Run the MobiLink server in a server farm

  • Separately licensed component required   Running the MobiLink server in a server farm is a feature of the MobiLink high availability option, which requires a separate license. See Separately licensed components.

A MobiLink server farm is an environment where there is more than one MobiLink server synchronizing the same set of remote databases with the same consolidated database. This is often required for large scale deployments or for fail-over capability. These MobiLink server farm deployments may require the use of the Relay Server if an HTTP communication link is used. For TCP-based streams, a TCP load balancer should work. When using multiple servers, restartable download does not work.

 Enable shared server state
  • If you are using the Notifier with server-initiated synchronization, use the -lsc option to specify the local server connection settings. These settings are passed to the other servers in the farm so that they can connect to each other to share the handling of notifications. For example, if running on host farm_host22:

    mlsrv12 -x tcpip(port=3245) -zs server5 -lsc tcpip(host=farm_host22;port=3245) -c ...
