How to modify Oracle_hostname after installing the Oracle database on Linux

1, modify the Hosts file, add JTWF to the native IP address mapping:

[[email protected] home] # gedit/etc/hosts

The last behavior added:

127.0.0.1 Span class= "Hljs-selector-tag" >localhost localhost .localdomain localhost4 localhost4.localdomain4 ::1 localhost localhost.localdomain localhost6 localhost6 .localdomain616.54 .136.81  JTWF                 

2, modify/etc/sysconfig/network add as follows:

[[email protected] home] # gedit/etc/sysconfig/networknetworking=Yeshostname=jtwf   

3, modify the Listener.ora

/home/oracle/product/11.2/db_1/network/admin/listener.ora   

Change host changed from Host=localhost to HOST=JTWF (optional):

/home/oracle/product/11.2/db_1/network/admin/listener.ora# Generated by Oracle configuration tools. LISTENER = (Description_list = (/home/oracle    

4, Tnsnames.ora file is not modified also can, I did not modify

/home/oracle/product/11.2/db_1/network/admin/tnsnames.ora   

/home/oracle/product/11.2/db_1/network/admin/tnsnames.ora# Generated by Oracle configuration tools. ORCL = (1521)) (Connect_data = (SERVER = dedicated) (service_name = ORCL     )))
