Hello All,
We have a strange behavior with all our Dashboard on SAP 4.0 SP5 FP3 with BIWS connexions. 1 time on 10 (approx.) the BI Web Service connexion take so long. I mean in normal circonstance, it take 2 seconds, then it take 30 seconds, 1 minute and more to return the result.
We build a Jmeter scenario to find a pattern without success.
Just to help, by example it when we call this.
/dswsbobje/qaawsservices/queryasaservice/biws?cuid=AVBUa5WAagZFmFxSbw77INI&authType=secEnterprise&locale=fr_CA&timeout=60&ConvertAnyType=true
I know it depend a lot of things, and we try a lot of things too but I'm trying to isolate where it take so long.
What we do so far.
1) Close all services not needs. That means at the end it keep only
CMS, Input / Output, APS Visualization, APS Webi, WebiPS. (No need Dashboard services...on only BIWS)
2) I try to captures E2E traces but can't figure out what to check...Too much lines.
Wow!
3) One interresting test I made is try to open dashboard on production where the problem is and call BIWS on acceptance environnement where it's always fast. The result it's still slow. So, I don't think it's not the web services by itself which is slow. It's probably the CMS, the network, the disk.
We have a big environnement , we run thousand reports per day. So it's probably not the disk or the network...But we never know.
Any idea where to look ?
