IBM WAS 8.5错误重新启动

Question

We have an application which was deployed on WAS 7.5 and it would run into the issue out of heap memory exception it would automatically restart. After migrating it to WAS 8.5 with the same error it won't restart. Is this a known issue with WAS 8.5 or there is some configuration option to be set for WAS 8.5?

The application is built using java/JSP. We are working on fixing memory leaks on the application. We also need to solve the above configuration problem.

Let me know if some more information is required, will edit the question posted.

Answer 1

I know this as a function on the jdk. There is a parameter on the java runtime to run a script in case of an OOM situation. See http://docs.oracle.com/javase/8/docs/technotes/tools/windows/java.html#BABCBGHF

-XX:OnOutOfMemoryError :

-XX:OnOutOfMemoryError=string

Sets a custom command or a series of semicolon-separated commands to run when an OutOfMemoryError exception is first thrown. If the string contains spaces, then it must be enclosed in quotation marks. For an example of a command string, see the description of the -XX:OnError option.

-XX:OnError=string

Sets a custom command or a series of semicolon-separated commands to run when an irrecoverable error occurs. If the string contains spaces, then it must be enclosed in quotation marks.

The following example shows how the -XX:OnError option can be used to run the userdump.exe utility to obtain a crash dump in case of an irrecoverable error (the %p designates the current process):

-XX:OnError="userdump.exe %p"

The preceding example assumes that the path to the userdump.exe utility is specified in the PATH environment variable.
