Performance Issue

Dears,

We are facing Performace issue in our system.

Dialog responce time is near to 1600 ms.

I checked the system and find that our Program,Screen and Export/Import buffer are getting full again and agin.

I also checked that heap memory is also being utilized that I think should not be utilized in normal case.

Now I am planning to increase buffer space but my question is do we have space on OS level also to increase it.

In ST06

Memory

Physical mem avail Kb 163445720 Physical mem free Kb 91127904

Pool

Configured swap Kb 167755776 Maximum swap-space Kb 331217880

Free in swap-space Kb 250708744 Actual swap-space Kb 331201496

Some times I have also found error in CCMS that no physical memory is available.

As I understands this Physical Memory is RAM of system and Swap space is Paging memory .

And buffers will take space from this physical + Swap Space.

Please suggest.

Regards,

Shivam Mittal

    :-o

    You surley have enough unused memory to increase any buffer you like !

    May be you should give us some data of what is configured yet.

    From Oracle:

    db_cache_size

    shared_pool_size

    pga_aggregate_target

    from SAP

    *wp_no_???

    abap/buffer_size

    em/inittial_size_MB

    If Windows PHYSICAL_MEMSIZE

    For starters: With 90G not beinig used, I'll start giving 20G to db_cache_size

    set / upgrade abap/buffersize to 1,5GB and may be use some more Workprocesses.

    Hi Shivam,

    Performance is quite big and you need to always add the info. like your OS/DB, Well you can see below SAPnote as per your OS/DB. Also its not easy to get the solution for performance as all the implementation on SAP worldwide are different and highly customized.

    AIX (UNIX flavour)

    Note 1121904 - SAP on AIX: Recommendations for paging space

    Windows you can go for Zero Administration

    Note 88416-Zero administration memory management as of 4.0A/ Windows

    Hope it will help you to find out the solution
