WebSphere MQ-Specific Environment Variables

These environment variables relate to configuring the WebSphere MQ environment. For the most part, you do not need to specify these environment variables, unless you have installed WebSphere MQ in a non-default location, or you are instructed to do so by Micro Focus.

ES_MQ_1PC

Indicates whether the IBM WebSphere MQ switch module ESMQXA should operate in one-phase commit mode. Set this environment variable only when advised to do so by Micro Focus.

ES_MQ_LIB

The full name including the path of the IBM WebSphere MQ client or server library

Important: In AIX environments the library is an object inside a shared object. For example

ES_MQ_LIB="/usr/mqm/lib64/libmqmxa64.a(libmqm64.o)"

ES_MQ_LIB_T

The full name including the path of the IBM WebSphere MQ client or server library, for threaded environments

ES_MQ_LIB_XA

The full name including the path of the IBM WebSphere MQ XA library

Important: In AIX environments the library is an object inside a shared object. For example

ES_MQ_LIB="/usr/mqm/lib64/libmqmxa64.a(libmqm64.o)"

ES_MQ_LIB_XA_T

The full name including the path of the IBM WebSphere MQ XA library, for threaded environments

ES_MQ_LISTENER

Defines one or more WebSphere MQ listeners.

Values

ES_MQ_LISTENER={QueueManagerName,QueueName,ListenerName}
[,QueueManagerName,QueueName,ListenerName]...

ES_MQ_XA

The type of XA structure to use for the two-phase commit XA switch module.

Values

D: use a dynamic XA structure
S: use a static XA structure

MQSERVER

The name of a minimal channel.

Values

MQSERVER=ChannelName/TransportType/MachineName(Port)

where:

ChannelName specifies the name of a channel as defined on the server
TransportType specifies the communications protocol, which can be:
- TCP
- LU62
- NETBIOS
- SPX
MachineName(Port) specifies the name of the server machine and optional port number

Example:

MQSERVER=CHANNEL3/TCP/QServer(1414)

Important: If you have defined MQ as an XA resource, then the values used in this environment variable must also be contained in the XA open string. See XAR for WebSphere MQ for more information.

This environment variable is IBM-defined, and more information may be found in the relevant IBM publication.
