Error running Enterprise Manager Configuration Assistant

Question

Dear all, another problem.
I've installed a Oracle Enterprise Linux 5 in a machine with Oracle Database 10g R2. After the installation process I started to create a Oracle Database because I hadn't done this with the Oracle Server installation process. So, everything was going fine till almost the end of the creation, when I got a message showing it hadn't been possible to configure the Enterprise Manager due to the following error:
SEVERE: Failed to allocate port(s) in the specified range(s) for the following process(es): JMS [5540-5559],RMI [5520-5539],Database Control [5500-5519],EM Agent [3938] | [1830-1849]
Refer to the log file at /app/oracle/product/10.2.0/db_1/cfgtoollogs/emca/mki/emca_2009-03-25_12-53-41-PM.log for more details.
Could not complete the configuration. Refer to the log file at /app/oracle/product/10.2.0/db_1/cfgtoollogs/emca/mki/emca_2009-03-25_12-53-41-PM.log for more details.
The message said I could do it using emca script later. I execute that script using
$ ./emca -config dbcontrol db
and I got the same error, as follows:
[oracle@treinamento bin]$ ./emca -config dbcontrol db

Does anybody know how I can fix it and run the emca? I've tryed some google searches but I didn't have any luck.
Thanks a lot.

Hi schavali
I'll try to explain better what's going on with this database Im configuring. So, I installed OEL 5 from the zero, in a new machine, to install Oracle DB Server 10g R2 later on. I did the first step and the second one, which were Install OEL 5 with the packages needed and Oracle Database Server 10g R2. After these installations I went to create a database (I called it mki with SID mki). OK? So, when everything was done, almost at the end of the database creation I got a message that Enterprise Manager failed because it wasnt possible to allocate ports in the specifics ranges for JMS RMI Database Control and Em Agent.
When I run netca I got a message saying the Listener could not be started because another software was using the port 1521.
I did what you suggested. Ignored the listener port and tryed to create manually those ports necessary to run emca.
In the terminal, I typed:
$. emca -config dbcontrol db -repos create -JMS_PORT 5540 -RMI_PORT 5520 -DBCONTROL_HTTP_PORT 5505 -AGENT_PORT 1830
So, the problem is, I didnt get to create any of those ports. I tryed every single port number that wasnt listed as free in /etc vi services and I could not go through. I tryed as a oracle user and with root as well. When I type a port that is not listed in the services, sometimes the error I get says that emca cannot create that port because is out of the range.
Following the procedure to OEL 5 installation, I read it's necessary to select all the packages neeed by Oracle DB 10g R2 and it's also necessary to leave all others unselected. I didnt do that, I installed almost all the packages listed there in the installation. Could be that the problem? That is, if I install OEL 5 again with just the packages needed by Oracle DB could I go through Oracle Enterprise Manager Configuration Assistant? It's just a doubt.
Thanks a lot for your attention
