Introduction

I won’t go into detailed explanation of what a patch is, but you should know that by applying patches (fixes), you can eliminate bugs and security vulnerabilities.

Detecting Patches 

  showrev -p
  
  Patch: 106793-01 Obsoletes:  Requires:  Incompatibles: Packages: SUNWhea . . .
  
  patchadd -p
  
  Patch: 106793-01 Obsoletes: Requires: Incompatibles: Packages: SUNWhea 
. . .

These versions should be identical. If they’re not, it means a patch has been applied.

You can also see the different system patches here:

  ls /var/sadm/patch
  
  107558-05  107594-04  107630-01  107663-01  107683-01 107696-01
107817-01  107582-01  107612-06  107640-03

Retrieving Patches

For France, here is the address for Solaris patches: http://sunsolve.sun.fr

Then, on Sun’s FTP site, get the latest version:

  cd /var/tmp
  
  ftp sunsolve.sun.com

ftp> mget 112605*
mget 112605-01.zip? y

Decompress the patch:

  /usr/bin/unzip 105050-01.zip

Implementing Patches

Here are the existing commands:

  • patchadd - Install a patch
  • patchrm - Remove a patch
  • smpatch - utility to download and install a patch

patchadd

Let’s install the patch:

  cd /var/tmp
  
  patchadd 105050-01
Checking installed patches...
Verifying sufficient filesystem capacity (dry run method)
Installing patch packages...
Patch number 105050-01 has been successfully installed.
See /var/sadm/patch/105050-01/log for details.
Patch packages installed:
  SUNWhea

pathrm

To remove a patch:

  patchrm 105050-01
  
  Checking installed packages and patches...
Backing out patch 105050-01...

Don’t forget to restart the machine after applying a patch.
