Thanks Gail.

INS1 is taking only 3 GB out of 8 GB max memroy and INS2 is taking only 1 GB out of 4 GB max memory

So total 4 GB is used for both the instances out of 16 GB. So where is the rest of memory 12GB going?

One thing I'm not able to understand is where the memory is going and how to find where the memory is going?

What should be the Ideal or acceptable value for AvailableMbytes?

Can you please shed some light on this?

Thanks in advance.
