MobiLink clients

  • New remote ID   MobiLink now uses a new identifier called a remote ID to uniquely identify a remote database. Previous versions used the MobiLink user name. The remote ID is stored in the remote database. MobiLink generates a remote ID the first time a remote database synchronizes (or any time it encounters a NULL value for the remote ID). The remote ID is created automatically as a GUID, but you can set it to any string that has meaning to you. The remote ID lets the same MobiLink user synchronize multiple remote databases. In UltraLite remote databases, the remote ID is also useful for allowing multiple MobiLink users to synchronize the same remote database.

    Every script that accepts the MobiLink user name as a parameter now also accepts a remote_id parameter. The remote_id parameter is only available if you use named parameters.

    To help you change the remote ID, a new database option is added to both SQL Anywhere and UltraLite databases called ml_remote_id.


  • New file transfer functionality   New functionality helps you transfer files to remote devices using the same network path you use to synchronize data. SQL Anywhere clients can use the new mlfiletransfer utility, and UltraLite clients can use the new MLFileTransfer method. This functionality is especially useful when populating new remote databases or upgrading software. A new MobiLink event has been added to authenticate the file transfer, if desired. See:

  • SendColumnNames has changed   The SendColumnNames dbmlsync extended option and Send Column Names UltraLite synchronization parameter were previously used to upload information about remote database columns so that the MobiLink server could generate sample synchronization scripts. The creation of sample synchronization scripts has been removed (and replaced with the Create Synchronization Model wizard). SendColumnNames is now used only by direct row handling. See:

  • Simplified liveness timeout settings   Liveness timeout is now controlled by the client. A new network protocol option called timeout is introduced that replaces liveness_timeout, contd_timeout, unknown_timeout, and network_connect_timeout.

    See timeout.

  • Buffer_size enhancements   Using the buffer_size network protocol option, you can now control write buffering for TCP/IP protocols as well as HTTP body size for the HTTP protocols. The default values have also changed.

    See buffer_size.
