OVERVIEW
The release of the alpha version 1.1.6 of the IBM Developer Kit continues IBM's strong commitment to the Linux and Java platforms and communities. The Developer Kit is IBM's port of Sun's JDK(TM) 1.1.6 to the Linux operating system running on Intel architecture based computers. The Developer Kit includes similar IBM Just-In-Time (JIT) compiling technology found in IBM's high performing, industry-leading Developer Kits for the OS/2 and Windows** operating systems.

This is still an alpha version of the Developer Kit so we need your help to improve and refine it. Once you have downloaded and tested the IBM Linux Developer Kit, please post your feedback on this technology to our discussion forums.
FAQ

  1. On what Linux systems can I run the IBM Developer Kit?

    We have run it on:

    Caldera Open Linux 2.2
    Pacific Hi Tech TurboLinux 3.6
    RedHat Linux 6.0
    SuSE Linux 6.1

    Our expectation is this code will run on other Linux« products that include the code requirements below. We welcome your comments on our alphaWorks discussion forum to help us determine the other Linux distributions that run well with our alpha code.

    This port requires:

    1. Linux kernel 2.2 (all Linux distributions above contain the 2.2 kernel). For information on upgrading your system with a 2.2.x level Linux kernel please see: http://www.kernel.org

    2. glibc 2.1 (Which ships with RedHat 6.0 and Caldera 2.2). You may also download glibc 2.1 from the ftp site at glibc.cygnus.com/pub/glibc


  2. Why did you develop a Java 1.1.6 version Developer Kit?

    Our goal was to get a high performance developer kit in your hands as quickly as possible. Using our 1.1.6 AIX port as a base provided us with an effective way to achieve that objective. Similarly, IBM's 1.1.6 JIT for Intel is proven technology that provided a solid starting point for porting to Linux.

  3. What kind of performance do you see with this code.

    Our limited testing experience on the Linux platform indicates the code performs well. Please share your performance experience with this code on our discussion forum by clicking on the "discussion button"

  4. What are the system requirements?

    Computer: Intel 486 or better (Pentium recommended) Platform: Linux Disk Space: 9MB (to download) 30MB (to uncompress), Memory: 32MB RAM Display: Suitable for X-Window usage Dependencies: Linux kernel 2.2, glibc 2.1.

  5. Where can I go for additional information on this alpha code?

    You can access our discussion forum that has been established to collect your suggestions and ideas by clicking on the "discussion button" at this site.

  6. What Java programs are supported?

    We are not supporting any programs with the alpha version of the code. This code is intended for your evaluation only. There is no support offered other than the alphaWorks discussion forum.

Linux JVM Installation Procedures

  1. Download the entire IBM Developer Kit in a single file named ibm-jdk-l116-linux-x86.tgz

  2. Place the downloaded file in a temporary directory, such as /tmp

  3. Make a root directory in which you want to place the IBM Developer Kit Example: You want to install the software in /usr/java116. Execute 'cd /usr' and 'mkdir java116'

  4. Enter the directory you have created and uncompress and expand the downloaded code using the tar command with the 'zxvf' options. Example: You are installing the code in /usr/java116 Execute 'cd /usr/java116' and 'tar zxvf /tmp/ibm-jdk-l116-linux-x86.tgz' (Note: this assumes you have placed the downloaded file in /tmp)

  5. Read the README file that has been unpacked in the root directory you created for the installation. The README will give further direction on adding your installed software to your PATH and running the tools provided in the IBM Developer Kit.
