对oracle10grac构造em，原本很easy事儿，但它需要一个很长的时间，记录下来。MEMO。
首先，例如，报告了以下错误：

网上查资料，是oracle的bug。
Oracle对此的解释是：
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.
能够查看：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]
解决方法：
假设是在创建实例前就已经打了这个patch的话，那之后就不会报错了。
假设是在创建实例之后才打的这个patch。那么须要运行下面：
对于单实例：
1.使用Opatch安装Patch 8350262
2.设置ORACLE_HOME and ORACLE_SID 环境变量。运行 <PATCH_HOME>/killDBConsole.(windows 平台省略这一步)
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
对于RAC：
1.使用Opatch安装Patch 8350262, 在一个节点安装就ok了。
2.在全部节点运行：设置ORACLE_HOME and ORACLE_SID 环境变量。运行 <PATCH_HOME>/killDBConsole.(windows 平台省略这一步)
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
打补丁后。清除并新建em，各种报错，无奈下手工删除各种数据：

之后新建em成功。
