Determining Whether Your Hosts Are Ready

Before you start the installer, review the issues in this section.

System Requirements

Before you install Java ES, ensure that the hosts in your system 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 Microsoft Windows.

If the operating system found on the host does not satisfy Java ES recommendations, the installer cannot proceed. You must resolve this problem before installation.

Access Privileges

To install the Java ES software, you must be logged in as an administrator or as a user with administrator privileges. A privileged user is a part of local administration group. Users in nested groups are not considered privileged users. For example, a user from a group, which is a part of the administration group, is not considered a privileged user.

Memory and Disk Space Requirements

To run the Java ES installer, you need 500 Mbyte of disk space in the Windows system drive and 1.5 Gbyte in the destination drive.

The installer runs a check to determine whether your host has sufficient memory and disk space for the components you selected.

• If the memory found on the host does not satisfy the Java ES recommendations, the installer displays a warning but allows the installation to proceed.

• If the disk space found on the host is insufficient, the installer cannot proceed. You must resolve this problem before you resume the installation.

  You can solve this problem by mapping the %TEMP% to any other drive that contains required amount of free space.
