使用wlst脚本的Weblogic应用程序部署会发出内存不足异常

Question

I am deploying an application using wlst script in Weblogic 12.1.2 and JDK 1.7.0.75. All the tasks(create domain, cofigure Admin Server, Start Server, connect) written in wlst script works, except for application deployment. App Deployment script:

deploy(appName='App1', path='D://Applications//App1', targets='AdminServer', stageMode='nostage', securityModel='DDOnly')

Through console the application is deployed without any memory issues. In console, I have chosen: Target style as "Install this deployment as an application", Security Model as "DD Only: Use only roles and policies that are defined in the deployment descriptors.", Staging Mode/Source Accessibility as "I will make the deployment accessible from the following location" and Plan Staging Mode/Plan Source Accessibility "Use the same accessibility as the application".

Do I have to set any specific memory settings in wlst script for it to deploy successfully? Out of Memory Exception:

org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from class path resource [beans-config.xml]; nested exception is java.lang.OutOfMemoryError: PermGen space

Answer 1

I don't know about wlst script. But when i happen to see such errors while working with WebLogic, I change the permgen values in the following file:

Oracle\\Middleware\\Oracle_Home\\user_projects\\domains\\mydomain\\bin\\setDomainEnv.cmd

(if you are working on UNIX system, see the setDomainEnv.sh file). Look for attributes

MEM_MAX_PERM_SIZE_64BIT=-XX:MaxPermSize=1024m
MEM_MAX_PERM_SIZE_32BIT=-XX:MaxPermSize=512m

Based on your Operating System (32 bit or 64 bit), set these values to higher digits. Restart your WebLogic instance.

Answer 2

通过如下所述指定内存参数，在启动服务器后成功部署了应用程序：startServer（'AdminServer'，'my_domain'，'t3：// localhost：7001'，'weblogic'，'password'，'user_projects / domain / my_domain'，'true'，60000，'false'， jvmArgs ='-XX：MaxPermSize = 256m，-Xms512m，-Xmx512m' ）

As you are deploying a app into domain level, best way is using Administration Console -> deployments -> install and then, change your deploy configure on the UI. Most situation, it will go through.

WSLT be used to deploy app to partition is good reference.

Java 8 have much better memory management. Update your JDK version to 8, this problem may go away.
