Checking Patch LevelsBefore installing OE patches, you should

know about patches that have been previously installed on a system“# showrev -p”“# patchadd -p”

Historical information about all patches that are currently installed on a system and that can be uninstalled is stored in the “/var/sadm/patch” directory

Preparing patches for installationDownload the patches to the local system

and place it in “/var/tmp” directory (open to all directory)

Solaris 7,8,9 OE patches are in .zip format, unzip to unpack the patch files“# /usr/bin/unzip 105050-01.zip”

Earlier versions user compressed tar file in a “tar.z” format, for uncompressing “zcat” command is used

Installing a PatchWhen a patch is installed “patchadd”

command calls the “pkgadd” command to install the patch packages“# cd /var/tmp”“# patchadd 105050-01”“# patchadd -d 105050-01” - will not save

copies of file being updated or replace

Removing a PatchWhen removing a patch, the “patchrm”

command restores all files that were modified or replaced by that patch, unless:The patch is required by another patchThe patch has been obsoleted by a later patchThe patch was installed with the “patchadd -d”

option

unzipped or uncompressed and extractedDecide on which method to use to install

the cluster - the recommended default save option or the “-nosave” option
