------------------------------------

One Way to Test This

I've got a SOA-P 5.3 installation with the roll-up patch installed.

I've got VDB with the TPCR database as a source and a view model which has several tables with transformations based on the TPCR test suite. The idea is to produce a query which runs for several seconds to give me time to switch to RHQ and try the different methods. With all this in place, I execute my query of the table, switch over to RHQ and run both the View VDB Sessions and View VDB Requests actions. (Hopefully all this is done before the query finishes.)

The query I execute is: select * from vTpcr.Q04  ORDER BY o_orderpriority

I tail the server.log file to see if any exceptions were thrown.

> Using RHQ while a long query was executing, I used the VDB's "View VDB Requests" and received no information in the UI. The server log contained the attached exception and stack trace.
> java.lang.reflect.UndeclaredThrowableException: Failed to invoke method 'getRequestsUsingVDB' on component 'RuntimeEngineDeployer' with parameters [SimpleMetaType:java.lang.String:TpcrVdb, SimpleMetaType:int:1].
