IBM GC34-5557-00 manual Installing on AIX, Before Installation, v /var/mqm v /var/mqm/log

Installing on AIX

The MQSeries client is installed into the /usr/mqm directory. This cannot be changed. However, if you do not have enough space in the /usr/mqm file system, follow the procedure given in ªCreating Another File System for the Clientº on page 59.

If you have a previous version of the MQSeries for AIX client installed on your system, or if a file system remains from a previous AIX client installation, see ªMigrating from an Earlier Version of MQSeries for AIXº on page 62.

If you plan to install an MQSeries client and server on the same machine, see ªInstalling MQSeries Clients on the Same Machine as the Serverº on page 57.

Before Installation

Before you can install the MQSeries client on your AIX system you are advised to create and mount a /var/mqm file system, or /var/mqm, /var/mqm/log, and /var/mqm/errors file systems.

If you create separate partitions, the following directories must be on a local file system:

v/var/mqm

v/var/mqm/log

You can choose to NFS mount the /var/mqm/errors directory to conserve space on your local system.

A user ID with the name mqm, whose primary group is mqm, is automatically created during installation. You can create the user and group IDs yourself (see ªCreating the mqm User ID and Groupº on page 59), but make sure you do this before installing the client. User ID and group must both be mqm.

For stand-alone machines, you can create the new user and group IDs locally. For machines administered in a network information services (NIS) domain, you can create the user and group IDs on the NIS master server machine.

After installation, the mqm user ID owns the directories and files that contain the resources associated with the product. This group and user must be defined for any machine on which the MQSeries software is to be installed, whether the machine is a client or a server machine.
