The tracing system includes the following storage areas:
Transaction database This is a permanent storage area for voice mail system activity. The Reporting Tool is used for extracting information from this database. For more information, see MAS - Reporting Tool.
Operation history database This is a temporary storage area for events that are generated by the voice mail system. The database is purged periodically. The Operation History Viewer is used for viewing events in this database. See MAS - Operation History Viewer Window.
Note:
Please refer to the Avaya Modular Messaging Concepts and Planning Guide for information on how to best configure the operation history database.
If the Operation History Viewer is installed on the tracing system machine, a data source is created automatically. If not, you need to select a system data source before you can use the Operation History Viewer. See MAS - OHV - Selecting a Data Source & ODBC Tracing.
Note:
If ODBC logging is enabled on the MAS, performance for the system degrades. ODBC tracing should be enabled for debugging purposes only.
