Help needed on abap heap area parameters

Hi Gurus ,

I need your help in regards with abap heap area parameters , we are facing a lot of system no roll memory issues on one of our instance.

As for my understanding :

1)abap/heap_area_dialog : heap memory limit for dialog process.

2).abap/heap_area_nondialog: heap memory limit for non-dialog process.

3).abap/heap_area_total : what this implies ?

In my production instance the parameters are as follows :

Actuals

abap/heap_area_dialog -


2GB (Recommended : 2GB for an application server with max 50 users )

abap/heap_area_nondialog:-- 2GB (Recommended : 2GB or an application server with max 50 users )

abap/heap_area_total --- 1GB (Recommended and default value: 2GB)

My doubt is "abap/heap_area_total of 1GB " might creating problems .

What is the recommended value for abap/heap_area_total on Solaris 10 ?

your valuable inputs required :!

    Hi,

    You can check details about the different parameters from RZ11 parameter. As such there is no standard values for these parameters. This needs continuous improvement. You can increase the value of these parameters then over a period of time, monitor the system if you see there is chance of further improvement then you have to change the parameter again.

    Thanks

    Sunny
