我无法在Eclipse中启动Weblogic服务器-服务器观察程序报告了未知状态

Question

When I start Eclipse(Mars), I see the weblogic server with both start and stop buttons active. The server modificator is empty - no [starting], [stopped], [running] or something else. And I cannot start nor stop it. At least, half an hour is not enough for it (timeouts are already set to large numbers). The situation does not change after:

• restarting Eclipse
• killing Eclipse and java processes in the task manager
• restarting the computer
• deleting the server in Eclipse and connecting to it back.
• -clean at eclipse start
• Erasing and reinstalling the Eclipse

The console output is empty.

Logs in Oracle_home are empty - no changes for the last 3 hours.

Four hours ago server ran and stopped OK. Then began to do it more and more slowly and it came to this.

Of course, I understand, that total delete of weblogic server installations with all domains or c:format could help, but is there some less drastic measure?

In the command line the server can be started by the same start script without any problems. So, the problem is obviously in Eclipse. Can I clean it somehow?

Eclipse log gives very interesting line at the try to start the server:

The server watcher reported an unknown state

The whole description of the problem is:

The server watcher reported an unknown state.

An exception stack trace is not available

And I am afraid, this message seems to be absolutely unknown - the line 'The server watcher reported an unknown state' has no hits in Google. What is strange for me, still no messages in WL logs - this message happens before any WL log starts.

Answer 1

The server watcher reported an unknown state

message

According to Configuring and Managing WebLogic Server

Automated pushing
Use SSL port
Start in debug mode

The only parameters for WL connecting to Eclipse except its folder are:

 Automated pushing Use SSL port Start in debug mode 

After some attempts I have found, that that problem was caused by checking

Use SSL port

After the delete of the server connection and reinstalling it without SSL, buttons stop , run and [stopped/started/starting] state returned to the normal functioning.
