Hi team

We are using debezium server 1.8 version, which is connecting to oracle database(12C enterprise). we are following bellow sequence 

1) Debezium is installed on top of GCP- compute engine machine - e2standard4 
2) Debezium is able to establish the connectivity with oracle db (10.6.63.198)

3) but considering "source.log.mining.archive.log.only.mode=true" property - to read archive logs only, we are getting ORA-01291: missing logfile issues.

4) While running with "source.log.mining.archive.log.only.mode=true" property we are able to get backfill data, but once it starts for streaming , it throws the ORA-01291: missing logfile errors.

observations:

1) If we run with redo+archive i.e  "source.log.mining.archive.log.only.mode=false" property, our debezium CDC pipeline working fine.

2) Caused by: Error : 1291, Position : 0, Sql = BEGIN sys.dbms_logmnr.start_logmnr(startScn => '126133316324', endScn => '126133324126', OPTIONS => DBMS_LOGMNR.DICT_FROM_REDO_LOGS + DBMS_LOGMNR.DDL_DICT_TRACKING  + DBMS_LOGMNR.NO_ROWID_IN_STMT);END;, OriginalSql = BEGIN sys.dbms_logmnr.start_logmnr(startScn => '126133316324', endScn => '126133324126', OPTIONS => DBMS_LOGMNR.DICT_FROM_REDO_LOGS + DBMS_LOGMNR.DDL_DICT_TRACKING  + DBMS_LOGMNR.NO_ROWID_IN_STMT);END;, Error Msg = ORA-01291: missing logfile
ORA-06512: at "SYS.DBMS_LOGMNR", line 58
ORA-06512: at line 1 

As per above error we can see it reads SCN from DICT_FROM_REDO_LOGS (redo log), which is not correct as we are trying to read data from archive logs.

 please help us to resolve issue 

please find the following configuration details
