Can SQL express be accessed by Oracle Transparent Gateway ?

Able to access SQL express remotely using SQL mgt Studio after certain configuration.

But notice that I must use IP address/SQLEXPRESS for server name in order for connection to work. What is this "/SQLEXPRESS" ? Is it a standard surfix for SQL Express ?

I have installed the Oracle Transparent Gateway on the machine with SQL Express and setup the tnsname for SQL Express. For the tnsname, have used IP address/SQLEXPRESS as the host name but it gave this error :

ORA-28545: NCRO Failed to make RSLV connection

Tried with just the IP address and it gives the same error.

Any idea ? ? Help !

Hi,

What is this "/SQLEXPRESS"

That si the instance name, as you can deploy several instances (liek in Oracle on one machine, with the difference that one instance can have more than one database :-) ), the instances are bound to a port, if it is not the default port (1433), you have to specify it, either within the connectionstring are in your Gui.

HTH, Jens Suessmeyer.

|||I check the SQL Server configuration manager and it shows that the instance name is MSSQL.1. So which one is the instance name ?
