DB deletion causes 'tnsnames.ora' file deletion

edited Nov 28, 2017 11:43PM in Database Networking (MOSC) 7 commentsAnswered ✓

Tnsnames.ora file contains the following entries:

[oracle@rac1 ~]$ cat $ORACLE_HOME/network/admin/tnsnames.ora<br/># tnsnames.ora Network Configuration File: /u01/app/oracle/product/12.2.0/dbhome_1/network/admin/tnsnames.ora<br/># Generated by Oracle configuration tools.<br/><br/>NODEFQDN =<br/>  (ADDRESS = (PROTOCOL = TCP)(Host = rac1.QA-tests.azure)(Port = 1522))<br/><br/><br/>ORCL =<br/>  (DESCRIPTION =<br/>  (ADDRESS = (PROTOCOL = TCP)(HOST = QA-tests-scan.QA-tests.azure)(PORT = 1521))<br/>  (CONNECT_DATA =<br/>  (SERVER = DEDICATED)<br/>  (SERVICE_NAME = orcl)<br/>  )<br/>

  )

If in LOCAL_LISTENER I have indicated NODEFQDN then after deleting that database it causes NODEFQDN  to be also deleted and at last tnsnames.ora file is delete.

Howdy, Stranger!
