hai in data stage we have option like "Allow multiple instance".If i will click on this button and subsequently suppose if we try to run a job which is in running stage ,and if we have a file as a intermediate stage in job.how it will make impact on the job.

please let me know about the impacts on job in this situation.


Thanks

The Director online help has good information on Multi-Instance options. Biggest thing is the job needs to be designed with MI support in mind, particularly how resources are shared (or not).

Does "hai" at the beginning of your question mean that you understand?

The operating system only allows one writer at a time to a file. Given that fact, you can figure out the answer to your question.

If intermediate stage has a sequential file(buffer),i/p and o/p is OLDEB stage,and we are trying to run the job whose status is running.In this case what will be the impact.

Failure. You can't run a job whose status is 'Running'.

Use "DSJobInvocationId" as part of the file name, that way your job can run in multiple instances simultaneously.
