System Management Release Notes

5.7 Lock Manager

Because of this change to nonpaged pool, Compaq recommends the following

steps:

• Use AUTOGEN with feedback information to tune the size of nonpaged pool.

• Inspect MODPARAMS.DAT to check for any NPAGEDYN or NPAGEVIR

settings previously made to increase the size of nonpaged pool due to the lock

manager’s usage.

You may ﬁnd that these parameters can be either trimmed back or removed

due to changes to the lock manager.

The SHOW MEMORY documentation in the OpenVMS DCL Dictionary: N–Z

describes the memory associated with the lock manager.

5.8 OPCOM

This section contains release notes pertaining to the Operator Communication

Manager (OPCOM).

5.8.1 OPCOM Messages Changed (Alpha Only)

V7.2

In OpenVMS Alpha Version 7.2 and later, OPCOM messages from the job

controller and the queue manager now display SYSTEM as the user process. For

example:

%%%%%%%%%%% OPCOM 16-NOV-2000 15:07:49.33 %%%%%%%%%%%

Message from user SYSTEM on NODEX

%JBC-E-FAILCREPRC, job controller could not create a process

%%%%%%%%%%% OPCOM 16-NOV-2000 15:07:49.34 %%%%%%%%%%%

(from node BENN at 16-NOV-2000 15:07:49.34)

Message from user SYSTEM on NODEX

-QMAN-I-QUEAUTOOFF, queue NODEX$BATCH is now autostart inactive

The examples in the OpenVMS System Manager’s Manual do not currently reﬂect

this change.

5.8.2 Handling of Invalid Operator Classes

V7.3

Previously, if the OPC$OPA0_CLASSES or OPC$LOGFILE_CLASSES logicals

contained an invalid class, it would cause OPCOM to signal the error and run

down the process.

This problem has been corrected in OpenVMS Version 7.3.

The following two messages have been added to OPCOM:

%%%%%%%%%%% OPCOM 18-MAY-2000 13:28:33.12 %%%%%%%%%%%

"BADCLASS" is not a valid class name in OPC$LOGFILE_CLASSES

%%%%%%%%%%% OPCOM 18-MAY-2000 13:28:33.12 %%%%%%%%%%%

"BADCLASS" is not a valid class name in OPC$OPA0_CLASSES

If an invalid class name is speciﬁed in either of the logicals, the appropriate error

message is displayed. These messages are displayed on the console at system

startup and logged to the OPERATOR.LOG.

The list of all operator classes is:
