If I understand the question correctly, you have installed Oracle 10g software and created a database on your personal computer (I will assume the operating system is Windows). Now you wish to configure a listener. The easiest way to do this is to use the Net Configuration Assistant:
Click on Start --> Oracle – OraDb10g_home1 --> Configuration and Migration Tools --> Net Configuration Assistant.
This starts up a wizard where you can choose various Oracle Net configuration tasks. Click on the "Listener configuration" option and follow the prompts.
When completed, a service should be created that is named something similar to OracleOraDb10g_home1TNSListener, and it should have been started. If the service exists but has not been started, right-click on the service and choose "Start."
