My apologies as I didn't read the question thoroughly. The query will tell you the version of Oracle you are currently running, but that doesn't answer your question of support for Standard vs. Enterprise. To my knowledge there is no difference from an OnBase perspective of which edition of Oracle you are using. The following link shows a matrix of the features available between the different editions of Oracle (link). Some concerns about the differences between Standard vs. Enterprise come into play when you are considering the number of sockets (processors) available to the Oracle, High Availability options and clustering with RAC to name a few. I believe that this is a bigger question which will require a bit of discovery on your part on how the system is going to be used and requirements of the database server.
Take care.
