OCI-17380
Replay is disabled because of an open transaction in the Initialization callback
Cause
The connection initialization callback during replay attempt leaves a local transaction opened, before returning. This is prohibited by Application Continuity and will disable replay. The callback can be a connection initialization callback or labeling callback registered on Oracle JDBC data sources, or on an Oracle connection pool, such as Universal Connection Pool (UCP).
Action
Check callback implementation in application to always resolve any active local transaction (i.e., commit or rollback), before callback completion.
