What is Weblogic Generic Jar Installer ?
If we want to Install WebLogic Server with 64-bit JVM’s on Linux and Solaris or to use WLS on any other supported platforms then we can use WebLogic Generic Jar Installers. This Installer requires that you must already have a JDK (JRE Installation will not be useful…u Must have JDK) installed in your Physical Box already. Even this installers do not include a JVM/JDK.

How to get the Generic Jar Installer?
From the Link: http://www.oracle.com/technetwork/middleware/ias/downloads/wls-main-097127.html In this Link first of all you need to Click on the “Accept License” Radio Button …then only you will see the DownLoad Link becomes active.

Example: you can download WLS10.3.3 Installer by clicking on the following references on this page:
Oracle WebLogic Server 10.3 —-> “Generic: 473 MB File1”

How to Install Generic Jar?
If you want to install the WebLogic in 64 bit mode then u must have 64 bit JDK already installed in your BOX. And u must use the “-d64” option while installing the weblogic using generic installer …othetwise you will face some Library related issues later.

Example: Here make sure that your JDK is 64 bit. Or else you will get “unrecognized java option -d64”
JAVA_HOME/bin/java    -d64    -Xmx1024m   -jar    wls1033_generic.jar

If you want to install the WebLogic in 32 bit mode then u can have either 64 bit JDK or 32 Bit JDK already installed in your BOX. Then u can use the following command WITHOUT using “-d64” option

NOTE: The Windows JDK will not come in Dual Mix Mode …(32 bit and 64 bit together) So for Windows JDK you will not see “-d64”  bit option.  So you will have to make sure that you have a correct JDK of version is 32 bit or 64 bit if you are using WINDOWS.

JAVA_HOME/bin/java    -jar   -Xmx1024m   wls1033_generic.jar

How to Identify the JDK Architecture (32-Bit/64-Bit)?
You can verify which architure of your JVM is (32 bit or 64 bit) using “file” Unix Utility… Move inside the Bin directory of your JDK (JAVA_HOME/bin/) and then run the following command

$ file java
java: ELF 32-bit MSB executable SPARC Version 1, dynamically linked, stripped
