IBM was asked to evaluate the performance of our iSeries.  Particularly the
nightly batch processing.  To summarize, their recommendations pretty much
all pointed us to switching from DDS to SQL.

Frankly, I find this amazing. What examples did they give of where SQL would provide a performance benefit ?

Are we talking about using EVI's and/or other enhancements unavailable except via SQL or is this a blanket statement.

I have so far failed to understand what "converting to SQL" actually entails. Does it include recreating all your existing files to reference SQL instead of DDS ? Wouldn't this be a hugely unproductive exercise if performed just for the sake of it ?

I can see where some specific implementations or changes to the database might provide benefit but to change everything smacks of religion not technology.

Any examples or light you can shed on IBM's statements would be most appreciated.

Evan Harris.
