Dear All,

we are runing ECC5 on windows 2k3 enterprice Edition, we have 8GB physical Memory.

But in rz10 instance profile-->basic maintenance it shows ==> Initial / max. swap requirement = 3612 MB / 5520 MB

Please advice what to do

Hi,

in rz10 instance profile-->basic maintenance it shows ==> Initial / max. swap requirement = 3612 MB / 5520 MB

It shows the approximate total memory requirements of application server. It will consider the memory set and configured swap space/virtual space values.

Recommended Swap space size (Paging File Size--also known as virtual memory) based on OS version:

■ 32-bit: 1 GB plus 3 times RAM.

Maximum required is 10 GB.

■ 64-bit: At least 20 GB is recommended for standard installations

To check paging file size:

1. Right-click My Computer and choose Properties.

2. Choose Advanced u2192 Performance Options.

3. If required, in section Virtual Memory, choose Change.

PHYS_MEMSIZE = Available main memory for SAP instance to Run. You have to set it 70% of your total Installed Physical RAM size. 20% to 30% will be reserved for DB operations and 10% should be left for OS itself.

Please refer this useful SAP Note 88416 - Zero administration memory management as of 4.0A/ Windows to get more information on "How to set optimum value of PHYS_MEMSIZE parameter in different landscape scenarios".

i think it suppose to so 8192 MB?

that do you want to set to 8192 MB? Are you have DB on same server? Any other application like trex or content server?

8GB is low for production system (Of course anything can be).

for DB and OS you give all availabe ~ 0 GB ?
