ContinueDownload (cd) extended option

Restarts a previously failed download.

Syntax
cd={ ON | OFF }; ...
Remarks

If MobiLink fails during a download it does not apply any of the download data to the remote database. However, it stores the part of the download it did receive in a temporary file on the remote device, so that it can be restarted later. When you set the extended option cd=on, dbmlsync restarts the download and attempts to download the part of the previous download that it did not receive. If it is able to download the remaining data, it applies the complete download to your remote database.

If there is any new data to be uploaded when you set -cd=on, the restartable download fails.

You can also specify restartable downloads for SQL Anywhere remote databases with the -dc option or with the sp_hook_dbmlsync_end hook.

This option has a short form and long form: you can use cd or ContinueDownload.

You can also store extended options in the database. For more information about dbmlsync extended options, see Introduction to dbmlsync extended options.
