Got problem like failing to start dbconsole, check the trace file got this:
2008-09-15 10:58:20 Thread-4136126688 ERROR http: 8: Unable to initialize ssl connection with
server, aborting connection attempt
2008-09-15 10:59:52 Thread-4136126688 ERROR ssl: nzos_Handshake failed, ret=29024.

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, HTTPS is used by default.

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

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!
