I have created a new instance on the same server(tools --> Advanced --> Declare a new instance). The config-<new instance>.xml got created inside the conf directory. How can I connect to the new instance from the client console? A new connection cannot be added because the server URL will be same as the both the instances are on the same server.
Names used must be defined in your DNS. You can also inform the correspondence between a DNS name and an IP address in the c:/windows/system32/drivers/etc/hosts file in Windows and in the /etc/hosts file in Linux. You therefore must modify the connection settings to use this DNS name in order to connect to your chosen instance.
