glassfish中的Java Heap Space错误

Question

我正在使用一个新的Glassfish安装,只需很少的自定义.

我有一个消息驱动Bean(ObjectUpdateMDB),它监听一个主题,然后更新它在数据库中收到的对象.有很多对象正在更新.经过一段时间的运行后,我得到了这个例外:

SEVERE: JTS5031: Exception [org.omg.CORBA.INTERNAL:   vmcid: 0x0  minor code: 0 completed: Maybe] on Resource [rollback] operation.
SEVERE: MDB00049: Message-driven bean [Persistence:ObjectUpdateMDB]: Exception in postinvoke : [javax.transaction.SystemException: org.omg.CORBA.INTERNAL: JTS5031: Exception [org.omg.CORBA.INTERNAL:   vmcid: 0x0  minor code: 0 completed: Maybe] on Resource [rollback] operation.  vmcid: 0x0  minor code: 0  completed: No]

看起来这是堆空间的问题.我需要什么来调整堆空间？App Server本身还是经纪人？我该怎么做呢？

Answer 1

您需要为Glassfish安装分配更多RAM.

请参见http://spaquet.blogspot.com/2006/07/liferay-glassfish-part-ii-configuring.html

和http://docs.sun.com/app/docs/doc/820-4495/gepzd?a=view.

Answer 2

我使用以下asadmin命令对Glassfish 3.1上的问题进行排序:

asadmin create-jvm-options --target server-config -- '-XX\:+UnlockExperimentalVMOptions'
asadmin create-jvm-options --target server-config -- '-XX\:+UseG1GC'
asadmin delete-jvm-options --target server-config -- '-Xmx512m'
asadmin create-jvm-options --target server-config -- '-Xmx1024m'
asadmin delete-jvm-options --target server-config -- '-XX\:MaxPermSize=192m'
asadmin create-jvm-options --target server-config -- '-XX\:MaxPermSize=256m'

asadmin create-jvm-options --target default-config -- '-XX\:+UnlockExperimentalVMOptions'
asadmin create-jvm-options --target default-config -- '-XX\:+UseG1GC'
asadmin delete-jvm-options --target default-config -- '-Xmx512m'
asadmin create-jvm-options --target default-config -- '-Xmx1024m'
asadmin delete-jvm-options --target default-config -- '-XX\:MaxPermSize=192m'
asadmin create-jvm-options --target default-config -- '-XX\:MaxPermSize=256m'

这是迈克尔迈尔斯提示的一个变种.使用asadmin命令可以轻松地重复更改.

此外,我切换到新的G1收集器,这比普通收集器好很多.也帮助Eclipse ;-)

请注意,语法适用于Windows上的TakeCommand.如果你使用shell和OS的不同组合,你可能需要不同的转义字符(iE strait ticks而不是大多数unix shell的反引号).

如果您使用*-jvm-options命令弄乱了设置,那么您可以使用domain.xml文件修复它.
