Create an Oracle data source using OCI

Last modified: 15 May 2024

PyCharm uses JDBC drivers to connect to the Oracle server through the TNS protocol. The following driver modes are available:

  • In Thin mode, the JDBC driver always connects to the TNS listener. In this mode, various versions of the JDBC driver can be used.

  • In OCI mode, the JDBC driver uses native libraries. In this case, the JDBC driver's version must be the same as the version of these native libraries.
