MQ library structure

 

Installation of WebSphere MQ for iSeries™ creates the following libraries.

QMQM

The WebSphere MQ base product library.
QMQMSAMP

The WebSphere MQ samples library (if you choose to install the samples). Further samples are put in the IFS root file system, see IFS root file system for MQ server.
QMxxxx library

Each time that you create a queue manager, WebSphere MQ automatically creates an associated library, with a name like QMxxxx where xxxx is derived from the queue manager name. This library contains objects specific to the queue manager, including journals and associated receivers. By default the name of this library is derived from the name of the queue manager prefixed with the characters QM. For example, for a queue manager called TEST, the library would be called QMTEST.

When you create a queue manager, you can specify the name of its library if you want to. For example:

CRTMQM MQMNAME(TEST) MQMLIB(TESTLIB)

You can use the WRKLIB command to list all the libraries that WebSphere MQ for iSeries has created. Against the queue manager libraries, you will see the text QMGR: QMGRNAME. The format of the command is:

WRKLIB LIB(QM*)

These queue manager-associated libraries are retained when the product is deleted.
