Error value in ST02 - Extended memory (In Mem[KB])

[Former Member]

Hi,

I checked the transaction ST02 that the value of the Extended Memory - In Mem [KB] is wrong.

This value is not what is configured in the parameter (in / initial_size_MB), that is 8192 MB.

SAP Memory Curr.Use % CurUse[KB] MaxUse[KB] In Mem[KB] OnDisk[KB] HitRatio %

Roll area 12,98 42.558 43.624 163.840 164.000 99,02

Page area 41,41 352.763 747.456 400.000 451.968 94,00

Extended memory 2,25 6.041.600 6.733.824 268.435.456 0 0,00

Heap memory 0 0 0 0 0,00

Following result of command sappfpar:

Recently upgraded the kernel to patch (291). We have carried out the cleaning of Shared Memory.

What could be the wrong value?

Hi Bhuban,

Note 1532907 - ST02 displays incorrect values for nametab buffer sizes

We are in kernel patch last (Kernel Release 700 - patch 291)

Note 129813 - Windows: Problems due to address space fragmentation

SO is AIX (release 6.1)

Note 835474 - More than 32 GB extended memory

parameter ES/TABLE = SHM_SEGS

parameter em/initial_size_MB = 8192

parameter em/blocksize_KB = 4096

es/disclaim_threshold_MB = blank

es/blockdisclaimsize_KB = blank

Recently we have applied parameters of SAP EWC report, but the problem not was resolved.

What we can to do? Any ideas?
