Ping synchronization parameter

Confirms communications between the UltraLite client and the MobiLink server. When this parameter is set to true, no synchronization takes place.

Syntax

Default

Allowed values

Remarks

When the MobiLink server receives a ping request, it connects to the consolidated database, authenticates the user, and then sends the authenticating user status and value back to the client.

If the ping succeeds, the MobiLink server issues an information message. If the ping does not succeed, it issues an error message.

If the MobiLink user ID cannot be found in the ml_user system table and the MobiLink server is running with the command line option -zu+, the MobiLink server adds the user to ml_user.

The MobiLink server may execute the following scripts, if they exist, for a ping request:

begin_connection
authenticate_user
authenticate_user_hashed
authenticate_parameters
end_connection

Example

ulsync can set this parameter as an extended synchronization parameter as follows:

ulsync -c DBF=myuldb.udb "MobiLinkUid=remoteA;ScriptVersion=2;Ping=True;Stream=http"

UltraLite for C/C++ applications can set the parameter as follows:

ul_sync_info info;
// ...
info.ping = ul_true;
