Refer to Oracle Metlink Doc [1222603.1]
we need to do the following :
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
To apply the patch :
A-change to Patch directory .
B-export ORACLE_SID = ORCL
C-export ORACLE_HOME= /u01/oracle/product/10.2.0/db_1/
D-$ORACLE_HOME/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-If you using linux you need to kill all dbconsole process by “KillDbconsole” you will find it in the same patch directory
, if you are using windows no need to kill anything .
$ /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 DBConsole (pid=577716) ...
Successfully killed process 577716
Killing EMAgent (pid=512156) ...

4-This not optional steps you need to do it :
./emctl secure dbconsole -reset
