May sound like a silly question, but does Oracle implicitly execute ALTER SESSION statements for any connection into the database? My suspicion is it must do, to ensure local variables like time zones and languages are set correctly. We are currently going through our SQL and picking out candidates for tuning, we constantly come across this statement from almost every single application, whether home-grown or off the shelf, be it VB, ProC , C++, etc.

ALTER SESSION SET NLS_LANGUAGE= :1 NLS_TERRITORY= :2 NLS_CURRENCY= :3 NLS_ISO_CURRENCY= :2 NLS_NUMERIC_CHARACTERS= :4 NLS_CALENDAR= :5

NLS_DATE_FORMAT= :6 NLS_DATE_LANGUAGE= :1  NLS_SORT= :7 TIME_ZONE= :8
NLS_DUAL_CURRENCY = :3 NLS_TIME_FORMAT = :9 NLS_TIMESTAMP_FORMAT = :10
NLS_TIME_TZ_FORMAT = :11 NLS_TIMESTAMP_TZ_FORMAT = :12
