Getting IP address, version, server names, etc. with SQL

such things using a SQL statment?

You won't be able to get all of the information you are seeking with a simple SQL statement. But you can get some of it. For instance:

SELECT instance_name,host_name,version 
FROM v$instance;

This will give you the instance name, the host name of the database server and the Oracle version you are running.

To get the IP address of the database server, you will need to code an Java routine which will run an external 'nslookup' command on the database server. You'll pass the host_name you gathered from above. If you want to find the OS version you are running, you can use the same Java routine, but instead of running the 'nslookup' command, you'll need to run 'winver' for Windows or 'uname -a' for most Unix flavors.
