JON - Security Token 不見怎麼辦!

這個算是FAQ了,安裝JON 的時候,有些東西要特別注意,以免日後要修改很困難,
如你的Agent 的名字,因為JON 會把兩邊的資料存在Agent 與 Server身上,
所以,如果你突然想換那麻煩就大條了。

出問題的地方,有些人重新安裝了Agent之後,出現了無法與Server聯結的問題。
如果,去看一下你的console上與Log中會看到類似以下的error,

The agent will now wait until it has registered with the server..


Cause: [org.rhq.core.clientapi.server.core.AgentRegistrationException:An agent is trying to register with an existing agent name [xxxx] without providing a valid security token. If you are attempting to re-register this agent, please consult an administrator to obtain the agent's proper security token and restart the agent with the option "-Drhq.agent.security-token=<the valid security token>"

這就是因為agent 身上的security token, 已經在重裝的時候被清掉了。
所以只要把token重新裝上去就好。如何安裝咧~

1. 先把Agent停下來。
2. 登入JON 的 server, 請記得這個登入的賬號要有安全設定的security 權限。
3. 按下最上方的Administrator, 左邊選單選擇Agent,找到你要重新安裝security token的agent名字。


4. 接下來的頁面就會有這個agent的資訊,請複製上面的security token.


5. 重新啓動你的agent, 執行的時候,加上  
-Drhq.agent.security-token=剛剛複製的securityToken


security token 就會重新安裝好了,以上。

Fuse and A-MQ 6.3 GA has just went out. Maybe, you would think this is just only a minor version release why should I care? Hold your thoughts on that! Because they have done a lot of improvements and also added many new features into this release.

Besides various bug fixes and making sure Fuse Fabric is much more stable. There are two major change in this version update:

New Tooling in JBoss Developer Studio (JBDS) 9.1 GA. Newer Apache Camel version – Camel v2.17. I was really impressed by the work put in to make developing Camel application much simpler. First is the installation of tooling itself. Now it has a all-in-one installer so you don't need to worry about which plugins you need to check. See the videos below to see the new "Getting Started" of Fuse 6.3.
