Used to list database transaction details as they occur. The transaction log can be useful for isolating the causes of unexpected interactions between OpenUtilities Substation and the database. Processing slows significantly, however. Transaction details include SQL statements (generated by OpenUtilities Substation or an application or submitted by the user in the SQL Window), OpenUtilities Substation database requests, and status and error messages issued by the database software. OpenUtilities Substation database requests are listed in UPPERCASE.
