Hi,
I have installed Oracle Linux 7.1 and have an Oracle 11gR2 database running on it. As part of this I have a standard Oracle Listener running on port 1521.
Through the Desktop GUI for the firewall on this server I have set the Runtime and Permanent Configurations for the 'Public' Zone. In the <PORTS> tab for this zone I have included TCP port 1521.
My TNSPING is now allowing me to reach the port but it is immediately cloning the tnsping with TNS-12537 TNS:connection closed.
Q1. How do I properly open port 1521 at the firewall using the GUI ?
Q2. Can this also be done from command line ?
Q3. This is a internal demo system, so really I do not need the firewall at all. However whereas at Oracle Linux 6, I was easily able to deactive the firewall - I am not quite sure how to do thuis in Oracle Linux 7 - any idea ?
thanks
Jim
