Oracle listener not running and won't start

Question

I am getting the following errors while from the lsnrctl status command:

C:\\Users\\pna105>lsnrctl stat

 LSNRCTL for 64-bit Windows: Version 11.         


        

Answer 1

I encountered the same problem and reason being: Mine is a personal windows PC. And i have modified the computer name and the same did not reflect in listener.ora. Updating ORACLE_HOME\network\ADMIN\listener.ora with updated host name fixed the issue.
