Hi All,

We are having frequent issues where the memory is being consumed fully.

We have 16 gb of ram.

Why is that we are running out of memory even though we have enough RAM to accomodate oracle and SAP and linux OS requirements?

I wanted to know as what exactly the sappfpar reports? and PGA will be allocated on demand right?
