Upgrade Script (catctl) Parameters

AutoUpgrade and Replay Upgrade use catctl parameters to perform upgrades.

Note:

Starting with Oracle Database 23ai, the catctl script is desupported. However, AutoUpgrade and Replay Upgrade integrate the options associated with catctl as part of their upgrade procedure. To use these options, refer to the Global or Local AutoUpgrade catctl_options parameters.
