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