swaps-st02 are in red colour

[Former Member]

R/s All,

In my Production Server (ECC6DB2 v.9.1Win2k3x64 with 40 GB of physical memory) when i perform st02 the field definition,initial records,program,CUA,generic key,export/import,buffer shows value RED under the swap category. Current memory parameters values are as follows. Kindly help us to reslove the problme.

ztta/roll_area - 6500000

ztta/roll_first - 1

ztta/short_area- 4000000

rdisp/ROLL_SHM- 32768

rdisp/PG_SHM - 49152

rdisp/PG_LOCAL - 150

em/initial_size_MB- 16285

em/blocksize_KB- 4096

em/address_space_MB- 4096

ztta/roll_extension - 2000000000

abap/heap_area_dia- 2000000000

abap/heap_area_nondia- 0

abap/heap_area_total- 12881756160

abap/heaplimit - 40000000

regards,

Consider hit ratio. it is an important factor.

when you restart the instance, the st02 buffer errors will be gone.

A red field in ST02 is NOT necessarily a problem. If you have performance problems and you can link them to buffer issues THEN it is a problem.

The only productive systems i have seen so far with no red buffers at all were either not having much activity or the setup was wasting hundreds mb of memory. I recommend to consider the hit ratio as well. If for example your program buffer is above 99%, there is no need to further increase it.
