dbconsole can’t be started with ssl error

Filed under: [RAC] — Tags: , , , — zhefeng @ 2:36 pm

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.


  1. Thanks!
    I’ve had this problem, and your suggestions worked fine for me. Do you have an explanation on how this happened? The customer told me that the problem has started after a machine reboot due to Windows patch installation (Windows 2008), because before all was running smoothly.

  2. Hi and thanks for the tip ;-D

    After a new base creation I can’t secure the dbconsole, but after the “emctl upload” comand it work fine.
