1 解決2011年及之後EM無法啓動問題
最近在搭一個linux虛擬機環境學習oracle，在進行手工建庫後創建EM時報錯了，EM無法啓動。在今年的一個項目的RAC環境中好像也是EM無法啓動，但實際可以登錄進行訪問，但一直沒想到是什麼原因。記得去年也是用同樣的方法創建的數據庫，EM好像就可以正常使用。於是上網查了一下，發現居然是oracle的一個BUG，遇到了OEM bug 8350262，需要打補丁進行解決。
原因爲The Root Certificate Authority (CA) expired on 31-DEC-2010 00:00:0 root授權信息過期導致。

解決該問題步驟
如果是在創建實例之前就把該patch給打上了，那麼在創建OEM的時候不會受影響。
如果是已經報錯了，解決步驟如下：
For Single Instance：
1. 使用Opatch 安裝Patch 8350262
2. force stop the Database Control (dbconsole) process using the killDBConsole script bundled with the patch. Note that the dbconsole process cannot be stopped using the emctl stop dbconsole command, as EMCTL is unable to connect to the process.
（1）Set the ORACLE_HOME and ORACLE_SID environment variables.
（2）Execute <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
For RAC Instance：
1. 使用Opatch 安裝Patch 8350262, 在一個節點安裝就ok了。
2. force stop the Database Control (dbconsole) process by executing the killDBConsole script bundled with the patch on each node in the cluster
在所有節點執行
（1）Set the ORACLE_HOME and ORACLE_SID environment variables.
（2）Execute <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

1.2 停止DBCONSOLE
按照步驟做下去沒有成功，不知道什麼原因，沒仔細去研究，想到了重建EM，結果重建EM成功了。
以前有碰到過用emctl stop dbconsole無法停止EM的情況，剛好上面的補丁中帶了一個殺EM進程的程序，所以直接使用
