A listener may listen for any number of database services. To configure a listener to handle requests for database services, you will need to provide information that the listener needs to identify and then start those services. You do this by specifying the following:
Add Database To add the database service that you have just configured, click on the Add Database tab on the bottom of the tab panel. Remove Database To remove the database service that you have just configured, click on the Remove Database tab on the bottom of the tab panel. Back to "Oracle Net8 Assistant HELP Contents"
