    Hello

    Buffer        HitRatio %    Alloc.  Export/import    98,96       100.000

    What matters is the Hit Ratio.

    A hit ratio of 99% is absolutely fine. There is no need to tune these parameters.

    Regards

      Hi Benjamin,

      Thanks for the Reply ..

      The Solution 2 of the Note 373986 states to maintain around 10% of the Free space, but we have more than 10% of the free space, So I think it is not applicable to us.

      Size          Allocated    KB   100.000
                     Available    KB 92.653                Used         KB 78.137                Free         KB 12.758 Directory entries Available          Available 20.000                Used                7.894
                     Free              

      12.106


      The Note 649613, is for lower releases and mine is SAPBASIS Release 7.01 and level is 06.

      Thanks and Regards
