I've just configured Oracle 11G in CentOS 6.2 using the step by step procedure in http://www.server-world.info/en/note...=oracle11g&f=2
The test database is ok and we can connect through it using oracle client. The problem is, after I decided to change the hostname (name of the server) I encountered this error:
listener refused the connection with the following error ora-12505
when I tried again to connect in oracle client. I've already checked the all including the hosts file. One more thing when I'm trying to check / netstat the port 1521 eventually after my second test it dissapears.
Is there any configuration that needs to be adjusted? sorry for my english grammar and thanks in advance
