Morning Gajendra, > I want to Install Oracle client for Toad connection which will be help > me to connect oracle 9i, 10g, and 11g which are exist on different host. > You are most likely best to install 11g client. The latest version is > 11.2.0.2 however, if you are running Windows 2000, the highest version > you can install is 11.1.0.6. Using 11g client in this way, you can connect from Toad to databases running versions as follows: 11.2.0.2 connects to 11.2, 11.1, 10.2.0.2 or higher and 9.2.0.4 or higher. Note, 10.1 is not a supported combination for this version of client. 11.1.0.6 connects to 11.2, 11.1, 10.2.0.2 or higher, 10.1 and 9.2.0.4 or higher. Now, it is possible that the client will still connect to other versions of Oracle databases, the above are the combinations that Oracle will support - given proper support contracts etc. For example, I have been able to get an 8.0.6 client talking to an Oracle 11.2.0.2 database. It works, until you try and select from a table which has a column in a data type that is new since 8.0.6 - timestamp for example. Then it fails miserably! -- Cheers, Norm. [TeamT]
