Might need to use Tunneling with Discoverer 11g

Thu, 2015-03-19 13:40
I have noticed a few instances recently of Discoverer 11g Plus failing to open or taking an awful long time to open. In both of the cases where this has been reported to me by my clients, changing the plus communication protocol from Default to Tunneling did the trick.

To enable tunneling for use with Discoverer Plus, use this workflow:

  1. Launch Enterprise Manager using something like: http://server.domain.com:7002/em
  2. Enter your Username and Password. Username is typically Weblogic
  3. Under Farm, on left-hand side, expand Discoverer and Discoverer(11.1.1.x.0)
  4. In the Components window, highlight Discoverer Plus then click the Configure button
  5. In the Communication Protocols window, click the Tunneling radio button (see below)
  6. Click the Apply button
  7. Shut Down the Discoverer service from the top link by clicking on Discoverer | Control | Shut Down - confirm the action
  8. Restart the Discoverer service from the top link by clicking on Discoverer | Control | Start Up - confirm the action (sometimes you have to do this twice)
