A usefull command to update software on your AIX server is install_all_updates. It is similar to running smitty update_all, but it works from the command line. The only thing you need to provide is the directory name, for example:
# install_all_updates -d .
This installs all the software updates from the current directory. Of course, you will have to make sure the current directory contains any software. Don't worry about generating a Table Of Contents (.toc) file in this directory, because install_all_updates generates one for you.
By default, install_all_updates will apply the filesets. Use -c to commit any software. Also, by default, it will expand any file systems; use -x to prevent this behavior). It will install any requisites by default (use -n to prevent). You can use -p to run a preview, and you can use -s to skip the recommended maintenance or technology level verification at the end of the install_all_updates output. You may have to use the -Y option to agree to all licence agreements.
To install all available updates from the cdrom, and agree to all license agreements, and skip the recommended maintenance or technology level verification, run:
# install_all_updates -d /cdrom -Y -s
