The logs report Java Heap Space and Out of Memory errors. I have searched online and the suggestions are to increase the JVM heap size. But how should I accomplish that now, when even the admin console is not working for me ? http://stackoverflow.com/questions/18377280/java-heap-space-out-of-memory-wtih-websphere-admin-console Is there a method to free up the heap space somehow ? java websphere share|improve this question asked Aug 22 '13 at 9:59 n.nasa 81119 add a comment| 3 Answers 3 active oldest votes up vote 18 down vote accepted In this situation you must bypass the administration console. If you want to do that just edit the configuration file for the server, i.e. edit the server.xml for that particular server, either the application server process or the deployment manager process depending on what process suffers from the memory problem. edit the following attributes: jvmEntries debugArgs="-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=7777" debugMode="false" disableJIT="false" genericJvmArguments="-Xquickstart" runHProf="false" verboseModeClass="false" initialHeapSize="512" maximumHeapSize="1024" verboseModeGarbageCollection="false" verboseModeJNI="false" xmi:id="JavaVirtualMachine_1183121908656" The server.xml can be found here: /*IBM_ROOT_DIR*/WebSphere/WAS85/AppServer/profiles/MyProfile/config/cells/MyCell/nodes/MyNode/servers/MyServer/server.xml After the update of the server.xml just restart the server process to utilize the new memory settings. share|improve this answer edited Aug 22 '13 at 11:00 answered Aug 22 '13 at 10:25 Robert Höglund 744812 2 I'd only go this route (hacking the XML) if restarting the JVM does not get you back into the Admin console. From there memory settings can be adjusted via the GUI. XML hacking should be a last resort. :-) –Nizzo Aug 22 '13 at 12:41 thank
in Atlassian Cloud apps, the contents of this article cannot be applied to Atlassian Cloud applications. Purpose Java applications like JIRA, Crowd https://confluence.atlassian.com/confkb/how-to-fix-out-of-memory-errors-by-increasing-available-memory-154071.html and Confluence run in a "Java virtual machine" (JVM), instead of directly within an operating system. When started, the Java virtual machine is allocated a certain amount of memory, which it makes available to applications like Confluence. By default, Java virtual machines are allocated 64Mb of memory, no matter how many gigabytes of memory your server may out of actually have available. 64Mb is inadequate for most Confluence installations, and so this needs to be increased. Diagnosis Expand to see diagnosis section Determine type of error message Look in the atlassian-confluence.log to see which type of OutOfMemory Error you're receiving. There are three common messages: Heap Space Perm Gen Space GC Overhead This document discusses out of memory increasing memory to address PermGen and Heap space errors. Follow the links above to assess root causes for each issue. For GC Overhead, refer to Confluence Crashes Due to 'java.lang.OutOfMemoryError GC overhead limit exceeded'. Determine Confluence's usage patterns In Confluence, go to Confluence Administration > System Information , and look at the memory graph during times of peak usage: This server has been allocated a maximum of 650Mb and a minimum of 256m. You can see the minimum displayed here; if you're trying to see whether your settings are being picked up, this is where to look. Determine available system memory On Windows From the Close Programs Dialogue (Press ctrl-alt-delete), select the Performance tab: The amount marked Available is the amount in kilobytes you have free to allocate to Confluence. On this server we should allocate at most 214Mb. On Linux Run cat /proc/meminfo to view the memory usage. Setting the -Xmx above the available amount on the server runs the risk of OutOfMemoryErrors due to lack of physical memory
