Update of version 11.2.4 HF.2.build.777 fails with “U00000002 EXISTS” error
Issue/Introduction:
Error Message :
U00000002 EXISTS
When upgrading the Automation Engine to version 11.2.4+hf.2.build.777, the DB Load utility will fail with the error message when attempting to load the Initialdata (UC_UPD.TXT).
This is only affects AE version using the Inital Data version 11.2.4+hf.2.build.777.
In case the very same error message shows up, but Initial Data is not on version “11.2.4+hf.2.build.777”, the resolution in this article will not be effective.Due to a bug in the Initial Data version mentioned above, the object name and object number of an Initial Data object was mixed up.
This has no impact to the system at all! Everything is working as expected.
However the next update of the Automation Engine will fail. That means, once this version is installed, an update to a newer version will not work.
During the upgrade of the AE database, the load of the Initialdata “UC_UPD.TXT”, the DB Load will fail with the error:
U00000002 EXISTS
This is what the DB Load log looks like:

This error doesn’t necessary mean, that it is exactly this issue. Only a database trace level 4 of the DB Load process shows the affected object and will look like:

Resolution:
The issue can be resolved right away, even no update is planned yet. There is a repair script which can be loaded into the database using the DB Load Utility.
It is recommended to apply this repair script as soon as possible, even the system will remain on version “11.2.4+hf.2.build.777”. It is mandatory to apply it, before an update to any newer version is started, at the latest.The steps blow explains how it is applied correctly. Those steps can be performed during the Automation Engine system is up and running, no downtime in needed.
