How to check process and memory status in AIX

During monitoring we check the processes in SAP SM50 but if the SAP system is running for a long time, ST06 may show the RAM is reducing even though the system load is less. This results in less availability of RAM for other processes.

We need to trace the process that is consuming considerable amount of RAM. In AIX us the following command :
ps aux more
General view can be optained by command :
topas
Vitual memory state can be known by :
vmstat 01
