Determining If Your Hosts Are Ready

Before you start the installer, review the issues that determine system readiness:

• Access Privileges

• System Requirements

• Memory, Disk Space, and Swap Space Requirements

• Patch Requirements

Access Privileges

To install Communications Suite software, you must be logged in as root, or become superuser.

System Requirements

Before you install, 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 the following:

• For Communications Suite product components, see theSun Java Communications Suite 5 Release Notes.

• For Java ES product components, see Platform Requirements and Issues in Sun Java Enterprise System 5 Release Notes for UNIX.

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

Memory, Disk Space, and Swap Space Requirements

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

• If the memory found on the host does not satisfy Communications Suite recommendations, the installer displays a warning. Installation can proceed, but you should upgrade memory later.

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

On Solaris 10, memory check is not performed if you are installing into a non-global zone.

Patch Requirements

During installation, the installer will discover any missing software patches. You cannot proceed with installation until these patches are installed.

To Install a Patch

the following example provides an example for installing a Solaris OS patch.

1. Go to the Sunsolve site: http://sunsolve.sun.com

   (Location for Linux patches: http://www.redhat.com)

2. Click Patches and Updates.

3. Enter the patch number in the PatchFinder text box, and click Find Patch.

4. Download the zip file for the patch.

5. Expand the zip file.

   For example: unzip 112785-44.zip

   A directory is created for the patch files.

6. Apply the patch.

   For example: patchadd 117885-44

   A directory is created for the patch files.

7. In the installer, click Check Again.

   All system requirements are rechecked. Additional material on patches can be found in the following release notes:

   • Communications Suite – Sun Java Communications Suite 5 Release Notes

   • Java ES – Sun Java Enterprise System 5 Release Notes for UNIX
