When you install the patch management tools, which is the smpatch command, several Solaris packages are added to your system, including some Java packages, that are required for the tools to run. In addition, several packages must be installed on your system before you can install the patch tools. These packages are as follows:
Solaris 2.6 release – Core cluster plus the SUNWmfrun, SUNWlibC, and SUNWxcu4 packages.
Solaris 7 and 8 releases – Core cluster plus the SUNWmfrun and SUNWlibC packages.
Solaris 9 release – Developer cluster (SUNWprog) is required if you are using the Solaris Management Console Patches Tool with PatchPro 2.1.
For information on verifying whether the required Solaris packages are installed on your system, see How to Verify Package Requirements for Signed Patch Tools (smpatch).
