Diagnosing reporting environment problems
Use the Ping request to test whether a specific component of the reporting environment is operational and to retrieve other information. A Ping request must specify a destination. Using the Information Delivery API, you can test the following destinations:
The Message Distribution service (MDS)
A BIRT iHub node running the Encyclopedia engine (EE)
A BIRT iHub node running the Factory service (FS)
A BIRT iHub node running the View service (VS)
An Actuate open server driver (OSD)
A connection to a data source
If a destination is not operational, BIRT iHub returns an error message. If a destination is operational, the response depends on the Ping request you send. For example, you can request a simple timestamp that shows the elapsed time between when a component receives the request and when it sends a reply. You also can request more detailed information.
A Ping request to the MDS has no security restrictions. For all other components, the request is subject to Encyclopedia volume authentication. The user must be an Encyclopedia volume administrator or a user in the Operator security role.
