2018-05-18T13:58:09 [SOURCE_CAPTURE ]E: Minimal database supplemental logging level is not enabled [1020418] (oracle_endpoint_imp.c:1009)

You have not set the level Minimal Supplemental Logging for database level. You need run sql as sysdba for set Minimal Supplemental Logging.

[oracle@db-03 ~]$ sqlplus / as sysdba
