Server customers. Even without Janus Web Server, it is possible to issue a MSGCTL
command for any message with the AUDITRK parameter. It is then possible to
suppress RK messages from going to the audit trail by making sure the X'20' bit is not
set in SYSOPT. The one unfortunate side-effect of this technique is that it also
suppresses RK messages that one might actually want to go to the audit trail, but this
can be overcome by MSGCTL'ing these messages to NOAUDITRK. Thanks to Warren

Description

This parameter makes it possible to reduce the quantity of audit trail data associated with Janus Web Server applications. The WEBAUDIT parameter is a collection of bits that, when set, reduce the quantity of data sent to the Model 204 journal

or make it possible to reduce this quantity.

The bits in WEBAUDIT are:

X'00000001' Extends NOAUDIT capability, allowing NOAUDITW on the MSGCTL command.
MSGCTL msg_no NOAUDIT Prevents msg_no issued on any thread from going to the audit trail
MSGCTL msg_no NOAUDITW Prevents msg_no issued on a Janus Web Server thread from going to the audit trail

See Usage notes for more information.

X'00000002' Suppress APSY load since-last statistics for Janus Web Server threads.

The resource usage associated with the APSY load such as CPU, DKPRs, disk I/Os, etc. will be included in the EVAL since-last statistics for the request. Since APSY load resource utilization is typically extremely minor relative to request evaluation, APSY load since-last

statistics do not provide much useful information.
X'00000004' Suppress APSY load since-last statistics for all threads. The resource

usage associated with the APSY load such as CPU, DKPRs, disk I/Os, etc. will be included in the EVAL since-last statistics for the request. Since APSY load resource utilization is typically extremely minor relative

to request evaluation, APSY load since-last statistics do not provide much useful information.
X'00000008' Suppress “NO USERID” logout messages (M204.0353) for Janus Web Server threads. These messages are sometimes issued before a user logon, even though there is no user ID logged on the thread, so they are not useful.
X'00000010' Suppress “NO USERID” logout messages (M204.0353) for all threads. These messages are sometimes issued before a user logon, even though there is no user ID logged on the thread, so they are not useful.

Usage notes

Note: The MSGCTL NOAUDIT enhancement should be used with caution. Preventing certain messages from going to the journal could make diagnosing certain problems more difficult.

In any case, the MSGCTL NOAUDIT and NOAUDITW provide a neater and more fine-grained way of reducing audit trail messages for Janus Web Server or other threads. Some good candidates for MSGCTL NOAUDIT or NOAUDITW are:

M204.0099 MINIMUM SERVSIZE FOR THESE TABLES = ...
M204.0131 (Checkpoint completed or timed out messages)
M204.0353 (login/logout message that is essentially a shortened version of M204.0352 that also gets logged to the journal)
M204.0608 FILE CLOSED: ...
M204.0619 GROUP FILE OPENED: ...
M204.0620 FILE file OPENED (-- NO UPDATES ALLOWED)
M204.0621 (Informational message indicating recovery status of file being opened)
M204.0622 (Informational message indicating the last update applied by the last rollforward for a file being opened)
M204.0821 GROUP FILE CLOSED: ...
M204.0858 GROUP group OPENED (-- NO UPDATES ALLOWED)
M204.1203 FILE file WAS LAST UPDATED ON ...
M204.1238 (Informational message indicating the time the file was last recovered.)

The NOAUD parameter on Janus port definitions allows even more information to be suppressed from the audit trail on a port basis.
