This section describes how to manage Oracle Solaris patches with the patch tools that are available.
The patch tools do the following:
Determine the Oracle Solaris version number of the managing host and the target host
Update the patch package's pkginfo file with this information:
Improvements have been made to the patchadd -M command. When you use this command to apply patches to your system, you are no longer required to specify patch IDs in numeric order. If you use the patchadd -M command without specifying a patch ID, all patches in the directory are installed on the system. For more information about these changes, see the patchadd(1M) man page.
The patchadd command cannot apply a patch or software update 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.
