Meridian Link application malfunction

Application registration fails

Meridian Link Release 5C/CCR Release 3C Diagnostic and Maintenance Guide
An application malfunction denotes the failure of the host-based
application. Given that the base Application Module or IPE Module is
operational (UNIX is loaded, application software is running, and both link
0 and
link 1 are up), if the host application does not perform as desired, the
failure is classified as an application failure. The following sections
describe how to treat such failures.
Make sure services expected by the host computer are on the distribution
tape. See tape labels and verify with the host programmer.
1 Application registration can only take place after Meridian Link has
successfully started on the Application Module or IPE Module and the
link between the host and the application (link 1) is up. Verify that the
Host Link is up by logging in as mlusr and typing the following:
mlusr> status link 1
Press [Return]. If the response is ÒLink 1 : UpÓ, the Host Link is up.
Otherwise, refer to ÒX.25 Host Link (link 1) will not establishÓ or
ÒTCP/IP Host Link (link 1) will not establish.Ó
2 If the host link is up, analyze the Application Registration Response
message returned by the application in response to an Application
Registration message sent by the host application.
A message trace of the Host Link can be set up by using the trace
facility on the application. To turn on the trace, log in as mlusr and
type the following:
mlusr> trace link 1
Press [Return]. Have the host application attempt the application
registration. Turn off the trace when the host application has finished
attempting the registration and type the following:
mlusr> untrace link 1
Press [Return]. Use the view command to look at the trace file.
