How To Resolve Out Of Memory Error In Weblogic
4 down vote favorite 1 How do I increase the memory used by my Weblogic (Java). While starting the server from eclipse it shows a message that JAVA Memory arguments: -Xms256m -Xmx512m -XX:MaxPermSize=256m. I couldn't understand from where is it taking that value from. After sometime the Weblogic server fails because of low permgen space. I added startup arguments from console but that doesn't have weblogic maxpermsize any effect. Can you help me from where is it taking the memory values from? java weblogic permgen weblogic12c share|improve this question asked Nov 8 '13 at 10:50 Akhil K Nambiar 1,44283065 add a comment| 5 Answers 5 active oldest votes up vote 5 down vote accepted When you configure a "Server" in Eclipse for WebLogic, you select a domain directory (for local). That domain directory contains the startup scripts that Eclipse will use to start the WebLogic Server. These are the same scripts that you would use if you started the server if you did it without Eclipse. Inside the domain directory is a folder called "bin". In the "bin" directory, locate the setDomainEnv file (.sh for unix, or .cmd for Windows). In that file, alter the memory settings to suite your needs. Based on the error message you mentioned in your question, I would increase both the PermSize and MaxPermSize settings to 512m. For PermSize and MaxPermSize, there are two locations each by default in a simple WLS installation, one for 32-bit, and another for 64-bit. It won't hurt to change them both. But if you know which JVM architecture you are runni

Possible causes: - not enough swap space left, or - kernel parameter MAXDSIZ is very small. Solution: Although it appears that an out of memory OutOfMemoryError is thrown this apparent exception is reported by the HotSpot VM code when an allocation from the native heap failed and the native heap may be close to exhaustion. The message indicates the size (in bytes) of the request that failed and also indicates what the memory is required for. In some cases the reason will be shown but in most cases the reason will be the name of a source module reporting the allocation failure. If an OutOfMemoryError with this error is thrown it may require using utilities on the operating system to diagnose the issue further. Examples of issues that may not be related to the application are when the operating system is configured with insufficient swap space, or when there is another process on the system that is consuming all memory resources.

Why talk about Fusion or Weblogic admins this issue can be encountered on multiple products like the Oracle Applications EBS, Hyperion, OTM, Oracle Application server and many other products .What seems common across all these products is the use of Application server. All the above mentioned products use some or the other application server over which the applications are deployed. For example the latest Oracle SOA Suite 11g uses Weblogic 10.3 Application Server while EBS Release 12 uses Oracle Application Server 10g. The point I am trying to make is the Out of Memory issue is not product specific but is related to Application Servers running Oracle-Sun JVMs. Application servers like Oracle Weblogic, IBM Websphere and Oracle Application Server facilitate running Java Virtual Machines on which the Java Applications can be deployed and executed. Out of memory issue is related to filled up space issues in these JVMs which makes it generic across all the above mentioned application servers. Before understanding OOM let's first understand the memory used by the JVM. The Java Virtual Machine (JVM) has the following types of memory: Heap memory is the runtime data area from which memory for all class instances and arrays is allocated Non-heap memory includes the method area and memory required for the internal processing or optimization of the JVM. It stores per-class structures such as a runtime constant pool, field and method data, and the code for methods and constructors. Native memory is the virtual memory managed by the operating system. When the above mentioned memory is insufficient for a deployed application, ajava.lang.OutOfMemoryError is thrown. There will be different error messages for OutOfMemoryErrors in each type of memory. They are listed below: - Heap memory error. When an application creates a new object but the heap does not have sufficient space and cannot be expanded further, an OutOfMemoryError will be thrown with the following error message: jav
