Applies To:

Linux OS - Version Oracle Linux 7.0 and later

Goal:

How to update OpenJDK Java version on Oracle Linux 7 or Later

Solution:

• Ensure the yum repository or software source is enable to provide the OpenJDK version.

OL7: [ol7_latest]    or [ol7_latest-x86_64]
OL8: [ol8_appstream] or [ol8_appstream-x86_64]
OL9: [ol9_appstream] or [ol9_appstream-x86_64]

• Install the desired OpenJDK version by running yum(8) or dnf(8). This will automatically cleanup the older version. Here is an example from OL7.

[root@Serverxx~]# yum install java-1.8.0-openjdk.x86_64    ## installs the latest version at that time

OR

[root@Serverxx~]# yum install java-1.8.0-openjdk-1.8.0.382.b05-1.el7_9.x86_64    ## installs that specific version
