Use this task to restrict access to the /var/mqm directories and
log files needed for WebSphere MQ as a JMS provider.
About this task
Note: The /var file system is used to store all the
security logging information for the system, and is used to store the temporary
files for email and printing. Therefore, it is critical that you maintain
free space in /var for these operations and prevent unauthorized access to
the file system. If you do not create a separate file system for messaging
data, and /var fills up, all security logging will be stopped on the system
until some free space is available in /var. Also, email and printing will
no longer be possible until some free space is available in /var.
This
procedure involves steps that you complete at different stages of installing
and using IBM WebSphere Application Server, as described below. The steps
are also described at appropriate points in other tasks, but are collected
here for completeness.
