2 Installing WebLogic on JRockit VE

This chapter contains the hardware and software requirements for using WebLogic on JRockit VE, and also defines the components in the package.

2.1 Physical Requirements

The following hardware and software are required to configure and run WebLogic on JRockit VE:

2.1.1 Hardware Requirements and Suggestions

Two separate x86 Linux machines:
- Development machine – With an installed WebLogic Server 11g R1 (10.3.2) development platform for all the pre-deployment activities, such as downloading the Zip file package, applying patches, running the Image Tool for CRUD operations on the image, and building applications.
- Deployment machine – That runs in production mode on Oracle VM Server.
Allocate 1024 MB of memory and 1024 MB of disk space for each WebLogic Server virtual machine that will be running on Oracle VM Server.
WebLogic on JRockit VE requires a CPU with PAE support.

2.1.2 Software Requirements

Oracle VM Manager 2.2, deployed as an Oracle VM Manager template on an Oracle VM server.
- For information about the prerequisites for installing Oracle VM Manager and Server, see the Oracle VM Server Installation Guide and the Oracle VM Manager Installation Guide.
- For information about Oracle VM templates, see the Oracle VM Templates page on the Oracle Technology Network.
The Image Tool requires having the Java Runtime Environment (at least JDK version 6) installed on your development Linux machine.
WebLogic Server 11g R1 (10.3.2) on your development Linux machine for building applications, running WLST (online or offline), and running the Administration Console.

2.1.3 Usage Recommendations

The following usage recommendations apply to this release of WebLogic on JRockit VE.

In a virtual machine that is configured with multiple virtual CPUs, in certain circumstances (for example, when there is a lot of synchronization between threads), performance might be affected. To avoid performance bottlenecks, run your WebLogic Server VMs with single virtual processors only.
Avoid intensive file I/O operations.

2.2 Installing the WebLogic on JRockit VE Package

To install WebLogic on JRockit VE, extract the contents of the packaged wlsvePackage.zip file to a directory of your choice on your Linux development machine.
