Directory content

Lists the location and content of IBM® MQ directories.

An IBM MQ configuration has three main sets of files and directories:

Executable, and other read-only files that are only updated when maintenance is applied. For example:
- The readme file
- The IBM MQ Explorer plug-in and help files
- License files
These files are described in Table 1.
Potentially modifiable files and directories that are not specific to a particular queue manager. These files and directories are described in Table 2.
Files and directories that are specific to each queue manager on a server. These files and directories are described in Table 3.

Resource directories and files

The resource directories and files contain all the executable code and resources to run a queue manager. The variable, FilePath, in the installation specific IBM MQ configuration registry key, contains the path to the resource directories.

Table 1. Directories and files in the `FilePath` directory
File path	Contents
`FilePath`\bin	Commands and DLLs
`FilePath`\bin64	Commands and DLLs (64 bit)
`FilePath`\conv	Data conversion tables
`FilePath`\doc	Wizard help files
`FilePath`\MQExplorer	Explorer and Explorer help Eclipse plug-ins
`FilePath`\gskit8	Global security kit
`FilePath`\java	Java resources, including JRE
`FilePath`\licenses	License information
`FilePath`\Non_IBM_License	License information
`FilePath`\properties	Used internally
`FilePath`\Tivoli	Used internally
`FilePath`\tools	Development resources and samples
`FilePath`\Uninst	Used internally
`FilePath`\README.TXT	Readme file

Directories not specific to a queue manager

Some directories contain files, such as trace files and error logs, that are not specific to a specific queue manager. The DefaultPrefix variable contains the path to these directories. DefaultPrefix is part of the AllQueueManagers stanza.

Table 2. Directories and files in `DefaultPrefix` directory
File path	Contents
`DefaultPrefix`\Config	Used internally
`DefaultPrefix`\conv	ccsid.tbl data conversion control file, described in Data conversion
`DefaultPrefix`\errors	Non queue manager error logs, AMQERR `nn`.LOG
`DefaultPrefix`\exits	Channel exit programs
`DefaultPrefix`\exits64	Channel exit programs (64 bit)
`DefaultPrefix`\ipc	Not used
`DefaultPrefix`\Qmgrs	Described in Table 3
`DefaultPrefix`\trace	Trace files
`DefaultPrefix`\amqmjpse.txt	Used internally

Queue manager directories

When you create a queue manager, a new set of directories, specific to the queue manager, is created.

If you create a queue manager with the -md filepath parameter, the path is stored in the DataPath variable in the queue manager stanza of the mqs.ini file. If you create a queue manager without setting the -md filepath parameter, the queue manager directories are created in the path stored in DefaultPrefix, and the path is copied into the Prefix variable in the queue manager stanza of the mqs.ini file.

Table 3. Directories and files in `DataPath` and `Prefix`/Qmgrs/`QmgrName` directories
