折騰oracle的em1

最近安裝oracle，em總是不順利，決定好好搞搞它。

首先發現10。2.0.4開始使用https了，關鍵是一個證照在2011年過期，基本只要打了10.2.0.4的補丁的資料庫，em就會報錯。不用管它。都安裝完成後，在打一個補丁就可以了。這個補丁oracle提供了所有平臺的一個版本。安裝步驟參照網上現成的：

單機版步驟：

Recovering from Configuration Errors on a Single Instance Database
1. Ignore any errors and continue with the installation or upgrade. The database will be created without errors.

2. Apply Patch 8350262 to your Oracle Home installation using OPatch.

opatch apply

Verifying the update...
Inventory check OK: Patch ID 8350262 is registered in Oracle Home inventory with proper meta-data.
Files check OK: Files from Patch ID 8350262 are present in Oracle Home.

OPatch succeeded.

3. After applying the patch, 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.

To execute the killDBConsole script.:

Set the ORACLE_HOME and ORACLE_SID environment variables.
Execute /killDBConsole.
Note for Windows Platform. Only:

It is not necessary to force stop the dbconsole process on the Windows platform, because the process will
already be in a stopped state at the end of the failed configuration attempt.

The killDBConsole script. output is shown below:

$ /killDBConsole
ORACLE_HOME=/myhost/db_1
ORACLE_SID=caem31
State directory = /myhost/db_1/staxd10_caem31
WatchDog PID = 802932
DBconsole PID = 577716
EMAgent PID = 512156
Killing WatchDog (pid=802932) ...
Successfully killed process 802932
Killing DBConsole (pid=577716) ...
Successfully killed process 577716
Killing EMAgent (pid=512156) ...
Successfully killed process 512156

4. Re-secure Database Control with the following command:

You will be prompted twice to confirm that the Root key must be overwritten. In both cases, enter upper-case "Y" as the response. Any other response (including lower-case "y") will cause the command to terminate without completing. If this happens, the command can be re-invoked.

$ ./emctl secure dbconsole -reset
