The core uncertainty was whether the arguments passed to the top-level cargo invocation act as a global configuration for the … Read more
Summary A critical failure occurred during the execution of a complex metadata extraction query on Oracle 19.26. The system threw an ORA-01858 error: “a non-numeric character was found where a numeric was expected”.

This postmortem explores the discrepancy between GUI-driven metadata … Read more
