Inconsistent memory size on solaris with SAP

[Former Member]

Hi all,

We have a strange issue in our SAP (ECC6) on solaris 10. We have set 3GB of extended memory in profile parameter, but the prstat -a command in OS returns almost 13GB for SIDadm user, (ORAadm usage seems normal, around4 GB).

Any idea how can I figure out which SAP processes use the other 10 GB...Your feedback much appreciated.

Thanks.

- Check ST02

- how big are you buffers (abap/buffersize etc.)?

- how big is ztta/heap_area_total?

Hi Markus,

The extended memory is ST02 is 3 GB - the used memory has not reached this max value.

abap/buffersize is 300.000 KB (default since installation)

abap/heap_area_total is 2 GB

Thanks

Please execute as <sid>adm

sappfpar check pf=<full-path-to-instance-profile>

and post the output.

Hi in st02 --> detail analysis menu --> storage check Virtual memory allocated

P.S. are you think prstat are good way to check it? How much memory are free in total on your box?

Try to check in st06n or directly vmstat 5 --> free

Hi my friend

Please check parameter em/initial_size_MB for ABAP instance, which determines how many extended memory is allocated. And also dispatcher/server nodes memory setting per note 723909 if this is a dual stack system.

Thanks Fan Yu,

The parameter em/initial_size_MB is exactly 3 GB as per shown in RZ10 memory management screen, and our system is definitely ABAP stack only, I installed it by myself...Any other suspect?
