That's correct. However, the path called out in that document, $ORACLE_HOME/host_sid/, does not exist.

Could you please share with us -one more time- the reason why you are trying to install Ora10g while not being a DBA?

I don't think I have shared this with you before, as it hasn't been asked: I'd like to learn as much as I can about Oracle. But does that truly matter?

I have installed Database 10g on Windows systems multiple times, and I've never had this trouble before doing an install on Linux.

Seems you have all the ports in the specified range occupied by other apps or I am wrong? So when u try to config the em, it tries to allocate a port in this range but fails. U cannot change the port, since it is not set at all. The successfull emca will create the directory u miss.
So to summarize, emca tries to set dbconsole on some port in the specified ranges, but can't find one free. Maybe OS prevents it somehow, maybe they are just occupied. The easiest is to get a clean machine, reinstall the OS and start from scrach

Thanks Bore. According to netstat, my system doesn't have anything running on any of the ports specified by Oracle. I supposed that doesn't necessarily mean that the ports aren't somehow reserved, but I'm not sure how to investigate that. In any case, it's highly unlikely that all of the necessary ports are already being used by something else. If possible, please let me know of a way to verify what ports are "reserved" by the system. I'm trying to install on my Linux workstation, so I'd rather not wipe out the machine and reinstall the OS unless absolutely necessary.

Thank you.

You could try usign telnet to connect to the port, is there a firewall involved?

My guess is that craigdba means for me to try to telnet to one of the ports that Oracle is complaining about ... if the connection is refused, to port is not being listened to.
$ telnet localhost 1521
Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused


I am behind a firewall here, but since I'm trying to install on my own system, I don't believe the firewall is a factor (or is it?).

I still haven't been able to figure this out.

I noticed in the $ORACLE_HOME/install/ directory a file called portlist.ini, which contains the following:

Code:

---

iSQL*Plus HTTP port number =5560

---

Are we supposed to edit this file before installation (even though the directory doesn't yet exist) and enter values for all necessary ports?

See,
That turns more to Linux question than Oracle one. There are some linux staff such as SELINUX, also some ports are resevred and can be allocated only by processes owned by root, but that comes out of my Linux knowledge and I would not comment on that.

Right: there's SELinux (disabled on my system) and /etc/services (none of the Oracle ports are listed in my /etc/services), which are part of Linux. But this $ORACLE_HOME/install/portlist.ini comes from Oracle and must be created either during installation. I found this in one of the Oracle docs:
The portlist.ini file lists the port numbers assigned during the [application server] installation.

So, in my case, only the iSQL*Plus port number was assigned? Why not the others?
