An odd circumstance here, which crosses into Forms territory a bit.
Specifically, a 12c Reports inprocess server has been used in the past for executing run_report_object from Forms. This inprocess-server-using request succeeds, and Forms moves on to other things. However, when a standalone server is used for the report_object's REPORT_SERVER instead of the inprocess server, the result is a 41214.
Some further background:
The host running the servers goes through this process when firing up - start Node Manager, start OHS, start WebLogic, start WLS_FORMS, start WLS_REPORTS, start standalone server, start inprocess server (the last two sometimes happen in opposite order).
The run_report_object's report_object parameter has properties REPORT_DESTYPE=CACHE, REPORT_COMM_MODE=1, and REPORT_OTHER='RECURSIVE_LOAD=NO'.
While it does not SEEM to affect the server's execution or lack thereof, the Reports server on the specified host has port 9002, while both OHS and Forms have port 7777.
Might anybody recognize this scenario?
