Re: What does SQLDeveloper change?

system.data.oracleclient is Microsoft's .net provider for Oracle. It's complaining that it can't find appropriate Oracle Client libraries. If you are setting ORACLE_HOME or similar that might cause that error. I know next to nothing about SSMA, but there is an Oracle supplied .net set of libraries that support Oracle much, much better than the MS ones did.
