Troubleshooting

For a list of common errors in GT, see Error Codes.

1. No triggers displayed in mds-trigger-view

I created a trigger using the mds-trigger-create, but I don't see any triggers when I type mds-trigger-view! Where are the triggers? Why is nothing happening?

Did you set up a trigger registration? (See the Trigger Service Admin Guide) The trigger has been created (unless there was an error), but you will not see it and you cannot access it if the trigger registration has not been set up.

2. Trigger never fires

I'm sure the registration was made properly, but the trigger script never fires. OR I followed all of the above steps, but where are the triggers? Why is nothing happening?

Once you've completed the trigger registration, you can now create individual triggers. Trigger creation is performed using a client. See the User's Guide for more information on clients.

3. Error Messages

Table 1. WS MDS Trigger Service Error Messages

Error CodeDefinitionPossible Solutions
Error ; nested exception is: org.apache.commons.httpclient. NoHttpResponseException: The server xxx.x.x.x failed to respondHappens when trying to create a trigger for the Trigger Service. The above error is accompanied by the following error in container: [JWSCORE-192] Error processing request java.io.IOException: Token length 1347375956 > 33554432. FIXME - what causes this? Be sure that you have properly edited the client-config-settings file under globus_wsrf_mds_trigger. The DefaultServiceAddress parameter should properly reflect the service prefix from your container, e.g.: https://127.0.0.1:8444/wsrf/services/. The services you wish to monitor should also be consistent.
WS MDS is built on Java WS Core, please see Java WS Core Error Codes for more error code documentation.
