问题
I am new to ODI. While working i ODI Project, I am facing one issue.
I have 10 mappings In ODI12c,and all are using same target table,but due to some performance issue, I want that at a time only max 2 users can Execute mappings(Max 2 mappings), since they are using same target table. If more then 2 user uses that same target then it should not execute.
How should I implement this in ODI12c?
回答1:
You can do something, but not exactly what you said. You can setup and option called "Concurrent Execution Controller" and tell a scenario to wait until it's previous execution it's finished.
So, you can do the next:
1.create a package
2.create scenarios for all the mappings
3.create a variable
2.inside the package call a scenario (no matter what scenario) and at the scenario name, put the variable (see image below)
3.generate scenario for package
4.double click on the scenario of the package and choose "Limit Concurrent Executions" then choose Wait to Execute and then setup the Wait Polling interval to X seconds to wait
5.execute the package scenario and when the variable it's prompted, complete the name of the mapping you want to be executed
Please tell me if you need more info.
