Hi all,
I've installed SAP ERP2005 and Solution Manager 4.0 on the same server with Windows 2003 Standard 32bit.
The RAM on this server is 3325MB.
How many paging file I must configure???
At the moment I configured the pagefile size as defined in the installation guide:
1 RAM + 8GB that is 12285MB.
Is it correct????
For both instance I set the PHYS_MEM parameter to 2328 (70% of the RAM)...is it correct??
P.S. How to calculate the [BE] parameters??
[BE] = maximum possible number of user calculated from the size of physical main memory
Thanks in advanced

We take the pagefile sizes as a good recommendation for systems in the lower RAM area (2 - 6 GB). For larger machines you will see less pagefile usage.
On a MSCS installation with 64 GB nodes we saw that we need 80 GB pagefile to allow the switching of the groups (R/3 and SQLServer).
And having enough room in the pagefile does not relief you from memory overcommit problems. It only lets your system keep alive.

will you use the ERP instance later for production or for tests?

I agree with Yaroslav,
you should NOT set those values:
em/initial_size_MB |---- [PM] |---- [PM] |Mbyte |
|--- em/max_size_MB |--- 20000 |--- 100000 |Mbyte |
| em/address_space_MB |----- 512 |----- 4096 |Mbyte |
|---- ztta/roll_first |------- 1 |------- 1 |Byte |
|--- ztta/roll_area |--- 2000000 |--- 3000000 |Byte |
| ztta/roll_extension | 2000000000 | 2000000000 |Byte |
| abap/heap_area_dia | 2000000000 | 2000000000 |Byte |
| abap/heap_area_nondia | 2000000000 | 0 |Byte |
| abap/heap_area_total | 2000000000 |[PM]*1048576 |Byte |
|- rdisp/ROLL_MAXFS | [BE] * 100 | [BE] * 100 |8KB Block |
|--- rdisp/ROLL_SHM | [BE] * 100 | [BE] * 100 |8KB Block |
|--- rdisp/PG_MAXFS |--- 32768 |--- 32768 |8KB Block |
|----- rdisp/PG_SHM |
so... that [BE] value is not to be used.
pagefile = 3325 * 2.5 = roughly 8GB
phys_memsize must be split in 2, so use 1328 for ERP2005 and 1000 for SolMan.
where have you heard about [BE]parameter?
