Ok, now it seems to be almost sure, that our database developer can stay with us.
I'm glad for that, because now we don't loose the time where I have to become familiar with PL/SQL and our DB schemes and learn Oracle Database Administration.
Instead we can continue our product development with full throotle.
One regression though, I doubt that the new team member I tried to train before I got ill, won't come back to us in the foreseeable future because he has been pulled back into his previous project.
Today I have also finished an import script which transfers a huge requirements matrix from one of our customers into TaskZilla. Ran without errors and lightning fast, I didn't expect that. It took a week to write that script and I had to work around some errors in the source matrix but finally I was able to map all of our required fields. Yep.
