Managing Solaris Patches

When you apply a patch, the patch tools call the pkgadd command to apply the patch packages from the patch directory to a local system's disk.

Do not run the pkgadd command directly to apply patches.

More specifically, the patch tools do the following:

• Determine the Solaris version number of the managing host and the target host

• Update the patch package's pkginfo file with this information:

  • Patches that have been obsoleted by the patch being applied

  • Other patches that are required by this patch

  • Patches that are incompatible with this patch

While you apply patches, the patchadd command logs information in the /var/sadm/patch/patch-id/log file.

The patchadd command cannot apply a patch under the following conditions:

• The package is not fully installed on the system.

• The patch package's architecture differs from the system's architecture.

• The patch package's version does not match the installed package's version.

• A patch with the same base code and a higher revision number has already been applied.

• A patch that obsoletes this patch has already been applied.

• The patch is incompatible with a patch that has already been applied to the system. Each patch that has been applied keeps this information in its pkginfo file.

• The patch being applied depends on another patch that has not yet been applied.
