EBS database upgrade 10gR2

After installing the EBS 11.5.10 multinode, I asked myself what could be next....I decided to upgrade the database (9.2.0.6) to 10gr2 (10.2.0.2.0)
It took me a few days of hard work, but finally the upgrade has finished and I am now performing the last steps to complete the upgrade and if the EBS is still working.

I used Metalink note 362203.1 to upgrade and choose to manually upgrade the database instead of using the database upgrade assistent (DBUA).
More to come...
