This table is used only for server-initiated synchronization. It stores device names that are required by device tracking.
| Column | Description |
|---|---|
| device_name | VARCHAR(255). Primary key. |
| listener_version | VARCHAR(128). Not null. |
| listener_protocol | INTEGER. Not null. |
| info | VARCHAR(255). Not null. |
| ignore_tracking | CHAR(1). Not null. |
| source | VARCHAR(255). Not null. |
device_name A name given to the device. This name is extracted from the operating system unless you specify a name using the dblsn -e option.
listener_version This field contains the SQL Anywhere Studio version number for the installed software on the device. Changing this value does not affect the operation of the software, but may be useful for diagnostic purposes.
listener_protocol This value is 0 for Listeners from versions of SQL Anywhere Studio prior to 9.0.1, and Listeners started with the -s option; 1 for post-9.0.0 Palm Listeners; and 2 for post-9.0.0 Windows Listeners started without -s.
info Information about the device. This field is populated if you provide information using the dblsn -f option.
ignore_tracking If this is y, tracking information is not written to the row. If it is n, tracking information is written to the row.
source 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.
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. For more information, see Using device tracking with Listeners that don't support it.
If you want to stop automatic tracking, set override_tracking to y. In this case, it is also recommended that you use a source name other than tracking. For more information, see ml_set_device.
