How to Install Java 7(JDK 7u60) On RHEL 6

Step1 Download File
http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
#tar xzf jdk-7u60-linux-x64.gz

Step2 Install JAVA using Alternatives
#cd /home/oracle/alice/jdk1.7.0_60
#[oracle@infbjvm1XX jdk1.7.0_60]$ sudo -i
[root@infbjvm1XX ~]# alternatives --install /usr/bin/java java /home/oracle/alice/jdk1.7.0_60/bin/java 2
[root@infbjvm1XX ~]# alternatives --config java
There are 3 programs which provide 'java'.
  Selection    Command
-----------------------------------------------
*+ 1           /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
   2           /usr/lib/jvm/jre-1.6.0-openjdk.x86_64/bin/java
   3           /home/oracle/alice/jdk1.7.0_60/bin/java
Enter to keep the current selection[+], or type selection number: 3
#

Now you may also required to setup javac and jar commands path using alternatives:
[root@infbjvm1XX ~]# alternatives --install /usr/bin/jar jar /home/oracle/alice/jdk1.7.0_60/bin/java
[root@infbjvm1XX ~]# alternatives --install /usr/bin/javac javac /home/oracle/alice/jdk1.7.0_60/bin/java
[root@infbjvm1XX ~]# set jar /home/oracle/alice/jdk1.7.0_60/bin/java
[root@infbjvm1XX ~]# set javac /home/oracle/alice/jdk1.7.0_60/bin/javac

Step3 Check JAVA Version
# java -version
java version "1.7.0_60"
Java(TM) SE Runtime Environment (build 1.7.0_60-b19)
Java HotSpot(TM) 64-Bit Server VM (build 24.60-b09, mixed mode)

Step4 Setup Environment Variables
export JAVA_HOME=/home/oracle/alice/jdk1.7.0_60/
export JRE_HOME=/home/oracle/alice/jdk1.7.0_60/jre
export PATH=$PATH:/home/oracle/alice/jdk1.7.0_60/bin:/home/oracle/alice/jdk1.7.0_60/jre/bin

Problem starting Weblogic Server 10.3.6

Error info:
<Jun 30, 2014 2:46:15 PM CST> <Critical> <Health> <BEA-310006> <Critical Subsystem PersistentStore._WLS_AdminServer has failed. Setting server state to FAILED.
Reason: weblogic.store.PersistentStoreFatalException: [Store:280105]The persistent file store "_WLS_AdminServer" cannot open file _WLS_ADMINSERVER000000.DAT.>

Workaround:
Navigating to
/user_projects/domains/<<Domain_name>>/servers/AdminServer/data/store/default/

directory and delete the _WLS_ADMINSERVER000000.DAT file.
After deleting the file, try restart the server again.
This action is detailed out in Oracle Support doc if 957377.1.

Work around:
The reference bug is listed following:
http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4957990

In my case the solution was to edit the DOMAIN\bin\setDomainEnv.cmd file. The following modifications were made before the server would start as intended:

The -Xms and -Xmx values were increased;
the -XX:PermSize and -XX:MaxPermSize values were increased too
and lastly, but probably most importantly
the if "%JAVA_VENDOR%"=="Sun" (conditions were changed to if "%JAVA_VENDOR%"=="Oracle" ) in order to properly recognize my JVM.
