Java JRockit Installation

Note -- Java JRockit is not standard in java JDK you need to download it from oracle edelivery. A regular java JDK will not work for a peoplesoft installation.

Download Java JRockit
  1. Log in to Oracle Linux as the "weblogic" user 
  2. Navigate to https://edelivery.oracle.com/
  3. Log in to e delivery and select the following:
    1. Product Pack: Peoplesoft Enterprise
    2. Platform: Linux x86-64

  5. Select "Peoplesoft Enterprise- PeopleTools 8.51 Media Pack".
  6. Select "JRockit Mission Control 4.0 for Java SE 6 for Linux x86-64"
  7. Download it to your Desktop and unzip the file.
Installing Java JRockit
  1. Open a Terminal
    • [weblogic@localhost ~]# cd Desktop
    • [weblogic@localhost Desktop]# chmod 777 jrmc-4.0.0-1.6.0-linux-x64.bin
    • [weblogic@localhost Desktop]# ./jrmc-4.0.0-1.6.0-linux-x64.bin
  2. Click the "Next" button.

  4. A warning box will popup. Click the "Yes" button.
  5. Click the "Next" button.
  6. Click the "Done" button.

Editing the Java link to see JRockit
In linux there is a symbolic link that keep track of what linux version to use. We need to edit this symbolic link to point to JRockit.
  1. Open a Terminal
    • [weblogic@localhost ~]#  cd /usr/bin
    • [weblogic@localhost bin]#  ls -al java
    • lrwxrwxrwx 1 root root 22 Jun 1 13:26 java -> /etc/alternatives/java
    •  [oracle@localhost bin]#  su root
    • password: "oracle"
    • [root@localhost bin]# mv java oldjava
    • [root@localhost bin]# ln -s /apps/mdlware/bin/java
    • [root@localhost bin]# ls -al java
    • lrwxrwxrwx 1 root root 22 Jun 2 12:26 java -> /apps/mdlware/bin/java
  2. Check the java version.
    • [root@localhost bin]# java -version
    • Check the image below for the output. You will run into problems when you try to use weblogic. When weblogic installs, it will take the current symbolic link for java and set that value in it's environment varibles. If the link has not been edited correctly, you will recieve errors when trying to run the peoplesoft PIA. It is not fun to fix, because you will need to find the correct files to edit within the weblogic folders. Bottom line, when you type in java -version it should point to Jrockit or problems happen.


Then next step in the peoplesoft Installation is the "Weblogic Install"
