测试环境：redhat 6.5, oracle 11G
总共要修改3个地方
1）修改host
[root@NCDB /]# vi /etc/hosts
172.0.0.112 NCBD
127.0.0.1 localhost NCDB localhost4 localhost4.localdomain4
::1 localhost NCDB localhost6 localhost6.localdomain6
172.0.0.112 localhost NCDB localhost4 localhost4.localdomain4
2）修改network
[root@NCBD /]# vi /etc/sysconfig/network
HOSTNAME=B=NCDB
NETWORKING=yes
HOSTNAME=NCDB
3）修改oracle的listener.ora和tnsnames.ora文件找自己的安装路径
[oracle@NCDB~]$
vi /opt/oracle/product/12.2.0/dbhome/network/admin/listener.ora
(ADDRESS = (PROTOCOL = TCP)(HOST = NCDB)(PORT = 1521))
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = NCDB)(PORT = 1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(SID_NAME = orcl)
)
)
tnsnames.ora文件修改
vi /opt/oracle/product/12.2.0/dbhome/network/admin/tnsnames.ora
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.0.0.112)(PORT = 1521))
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.0.0.112)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
