Coming back to a post from 2019:
ORA-24550: signal received: Unhandled exception: Code=e0434352 Flags=1
The message doesnt help that much and hides the error message generated by the application. The message seems to be part of some kind of diagnostics which is enabled by default in some circumstances in Oracle client. It can be turned off by adding the following setting to sqlnet.ora
DIAG_SIGHANDLER_ENABLED=FALSE
After turning it off I got a more helpful error stack trace:
Unhandled Exception: GEONIS.Core.ErrorHandling.GTranslateableException: Could not open Table [VMG.VMG_V_VER_FLA_ART] ---> System.Runtime.InteropServices.COMException: DBMS-Tabelle nicht gefunden [ORA-24372: Ungültiges Objekt für Beschreibung]
