The production application user resides on the source database and is either the owner of the tables that you want to archive or partition, or the user that has full rights to the tables that you want to archive or partition. During the archive process, you can use the production application user to delete from the source. Alternatively, you can configure the source connection to use the staging user to delete data from the source.
The production application user typically requires the following user privileges:
Select, insert, update, and delete privileges on all application tables.
CREATE ANY TRIGGER and ALTER ANY TRIGGER. Required if triggers on application tables are owned by a different user.
SELECT ANY TABLE. Required to access the staging tables only if you use the production application user for the delete from source step.
Read-only access to the directory that contains binary files if the source data contains BFILE datatypes.
