Database
The eKERNEL application is the only application that communicates directly with the
databases. Every external application receives its configuration from eKERNEL.
There are two databases. One is named Messenger_CFG.mdb, and another is named
Messenger_data.mdb. Both databases are in Microsoft Access 2000 format, and are
processed through applications written in Microsoft Visual Studio 6.0 (Visual Basic and C+
+).
In release 4.0, the Messenger_DATA database can also reside on SQL Server 2005 Express,
SQL Server 2000 Desktop Engine (MSDE), or an external SQL 2000 or 2005 server.
The Messenger_CFG.mdb contains several tables, and defines the configuration of the DECT
Messenger software. These tables determine the behavior of the product.
The Messenger_data.mdb contains several tables, and are an internal work space of DECT
Messenger. Some models, such as eKERNEL, access this database heavily. Avaya
recommends that you avoid using the data database, except for problem determination and
recovery services.
TCP Connections
The eKERNEL acts as a TCP Server, and typically listens to several ports.
You can configure the TCP clients in the configuration database.
The status of each connection is visible on the screen of the eKERNEL application. In normal
operation, an active connection is indicated by the color green. A client that is not connected
is indicated by the color yellow. Other colors indicate an intermediate state or an error
condition.
Logging
You can log every event to ASCII log files and on the screen. The on-screen buffer is limited
to 100 records. To see details, double-clicking on the log records. The log files are commonly
stored in the directory specified in the CFG_Log_path_str field of the eKERNEL_site table.
If CFG_Log_path_str = C:\SOPHO Messenger@net, all log files are stored in the C:\SOPHO
Messenger@Net\log\eKERNEL directory. Each day a new log file is created at midnight.
