論壇上見到的，記錄一下，以備後用
Process p = Runtime.getRuntime().exec( MProperties.DS_EXE_PATH + "/dsjob -run -wait -param lowDate=" + lowDate + " -param highDate=" + highDatePlusOne + " -param dsOutDir=" + MProperties.DS_OUT_DIR + " -param IDB_user=" +MProperties.IDB_USER + " -param IDB_pass=" +
MProperties.IDB_PASS + " " + MProperties.DS_PROJECT + " " + MProperties.DS_JOB);
p.waitFor();
return p.exitValue() == 0;

另外如果有RTI，更好的方法如下：
The best way for this to be accomplished is by using the RTI (Real Time Integration) capabilities that we added in 7.x. This allows you to fully expose a DataStage job as a service, to be then invoked via several different mechanisms, depending on your needs....

.....the job can be exposed as a classic web service, using SOAP over HTTP...we generate and publish the WSDL for this within RTI...

....the job can be exposed via our EJB binding and called appropriately

....the job can be exposed for contact via JMS, and either passed a text message or SOAP envelope....

Not only can you simply pass job parameters via this architecture, you can actually have the entire transformation job itself (columns on the ultimate input and output links) passed and returned to your calling client.

Additionally, the entire job control API, which you may already be familiar with in its API or command line implementations, has been exposed as a set of methods available via Web Services.
主要就是通過將job包裝為web service或EJB或JMS來調(diào)用，可以傳參數(shù)，還可以將整個job本身（最終的輸入和輸出鏈接）作為參數(shù)傳遞或者返回到調(diào)用的客戶端。
