ms同步内存不足异常

Question

我正在尝试同步大小> 4GB的SQL Server数据库。 内存不足异常。 尝试使用MemoryDataCacheSize和ApplicationTransactionSize。 没有成功 代码在这里给出。

    public static long BatchSize = 500000;
    public static uint MemorySize = 4000000000;
    public void Sync(ServerSyncHelper server)
    {
        try
        {
            SqlConnection clientConn = DBConnection;
            SqlConnection serverConn = server.DBConnection;
            SyncOrchestrator syncOrchestrator = new SyncOrchestrator();
            var localProvider = new SqlSyncProvider(ScopeName, clientConn);
            localProvider.MemoryDataCacheSize = MemorySize;
            localProvider.ApplicationTransactionSize = BatchSize;
            syncOrchestrator.LocalProvider = localProvider;
            var remoteProvider = new SqlSyncProvider(server.ScopeName, serverConn);

            remoteProvider.ApplicationTransactionSize = BatchSize;
            remoteProvider.MemoryDataCacheSize = MemorySize;
            remoteProvider.ChangesApplied += new EventHandler<DbChangesAppliedEventArgs>(RemoteProvider_ChangesApplied);
            syncOrchestrator.RemoteProvider = remoteProvider;
            syncOrchestrator.Direction = SyncDirectionOrder.UploadAndDownload;
            ((SqlSyncProvider)syncOrchestrator.LocalProvider).ApplyChangeFailed += new EventHandler<DbApplyChangeFailedEventArgs>(ApplyChangeFailed);
            SyncOperationStatistics syncStats = syncOrchestrator.Synchronize();
            LogWriter.Write("Start Time: " + syncStats.SyncStartTime);
            LogWriter.Write("Total Changes Uploaded: " + syncStats.UploadChangesTotal);
            LogWriter.Write("Complete Time: " + syncStats.SyncEndTime);
        }
        catch (Exception ex)
        {
            LogWriter.Write(ex);
        }
    }

您的进程正在尝试分配过多的内存（这由MemoryDataCacheSize控制）。 在此处查找有关您要执行的操作的更多信息 。
