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:
Go to http://sunsolve.sun.com.
Click “Patches and Updates”.
Click “Recommended Patch Clusters”.
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.
