ST22 Short Dump STORAGE_PARAMETERS_WRONG_SET

[Former Member]

Hi

We have a NW04 BW 350 system running on Windows 2003 32 Bit/MS SQL 2000 32 Bit.

When I go into RSA --> Monitoring --> PSA it says 'constructing administrators workbench' then fails with the short dump:

<b>STORAGE_PARAMETERS_WRONG_SET</b>

The shortdump reccommends increasing parameters abap/heap_area_dia and

abap/heap_area_nondia, I would have thought you would want to avoid using HEAP memory as this locks the memory into a single work process ?

Looking at the memory consumption in the shortdump :

<b>Memory usage.............

Roll..................... 1709536

EM....................... 108964960

Heap..................... 406948064

Page..................... 57344

MM Used.................. 495709152

MM Free.................. 17059832

SAP Release.............. "640"</b>

EM has only been used for about 100 MB, then it go's to HEAP memory.

Looking at ST02 the system has 4GB EM and only 1.7GB used at 42%, so why would the process only use 100 MB of EM?

ztta/roll_extension is set to default 2GB so it appears EM memory should be utilised more by the work process before going to HEAP memory.

What parameters affect the usage of EM before entering HEAP usage?

Thanks for any advice.

I have just found parameter :

em/address_space_MB

this is set to 250 MB, it looks like a parameter which is valid for Windows SAP systems, and sets the address space that is reserved for the user context, this has to be contiguoius space.

Is this why EM memory is exhausted for the Dialog process when EM use reaches above 250 MB? would it be advisable to increase this parameter ?

Hi ,

Can you provide the details like current patch levels etc.

is this problem frequent or occasional?

Hello,

Kindly go through this link to understand how SAP memory utilization happens

http://help.sap.com/saphelp_nw70/helpdata/en/02/96253c538111d1891b0000e8322f96/frameset.htm

I hope this will resolve your query about how SAP memory gets used.

Thanks & Regards

The help does not explain why so little EM memory is being used when available before going to Heap in a dialog session?
