The undo update process stops if an individual operation within the undo fails. For example, if the current version of an object has a work area conflict, the process stops and the new version is not automatically used. Stopping the undo protects the work area data.
By default and for performance reasons, the undo_update command does not provide parallel version notification when it encounters parallel object versions. You can set parallel version notification by configuring the update_parallel_check user option to TRUE in your initialization file.
If you want to continue with the undo_update process, even though an individual failure has occurred, you can set update to continue. Set the reconf_stop_on_fail option to False.
The undo_update command supports these subcommands.
