EM 12c Cloud Control - Agent Unreachable : Received Key Mismatch from OMS - 1
環境為 EM Cloud Control 12c,測試MWaaS 。 同事在做完MWaaS中的profile建立, 發現Middleware的主機(target)
在OMS上顯示的Agent狀態是 unreachable , 檢視狀態發現 OMS 正常,其他幾個target在OMS Console上顯示也是正常
的, 沒有出現 Agent Unreachable 的提示, 而且正常和不正常的幾個target 都是在同一個網段,基本可以排除網路
問題,OMS Server問題也可以排除。
1. 檢查狀態為 Agent Unreachable 的主機上的Agent狀態
檢查agent程式正常
cd /u01/em12c/agent/agent_inst (即cd $AGENT_HOME)
$ ./emctl status agent
顯示Heartbeat Status : OMS is unreachabled
嘗試重新啟動Agent
$ ./emctl stop agent
$ ./emctl start agent
$ ./emctl status agent
顯示狀態還是有問題。
2. 透過 pingOMS 檢查Agent與OMS的通訊問題
cd /u01/em12c/agent/agent_inst (即cd $AGENT_HOME)
$ ./emctl pingOMS
EMD pingOMS error: Received Key Mismatch from OMS
根據錯誤在Metalink上查詢原因。透過Agent Unreachable 及 Received Key Mismatch from OMS 查詢到解決方案:
"oracle.sysman.emSDK.agent.comm.exception.KeyMismatchException: agent key mismatch" error for 12c agent (文件 ID 1569471.1)
Cause
The issue is due to secure key mismatch between agent and OMS.
Solution
Issue the following commands for problematic agent from AGENT_HOME/bin:
emctl stop agent
emctl secure agent
emctl start agent
Now wait for 5 minutes and check the status of agent : emctl status agent
但是在執行後,等待 5 分鐘,還是不行,顯示是 Agent Unreachable 。
在OMS上顯示的Agent狀態是 unreachable , 檢視狀態發現 OMS 正常,其他幾個target在OMS Console上顯示也是正常
的, 沒有出現 Agent Unreachable 的提示, 而且正常和不正常的幾個target 都是在同一個網段,基本可以排除網路
