ReadonlycodeReadonlycontextReadonlydeadlineA PL/SQL RAISE_APPLICATION_ERROR (ORA-20000 to ORA-20999): its number
and message, without the ORA-20xxx: prefix and the ORA-06512 stack
lines. Its code is CONFLICT (409), and the message is for the client.
The database's or the driver's code: 'ORA-00001', 'NJS-040', 'NJS-123'…
The ORA error number of the failure, if the database reported one.
Whether web-kit shows the message to the client: a PL/SQL application error's.
The statement ran out of time: node-oracledb's callTimeout (NJS-123) or the driver's deadline.
node-oracledb did not answer a call within its deadline (its timeout plus
deadlineGrace): the driver stopped waiting and dropped the connection without waiting for the call. A transaction on that connection is lost.
