HI,
Your hitratios look good with exception of InitialRecords which is only 82%.
As mentioned by the other bloggers here check your history part of ST02 this will indicate if it is of any concerts. For which you can open by starting the RSTUNE56 report or transaction ST02 and selecting History (Shift+F6)
For initial records perhaps increase the following two parameters.
rsdb/ntab/irbdsize
rsdb/ntab/entrycount
Also check your export/import buffers.
649613 - Export/import buffer SWAPS
As per the aforementioned note:
Monitor the buffer with transaction ST02 and, if necessary, increase the profile parameters.
The following profile parameters are relevant to the export/import buffer:
rsdb/obj/buffersize
rsdb/obj/max_objects
If, in transaction ST02, "free directory" for the export/import buffer is very small or 0, rsdb/obj/max_objects must be increased. If "free space" displays very small values, the parameter rsdb/obj/buffersize is set too small and must be increased
Kind Regards,
Johan
