Oracle 9i Source Connector Library


What library does Oracle DB Source connector use? Is it a JDBC one? or Oracle’s instantclient?

If so, is there a way to replace the Oracle’s DB Source Connector library and use an older version so we can connect to legacy Oracle 9i Database to migrate our data?

The libraries that are used and work to connect to Oracle 9i is Oracle instantclient 11.2 version or the JDBC same version.
