Performance of EHP4 Oil and Gas instance during interface loads

[Former Member]

I have EHP4 running usage type Oil and Gas running on unix 64 bit.

I have noticed the swap space usage increasing in the OS level.

How can I find which processes are consuming swap space and not releasing the swap space.

Where can I find out which user or which process is consuming swap space?

Thanks

Here is how to monitor memory usage within the SAP instance.

You can use transaction SM04 -> Goto -> Memory to see memory used per user. And you can use transaction SM50 -> double click on a running process to see the actual memory used by that process.

Besides that, you can use transaction ST02 to see the overall memory used (Extended and Heap memory are the most interesting):

SAP Memory      Curr.Use % CurUse[KB] MaxUse[KB]
                                                
Roll area            0.06        160     13,520 
Page area            0.02         56     61,272 
Extended memory     12.61    129,024    156,672 
Heap memory                        0          0

This can be difficult to determine from the OS level (depends on which flavor of Unix you are using). How much swap space are we talking about? 10 GB? 50 GB?
