Oracle 19c compatibility with jdk7

Question

I would like to know if oracle 19c is compatible with jdk 7.

I have found out 2 drivers for oracle 19c

• ojdbc8 : for jdk8, jdk9 and jdk11
• ojdbc10 : for jdk10 and jdk11

I would like to know if there is a way to have oracle 19c with a jdk7, and if yes what is the driver that will allow to do it ?

Solution

According to the Oracle JDBC FAQ (Question "What are the Oracle JDBC releases Vs JDK versions?"), only the Java versions you listed (Java 8 to 11) are supported for Oracle 19c.

• I expect that support for later Java versions will be added in the future.
• Java 9 and Java 10 were short-life releases, and are both end-of-life.

As a comment notes, Java 7 has been "end of life" since April 2015. It would be counter-productive for Oracle to encourage continued use of Java 7 by supporting it with new JDBC drivers for new Oracle database releases.

Note that the Oracle drivers are proprietary and source code is not available. So back-porting one of the Oracle 19c compatible drivers to Java 7 is not an option.

You may be able to identify a 3rd-party vendor who will provide (probably sell) you a driver that works. The best I could come up with is this old page that lists vendors:

In summary: If you want to use Oracle 19c with Oracle supported drivers, upgrading to Java 8 LTS or later is the only feasible solution. Upgrading to Java 11 LTS is advisable:

• Oracle Java 8 LTS free public updates (for commercial users) have ended, and Premium Support is due to end in March 2022; see the Oracle Java SE Support Roadmap.

• You can still get free public Java 8 LTS updates from 3rd-party vendors post 2020; see Java is Still Free for all of the details.

What errors do you get when you try this?

Java 7 reached End of Life five years ago, I would be very surprised if Oracle have invested any time at all in building driver support for it.

You can try to use the JDBC driver for Oracle 11.2.0.4 which is still available on the Oracle download page and can be used with Java 7.
