Hello
I am trying to retrieve data from Essbase to PBI.
For this i am using the Harry Gates method (thanks to him! 🙂 )
When the Essbase has been newly started, i can retrieve my data very fast (less than 30 sec).
The issue, is that if afterwards I try to retrieve the same MDX or something different, i got a timeout despite i set the timeouts high. And, the Essbase server gets blocked, busy with the several XMLA requests he received. This of course does not make the Essbase admin happy. I could not find answers elsewhere, so here are my questions:
- when we execute an XMLA statement in PBI, when is the query executed: each time an object changes in PBI, or only when the refresh button is pressed?
- How is it possible that this XMLA script generates several requests to Essbase?
- I thought that when the query is done successfully the process is then stopped automatically. Apparently I an not right. Does anybody knows if it is a PBI issue or Essbase issue?
- I set the same timeout in the XMLA as in the registery. So I don t think the problem comes from here then.
Please find below the query i am using in PBI. It is an MDX query (below in bold) embededd in a XMLA script, embededd into an M query. This query works fine when the Essbase server has been rebooted, but if i start a second time this query i already get a timeout, and then the server keeps on being busy / do not answer. Our server has enough power for the SmartView retrievals, so i don t think the hardware is a problem.
Thanks in advance for your support / hints!
Best regards
Ghuiles
