SQL Server維護計划任務和完成

Question

我有一個看起來像這樣的維護計划...

Client 1 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client
Client 2 Import Data (Success) -> Process Data (Success) -> Post Process (Completion) -> Next Client
Client N ...

導入數據和流程數據正在調用作業，而后流程是Execute Sql任務。 如果導入數據或過程數據失敗，它將轉到下一個客戶端導入數據...

導入數據和過程數據都是包含使用內置SQL日志記錄提供程序的SSIS包的作業。

我對當前配置的期望是：

1. 客戶端1導入數據運行：失敗->客戶端2導入數據| 成功過程數據
2. 流程數據運行：失敗->客戶端2導入數據| 成功后流程
3. 后期處理運行：完成->成功或失敗->下一個客戶端導入數據

不過，這不是我在日志中看到的內容……我看到幾個“客戶端導入數據” SSIS日志條目，然后是幾個“后期處理”日志條目，然后又回到“客戶端導入數據”！ 啊！

我究竟做錯了什么？ 我不認為“客戶端1導入數據”的“成功”部分會開始，直到...成功完成。 日志似乎表明並非如此...

我真的需要這些任務是連續的而不是並發的。 這可能嗎？

謝謝！

Answer 1

嘗試將序列容器放在需要成組執行的任務周圍。

Answer 2

對我來說，解決方法最終不是使用內置的“執行SQL Server代理作業任務”，而是使用“執行T-SQL語句任務”，而是調用直到完成才阻塞的存儲過程。

成功的秘訣:-)

CREATE PROCEDURE [dbo].[SQLJob_RunBlocking]
(
    @JobName SYSNAME
)
AS
BEGIN
    -- running a job returns before the job is complete
    -- this procedure will run the job and loop until its status is complete
    SET NOCOUNT ON;

    DECLARE @JobStatus INT;

    -- start job
    EXECUTE msdb.dbo.sp_start_job @job_name = @JobName;

    -- loop until status is complete
    WHILE ISNULL(@JobStatus, 0) != 4 BEGIN
        WAITFOR DELAY '00:00:01';

        EXECUTE dbo.SQLJob_GetStatus @job_name = @JobName, @select_data = 0, @execution_status = @JobStatus OUTPUT;
    END

和...
