This table is used only for server-initiated synchronization. It maps a MobiLink user name to a device name for device tracking.
VARCHAR(128). Primary key. Not null. This is the name you use to address notification. This column can be populated in one of three ways:
VARCHAR(255). Foreign key references dbo.ml_device. Not null. This column stores the name given to the device. This name is extracted from the operating system unless you specify a name using the dblsn -e option.
VARCHAR(1). Not null. This is y for an active Listener; otherwise it is n. This field is set when you use the dblsn option -t, or you can manually set it with stored procedures.
|ignore_tracking||VARCHAR(1). Not null. If this is y, tracking information is not written to the row. If it is n, tracking information is written to the row.|
|source||VARCHAR(255). Not null. This is tracking if the row was created by automatic device tracking. Otherwise, it is blank unless you change it using stored procedures to add information about where the data in this row came from. The value in this column does not affect the operation of the software.|
The MobiLink system tables ml_device, ml_device_address, and ml_listening contain tracked information about devices for server-initiated synchronization. DeviceTracker gateways use this information to address target devices by MobiLink user name.
In most cases, you should not need to alter these tables. However, if your device does not support device tracking or if you want to override device tracking for troubleshooting purposes, you can add or delete rows in this table using pre-defined stored procedures. See Using device tracking with Listeners that don't support it.
If you want to stop automatic tracking, set override_tracking to Yes. In this case, it is also recommended that you use a source name other than tracking.
