WebLogic MEM_ARGS 參數設定

          我發現在啟動我的一個JAVA應用中，盡管我在Linux環境給webgic的startWebLogic.sh設定了一 MEM_ARGS="-Xms1024m -Xmx1024m  -XX:PermSize=128m -XX:MaxPermSize=512m"參數但是不起作用，附件是配置檔案startWebLogic.sh,經過好長時間的檢查終于找出問題所在。

          附件中黑體字所在參數的設定在“. ${WL_HOME}/common/bin/commEnv.sh”條語句之前，從這條語句的注釋看大緻意思是：“如果java_vendor 設定的話，系統會執行該語句，使用cat 指令看了commEnv.sh檔案後才知道系統預設的參數是MEM_ARGS=="-Xms32m -Xmx200m  --XX:MaxPermSize=128m"，是以我想把設定參數這條語句MEM_ARGS="-Xms1024m -Xmx1024m  -XX:PermSize=128m -XX:MaxPermSize=512m"放到“. ${WL_HOME}/common/bin/commEnv.sh之後應該就起作用了吧。經過測試确實如此

# This script is used to start WebLogic Server for the domain in the

# current working directory.  This script simply sets the SERVER_NAME

# variable and starts server.

#

# To create your own start script for your domain, all you need to set is

# SERVER_NAME, then starts the server.

# Other variables that startWLS takes are:

# WLS_USER     - cleartext user for server startup

# WLS_PW       - cleartext password for server startup

# PRODUCTION_MODE    - true for production mode servers, false for

#                development mode

# 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)

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

#                -hotspot, etc.)

# MEM_ARGS     - The variable to override the standard memory arguments

#                passed to java
