.LOG.
