Last updated on OCTOBER 04, 2016

Applies to:

Oracle Discoverer - Version 4.1.48.06 to 10.1.2.3 [Release 4.1 to 10.1.2]
Oracle Applications Technology Stack - Version 11.5.8 to 12.0.6 [Release 11.5 to 12.0]
Information in this document applies to any platform.
All Discoverer 4i workbooks run from any menu in any version of e-Business Suite.
***Checked for relevance on 15-Dec-2012***

Goal

When the user opens any Discoverer workbook in an e-Business Suite environment, it can take up to 5 minutes to open. Sometimes the workbook fails after that time, in which case the following error message is displayed : 


"Unable to connect to the Oracle Discoverer Application Server:
Wide Are network connection failed, failed to connect to locator."

The same reports may work fine in another instance and always work fine from Discoverer standalone, using the same Discoverer server, username and responsibility. 

-- Steps To Reproduce:
1. Log into e-Business Suite.
2. Run any of the problem workbooks.
3. The error message is displayed, or the workbook opens after about 5 minutes, when it should take only a few seconds.
