If you download this text file to your AIX system you can then use the compare_report command to see which fixes you need and how the level of your system compares to that of the patch-set. e.g.
# compare_report -s -r ./6100-08-00-1241.compare -h -v
This example will generate a list of the patch-sets that are of a higher or lower level than those in the fix-pack. For more details see the compare_report man page.
Once you have downloaded your patch-sets to your system you can either install them from smit or by using my preferred method:
Change to the directory where you dowloaded the patches and run:
# inutoc .
# install_all_updates -Yd .
install_all_updates: Initializing system parameters.
install_all_updates: Log file is /var/adm/ras/install_all_updates.log
install_all_updates: Checking for updated install utilities on media.
install_all_updates: Result = SUCCESS
(Where -Y accepts all licence agreements and -d identifies the directory where the patches are stored)
The installation command produces a handy report in"/var/adm/ras/install_all_updates.log" that can be used to analyse the results of the pactch operation.
