Hello,
The errors you are receiving are typically a result of not following our published MOS note and our documentation. It’s important in order for Oracle E-Business Suite systems to be properly recognized by E-Business Suite Plug-in, AutoConfig must be enabled and updated on all nodes. You should prevalidate your system before the running discovery to help ensure success of the discovery process. These tests check that context files, context variables, users, and components are set up correctly in the system for successful discovery.
For more information on both topics refer to:
•     Getting Started with Oracle Application Management Pack (AMP) for Oracle E-Business Suite, Release 12.1.0.1 (Doc ID 1434392.1)
•     Oracle Application Management Pack for Oracle E-Business Suite Guide Release 12.1.0.1.0 Part No. E28715-03 October
If you are still experiencing errors after reviewing our documentation and taking the appropriate steps to prevalidate your system consider filing a Service Request with Support.
