Hello All,
I have doubts regarding the values of nametab buffers:
Nametab (NTAB)
Table definition
Field definition (rsdb/ntab/ftabsize)
Short NTAB (rsdb/ntab/sntabsize)
Initial records (rsdb/ntab/irbdsize)
I have set
Field definition (rsdb/ntab/ftabsize)
Short NTAB (rsdb/ntab/sntabsize)
Initial records (rsdb/ntab/irbdsize) independently in RZ10. But that value is not displayed in ST02.
So my question how the values of these buffers calculated for ST02?
I can see another parameter - rsdb/ntab/entrycount.
It is max. number of table def. buffered.
What is relation between this and the values of the above 3 parmeters in KB?
Furthermore, there is no separate parameter for Table definition.
How is its size in KB calculated?
You can get all the description and documentation in RZ11, basically they all have basic default values set as standard by SAP, beside that you can adjust them on demand to fit the requirements of your own system... like excesive swapping.

That the parameter for the Table definition buffer

Hello,
I see that the buffer parameters are governed by 2 things
Number of Entries and User Data in KB
Lets take the example of Initial record(IRBD)
Number of Entries - rsdb/ntab/entrycount / 4
User Data[in Kilobytes] - rsdb/ntab/irbdsize
So, if I keep rsdb/ntab/entrycount = 20000 (thereby no. of entries = 5000)
and rsdb/ntab/irbdsize = 100 (thereby user data = 100Kb)
Then it would be able to accommodate very few entries, because the size is too small.
Thus the no. of entries parameter is useless in this case.
So could you clarify, whats the use of governing a buffer with 2 different parameters?
