ORA_TZFILE

Specifies the location of time zone file.

Each file contains:

  • Valid time zone names

  • Offset from UTC

  • Abbreviation for standard time

  • Abbreviation for daylight savings time

In previous releases, the default value for ORA _TZFILE was

ORACLE_BASE\ORACLE_HOME\oracore\zoneinfo\timezlrg.dat

Starting with Oracle Database 11g Release 2 (11.2), the default value is

ORACLE_HOME\oracore\zoneinfo\timezlrg_11.dat

The timezone_version_number.dat data files contain most commonly used time zones and are smaller for better database performance. The new default, timezlrg_version_number.dat, includes time zones not defined in the smaller file.
