Hello,
This email concerns an error I encountered while using Oracle Apex with ORDS 3.0.9 and
Tomcat 9. Specifically, I receive a "Java heap space" error when accessing the
application.
To troubleshoot the issue, I have tried to increase the maximum heap size of
the JVM using the -Xmx option in the CATALINA_OPTS environment variable. I set
this environment variable in the catalina.bat file and restarted the Tomcat
service, but the error persisted.
I have also confirmed that the CATALINA_OPTS environment variable is set
correctly by running echo %CATALINA_OPTS% in the command prompt.
I should note that I have two versions of Tomcat installed on the system - 8.5 and 9.
Everything works fine on Tomcat 8.5, but the "Java heap space" errors are
thrown on Tomcat 9.
I would appreciate any insights or guidance you can provide to help me resolve
this issue. Below are the details of the software I am using,
1. Make sure you have enough memory available (my recommendation is to
set -Xms to the same value as -Xmx, so that you see *immediately* (on
startup) if you don't have enough memory available. It doesn't help if
you need 3 hours or 3 days to run into this condition.
2. Check if your application has a memory leak (e.g. by monitoring the
memory consumption over time)
