we have 2 types of Logfiles in MQ.

1. Error logs.

these logs can be found under

/var/mqm/qmgrs/<QMGRNAME>/errors and the log files starts

with AMQERR01.LOG/AMQERR02.LOG/AMQERR03.LOG. These logs are

used to capture error logs to that particular logs.

/var/mqm/errors. Unthis DIR again you see same files. This

will capture errror logs related to all QMGRS in the server.

2. Transacational(ACTIVE) logs.

These logs are used for media recovery and restat recovery.

Location:/var/mqm/log/QMGR/active. File names starts with S.

Space to these files are allocated based on your settings in

qm.ini file.

This we call as logspace.
