When switching the Oracle DB, a subsequent connection establishment message is perceived:
U00003590 UCUDB - DB error: 'OCIStmtExecute', 'ERROR', '', 'ORA-25412: Transaction playback activated by calling OCIStmtPrepare'
According to Oracle:
Instruction Function APIs
The following function is obsolete as of Oracle 12c Release 2 (126.96.36.199): OCIStmtPrepare ().
Oracle strongly recommends using OCIStmtPrepare2 () in all OCI applications instead of the deprecated OCIStmtPrepare () call.
Use the OCIStmtPrepare2 () call to support the use of application continuity in an HA infrastructure. Applications using OCIStmtPrepare () return the following error: Error - ORA-25412: Transaction replay disabled by calling OCIStmtPrepare.
Steps to reproduce:
Release : 12.3
Component : AUTOMATION ENGINE
the bug was found and will be fixed in a future service pack.
