Thanks Kiran
Before creating this discussion, I had run the queries mentioned in the SAP note to check how heap memory is being used. Of course that was the starting point any way.
Per SPID figures are available from the MDA table.
I also need to find fragmentation of heap pool and SPIDs that my be causing that.
Any way I have opened the case as well. So let us see this goes.
Thanks
