   escheduler-daemon.sh脚本内统一的进程启动设置：
   
   ```shell
   export ESCHEDULER_OPTS="-server -Xmx4g -Xms2g -Xss512k -XX:+DisableExplicitGC -XX:+UseConcMarkSweepGC -XX:+CMSParallelRemarkEnabled -XX:LargePageSizeInBytes=128m -XX:+UseFastAccessorMet
   hods -XX:+UseCMSInitiatingOccupancyOnly -XX:CMSInitiatingOccupancyFraction=70"
   ```
