Platform Requirements and Issues

Hardware Requirements by Operating System

The disk space and RAM required to install and use Java ES 5 can vary widely, depending on which components you install on a system. The following values are suggested minimums when installing all components on a single system. For more precise values, add together the values from the release notes for the components you are installing on a system.

Solaris Requirements and Issues

Recommended Solaris Update Levels

Although Java ES 5 is support on all versions of Solaris 9 and Solaris 10 on SPARC and x86 platforms, Sun recommends that you use the following updates:

• Solaris 9: Update 7 (9/04) or newer

• Solaris 10 SPARC: Update 1 (1/06) or newer

• Solaris 10 x86: Update 2 (6/06) or newer

Solaris Software Groups Supportd

Java ES runs on Solaris systems installed using the following Solaris software groups:

• SUNWCXall – Entire Solaris Software Group Plus OEM Support

• SUNWCall – Entire Solaris Software Group

• SUNWCprog – Developer Solaris Software Group

Minimized Installation on Solaris 10 (6331921)

Java ES can also run on a minimized Solaris 10 system installed using SUNWCreq (Core System Solaris Software Group) or SUNWCuser (End User Solaris Software Group), provided you are not installing Sun Cluster or Sun Cluster Geographic Edition.

To install Java ES 5 on Solaris 10 system that has SUNWCreq installed, add these packages:

If you will be using the graphical (GUI) installer, also add these packages:

Java ES has been tested with the two minimized Solaris 10 installations listed above. However, it is possible that using certain features of Java ES components may require additional packages.

Required Patch Clusters for Solaris

The Java ES installer checks your system for operating system patches required to run the components you are installing. To avoid failures of these checks during installation on Solaris, Sun offers patch clusters you can download and apply before running the installer. To acquire these patch clusters:

1. Go to http://sunsolve.sun.com.

2. Click “Patches and Updates”.

3. Click “Recommended Patch Clusters”.

4. Locate the patch cluster beginning with “Java ES Required OS” that applies to your OS version and download it.

Note that these patch clusters may contain Solaris kernel patches. Therefore, make sure you:

• Read the README for patch cluster carefully. Also, read the README for each patch in the cluster, especially the kernel patches.

• Install the patch cluster in single user mode, and perform a reconfigure reboot (boot -r) after installation. If some patches fail to install and report that a “reconfigure reboot is needed before invoking additional patch commands”, you need to install the cluster again after the reboot.

Also note that most of the OS patches required by Java ES are already included in recent Solaris updates. Therefore, if you are running a recent Solaris update, you can run the Java ES installer to discover the few patches you need to apply and download them instead of downloading the entire patch cluster.

Linux Requirements and Issues

root is not a valid user on Red Hat Linux 3 update 8 (AS and ES) for x86 (6460658)

When installing Java ES 5 on an x86 system running Red Hat Enterprise Linux 3 update 8, the "root" system user is not recognized.

Solution Before installing Java ES, first install the latest coreutils-4.5.3-28.4.i386.rpm and coreutils-4.5.3-28.4.x86_64.rpm from the Red Hat site.

HP-UX Requirements and Issues

Upgrades and patches required for HP-UX

Before installing, configuring, and running Java ES components on HP-UX, you must install certain software updates and patches. The updates are:

• Transport Optional Upgrade Release (TOUR) 3.1

• GOLDQPK11i(B.11.11.0509.429) Sept 2005 Quality Pack

  • GOLDAPPS11i(B.11.11.0509.429)

  • GOLDBASE11i(B.11.11.0509.429)

The patches are:

• PHSS_30966

• PHCO_29328

• PHKL_25842

• PHNE_29445

These updates and patches are available from the HP IT Resource center, http://itrc.hp.com.

Platform Virtualization Technologies Supported by Java ES 5

Platform virtualization is the ability to run multiple, unrelated guest operating systems in a contained environment on top of shared hardware. Due to the many benefits of platform virtualization, there are a spectrum of virtualization technologies and products available today.

Sun has tested and supports deployments of Java ES 5 on Solaris 10 environments virtualized using the Logical Domains (LDoms) software, which was introduced in Solaris 10 11/06.

LDoms runs on UltraSPARC T1-based and T2-based servers. For information about LDoms, it capabilities, and its requirements, see the Logical Domains documentation collection (http://docs.sun.com/coll/ldom1.0).

If you deploy Java ES components in a supported operating system within a virtualized environment other than LDoms and you encounter a problem, you may be asked to demonstrate the problem in a non-virtualized environment before Sun can respond with service.

As with deployments in non-virtualized environments, you should allocate recommended resources (processor, memory, storage, and so on) to each virtual machine so as to ensure sufficient levels of application performance. See the component documentation for recommended and supported system requirements.

Web Browsers Supported by Java ES 5

Web-based administrative interfaces provided by Java ES 5 components support at least the following web browsers:

• Firefox® 1.0.7 on Solaris 9 and 10, Windows 2000 and XP, Red Hat Linux 3 and 4, and Mac OS X

• Mozilla^TM 1.7.12 on Solaris 9 and 10, Windows 2000 and XP, Red Hat Linux 3 and 4, HP-UX, and Mac OS X

• Netscape^TMCommunicator 7.1 on Solaris 9 and 10, and HP-UX

• Netscape Communicator 8.0.4 on Windows 2000 and XP

• Microsoft Internet Explorer 6.0 SP1 on Windows 2000

• Microsoft Internet Explorer 6.0 SP2 on Windows XP

For information about the web browsers supported by the end user web interfaces provided by Java ES 5 components, refer to the release notes for the component that provides the interface. Release notes for Java ES 5 components are available at http://docs.sun.com/coll/1315.2. Also, see Component Release Notes.

Java Platform, Standard Edition (Java SE) Requirements

On Solaris and Linux, Java Enterprise System is certified with and includes Java SE 5.0 Update 9 (1.5.0_09). On HP-UX, Java Enterprise System is certified with and includes Java SE 5.0 Update 3 (1.5.0_03). Additionally, the following items are compatible with Java SE 1.4.2:

• Shared components

• End user client applications

• Public Java APIs

Specific components might support additional versions of Java SE or might have compatibility issues regarding certain versions of Java SE. For information, see the release notes for the component.
