Loads of you had been requested, so the thought was to get issues straight.
On this article, I’ll speak about the best way to improve JDK (Java Improvement Equipment). 1.6 Disagreeable 1.7 on Pink Hat Linux or CentOS.
This assumes that you’ve root permission and that JDK 1.6 or earlier is already put in.
- Let’s confirm the Java model put in on the server.
[~] #java -version
java model "1.6.0_24"
OpenJDK Runtime Atmosphere (IcedTea6 1.11.11.90) (rhel-1.62.1.11.11.90.el6_4-x86_64)
OpenJDK 64-Bit Server VM (construct 20.0-b12, combined mode)
[~] #- Obtain JDK 1.7 from Oracle obtain web page and add to the server within the /tmp space
- Set up downloaded JDK1.7 RPM utilizing
rpm –ivhcommand
[/tmp] #rpm -ivh jdk-7u60-linux-x64.rpm

lrwxrwxrwx. 1 root root 16 Jul 1 15:14 default -> /usr/java/newest [/usr/java]
#- Now you’ll be able to set /usr/java/jdk1.7.0_60 to JAVA_HOME surroundings variable to make use of JDK 1.7
- Now let’s confirm the JAVA model.
[~] #java -version
java model "1.7.0_60" Java(TM) SE Runtime Atmosphere (construct 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (construct 24.60-b09, combined mode)
[~] #I hope this quick information helps you improve JDK on a Linux platform.
