I'm pleased to announce the first release of ZcxOracleDA - a Zope
database adaptor for Oracle using the cx_Oracle library.

This is an initial development release and should be used with caution!

Z cxOracle DA

  This is a Zope Database Adaptor for cx_Oracle. It's currently only
  been tested with Zope 2.7 and above with cx_Oracle 4.3.1 and above.


    You must install cx_Oracle before attempting to use this DA.

    You can find cx_Oracle at::


    Then extract this product into your Zope instances Products

  Connection Strings

    The connection string is passed directly to cx_Oracle.connect(). 

    The string is usually of the form username/password at TNS

  Known Issues

    cx_Oracle returns date types as python datetime.datetime types. The
    DA will check the queries description to see if any of the rows 
    being returned are of that type and if they are will convert them
    on the fly to Zopes DateTime type. Unfortunately this currently
    means the DA iterates through all the rows returned and modifies
    the return values which is far from optimal.

    Also the DA currently doesn't handle returned datetime timezones
    well. It currently converts all datetimes to UTC regardless of the
    timezone Oracle is using. Ideally the DA would query the current 
    Oracle DBTIMEZONE and use that instead. If you want to change the
    timezone used for datetime conversion then edit db.py and modify
