Oracle Database Discussions

I have two 10g R2 databases installed on a 32-bit Linux box (ubuntu to be exact).

I installed the first DB as ORCL (SID=TEST) using the installer (runInstaller), everything was fine, I can access the Enterprise Manager home page from different user accounts on the same box, as well as from other windows boxes on the network, using the url of http://xxx.xxx.xxx.xxx:1158/em. The port number was assigned by the installer.

Then I installed the the second DB as ORCL2 (SID=TARGET) using dbca. Everything was fine until it tried to configure the enterprise manager for the DB. It complained couldn't find any port. I let the installation finish. The database was OK, I can connect to it through Oracle SQLDeveloper. Then I re-launched dbca (from the oracle user account) to re-configure the database. This time the configuration finished without any problem. A port number of 5550 was assigned for the EM home page. I then was able to connect to the 2nd DB's EM from the oracle user account using the url of http://xxx.xxx.xxx.xxx:5550/em. However, I cannot do the same thing using any other user accounts on the same box, nor could I access the 2nd DB (ORCL2)'s EM home page from any other windows box on the network. In any case, it would just say can't establish a connection to the server at xxx.xxx.xxx.xxx:5550. In the meanwhile, the 1st DB (ORCL) I still don't have any problem to access its EM home page.

Running "emctl status dbconsole" from the oracle account does not reveal any problem.

Would appreciate if anyone could help.
