Set up the WebSphere MQ environment

Note:

This step is not necessary when using WebSphere MQ classes for .NET in server bindings mode. In that case, go directly to Connecting to a queue manager. Before you use the client connection to connect to a queue manager, set up the MQEnvironment.

The C based WebSphere MQ clients rely on environment variables to control the behavior of the MQCONN call. The .NET programming interface allows you to use the NMQ_MQ_LIB

customization value

but also includes a class MQEnvironment. This class allows you to specify the following details that are to be used during the connection attempt:

• Channel name

• FIPS required

  

• Header compression

  

• Host name

• Key reset count

  

• Message exit

  

• Authentication information record array

  

• Message data compression

  

• Password

  

• Port number

• Receive exit

  

• Receive user data

  

• Security exit

  

• Security user data

  

• Send exits

  

• Send user data

  

• SSL cipher specification

• SSL cryptographic hardware

• SSL key repository

• SSL peer name

• User ID

  

To specify the channel name and host name, use the following code:

MQEnvironment.Hostname = "host.domain.com";
MQEnvironment.Channel  = "client.channel";

By default, the clients attempt to connect to a WebSphere MQ listener at port 1414. To specify a different port, use the code:

MQEnvironment.Port = nnnn;
