RAC error on non-RAC instance for weblogic.application.ModuleException: oracle.ons.NoServersAvailabl
During installation of OTM application, we encountered the error:
This Exception occurred at Mon Jul 17 15:48:21 CDT 2018.
weblogic.application.ModuleException: oracle.ons.NoServersAvailable: Subscription time out
MDSConfig.py script completed: 1
when we look at Oracle documents, it says this issue could occur wen installing OTM on a RAC database when the ONS port has not been opened (doc 2424354.1). However, we are NOT running a RAC. We do however, run Oracle GRID with ASM on all our databases.
When I checked the portlist.ini, it is empty, so I take that as no one has overwritten the default ports 6100 and 6200 for the ONS. So why does the installer fail on this error? Any thoughts or similar encounters?
