您好，我正在尝试在不同的服务器上将 3 个表与 2 个数据库同步。
表格有点大，共有 5029513 行，数据大小为 1.45gb:
当我尝试将客户端和服务器与空表数据同步时，它成功，因此连接没有任何问题。
我试图让脚本在命令超时设置为 36000 秒的情况下运行一整夜，但是当我醒来时，我收到了一个连接超时异常。

我该怎么做才能使这项工作正常进行？ 客户端是 'SQL Server 2008' 而服务器是 'SQL Server 2005 SP3'
这是我正在使用的代码，它在 serverProvision.Apply() 处停止:
class Program
{
static void Main()
{
//setup scope name
const string scopeName = "EmailSyncDBScope";
//setup the connections
var serverConn = new SqlConnection(ConfigurationManager.ConnectionStrings["ServerConnection"].ConnectionString);
var clientConn = new SqlConnection(ConfigurationManager.ConnectionStrings["ClientConnection"].ConnectionString);
var serverProvision = new SqlSyncScopeProvisioning(serverConn);
serverProvision.CommandTimeout = int.Parse(ConfigurationManager.AppSettings.Get("SyncCommandTimeout"));
//provision server
if (!serverProvision.ScopeExists(scopeName))
{
var serverScopeDesc = new DbSyncScopeDescription(scopeName);
// add table
var emailTableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable("Email", serverConn);
var emailMessageTableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable("Email_Message", serverConn);
var emailStatusTableDesc = SqlSyncDescriptionBuilder.GetDescriptionForTable("Email_Status", serverConn);
serverScopeDesc.Tables.Add(emailTableDesc);
serverScopeDesc.Tables.Add(emailMessageTableDesc);
serverScopeDesc.Tables.Add(emailStatusTableDesc);
serverProvision.PopulateFromScopeDescription(serverScopeDesc);
//apply the scope definition
Console.WriteLine("Applying server provision.");
serverProvision.Apply();
}
//provision client
var clientProvision = new SqlSyncScopeProvisioning(clientConn);
clientProvision.CommandTimeout = int.Parse(ConfigurationManager.AppSettings.Get("SyncCommandTimeout"));
if (!clientProvision.ScopeExists(scopeName))
{
//get scope description from server
var scopeDesc = SqlSyncDescriptionBuilder.GetDescriptionForScope(scopeName, serverConn);
clientProvision.PopulateFromScopeDescription(scopeDesc);
//apply the scope definition
Console.WriteLine("Applying client provision.");
clientProvision.Apply();
}
// create the sync orchestrator
var syncOrchestrator = new SyncOrchestrator();
//setup providers
var localProvider = new SqlSyncProvider(scopeName, clientConn);
var remoteProvider = new SqlSyncProvider(scopeName, serverConn);
syncOrchestrator.LocalProvider = localProvider;
syncOrchestrator.RemoteProvider = remoteProvider;
Console.WriteLine("Getting sync direction order settings.");
var syncDirectionOrder = GetSyncDirectionOrder(ConfigurationManager.AppSettings.Get("SyncDirectionOrder"));
// set sync direction
syncOrchestrator.Direction = syncDirectionOrder;
// execute the synchronization process
SyncAndEmail(syncOrchestrator, bool.Parse(ConfigurationManager.AppSettings.Get("SendMail")));
}
private static SyncDirectionOrder GetSyncDirectionOrder(string syncDirectionOrder)
{
SyncDirectionOrder returnValue;
switch (syncDirectionOrder)
{
case "Upload" :
returnValue = SyncDirectionOrder.Upload;
break;
case "Download" :
returnValue = SyncDirectionOrder.Download;
break;
case "UploadAndDownload" :
returnValue = SyncDirectionOrder.UploadAndDownload;
break;
case "DownloadAndUpload" :
returnValue = SyncDirectionOrder.DownloadAndUpload;
break;
default:
returnValue = SyncDirectionOrder.Upload;
break;
}
return returnValue;
}
private static void SyncAndEmail(SyncOrchestrator syncOrchestrator, bool sendEmail)
{
Console.WriteLine("Syncronizing.");
var syncStats = syncOrchestrator.Synchronize();
var content = new StringBuilder();
content.Append("<p><h2>Syncronization report:</h2></p>");
content.Append("<strong>Start Time:</strong> " + syncStats.SyncStartTime + "</br>");
content.Append("<strong>Total Changes Uploaded:</strong> " + syncStats.UploadChangesTotal + "</br>");
content.Append("<strong>Total Changes Uploaded and Applied:</strong> " + syncStats.UploadChangesApplied + "</br>");
content.Append("<strong>Total Changes Uploaded and Failed:</strong> " + syncStats.UploadChangesFailed + "</br>");
content.Append("<strong>Total Changes Downloaded:</strong> " + syncStats.DownloadChangesTotal + "</br>");

content.Append("<strong>Total Changes Downloaded and Failed:</strong> " + syncStats.DownloadChangesFailed + "</br>");
content.Append("<strong>Complete Time:</strong> " + syncStats.SyncEndTime);
if (sendEmail)
{
var emailModel = new EmailModel
{
MailTo = ConfigurationManager.AppSettings.Get("MailTo").ToLower(),
MailFrom = ConfigurationManager.AppSettings.Get("MailFrom").ToLower(),
Subject = ConfigurationManager.AppSettings.Get("MailSubject"),
Content = content.ToString()
};
var mailClient = new MailServiceClient();
Console.WriteLine("Sending email.");
mailClient.SendFromExtreme(emailModel.MailFrom, new[] { emailModel.MailTo }, emailModel.Subject, emailModel.Content, "", new[] { "Syncronization" }, EmailType.ControlTask, 0, false);
}
}
}
最佳答案
您可以直接在 SqlCommand 上设置 CommandTimeout。
