Manage Task flows using Edx

[#1]

Hi all,

I'm a newbie and I'm using QlikView Version:10.00.9086.7 with Publisher.

I need to call in sequence, after the previous success, n-task using the parameters received by HTTP- GET (I developed a java servlet)

and sharing parameters between tasks.

I don't know when the requests come so I need to manage concurrent requests.

For every request I have to call a sequence of task (always the same) but giving them different param value.

(...I'm using qvw document to do ETL)

I receive a HTTP-GET (ex, shop=1&month=01), I call the task1_edx using the POST concatenating a and b value

Parameter Input: shop:1 - month:01,

...shop:2 - month:01....

ex:

<Global method="RequestEDX" key="YOUR_EDX_KEY">

            <i_TaskIDOrTaskName>MyTask</i_TaskIDOrTaskName>

            <i_Password>EDX_PWD</i_Password>

            <i_VariableName>testvar</i_VariableName>

            <i_VariableValueList>

            <string>1_10</string> (I'll use subfield...)

            </i_VariableValueList>

</Global>

Flow:

Document1 -task EDX with variable:shop1_month1

-->(success)-->

Document2-task EDX with same variable:shop1_month1

-->(success)-->

Document3-task EDX with same variable:shop1_month1.....

• Can I use multiple <i_VariableName>, <i_VariableValueList>?
• Can I pass parameters between tasks?

I want to call the first task with my servlet, than using dependencies and trigger for the other three task but I need to pass the initial variable between them.

It seems that it is not possible.

• Can I call at the same time the same task using different variable value or I need to create as many task of my document as the possible value I can receive?

(Document1 -task_shop1, Document1 -task_shop2, Document1 -task_shop3....)

• Call at the same time different task but referred to the same document, is it safe?

If I can't pass variable between tasks I can make my four calls in my servlet

but I need to test the status value in order to call the next task.

I need to poll while TaskIsAlreadyRunning (3) before start with the next EDX Call.

Do you have any suggestions or comments?

Thanks in advance

Mary
