    Hi Lisa,

    SWAPs themselves are not an indicator of a performance issue.It's unlikely you can avoid them from happening in production systems. What matters is a quality of buffer tuning and a number of swaps hapenning every day. Let's say you are getting more then 10000 swaps each day for the program buffer. Then you'd need to pay attenation to this buffer and try to find out a way to reduce swaps.

    Here is the link to SAP help:

    Hi Mike,

    Thanks for your answer. If i increase extended memory then my problem can resolve.Currently memory is very less.

    If i increase extended memory (physical memory)then what are the SAP parameters i need to change? like instance profile to replicate to SAP.

    Please suggest'.
