DataStage有他自己的調度，不過個人總覺得修改起來不怎么方便。於是偏向於在Linux下用shell調度。最近項目需要，總結了一些，備忘。有什么不對的地方，歡迎指正。
1 dsjob語法
Command Syntax:
dsjob [-authfile <authfile> | -file <file> <domain> <DataStage server> | -domain <domain> -user <user> -password <password> -server <DataStage server>] | -domain <domain> [-user <user>] -server <DataStage server>
<primary command> [<arguments>]
Valid primary command options are:
-run
-stop
-lprojects
-ljobs
-linvocations
-lstages
-llinks
-projectinfo
-jobinfo
-stageinfo
-linkinfo
-lparams
-paraminfo
-log
-logsum
-logdetail
-lognewest
-report
-jobid
-import
Status code = -9999 DSJE_DSJOB_ERROR
2 腳本示例
dsjob所在的目錄為(據實況而定)：/mistel/IBM/InformationServer/Server/DSEngine/bin/dsjob
2.1 運行job
運行job，並把日志寫在/DS/DSLogs/目錄下，每天一個新的文件。
dsjob -run -mode NORMAL -jobstatus dstage1 DD_Test >> /DS/DSLogs/job_run_` date +%Y%m%d`.log
2.2 重置job
當job的狀態為“為編譯”，“終止”等時，需要重新編譯才可以運行。
dsjob -run -mode RESET -wait dstage1 DD_Test >> /DS/DSLogs/job_init_` date +%Y%m%d`.log
更多例子（dstage1項目下的 DD_Test job）：
dsjob -run -mode NORMAL -jobstatus dstage1 DD_Test >> /DS/DSLogs/job_run_` date +%Y%m%d`.log
dsjob -report dstage1 DD_Test >> /DS/DSLogs/job_run_` date +%Y%m%d`.log
3 問題解決
3.1 dsjob：command not found
執行腳本時，可能出現dsjob命令未找到的錯誤提示，解決辦法有幾種。
3.1.1 解決一
即每次調用dsjob命令前，都把dsenv中的變量讀取一次。命令如下：
source /mistel/IBM/InformationServer/Server/DSEngine/dsenv
3.1.2 解決二
讓Linux每次登錄時自動執行3.1.1中提到的腳本。即在/etc/profile.d/custom.sh中添加這段腳本。
3.2 較完整的腳本
