Resolution:
This problem is related to GLOBAL NAMES.
The simplest way to disable global naming is to alter
the current session.
alter session set global_names=false;
The other solution is to add a global_name to the
gateway/hs:
HS_DB_NAME = <datasource>
HS_DB_DOMAIN = <DOMAIN>
But the HS_DB_NAME must not exceed 8 characters and
must not contain any extra characters. If this is not
possible, the globale naming can be disabled by setting
GLOBAL_NAMES = FALSE in the init.ora of the database
as well
