Dear all,

Based on the Shani's comment, I'm sending the apache tomcat7 logs files as
we proposed in order to investigate possible memory leak in the window
version of CEP.
Also, keep us informed regarding the findings of the new work item
https://jira.fiware.org/browse/DATA-1330 since it is quite urgent for our
implementation.

Thanks in advance

This item is closed since a work item https://jira.fiware.org/browse/DATA-1330 will fix problems with the DOCKER image.

1. Yes send the log to shani@il.ibm.com.
2. Work on docker image still pending.
Any specific input you have for that is appreciated.
3 I am happy that direct work with Tomcat works. Per resources to be used, that is something you can try and err to fit best your application - meaning complexity of your rules, and events load. The CEP documents have some suggestions, but it clearly is something that cannot be one answer for all.

Hope this helps, more to come.
Thanks,

Hi all,

To problem in Linux installation and the erroneously docker script remains.

Moreover, we try to deploy the war files into a Apache tomcat 7 in a
windows machine, we configure it properly and the application works as we
expect.
In windows we haven't faced any problem during the installation. One issue
to this installation is that after some hour the apache tomcat process
terminates with a log reference to memory leaks.

Could you provide us the minimum requirements for a windows installation
for CEP? (RAM,CPU etc)
It will be easy for you to provide you with the log of Apache Tomcat 7
server?

Thanks,

Hi Javier, Zahos,

Dear Javier,and Zahos,

Here is the response from Uri ( the new GE owner):

"Consulting with my peers here (I joined the team recently and still catching up), the reason for the problems may be rooted in the installation process of the docker image. Please see here:
http://proactive-technology-online.readthedocs.org/en/v4.4.1/Proton-InstallationAndAdminGuide/index.html
While we work on fixing the docker image problem (of which you are some of the early adopters), it seems that your problem has a work around as you have described in your mail. Sorry that the process is not sufficiently automated and inconvenient - something that certainly needs to be fixed.
Another possibility for slow performance would be insufficient compute resources assigned to the image. Can you please share with me the resources allocated to the installed image? RAM, DISK, CPU? Small RAM would be a big problem for Java apps such as Proton causing unbearable delays. Several GBs should be used.
So, to summarize:
1 - validate your installation procedure with the guide
2 - check again the resources allocated to the image, and report back.
3 - let us review this docker image and revise it through a problem ticket on our system.
I hope that you can still get your work done and meet your deadline inspite of these inconveniences.
Uri"

Hope this helps with the problem.
