Rmove OpenJDK
OpenJDK is the default JVM in Oracle Linux. I see quite a lot of posts say simply Run command "yum remove java*", but I'm not sure if this is secure because WILDC ARD is used, so it seems not really. I ' m going to the use of software GUI to remove it. After you login to Oracle linux-->start menu-->system tools-->software, search openjdk then remove packages.

Install Oracle JDK1. Download 64bit JDK archive file2. Extract it into/usr/lib3. ADD java_home variable into/etc/profile. This JVM was enabled for all the users of this VM.
