Switching from server-based to client-based messaging

You can switch from server-based messaging, the default method for messaging, to client-based messaging.


  • When you switch to client-based messaging, the database server and IBM® WebSphere® MQ (WMQ) must be installed on the same computer.
  • On Windows, you must have the MKS Toolkit to run the chown command.
To switch to server-based messaging:
  1. Bring down the database server.
  2. Run this command: cd $INFORMIXDIR/extend/mqblade.2.0
  3. Run this command: rm idsmq.bld
  4. Run either of the following commands:
    • cp idsmqc.bld idsmq.bld
    • ln –s idsmqc.bld idsmq.bld

    Note that these commands differ slightly from the commands used to switch to server-based messaging.

  5. Run this command: chown Informix:Informix idsmq.bld
  6. Run this command: chmod –w idsmq.bld
  7. Start the database server.
