With each new release of the Oracle Data Miner (ODMr) tool (part of SQL Developer) an upgrade of your ODMr Repository is needed. This is because of the numerous new features in the tool. This is particularly the case with ODMr (SQLDev) 4.2.
No most of the new features for ODMr 4.2 will not be visible until you are running a 12.2 Database. But a small number of new features are available if you are running an earlier version of the DB. Check out my blog post on some of these.
Before upgrading the ODMr repository, just like with any upgrade, make sure to do your backups. Although there is some coping of objects done during the repository upgrade (lot story but a few versions ago my ODMr repository and work got wiped during an upgrade), you should always export and save your workflows. You will need to do this using your current version of ODMr/SQL Dev before you start using ODMr 4.2.
When you have saved your workflows etc you can then start using ODMr/SQLDev 4.2.
The easiest way to do the ODMr 4.2 Repository upgrade is to let the tool do it for you. You can do this by trying to open one of your ODMr connections.
IMPORTANT: You will need to have the SYS password for the ODMr upgrade, so have your DBA do this step for you or have them on standby to enter the password for you.
NOTE: This upgrade is being done on a CDB/PDB 12.2 DB.
When prompted enter the SYS password.
When promoted click on the Start button.
The progress bar will let you know things are going.
When complete you will get the following.
It is always good to check the Log file/report. Especially if you encounter errors !
You can now start using all (well almost all) the new features of ODMr 4.2.
When the 12.2 Database is available you will get to see lots more features.
