Question by saminoahgabriel: Is it possible to install oracle 10g on server and 11g on client and vice-versa?
Is it possible to install oracle 10g on my server computer and oracle 11g on my client computer and vice-versa?
In order to get the best compatibility, you should install the version of Oracle client to match the version of the database on the server.
Note that you can have multiple instances of Oracle installed, so the 10g client and the 11g client can reside on the same server.
