ORA-1804 indicates that there is a problem with the timezone information that the database keeps. There can be many symptoms that are associated with this.
For example a very simple way of getting this error when there are problems with the timezone information is by attempting to set the session timezone (or the database timezone) to a named timezone:
would give "no rows".
Note if above select from v$timezone_names gives rows then your CURRENT RDBMS DST version is most likley simply to old and missing SOME timezones, in that case see <NOTE:412160.1> - Updated DST transitions and new Time Zones in Oracle Time Zone File patches / I) What timezones are known / I'm missing timezones in the Oracle Database?
The exact number of timezones in this view depends on the version of the database you are using, but there should be a minimum of 616 rows in this view.
