Question

我有一个在AWS上运行的weblogic服务器。我对其进行了AMI备份，并从AMI创建了新实例。

在新实例中，当我尝试启动weblogic时，它停留在以下状态。

<Dec 11, 2018 12:00:01 AM IST> <Info> <Management> <BEA-141107> <Version: WebLogic Server 10.3.6.0  Tue Nov 15 08:52:36 PST 2011 1441050 > 
<Dec 11, 2018 12:00:02 AM IST> <Notice> <WebLogicServer> <BEA-000365> 
<Server state changed to STARTING> 
<Dec 11, 2018 12:00:02 AM IST> <Info> <WorkManager> <BEA-002900> <Initializing self-tuning thread pool> 
<Dec 11, 2018 12:00:02 AM IST> <Notice> <Log Management> <BEA-170019> <The server log file /home/weblogic/Oracle/Middleware/user_projects/domains/ClassicDomain/servers/AdminServer/logs/AdminServer.log is opened. All server side log events will be written to this file.

任何帮助将不胜感激。

问题已解决。

在线程转储中，我发现了

 "[ACTIVE] ExecuteThread: '0' for queue: 'weblogic.kernel.Default (self-tuning)'" daemon prio=10 tid=0x00007fda6aad4800 nid=0x6a3b runnable [0x00007fda41d5d000]

在Google中进行了一些搜索，并找到了更改$ JAVA_HOME / jre / lib / security / java.security中以下行的解决方案

来自

securerandom.source=file:/dev/urandom

收件人

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

然后重新启动weblogic解决了该问题。
