What did I do wrong?
Running on centOS 6.x
Solution :
Try downloading the JDK in “tar.gz”.
Extract the content of your tar.gz to a folder in which you want to have your java installation, example:
tar xvf myJava7.tar.gz
Then, set your JAVA_HOME variable and update the references, to update your references, please do the following:
sudo update-alternatives --install "/usr/bin/javac" "javac" "/path/where/i/extracted/usr/lib/jvm/java7/bin/javac" 1
sudo update-alternatives --config javac
It is better when you use your tar files, you can specify and make your installation of Java or any other component more flexible.
Best regards.
You’re trying to allocate more memory to the Java VM’s heap than you have available. Look at the shell script and see what the arguments are that are being passed to Java.
The arguments to look for are:
- -Xms – minimum
- -Xmx – maximum
You should run the JVM with:
-XX:MaxHeapSize=256m -Xmx512m
You can change both numbers at will, but do make sure that the heap size is large.
[root@centos57 ~]# echo $JAVA_HOME
/java/jdk1.7.0_11
Also run:
java -version
to see what’s installed.
A similar output is what you should see – if not, it isn’t recognizing the JDK as being referenced. Also if the _13 is shown before the _15 you need to move the order.
If all of that fails run:
yum remove java
and reinstall.
