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)

Alternatively, you can specify this information on the XA open string. See XA Resource Manager Definition for WebSphere MQ for more information.

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