Certain Solaris packages must be installed on your system before you install the Solaris patch management tools for signed patches.
For Solaris 2.6, Solaris 7, or Solaris 8 – Your system requires a minimal system configuration plus some additional packages. All the required packages are available from the End User cluster (SUNWCuser).
For Solaris 9 – You must have at least the Developer cluster (SUNWCprog) installed.
The following table shows the Solaris cluster and package requirements for running the Solaris patch management tools. Notice that when only a Solaris cluster is listed, the required packages are included in that cluster.
For information about verifying whether the required Solaris packages are installed on your system, see How to Verify Package Requirements for Patch Management Tools.
