Poor Performance with the JDBC 19c Drivers when Doing Batch Updates (Doc ID 2846521.1)

Last updated on AUGUST 09, 2023

Applies to:

JDBC - Version 19.3 and later
Information in this document applies to any platform.

Symptoms

Performance of INSERT using a JDBC application is much slower using the JDBC 19c driver (ojdbc8.jar) than when using the JDBC 12.1.0.2 driver (ojdbc7.jar).
The tests are using the same database 19c.

The difference in performance between the JDBC 12.1.0.2 and the various JDBC 19c tried is very significant and involves a very large increase in network traffic.
