Create separate file systems for working data

 

We can also create separate file systems for your log data (/var/mqm/log) and error files (/var/mqm/errors). If possible, store log files on a different physical disk from the WebSphere MQ queues (/var/mqm).

If you create separate file systems:

• The /var/mqm and /var/mqm/log directories must be on a local file system.

• The /var/mqm/errors directory can be NFS mounted. However, if you choose to NFS-mount /var/mqm/errors, the error logs might be lost if the network fails.

If you are creating separate file systems, allow a minimum of 30 MB of storage for /var/mqm for a server installation and 15 MB of storage for /var/mqm for a client installation. Also allow 20 MB of storage for /var/mqm/log, and 4 MB of storage for /var/mqm/errors for both client and sever installations.

If you want to use individual queues that will hold more than 2 GB of data, you must enable /var/mqm to use large files.

The size of the log file depends on the log settings that you use. The minimum sizes above are for circular logging using the default settings. For further information on log sizes see the WebSphere MQ System Administration Guide.
