I am trying to figure out how to install Sun Patches. I have a list of recommended patches that need to be applied to my 3500 server. Can anyone provide a step by step "How To Install Patches" guide.
Sorry, but how do you retrieve the instructions for "Insatlling Patches" from the downloaded tar files. I am very new to this. Thanks for responding
If you are talking about the recomended patch cluster that you download from Sun (or get off the SunSolve CD).
Solaris 7 & 8 patches are zipped, so download the file and run
# unzip 7_recommended.zip
other versions are compressed tar files, once you have downloaded the file run
# uncompress 2_6_recommended.tar.Z
# tar -xvf 2_6_recommended.tar
Then move into the patch directory
# cd 2_6_recommended (or whatever version you are using)
# ./install_cluster (ideally the machine should be in single user mode before you actually install, if this is not possible do it at a quiet time)
Follow the on screen prompts and reboot afterwards.
If you are not installing a patch cluster, download the individual files and continue as above for each one.
You may find that one patch requires another to be loaded first, if this happens carry on with the others and go back to the failed ones at the end.
Before you install any patch , it would be good to know what you have already installed on your system.
To find which pathes have already been applied do :
showrev -p
Then download the needed patches
unzip or untar them in any temporary directory
(could be /var/spool/patch) and do what we have to do for every patch, go thru the README to see the prerequisites, disk space requirements , etc anf follow the instructions on the screen when you run install_patch or install_cluster.
It is very straighforward and easy. And nowwadays, it rarely bombs.
Dont worry, in case of problems after applying the patch, you can always do a backout unless you specified no backup during the install of the patch.
