Oracle EM Grid Control 11g問題之EMD upload失敗

在OEM grid control 11g 安裝完成后，在一個監控服務器上重裝agent 一下，agent 就不能工作了，使用emctl upload檢查時報錯為”EMD upload error: uploadXMLFiles skipped” 。如下所示：

[Oracle@codb2 ~]$ emctl upload

Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0
 

Copyright (c) 1996, 2010 Oracle Corporation.   All rights reserved.

---------------------------------------------------------------

EMD upload error: uploadXMLFiles skipped :: OMS version not checked yet. If this issue persists check trace files for ping to OMS related errors.

這是Oracle EM Grid Control 11g安裝指導 一文中介紹的安裝EM GRID CONTROL 11G結束后，配置agent時出現的問題。如果你需要知道如何去安裝配置grid control 11g，請參考此文http://www.linuxidc.com/Linux/2012-06/61632.htm。

這個問題如何解決呢？

首先，我在監控服務器上，也就是codb2 服務器上使用emctl verifykey 校驗一下。發現是OMS 將這個agent 給block 了。

[Oracle@codb2 ~]$ emctl verifykey

Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0

Copyright (c) 1996, 2010 Oracle Corporation.   All rights reserved.

-----------------------------------------------------

verifykey: Successfully Completed communication with agent

EMD pingOMS error: Invalid ping response "ERROR-Agent is blocked. Blocked reason is: Agent is out-of-sync with repository. This most likely means that the agent was reinstalled or recovered. Please contact an EM administrator to unblock the agent by performing an agent resync from the console. Please contact EM adminstrator to unblock the agent"

那么，我就去OEM grid control 11g 的控制臺上去解決這個block 。

在控制臺主目錄中，選擇未知的對象，代理重新同步，不成功。報錯如下：

“代理操作已完成,  但出現錯誤。對于那些無法保存的目標,  請轉至目標的監視配置頁以保存它們。已成功保存所有其他目標。仍未取消阻止代理。

與代理通信時出錯。異常錯誤消息  - Oracle.sysman.emSDK.emd.comm.CommException: IOException in reading Response :: Connection reset “

在界面操作上沒辦法去取消這個代理了。于是乎，我們登錄grid control 的資料庫中，去直接修改配置信息。

使用函數mgmt_admin.cleanup_agent('host:port');  去清理這個agent 。

參數host 和port 的值從監控端服務器中使用emctl status agent 輸出信息中取得。

詳細信息如下：

[Oracle@codb1 ~]$ emctl status agent

Agent is Running and Ready

請注意這一行

Agent URL          :https://codb1.htsc.com.cn:3872/emd/main

codb1.htsc.com.cn:3872 就是這些參數的值。在sqlplus 中以sysman 用戶登錄資料庫，執行

execute mgmt_admin.cleanup_agent('codb1.htsc.com.cn:3872');

執行過程如下：

/u01/Oracle/home@webdg2=>emrep$sqlplus sysman/htzq2012

SQL*Plus: Release 10.2.0.4.0 - Production on Thu May 31 17:15:54 2012

With the Partitioning, Real Application Clusters, OLAP, Data Mining

and Real Application Testing options

SQL> execute mgmt_admin.cleanup_agent('codb1.htsc.com.cn:3872');

PL/SQL procedure successfully completed.

接著，我們到監控端服務器上去清理一些文件

進入grid control 的安裝目錄，執行下列命令。

rm -r ./sysman/emd/state/*

rm -r ./sysman/emd/collection/*

rm -r ./sysman/emd/upload/*

rm ./sysman/emd/lastupld.xml

rm ./sysman/emd/agntstmp.txt

rm ./sysman/emd/blackouts.xml

rm ./sysman/emd/protocol.ini

最后重新配置一下agent

emctl clearstate agent

emctl secure agent

emctl start agent

這一切都執行完成后，檢查emctl upload 是不是正常了。

[Oracle@codb1 ~]$ emctl upload

Oracle Enterprise Manager 11g Release 1 Grid Control 11.1.0.1.0

EMD upload completed successfully

執行結果顯示已OK 。
