现象：当Weblogic Managed Server启动时，到达下列日志的最后一行时，要过很久（5分钟以上）才能继续显示下一行日志。

解决方法：

1. 修改Weblogic对应JAVA_HOME下的jre/lib/security/java.security文件

[plain]

1. securerandom.source=file:/dev/./urandom  

securerandom.source=file:/dev/./urandom

2. 修改Weblogic Server的启动的JAVA_OPTION参数

[plain]

1. -Djava.security.egd=file:/dev/./urandom  

-Djava.security.egd=file:/dev/./urandom

修改后，出现下一行日志的时间有分钟级别缩短到秒级别（我的环境是10秒内）。
