Related Error Messages:

Cause: An attempt was made to use a date expression whose format does not fully (i.e. day, month, and year (including century)) specify a date as a partition bound for a DATE column. The format may have been specified explicitly (using TO_DATE() function) or implicitly (NLS_DATE_FORMAT).

Action: Ensure that date format used in a partition bound for a DATE column supports complete specification of a date (i.e. day, month, and year (including century)). If NLS_DATE_FORMAT does not support complete (i.e. including the century) specification of the year, use TO_DATE() (e.g. TO_DATE('01-01-1999', 'MM-DD-YYYY') to fully express the desired date.

ORA-21526: initialization failed

Cause: The initialization sequence failed. This can happen, for example, if an environment variable such as NLS_DATE_FORMAT is set to an invalid value.

Action: Check that all NLS environment variables are well-formed.
