Question

I\'m trying to learn and figure out if it is possible to deploy an MVC, EF, ODAC 11.2.0.3 app to a server that has a previous version of ODP.NET installed. Rather than updat

Answer 1

It seems from your question that you need to deploy an update to your application and the new version of ODP.net using only xcopy deployment permission.

Since your application is being changed, then you shouldn't need the assembly binding changes or DbProviderFactories. Just update the csproj of the class library with your edmx etc to have a reference to the new ODP.net version, eg

If you get an issue with your tnsnames.ora, then you would have to do one of the following: a) Add a system environment variable TNS_ADMIN to point to the directory of the tnsnames.ora, or b) Change the connection string to something based on:

Data Source=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=MyHost)(PORT=MyPort)))(CONNECT_DATA=(SERVER=DEDICATED)(SERVICE_NAME=MyOracleSID)));User Id=myUsername;Password=myPassword;

c) See if you can put a copy of the tnsnames.ora somewhere else.
