I need to have Oracle v11.2.0.3.0 installed in order to install MSS 11.3. How can I tell what version I currently have installed?

 

 

One way of determining the version of Oracle installed is to open the SQL Plus window. The version is displayed at the top of the window. There is no need launch SQL Plus to see the version.

 

 

Go to:

Start > Programs > Oracle > Application Development > SQL Plus
