• How will you install optional software on a AIX machine?
• Firstly, what is optional software?
• Optional software are those which are not pre-installed when you install an AIX machine.
• Secondly, how will you identify the software product?
• The OS software could be identified with the following format as:-
www.kerneltraining.com/aix
• versionnumber.releasenumber.modificationlevel.fixlevel
• Version number- it may be 1 to 2 digits.• Release number- It may be 1 to 2 digits.• Modification level- It can be from 1 to 4 digits.• Fix level- It can be from 1 to 4 digits.• How to remember this? Vrmf• E.g.:- 05.02.0000.0000• Eg2:- 5.3.0083.2233• This is useful when we need to find the level of the
AIX OS using the #oslevel command

Now let us see some of the key words required to go further:-
1. Fileset- It is the smallest installable unit for the AIX OS, example of a completely installable unit is bos.net.uucp & example of a separately installable part of a product like bos.net.nfs.client
2. Packages- It is a group of separately installable filesets, which provides a set of related functions. Eg:- bos.net
3. Licensed Program Products (LPP) - They are a complete software product including all packages associated with that licensed program. Eg: - BOS

4. Bundles - They are a list of sofwares which contains filesets, packages, LPPs, which are used for a specified use. Bundles are the actual software.Example:- Server bundle, network bundle, graphics bundle
5. PTFs- It stands for Program Temporary Fix. It is a temporary solution to the problem. The problem is a result of a defect in a current unaltered release of the program. This problem is diagnosed by IBM.
6. APAR - It stands for Authorized Program Analysis Report. This is just a report of the problem caused due to the defect in a current unaltered release of the program. It is an emergency fix.

• Now let's see how the software hierarchy in AIX looks like:

Technology Levels and Service Packs• ML (Maintenance Level): It is no more called ML
but TL now (Technology level)
• Periodic patches and enhancements will be released by IBM for each and every fileset which is part of the OS or subsystem.
• Once higher version for all/most of the filesets in an OS level is released they are packaged into a single set called TL. (Eg: for os and TL level 5200-04 will be given an TL level set for 5200-05 after releasing all higher version filesets). A new AIX Technology Level is released roughly every six months or lesser than that.
• To see the TL level- #oslevel –r
www.kerneltraining.com/aix
• Service PacksAn AIX Service Pack (SP) is a bundle of PTFs released between Technology Levels. The PTFs/fixes address highly pervasive, critical, or security-related issues. To see the service pack level run
• #oslevel –s
• 6100-02-01-0847 (Means AIX 6.1 TL 02 Service pack 01)

• There are three installation modes in AIX
- Preview Mode
- Apply Mode (Save/replace)
- Commit Mode
