SWAP coloumn is in RED In ST02

[Former Member]

Hi Techies,

the following are the current parameters set in the CRMEHP1 server. in the st02 swap coloum is in RED.

that is.,.. Table definition,Field definition,Short NTAB,Initial records,CUA, Screen, Generic Key,Single record,Export/import are in Red colour.

please help me.

Hello Pavan,

sappfpar determines the minimum and maximum (worst-case) swap space requirements of an R/3 application server. It also checks on shared memory requirements and that the em/initial_size_MB and abap/heap_area_total parameters are correctly set with the following procedure:

/usr/sap/<SYSTEMNAME>/SYS/exe/run/sappfpar check pf=/usr/sap/<SYSTMENAME>/SYS/profile/<Profile name>

At the end of the list, the program reports the minimum swap space, maximum heap space, and worst case swap space requirements:

Here is the link for it

Hi Pavan,

Can you give more information on which platform you are on?

If you are facing problems with swaps you can consider increasing buffer parameters and have a look at buffered objects in ST02.

You can tune these parameter and you should be fine then.

zcsa/table_buffer_area

zcsa/db_max_buftab

abap/buffersize

abap/pxa

rsdb/ntab/entrycount

rsdb/ntab/sntabsize

rsdb/ntab/entrycoun

Export/import buffer

rsdb/obj/buffersize

rsdb/obj/max_objects

rsdb/obj/large_object_size

Ashutosh

Hello Ashutosh,

Thanks for the reply. Presently im using Windows 2008 server Platform for CRMEHP1.

I will follow ur instructions and check. if there are any issues i will revert back to you'

Thanks &regards,

Pavan
