Re: tcp not working for oracle connections

Is something else already listening on port 1575/TCP?

netstat -anf inet |grep 1575

 

If you have the freeware "lsof" utility installed, you could use "lsof -i tcp:1575" to identify the process that is hogging the port.

 

Is castor.merit.com a valid hostname for this host? Does it map to (one of) the IP address(es) of this host in /etc/hosts, and/or in the DNS?
