The problem seems to be syntax error of the Oracle query.
1.) Can you do the following in your oracle database and provide the output.
select TO_TIMESTAMP("01.01.1600:00:00","DD.MM.YYHH24:MI:SS") from dual;
2) What is the data type of the oracle column "RECORD_CREATED_DT" ?
The good example of using TO_TIMESTAMP format is like the below one. I don't know if this format is acceptable in your NIFI processing.
SELECT TO_TIMESTAMP ('10-Sep-02 14:10:10.123000', 'DD-Mon-RR HH24:MI:SS.FF')
3) You can also try the following directly in oracle,
SELECT COL1, COL2 FROM DB1.TABLE1
WHERE TO_TIMESTAMP(RECORD_CREATED_DT ,"DD.MM.YY HH24:MI:SS") >= TO_TIMESTAMP("01.01.16 00:00:00","DD.MM.YY HH24:MI:SS");
