ml_device_address


This table is used only for server-initiated synchronization. It stores addressing information that is required by device tracking.

Column

Description

device_name

VARCHAR(255). Primary key. Foreign key references dbo.ml_device. Not null. This column stores the name of the device. This name is extracted from the operating system unless you specify a name using the dblsn -e option.

medium

VARCHAR(255). Primary key. Not null. For UDP, this is _UDP_. Otherwise, it is the network provider ID.

address

VARCHAR(255). Not null. For UDP, this is ip:port-number, where ip is an IP address or host name. For SMS, this is the phone number.

activeVARCHAR(1). Not null. This is y for active, and n otherwise. A DeviceTracker gateway may deactivate a UDP channel if it is unresponsive and there is a fallback SMS delivery path.
last_modifiedTimestamp. Not null. Default timestamp. This stores the datetime when this row was last modified.
ignore_trackingVARCHAR(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.
sourceVARCHAR(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. Unless it is set to tracking, the value in this column does not affect the operation of the software.
Remarks

The MobiLink system tables ml_device, ml_device_address, and ml_listening contain 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 to this system 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 ignore_tracking to y. In this case, it is also recommended that you use a source name other than tracking.
