如何生成 hprof文件 + weblogic启动文件配置

系统宕机了，weblogic生成 .phd 和  javacore文件，分别使用 jca457.jar  和  ha456.jar来分析，但是heapdump文件分析时指向的问题和内存泄漏点类并不是很方便对应我们的代码，所以想使用mat工具来分析，但是需要生成 hprof文件

需要修改startWebLogic.sh文件，宕机时就会自动生成对应的hprof文件

# This script is used to start WebLogic Server for this domain.

# 

# To create your own start script for your domain, you can initialize the

# environment by calling @USERDOMAINHOME/setDomainEnv.

# 

# setDomainEnv initializes or calls commEnv to initialize the following variables:

# 

# BEA_HOME       - The BEA home directory of your WebLogic installation.

# JAVA_HOME      - Location of the version of Java used to start WebLogic

#                  Server.

# JAVA_VENDOR    - Vendor of the JVM (i.e. BEA, HP, IBM, Sun, etc.)

# PATH           - JDK and WebLogic directories are added to system path.

# WEBLOGIC_CLASSPATH

#                - Classpath needed to start WebLogic Server.

# PATCH_CLASSPATH - Classpath used for patches

# PATCH_LIBPATH  - Library path used for patches

# PATCH_PATH     - Path used for patches

# WEBLOGIC_EXTENSION_DIRS - Extension dirs for WebLogic classpath patch

# JAVA_VM        - The java arg specifying the VM to run.  (i.e.

#                - server, -hotspot, etc.)

# USER_MEM_ARGS  - The variable to override the standard memory arguments

#                  passed to java.

# PRODUCTION_MODE - The variable that determines whether Weblogic Server is started in production mode.

# DERBY_HOME - Derby home directory.

# DERBY_CLASSPATH

#                - Classpath needed to start Derby.

# 

# Other variables used in this script include:

# SERVER_NAME    - Name of the weblogic server.

# JAVA_OPTIONS   - Java command-line options for running the server. (These

#                  will be tagged on to the end of the JAVA_VM and

#                  MEM_ARGS)

# CLASS_CACHE    - Enable class caching of system classpath.

# 

# For additional information, refer to "Managing Server Startup and Shutdown for Oracle WebLogic Server"

#  (http://download.oracle.com/docs/cd/E17904_01/web.1111/e13708/overview.htm).
