would be better to think of DLPAR as an operation to dynamically alter a virtual machine aka LPAR.
WPAR can be seen as the AIX implementation of the jail concept. Solaris has a similar construct known as containers. WPAR differentiate from others in that there are two types - system and application WPAR's.
An application WPAR isolates the application encapsulating the application in a protected environment that can be moved between AIX systems running at the same level.
A system WPAR appears as if it is a regular system. if you know where to look you can see the difference. System WPAR are also mobile capable.
Hope this helps.

seems to be WPAR is quite easy to set up..without additional licenses..
If I don't need Linux and all my legacy and new apps are happy in AIX 7.1 (the latest OS), I could save all troubles and use WPAR.
Can someone comment on this ??

I am trying to generate a report to track dlpar operation performed on a MS and was wondering if anyone has done this before.
I can get history from HMC using lssvcevents , but this does not give me details as to what quantity was added or removed .
Any thoughts ?
