SQL Server 代理作业超时

发布于 2024-08-08 09:40:17 字数 125 浏览 4 评论 0原文

我刚刚有一个计划的 SQL Server 作业运行时间比正常情况要长，我真的可以通过设置超时来在一定时间长度后停止它。

我可能对此有点盲目，但我似乎找不到一种为作业设置超时的方法。有谁知道该怎么做？

谢谢

我们做了类似下面的代码作为夜间作业处理子系统的一部分 - 它比现实中的实际情况更复杂；例如，我们正在处理多个相互依赖的作业集，并从配置表中读取作业名称和超时值 - 但这捕获了这个想法：

    DECLARE @JobToRun NVARCHAR(128) = 'My Agent Job'
DECLARE @dtStart DATETIME = GETDATE(), @dtCurr DATETIME
DECLARE @ExecutionStatus INT, @LastRunOutcome INT, @MaxTimeExceeded BIT = 0
DECLARE @TimeoutMinutes INT = 180 

EXEC msdb.dbo.sp_start_job @JobToRun
SET @dtCurr = GETDATE()
WHILE 1=1
BEGIN
    WAITFOR DELAY '00:00:10'
    SELECT @ExecutionStatus=current_execution_status, @LastRunOutcome=last_run_outcome 
    FROM OPENQUERY(LocalServer, 'set fmtonly off; exec msdb.dbo.sp_help_job') where [name] = @JobToRun
    IF @ExecutionStatus <> 4
    BEGIN -- job is running or finishing (not idle)
        SET @dtCurr=GETDATE()
        IF DATEDIFF(mi, @dtStart, @dtCurr) > @TimeoutMinutes
        BEGIN   
            EXEC msdb.dbo.sp_stop_job @job_name=@JobToRun                   
            -- could log info, raise error, send email etc here
        END
        ELSE
        BEGIN
            CONTINUE
        END
    END
    IF @LastRunOutcome = 1  -- the job just finished with success flag
    BEGIN
        -- job succeeded, do whatever is needed here
        print 'job succeeded'                                   
    END

END

We do something like the code below as part of a nightly job processing subsystem - it is more complicated than this actually in reality; for example we are processing multiple interdependent sets of jobs, and read in job names and timeout values from configuration tables - but this captures the idea:

    DECLARE @JobToRun NVARCHAR(128) = 'My Agent Job'
DECLARE @dtStart DATETIME = GETDATE(), @dtCurr DATETIME
DECLARE @ExecutionStatus INT, @LastRunOutcome INT, @MaxTimeExceeded BIT = 0
DECLARE @TimeoutMinutes INT = 180 

EXEC msdb.dbo.sp_start_job @JobToRun
SET @dtCurr = GETDATE()
WHILE 1=1
BEGIN
    WAITFOR DELAY '00:00:10'
    SELECT @ExecutionStatus=current_execution_status, @LastRunOutcome=last_run_outcome 
    FROM OPENQUERY(LocalServer, 'set fmtonly off; exec msdb.dbo.sp_help_job') where [name] = @JobToRun
    IF @ExecutionStatus <> 4
    BEGIN -- job is running or finishing (not idle)
        SET @dtCurr=GETDATE()
        IF DATEDIFF(mi, @dtStart, @dtCurr) > @TimeoutMinutes
        BEGIN   
            EXEC msdb.dbo.sp_stop_job @job_name=@JobToRun                   
            -- could log info, raise error, send email etc here
        END
        ELSE
        BEGIN
            CONTINUE
        END
    END
    IF @LastRunOutcome = 1  -- the job just finished with success flag
    BEGIN
        -- job succeeded, do whatever is needed here
        print 'job succeeded'                                   
    END

END
