I detected SAP note '1002839'.

I'm going to change the value of  'max_cells_one_index'.

To determine value of 'max_cells_one_index', I realize that I have to know hash table size and key figures.

Becasue notes mentions that 'max_cells_one_index' = hash table size * key figures.

However, I have no idea what hash table size means.

Can I find it in file 'TrexIndexServerAlert.trc'

Is there another way?
