Hello,

I cannot get my listener to start, I have spent hours searching forums and couldn't find any solution.
My goal is to start APEX, but first I have to get listener up&running, when I try, I'm getting:

Welcome to the forum. Please read our OraFAQ Forum Guide and How to use [code] tags and make your code easier to read

Your searches for TNS-12545 must have been very unfortunate. The problem is (as all the references say) that your hostname is either incorrect or not resolving correctly. You are trying to listen on MATULEWI1.emea.xxxxx.net, does this name actually exist and resolve? What does your etc/hosts file and your DNS say about it?

Hi,

thanks for the prompt reply.
Yes, that name exists and that is the name of my machine.
My hosts file:

127.0.0.1 localhost MATULEWI1.emea.xxxxx.net

I've added MATULEWI1.emea.xxxxx.net later on , to check whether it is the cause. (I've x'ed out company name)
DNS are to set to automaticly obtain.

K.

So prove it. With ping and nslookup. Note that it would be highly unusual to have a fixed static address mapped to 127.0.0.1 in your DNS.

Well, running nslookup as you did doesn't tell you a lot about what the DNS thinks is the address of your name, does it?
And pinging localhost doesn't tell you anything, either.

Seriously, you need to learn how to use these tools. Then think about configuring Oracle Net.

I see that you have just edited your post, and therefire obscured what you actually did. Please don't do that, editing posts without explanation causes dreadful confusion, because no-one knows what the truth is.

And please read the links I provided earlier, about using [code] tags.

I'll give you a quick-fix solution:

Edit your listener.ora file and tnsnames.ora file to specify 127.0.0.1 as the address, not that host name. Then everything should work, until you want to connect from an external address.

--update: removed some identification information, which I guess is why OP edited his post before.
