Adding an Unsigned Solaris Patch

You can use the patchadd command to add unsigned patches to servers or standalone systems. If you need to add a patch to a diskless client system, see Patching Diskless Client OS Services.

When you add a patch, the patchadd command calls the pkgadd command to install the patch packages from the patch directory to a local system's disk. More specifically, the patchadd command:

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

• Updates the patch package's pkginfo file with information about patches obsoleted by the patch being installed, other patches required by this patch, and patches incompatible with this patch

During patch installation, the patchadd command keeps a log of the patch installation in the /var/sadm/patch/patch-ID/log file for current Solaris versions.

The patchadd command will not install a patch under the following conditions:

• The package is not fully installed on the host.

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

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

• A patch with the same base code and a higher version number is already installed.

• The patch is incompatible with another, already installed patch. Each installed patch keeps this information in its pkginfo file.

• The patch being installed requires another patch that is not installed
