lsnrctl status - detailed working mechanism

edited Dec 19, 2011 7:27AM in Database Networking (MOSC) 6 commentsAnswered ✓
Dear Gurus,

We are troubleshooting an intermittent problem between Veritas Cluster and Oracle Listener. I need to know exactly what happens when "lsnrctl status" command is executed. Specifically:

1- Does lsnrctl reak listener.ora file to determine the host name and protocol to use?

2- What connections are established between various processes? For example a) does lsnrctl connect to listener? b) does listerner connect to the db? c) does lsnrctl connect to the db?

3- Does lsnrctl use DNS name resolution if it is run on the host that runs listener and db?

Best regards,

Masoud
