Application considerations

You should be aware of several things concerning the applications associated with an LPAR.

Generally, an application is not aware that it is running in an LPAR. There are some slight differences that you are aware of, but these are masked from the application. Apart from these considerations, AIX® runs inside a partition the same way it runs on a standalone server. No differences are observed either from the application or your point of view. The LPAR is transparent to AIX applications and most AIX performance tools. Third party applications only need to be certified for a level of AIX.
