一次配置oracle em的經歷

對oracle10grac配置em，原本是非常簡單的事，卻花費了很長時間，記錄下來，備忘。

首先是報如下錯誤：

[oracle@node1 admin]$ emca -config dbcontrol db

網上查資料，是oracle的bug。

Oracle對此的解釋是：

In Enterprise Manager Database Control with Oracle Database 10.2.0.4 and 10.2.0.5, the root certificate used to secure communications via the Secure Socket Layer (SSL) protocol will expire on 31-Dec-2010 00:00:00. The certificate expiration will cause errors if you attempt to configure Database Control on or after 31-Dec-2010. Existing Database Control configurations are not affected by this issue.

If you plan to configure Database Control with either of these Oracle Database releases, Oracle strongly recommends that you apply Patch 8350262 to your Oracle Home installations before you configure Database Control. Configuration of Database Control is typically done when you create or upgrade Oracle Database, or if you run Enterprise Manager Configuration Assistant (EMCA) in standalone mode.

可以查看：Enterprise Manager Database Control Configuration - Recovering From Errors Due to CA Expiry on Oracle Database 10.2.0.4 or 10.2.0.5 [Video] [ID 1222603.1]

解決方法：

如果是在創建實例前就已經打了這個patch的話，那之後就不會報錯了。如果是在創建實例之後纔打的這個patch，那麼需要執行以下：

對於單實例：
1.使用Opatch安裝Patch 8350262
2.設置ORACLE_HOME and ORACLE_SID 環境變量，執行 <PATCH_HOME>/killDBConsole.(windows 平臺省略這一步)
3.Re-secure Database Control with the following command:
<ORACLE_HOME>/bin/emctl secure dbconsole -reset
4.Re-start Database Control with the following command:
<ORACLE_HOME>/bin/emctl start dbconsole

對於RAC：
1.使用Opatch安裝Patch 8350262, 在一個節點安裝就ok了。
2.在所有節點執行：設置ORACLE_HOME and ORACLE_SID 環境變量，執行 <PATCH_HOME>/killDBConsole.(windows 平臺省略這一步)
3.Re-secure Database Control on the first cluster node with the following command:
<ORACLE_HOME>/bin/emctl secure dbconsole -reset
4.Re-secure Database Control on the remaining cluster nodes with the following command. Note that the -reset switch is not included with this command:
<ORACLE_HOME>/bin/emctl secure dbconsole
5.Re-start Database Control by executing the following command on each node in the cluster:
<ORACLE_HOME>/bin/emctl start dbconsole

打補丁後，清除並新建em，各種報錯，無奈下手工刪除各種數據：

之後新建em成功，
