HOST command works fine with Oracle Developer 6i.
Since Oracle Developer 9i and 10g are Web-enabled this became obsolete. In replacement of this, you need to install a utility called "Oracle WebUtil". For more Information, please go through the following link oracle.com/technology/products/forms/htdocs/webutil/webutil . htm
the replacement for HOST command is CLIENT_HOST command.

You can use host command in 9i/10g which will interact with the Application server's OS. If you want to access the client machine OS then you have to use WEBUTIL functionality
