transactions - MSDTC 事务超时问题

Question

我现在面临 MSDTC 事务超时问题。由于历史原因，我们仍然有很多遗留代码通过 C++ ODBC 运行 DB 操作，并且连接默认升级为 MSDTC。问题是当我尝试执行一个超过 1 分钟的冗长操作时，事务将由 MSDTC 自动处理，我发现可以通过组件服务管理工具更改此值，但是，我能否以编程方式设置此超时值？

任何引用将不胜感激，提前致谢。

我叫 Tony，我在 Microsoft 支持的分布式事务团队工作。我已阅读您的帖子，相信我了解您的要求。这是我为在组件级别进行更改而编写的代码示例。希望对您有所帮助:

//Connect to the machine
COMAdmin.COMAdminCatalog m_objAdmin1 = new COMAdmin.COMAdminCatalog();
m_objAdmin1.Connect(System.Environment.MachineName.ToString());

//Get a list of COM+ Applications
COMAdmin.COMAdminCatalogCollection objApplications = (COMAdmin.COMAdminCatalogCollection)m_objAdmin1.GetCollection("Applications");
objApplications.Populate();
COMAdmin.COMAdminCatalogObject appToFind = null;

//Find the application you want to change
for (int i = 0; i < objApplications.Count; i++)
{
    appToFind = (COMAdmin.COMAdminCatalogObject)objApplications.get_Item(i);

    if (appToFind.Name.ToString() == "MSTEST")
    {
        break;
    }
}


 //Now find the component in the application you wish to change
COMAdmin.COMAdminCatalogCollection objComponents = (COMAdmin.COMAdminCatalogCollection)objApplications.GetCollection("Components", appToFind.Key);
objComponents.Populate();
COMAdmin.COMAdminCatalogObject ComponentsToFind = null;

for (int i = 0; i < objComponents.Count; i++)
{
    ComponentsToFind = (COMAdmin.COMAdminCatalogObject)objComponents.get_Item(i);

    if (ComponentsToFind.Name.ToString() == "tdevere_vb6_com.Tdevere")
    {
        break;
    }
}

//Set the Transaction support option
//Enable the overide option
//Set the new value for the time out option
COMAdmin.COMAdminTransactionOptions temp = (COMAdmin.COMAdminTransactionOptions )ComponentsToFind.get_Value("Transaction");
ComponentsToFind.set_Value("Transaction", COMAdmin.COMAdminTransactionOptions.COMAdminTransactionRequiresNew);
ComponentsToFind.set_Value("ComponentTransactionTimeout", 120);
ComponentsToFind.set_Value("ComponentTransactionTimeoutEnabled", true);

//Make sure to save the changes
objComponents.SaveChanges();
objApplications.SaveChanges();
