dotConnect for Oracle connection issue Windows Vista 64 bit

Post by basem » Tue 27 Jul 2010 05:11

I have the following error when trying to Oracle ....

ORA-12154: TNS:could not resolve the connect identifier specified

I'm using the following ...
- Visual Studio 2008 in Windows Vista SP2 64-bit OS
- Oracle Database 10g Express Edition Product Version (There is only one ORACLE Home installed on the machine).
- Devart.Data.Oracle.dll version
- Devart.Data.Linq.dll version

The error pops up when trying to connect to the database from the "Connection properties" dialog box of the "Database Explorer - Entity Devloper" within VStudio.

I'm using the following tnsnames.ora file ...

XE =
(ADDRESS = (PROTOCOL = TCP)(HOST = Bassem-PC)(PORT = 1521))

Could you please specify the connection properties you are setting in the dialog? Also, are you able to connect to the server using some standard tool like SQL Plus (with the same connection properties)?
