The column is most likely indexed with non-Automic index
Release : 12.0, 12.1, 12.2, 12.3
Component : Automation Engine
1. Verify what index is present on the column that is already indexed with your DBA (in the example provided above, you need to verify the name of the index MQSRV is indexed with). 2. If the index is not Automic index, delete it. You can verify if it is Automic index or not by checking if the index name is present in one of the SQL statements of DBLoad utility in db folder (e.x. C:\Automic\Utility\db\oracle\12.2). For example, if your index called MQSRV_INDEX, it will not be present in any of the SQL statements in C:\Automic\Utility\db\oracle\12.2. Thus, it is non-Automic index, and needs to be deleted. 3. Once the index is deleted, restart the DBLoad Utility and proceed with the Database upgrade.
