Welcome to LSNRCTL, type "help" for information.

LSNRCTL> services

Now, in the above quote, connections refused is 27. When connections are refused, is error information logged in the listener.log file? If so, what is the format, to identify it in the listener.log file of 17mb?

Normally, the listener.log file has the following similar entries...
21-MAR-03 11:00:33 * (CONNECT_DATA=(SID=blaze)(CID=(PROGRAM=)(HOST=__jdbc__)(USER=oracle))) * (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.66.254)(PORT=61401)) * establish * blaze * 0
