EM dbconsole will not start

User_N1VOLApr 7 2014 — edited Apr 11 2014

Hello all,

I have a problem starting the dbconsole on the following system:

OS: Oracle Linux 5.5 x86_64 ,  iptables and SELinux are disabled.

DB: Oracle Database 10.2.0.5

Symptoms:

- The Enterprise Manager console stopped working (see errors below)

- The ' emctl status dbconsole' showed that it was not running

- When I tried to start the dbconsole with 'emctl start dbconsole' it said that the instance was running so I tried to stop it first - 'emctl stop dbconsole' - did not work (hung), I killed it with kill -9 <emctl.pid>

- I tried to start it with 'emctl start dbconsole' which did not work (it didn't stop, but it kept producing the same errors below)

emdctl.trc output:

2014-04-07 18:43:32 Thread-4134751008 ERROR http: 7: Unable to initialize ssl connection with server, aborting connection attempt

Then when I tried to start the dbconsole I got:

Then the last two lines keep repeating until I stop the starting process by ctrl-c


This is the output from emagent.trc:

However the command: emctl status agent returns that the Agent is Running and Ready

emagent.log reports everything is successful.

I found that it could be a problem with the sertificate so I unsecured and secured the dbconsole 'emctl unsecure dbconsole'  and 'emctl secure dbconsole'.

It went fine. secure.log reported everything was successful, however the symptoms from starting the dbconsole remained the same.

Nothing has been changed on the system (or so I was told). I noticed that the 1158 port was commented out in /etc/services file, so I uncommented it and tried the procedure again, but that didn't change anything.

I also tried telneting to the system from another machine, to the port 1158 and 1830 (agent port) and it worked fine so it's not a firewall issue.

Does anyone have any idea what could be the problem ? I have seen that many people had similar problems but so far nothing I found on forums worked (or I missed it)

Best regards,

Blaz
