How to increase heap size in solr or tomcat?
solr, tomcat
Solution
Find the command that you use to start the server that runs Solr (Tomcat or Jetty) and add java heap size options to it - e.g. -Xmx500m will set a max heap size of 500 MB, and -Xms300m will set an initial heap size of 300 MB.
For Tomcat, find catalina.sh, open it up and find the line that sets CATALINA_OPTS. Add the options for -Xms and -Xmx to that line. In Windows you don't put them in quotes, and in Linux you do.
