How the Installer Checks for System Readiness

After the components you have selected are found to be acceptable for installation and you have indicated their target installation directories, the Java ES installer performs a system check to determine if your host meets the requirements for the components you selected.

The installer checks for disk space, memory, swap space, operating system, patches and operating system resources based on the selected components and the installation directories provided. The following messages inform you about the state of your host:

• System is ready for installation. When this message is displayed, the installer can proceed.

• System is ready for installation, however, a resource, such as memory, is not at the recommended level. When this message is displayed, the installer can proceed but you should consider providing additional resources.

• System does not meet the minimum system requirements. When this message is displayed, in most cases the installer cannot proceed. A typical situation is when patches are missing. You must install most missing patches before proceeding with installation. In some situations, you are allowed to proceed without installing a missing patch. In this case, if you choose to proceed, you are warned that installation might fail or software might malfunction. To continue with installation, you must confirm that you want to proceed without installing the missing patches. For more information on patches, refer to Patch Requirements or To Install a Patch.
