Sql-server – SQL Server Migration Assistant for Oracle

migrationoraclesql serversql-server-2005

I've recently installed SSMA and after connecting to both the Oracle instance (which holds the database to be converted) and the SQL Server I've mapped the necessary schemas from Oracle to MSSQL. The problem is that when I click on the report button for the assessment report there's an error popping up:

Assesment Error : Nothing to Process

The output window states:

Starting conversion… Analyzing metadata… Conversion finished with
0 errors, 0 warnings, and 0 informational messages. There is nothing
to process.

Does anyone who has experience with SSMA have any idea about this error? I can't figure out what I am doing wrong.

I would recommend you to use SQL Profiler (there should be such tools for Oracle too, we used Toad for Oracle) and see what queries SSMA executes to Oracle and MS SQL databases and what exceptions happen there ...

There are number of reasons why a tool can fail - in the past we used 3rd party migration tool that could fail if databases have different encodings (collations) especially when master SQL database was made CASE sensitive ... Though, I have no experience with SSMA, I would suggest that SQL profiling could give you a clue.
