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
