Who has last initialized the administrative tables, who is making all the changes, and who is expected to either commit or re-initialize (ABORT-TRANSACTION). tnBfdAdminOwner is advisory only. Before beginning a transaction, read tnBfdAdminOwner. If it is empty then proceed with the configuration. Set tnBfdAdminOwner after setting tnBfdAdminControlApply so that other users will be advised to not make changes to the Admin tables. Agent sets tnBfdAdminOwner to empty string after tnBfdAdminControlApply is set - either by user initializing or committing, or by agent timing out the uncommitted transactions (tnBfdAdminLastSetTimer).
