Since a few versions, oracle driver for eZ always sends an "alter session" query when connecting. This to make sure that when numbers are gotten from db, the proper decimal separator is used.

BUT

With oracle drcp, any ALTER SESSION query is considered not reliable, and often refused by db with an error.

For supporting such case we should:

• allow ez NOT to send that query (via an ini setting of course, defaulting to "do the query")
• document the alternative: properly set NLS_LANG env. variable on the webserver(s) where eZ is running
