I have an Oracle DB working in production for more than a year.
I have my listener working:
[oracle@base admin]$ lsnrctl status LSNRCTL for Linux: Version 126.96.36.199.0 Connecting to (ADDRESS=(PROTOCOL=tcp)(HOST=)(PORT=1521)) STATUS of the LISTENER ------------------------ Alias LISTENER Version TNSLSNR for Linux: Version 188.8.131.52.0 - Production Start Date 02-NOV-2016 14:22:38 Uptime 1 days 20 hr. 3 min. 13 sec Trace Level off Security ON: Local OS Authentication SNMP OFF Listener Log File /o/app/oracle/diag/tnslsnr/base/listener/alert/log.xml Listening Endpoints Summary...

Service "BASEXDB" has 1 instance(s). Instance "BASE", status READY, has 1 handler(s) for this service... The command completed successfully
But I have no
ls /o/app/oracle/product/DB_11.2_SE/dbhome_2/network/admin/ samples shrept.lst tnsnames.ora
This is the content of my
$ cat tnsnames.ora BASE = (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.20.19)(PORT = 1521)) (LOAD_BALANCE = yes) ) (CONNECT_DATA = (SERVICE_NAME = BASE) ) ) ORCL = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.20.20.20)(PORT = 1522)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = orcl) ) )
How is this possible? As far as I know, for the listener to work, I have to have a
I have another Oracle database installed, and if I execute
lsnrctl status, in the output I can see a line containing
Listener Parameter File /o/app/oracle/product/11.2/dbhome/network/admin/listener.ora, and I am not seeing it here. Also I have executed
locate listener.ora, and nothing.
