After searching the metalink, found just need to unsecure and resecure the dbconsole to renew the expired dbconsole certificate:

1. Unsecure the Dbconsole
– Unsecure database control using
$ORACLE_HOME/bin>emctl unsecure dbconsole

2. Force an upload:

$ORACLE_HOME/bin> emctl upload

3. Also consider Resecuring the Dbconsole
– Secure database control using
$ORACLE_HOME/bin>emctl secure dbconsole

Starting with 10.2.0.4, HTTPS is used by default.

chm can’t be opened

My desktop somehow couldn’t open the chm file which was ok before.
After researching i found it’s the microsoft updates caused this:
http://support.microsoft.com/kb/896358

The solution will be open permissions for this kind of chm file. Copy/paste the following code to a text file then save it as .reg, run it and resolve the problem!
