a WebSphere Application Server, the deployment fails. The deployment failure websphere outofmemoryerror usually occurs with WebSphere Application Server 7, but can also occur with other WebSphere Application Server

versions. Symptom The deployment fails and an error message is displayed. For example: WASX7017E: Exception received while running file "/opt/IBM/ECMClient/configure/tmp/deployapplication.tcl"; exception information: com.ibm.websphere.management.application.client.AppDeploymentException: com.ibm.websphere.management.application.client.AppDeploymentException: [Root exception is java.lang.outofmemoryerror java heap space ibm websphere java.lang.OutOfMemoryError] java.lang.OutOfMemoryError: java.lang.OutOfMemoryError Cause The default minimum and maximum heap sizes in the wsadmin file are too small. Environment WebSphere Application Server and WebSphere Application Server Network Deployment Diagnosing the problem The IBM Content Navigator EAR file deployment fails on WebSphere Application Server with an "Out of Memory" error message. Resolving the problem To how to resolve out of memory error in websphere resolve the problem, you must edit the wsadmin.sh or wsadmin.bat file: Set the Java virtual machine (JVM) initial heap size to 512 MB. Set the Java virtual machine (JVM) maximum heap size to 1024 MB.

Tags Solve the easy OutOfMemory problems with a javacore ScottyThomason 120000D4GC | | Comments (12) | Visits (47878) Tweet I talked with a https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/solve_the_easy_outofmemory_problems_with_a_javacore WebSphere Application Server support analyst the other day and they mentioned they had seen some "easy problems" coming in to Level 2 support recently. I thought it would be good to blog about these easy ones so you can solve on your own without consuming your time contacting support and sending documentation.Looking at documentation, such as a javacore, can sound like a daunting task if you do not know what to look for. But a javacore is just a readable text file with snapshot information of a running JVM. It contains operating system and Javatm info, who/why it was taken etc.The location of Javacores can be determined by looking for the message in the native_stderr.log. Here are a couple examples:JDK 5: JVMDUMP010I Java Dump written to /usr/WebSJDK 1.4: JVMDG304: Java core file written to /usr/WebS mode jython, jacl script, Trouble shooting, JDBC configuration, deployment tutorial, etc..

Also memory leak is a common memory problem that also leads out of to OutOfMemory error. In Java , memory leaks can not happen as it has automatic Garbage Collection (GC). GC removes unused objectsthat are not referenced anymore. But if an object is not used, but is still referenced, GC does not remove it, which leads to memory leaks in JVM . Due to the above memory leak or large out of memory objects error , the performance of the application server may decline or WAS may be crashed with OutOfMemory error. . Please check the error message java.lang.OutOfMemoryError" in the WAS log file ( i.e. native_stderr.log) One of Solution to the above error : When I increase the JVM Heap Size , the problem got solved . Now let us see , how to increase JVM Heap Size in Websphere Application Server You can solve the problem in two ways i) Using the IBM console ii) By changing the server.index file directly i). To tune the JVM Max Heap sizeusing the IBM console 1. Open the WebSphere Application Server administrative console, http://hostname:port/ibm/console, and log in. 2. Expand Servers -> Application servers -> server1 -> Java and Process Management -> Process Definition -> Java Virtual Machine. 3. Change the Max Heap Size to a larger value. 4. Click Apply and click Save . Restart WebSphere Application Server. ii).By changing the server.xml file directly Open theserver.xmlfile located in the followi here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Stack Overflow Questions Jobs Documentation Tags Users Badges Ask Question x Dismiss Join the Stack Overflow Community Stack Overflow is a community of 4.7 million programmers, just like you, helping each other.

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 ? 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 thanks it worked for me :-) –n
