Hello

I tried creating the 100G configuration of dell DVD store.
The data files used around 68G of space. I created DB out of the data files which took around 48G.

While running the mono driver in mysqlds2/, I saw follwing error
===============================================================
pct_newcustomers= 20 n_searches= 3 search_batch_size= 5 n_line_items= 5 virt_dir= ds2 page_type= php target_hostname=

Thread 0: MySql Error 0 in Purchase: Invalid attempt to access a field before calling Read()

===============================================================

What can be the real cause of this ?

Any help would be appreciated.

Hi Sandeep-

I'm impressed that you got the mono driver as well as the MySQL DS2 kit working as much as you have - we haven't updated either in 5 years.

Before you get too deep into debugging the driver program can you access the database through the php interface with a browser? I would check that you can run all 5 functions manually before trying to drive it with ds2mysqldriver. Then, if you still get errors you might want to test the driver program on Windows first, to eliminate mono as a cause of the problem. If all that fails you may need to update the stack components. Five years is a long time!
