Dear Hari,

sounds like there is a problem with the message server/dispatcher connection. Check the trace files dev_disp and dev_ms and make sure that the dispatcher is connected to the message server (this can easily be verified by running transaction SM51). Keyword to look for in dev_disp is MBUF. The last entry should be 'MBUF state ACTIVE'. Also check that the message server process (msg_server) is up and running and was able to bind the port. Finally look in the profile for parameters rdisp/enqname and see if that points to the right server and port (which is sapms<SID>).

Regards,

Goto Transaction SM12 --> Extras --> Diagnostics, & you can know the problem.

Check/restart the Enqueue server.

Hi Hari:

It is your Enqueue server up and running on that instance ?

Can you try SM50 is see if ENQ workprocess is OK ?

Also you can check the developer traces for the enqueue.

Hope this helps!
