Controlling archiving and logging

Many aspects of archiving and logging are controlled by parameters set using the CSQ6LOGP, CSQ6ARVP and CSQ6SYSP macros of the system parameter module when the queue manager is customized. See the WebSphere MQ for z/OS System Setup Guide for details of these macros.

Some of these parameters can be changed while a queue manager is running using the WebSphere MQ MQSC SET LOG, SET SYSTEM and SET ARCHIVE commands. They are shown in Table 4:

Table 4. Archiving and logging parameters that can be changed while a queue manager is running

SET command	Parameters
LOG	WRTHRSH, MAXARCH, DEALLCT, MAXRTU
ARCHIVE	All
SYSTEM	LOGLOAD

We can display the settings of all the parameters using the MQSC DISPLAY LOG, DISPLAY ARCHIVE and DISPLAY SYSTEM commands. These commands also show status information about archiving and logging.

These commands are described in WebSphere MQ Script (MQSC) Command Reference.
