Is there a problem with the network?

IBM® Integration Bus uses WebSphere® MQ for inter-component communication. If components are on separate queue managers, they are connected by message channels.

About this task

Communication problems can arise between any of these resources:

Procedure

  • integration nodes
  • The IBM Integration Toolkit

What to do next

If any two components are on different queue managers, make sure that the channels between them are working. Use the WebSphere MQ display chstatus command to see if messages are flowing.

Use the ping command to check that the remote computers are connected to the network, or if you suspect that the problem might be with the network itself. For example, use the command ping integrationNodeName, where integrationNodeName is a computer name. If you get a reply, the computer is connected. If you don't get a reply, ask your network administrator to investigate the problem. Further evidence of network problems might be messages building up on the transmission queues.
