Before you install Java ES, ensure that the hosts in your deployment meet the minimum hardware and operating system requirements. For the latest information on the supported platforms and software and hardware requirements, refer to “Hardware and Software Requirements” in the Sun Java Enterprise System 5 Release Notes for UNIX. If the operating system found on the host does not satisfy Java ES requirements, the installer cannot proceed. You must resolve this problem before installation.
As a convenience, recommended Java ES patch clusters are provided for the Solaris OS on the Sunsolve site: http://sunsolve.sun.com. A Java ES patch cluster contains all the Solaris patches required for the particular release of Java ES. These patch clusters might contain Solaris kernel patches, so be sure to read the patch cluster Readme file carefully, and especially any Readme files for kernel patches. A patch cluster must be installed in single-user mode, and the host must be rebooted after installation.
If you apply the patch cluster for your platform before running the Java ES installer, you can avoid delays when the installer performs the system check on your host and finds patches missing. However, if you are running a recent version of Solaris OS, you might prefer to run the Java ES installer first and only update those patches that the installer identifies as missing.
