Create a file system for the working data

 

Before you install WebSphere MQ for Linux, create and mount a file system called /var/mqm. If possible, use a partition strategy with a separate volume for the WebSphere MQ data. This means that other system activity is not affected if a large amount of WebSphere MQ work builds up.

To determine the size of the /var/mqm file system for a server installation, consider:

• The maximum number of messages in the system at one time

• Contingency for message buildups, if there is a system problem

• The average size of the message data, plus 500 bytes for the message header

• The number of queues

• The size of log files and error messages

• The amount of SSL trace that is written to the /var/mqm/trace directory

Allow 50 MB as a minimum for a WebSphere MQ server and 15 MB as a minimum for a WebSphere MQ client.
