    <p>There are lots of questions that ask this or a similar question.</p> <p>They all give the command that has to be executed, what I don't understand is where do I write this command. I want to permanently increase the heap space for my tomcat apps.</p> <p>I read this page <a href="http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html" rel="noreferrer"><a href="http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html" rel="noreferrer">http://javahowto.blogspot.com/2006/06/6-common-errors-in-setting-java-heap.html</a></a> and it says under the Tomcat section </p> <blockquote> <p>Stop Tomcat server, set environment variable CATALINA_OPTS, and then restart Tomcat. Look at the file tomcat-install/bin/catalina.sh or catalina.bat for how this variable is used. For example,</p> <p>set CATALINA_OPTS=-Xms512m -Xmx512m (Windows, no "" around the value)<br> export CATALINA_OPTS="-Xms512m -Xmx512m" (ksh/bash, "" around the value)<br> setenv CATALINA_OPTS "-Xms512m -Xmx512m" (tcsh/csh, "" around the value)</p> </blockquote> <p>So I replaced the line </p> <blockquote> <p>set CATALINA_OPTS= </p> </blockquote> <p>with </p> <blockquote> <p>set CATALINA_OPTS=-Xms512m -Xmx512m </p> </blockquote> <p>But I still get the error.</p> <blockquote> <p>javax.servlet.ServletException: Servlet execution threw an exception</p> <p>root cause</p> <p>java.lang.OutOfMemoryError: Java heap space java.lang.reflect.Array.multiNewArray(Native Method) java.lang.reflect.Array.newInstance(Array.java:90) nom.tam.util.ArrayFuncs.newInstance(ArrayFuncs.java:1028) nom.tam.fits.ImageData.read(ImageData.java:259) nom.tam.fits.Fits.readHDU(Fits.java:573) controller.UploadServlet.retreiveFITSFileFields(UploadServlet.java:206) controller.ScanServerFiles.doPost(ScanServerFiles.java:39) javax.servlet.http.HttpServlet.service(HttpServlet.java:637) javax.servlet.http.HttpServlet.service(HttpServlet.java:717)</p> </blockquote>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
