ORA-01346
Oracle LogMiner processed redo beyond primary reset log SCN string
Cause
Oracle LogMiner detected a new branch with reset log SCN information prior to redo already mined.
Action
If running inside SQL Apply, retrieve standby reset SCN by executing DBMS_LOGSTDBY.MAP_PRIMARY_SCN (primary reset log SCN). And, execute FLASHBACK STANDBY DATABASE [<database_name>] TO BEFORE SCN standby reset SCN. Note: If the primary reset log SCN is 0, then intermediary log files are missing. Check the primary database for missing log files.
In other scenarios, contact Oracle Support Services.
