Unable to start DB Control oracle 10.2.0.4 & 10.2.0.5


After 31-Dec-2010, all 10.2.0.4 and 10.2.0.5 dbconsoles will face problems during secure/unsecure operations and during dbconsole configuration.


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.


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.


How to apply the patch?
Download the patch 8350262, unzip to /u01/patch/10204/8350262

Apply the patch,

[oracle@emvml 8350262]$  $ORACLE_SID/OPatch/opatch apply
Invoking OPatch 10.2.0.4.9

Oracle Interim Patch Onstaller version 10.2.0.4.9
Copying (c) 2009, Oracle Corparation.  All rights reserved.

.

At the end you should get a message OPatch succeeded.

After applying the patch, there might me some DB Console related process might not get killed. In order to kill those process.
Go to the patch directory and execute killDBConsole,


After killing the process, resecure the SSL by issuing the below command,




[oracle@emvml 8350262]$  $ORACLE_SID/bin/emctl secure dbconsole -reset 


Enter the following details,


Step 1 : Enter enterprise manager root password :SYSMAN PASSWORD
Step 2 : Y
Step 3 : Y


Note : If it is a RAC database,first node use -reset, on the second node resecure the SSL by the giving the above command without giving -reset


Example : $ORACLE_SID/bin/emctl secure dbconsole


Once the resecure command sucessful,


Start the DB Console,




Start the EM,
Hope this document help !!!

  1. However, you cannot deploy goblins without the assistance of other troops such as barbs or giants because they will get crushed easily.

    Many more games, on many more platforms, expectantly over time puts up those streams in to a
    proper violent flow of income. Signs and symptoms involve long hours of play, compulsive thoughts about the game, and too much spending relevant to online
    games of all sorts.
