Jayakumar,
AIX is trying to get the most out of your memory, it is using the available memory as file cache. This to prevent reading from the 'slow' disks and thereby speeding up the system. When there is no paging then there is no reason to worry. If you want (and really, really want) to influence this behavior you can fiddle with the famous minperm/maxperm parameters..
If you look in this forum for the string "aix memory breakdown" you might find more info about this subject, "pagink" included a link that might give you a more in depth answer.
