We are trying to get Discoverer 10G on Linux 64 bit set up with HS to be able to report on our Sql Server tables. I had to install 11G gateway and use the db4odbc program but the online gateway in the Discoverer ADmin is still greyed out. I can tnsping db4odbc and can do a sqlplus and connect to the sql server database just fine. I also did the entry into the eul_gateway table. And still no luck. Has anyone got this working on 64 bit linux? I have a tar open with Oracle Support and they are telling me to use the 32 bit HS which on my Linux box I get errors when I do the same sqlplus command. Which previously they told me I had to use the 11G gateway to get this to work. Thanks K
