Ignite Servlet with Tomcat: Memory
Hello,
I have integrated the Ignite servlet with Tomcat. It is running besides my own
controller class and works fine.
But I wonder how I can increase the heap memory assigned to Ignite. When I
start my web container Ignite claims it is using 186Mb as memory. Can somebody
please give me a hint of how to increase that?
Or is Ignite somehow taking it's memory somehow from Tomcat?
Rgds,
Uwe

thanks Ilya for the quick reply.
So I guess that when I increase the memory for tomcat, then the Ignite process
running within my tomcat based web application will take a share of it.
It is not that I have large memory requirements, but I want to code the
application to be configurable as much as possible.
Btw: I have started using Ignite about two month ago. After some first trials
with Java and JDBC, I have done some research on using Ignite with the Pentaho
PDI (ETL) tool. And then also setup a java service to read from Kafka and
store the data in Ignite. My latest attempt is to include Ignite as the
caching layer in this webapp.
I will try the link this and let you know.
Thanks again,
Uwe

Hello Ilya,
I have added the listener for Ignite like this to my web.xml configuration:
<listener>
<listener-class>org.apache.ignite.startup.servlet.ServletContextListenerStartup</listener-class>
</listener>
with followinf parameters:
<init-param>
<param-name>IgniteConfigurationFilePath</param-name>
<param-value>config/ignite-config.xml</param-value>
</init-param>
When I run tomcat I get following output:
