Logging messages during a mediation flow
You can use the Message Logger mediation primitive to store messages that you can process later. The logged messages can be used for various purposes.
For example, you could use the logged messages for data mining or for auditing.
The Message Logger mediation primitive logs messages to a relational database using an IBM-defined database schema. It does not write to other storage mediums such as flat files. The Message Logger mediation primitive logs an XML transcoded copy of the service message object.
By default, the Message Logger logs the body section of the message. You can configure the Message Logger to log the entire message, or you can use an XPath expression to specify a part of the message to be logged.
By default, messages are logged to the Common database that is created during installation of the server.
You can create your own database and log your messages there. Or, when install your runtime product you can specify which physical database is used as the Common database.
For example, you might define the Common database as being a DB2 database.
