Please find previous posts about the Data Migration Assistant for Unicode (DMU) here:

 

We included the DMU into our slide deck a while ago:

 

Upgrade, Migrate & Consolidate to Oracle Database 12c

 

DMU 2.1 is available (June 2, 2015)

Since Roy and I subscribed to the Hot Topics support email we'll find a very helpful note none of us was aware of almost every second day.

One of these recent finds is:

 

 

For those who have never heard of the DMU before you'll find a very brief overview about this tiny little - and very helpful - tool for database character set migrations not only to Unicode here: 

 

 

Why is this note so helpful?

 

Simply because it combines the most important topics about DMU in one note - from starting to issues. And this is really helpful when you plan to use the tool.

It is structured into:

 

  • A) Things to check before using the DMU
  • B) FAQ and common issues
  • C) Problems starting the DMU or during scan
  • D) Typical errors such as "invalid binary conversion" and others
  • E) Post conversion phase
  • F) Steps to do afterwards
  • plus some extras
