i have multiple databases(sql server 2008) each with multiple tables,each database at different servers to be synced at real time changes

They should be synced at all servers,update on any table at any server should be synced.In short,all tables should have same data at all times.

DbSyncScopeDescription scopeDesc = new DbSyncScopeDescription("Scope");

        // get the description of the table from SyncDB dtabase
        DbSyncTableDescription tableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable("table1", serverConn);
        DbSyncTableDescription tableDesc1 = SqlSyncDescriptionBuilder.GetDescriptionForTable("table2", serverConn);

        // add the table description to the sync scope definition

        // create a server scope provisioning object based on the Scope
        SqlSyncScopeProvisioning serverProvision = new SqlSyncScopeProvisioning(serverConn, scopeDesc);

        // skipping the creation of table since table already exists 

        //Create new selectchanges procedure for our scope

        // Start the provision-USE ONLY ONCE

        //Get definition for Scope 
        DbSyncScopeDescription scopeDescription = SqlSyncDescriptionBuilder.GetDescriptionForScope("Scope", serverConn);

        //Provise NODE using this definition
        SqlSyncScopeProvisioning productionProvisioning = new SqlSyncScopeProvisioning(serverConn2, scopeDescription);
        SqlSyncScopeProvisioning productionProvisioning2 = new SqlSyncScopeProvisioning(serverConn3, scopeDescription);
        // Start the provision-USE ONLY ONCE

        SyncOrchestrator syncOrchestrator = new SyncOrchestrator();

        //Specify source database
        syncOrchestrator.RemoteProvider = new SqlSyncProvider("Scope", serverConn, null, null);

        //Specify production database
        syncOrchestrator.LocalProvider = new SqlSyncProvider("Scope", serverConn2, null, null);

        syncOrchestrator.LocalProvider = new SqlSyncProvider("Scope", serverConn3, null, null);

    public void SyncFn(SyncOrchestrator syncOrchestrator)
        // execute the synchronization process
        SyncOperationStatistics syncStats = syncOrchestrator.Synchronize();
        Initiatedtxtbx.Text = syncStats.SyncStartTime.ToString();
        ChngesUptxtbx.Text = syncStats.UploadChangesTotal.ToString();
        ChngesDwntxtbx.Text = syncStats.DownloadChangesTotal.ToString();
        Completntxtbx.Text = syncStats.SyncEndTime.ToString();

It works with 1 same table in 2 databases.

All have identity increment as primary key. data in table1 is around 20000 and table 2 300000.The first instance of SyncFn(syncOrchestrator) itself keeps running indefinitely without errors, cant understand whether its processing or stuck somewhere;i changed only 1 row to check sync.

what options do i have ?what am i missing?
