在DataStage中job不能刪除，如果試著編譯又出現如下錯誤：
Error calling subroutine: DSR_EXECJOB (Action=1); check DataStage is set up correctly in project ETUDES
(Subroutine failed to complete successfully (30107))

+

(40503) A call to an OLE server has failed, or a runtime error occured within the ole itself.

解決辦法：
1 首先運行命令：DELETE FROM DS_JOBS WHERE NAME = 'JobName'
2 再運行DS.CHECKER ，注意要運行DS.CHECKER必須要有exclusive access到project
，通過如下命令可以看到有誰還連接到了服務器：netstat -a |grep dsrpc
