Defining the WebSphere MQ local NetBIOS name

 

The local NetBIOS name used by WebSphere MQ channel processes can be specified in three ways. In order of precedence they are:

1. The value specified in the -l parameter of the RUNMQLSR command, for example:

         RUNMQLSR -t NETBIOS -l my_station

2. The MQNAME environment variable whose value is established by the command:

         SET MQNAME=my_station

   We can set the MQNAME value for each process. Alternatively, you may set it at a system level in the Windows registry.

   If you are using a NetBIOS implementation that requires unique names, issue a SET MQNAME command in each window in which a WebSphere MQ process is started. The MQNAME value is arbitrary but it must be unique for each process.

3. The NETBIOS stanza in the queue manager configuration file qm.ini or in the Windows registry. For example:

         NETBIOS:
    
           LocalName=my_station

1. Due to the variations in implementation of the NetBIOS products supported, you are advised to make each NetBIOS name unique in the network. If you do not, unpredictable results may occur. If you have problems establishing a NetBIOS channel and there are error messages in the queue-manager error log showing a NetBIOS return code of X'15', review your use of NetBIOS names.

2. On Windows we cannot use your machine name as the NetBIOS name because Windows already uses it.

3. Sender channel initiation requires that a NetBIOS name be specified either via the MQNAME environment variable or the LocalName in the qm.ini file or in the Windows registry.
