Reporting errors

Since errors can disrupt the natural progression of the synchronization process, it can be difficult to create a log of errors and their resolutions. The report_error script provides a means of accomplishing this task. The MobiLink server executes this script whenever an error occurs. If the handle_error script is defined, it is executed immediately prior to the reporting script.

The parameters to the report_error script are identical to those of the handle_error script, except that the report_error script can not modify the action code. Since the value of the action code is that returned by the handle_error script, this script can be used to debug error-handling problems.

This script typically consists of an insert statement, which records the values, perhaps with other data, such as the time or date, in a table for later reference. To ensure that this data is not lost, the MobiLink server always runs this script in a separate transaction and automatically commits the changes when this script completes.

See report_error connection event.


The following report_error script, which consists of a single insert statement, adds the script parameters into a table, along with the current date and time. The script does not commit this change because the MobiLink server always does so automatically.

  {ml s.action_code},
  {ml s.error_code},
  {ml s.error_message},
  {ml s.username},
  {ml s.table} );
