如何生成 hprof文件 + weblogic启动文件配置
来源：互联网 发布：新版淘宝购物评级在哪 编辑：程序博客网 时间：2024/04/30 10:38
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
LOG_OPTIONS="-Xloggc:$LOG_PATH/gc.$$.log -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:HeapDumpPath=$LOG_PATH/heapdump.$$.hprof -XX:ErrorFile=$LOG_PATH/hs_err_pid.$$.log"

# PATCH_CLASSPATH - Classpath used for patches
# PATCH_LIBPATH - Library 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.
