This is a screen shot of the DBUA Upgrade Options screen.
At the top of the screen is the following text:
Upgrade process may invalidate objects in the database. Oracle recommends recompiling of invalid objects as a part of upgrade. Based on the number of CPUs Oracle has set the following default degree of parallelism. Parallel recompilation reduces the recompilation time.
You can then select Recompile invalid objects at the end of upgrade, choose the Degree of Parallelism, and select the option to Backup database before you start the upgrade and specify the directory location for the backup files.
This text and options are discussed in the following step.
At the bottom of the screen are Cancel, Help, Back, and Next buttons.
