Before you install WebSphere® MQ for HP-UX,
create and mount a file system called /var/mqm. If possible,
use a partition strategy with a separate volume for the 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.
