如果安装数据库时，选择Install database software only选项时，安装完数据库软件后，需要进行数据库的创建，那么使用DBCA工具创建数据库前，需要配置监听器和服务，因为使用DBCA建库过程中，如果安装EM则需要启动监听器。
监听器配置
监听器示例
[oracle@sz oracle]$ more product/11.2.0/dbhome_1/network/admin/listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_SZ_PRI =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = szpri)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = szpri)
)
)
SZ_PRI =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = sz.pri.com)(PORT = 1521))
)
ADR_BASE_SZ_PRI = /u01/app/oracle下面详细介绍监听器的配置过程
1、在命令行输入下面的命令，启动Oracle Net Manager图形化工具；
[oracle@sz ~]$ netmgr
2、启动Oracle Net Manager图形化工具；
3、选择Listeners，并点击+按钮后，出现配置监听器名称文本框，输入sz_pri后，点击OK按钮；
4、点击Add Address按钮后，在上面的下拉框中选择Database Services，并点击Add Database按钮；
5、在Global Database Name和SID中输入数据库名称，即前面的ORACLE_SID，szpri，然后在菜单栏点击File下面的Save Network Configuration进 行保存；
6、配置完成后，测试配置情况，下面显示配置成功；

[oracle@sz ~]$TNS服务配置
TNS服务示例
[oracle@sz oracle]$ more product/11.2.0/dbhome_1/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

SZPRI =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = sz.pri.com)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = szpri)
)
)下面详细介TNS服务的配置过程
1、在命令行输入下面的命令，启动Oracle Net Manager图形化工具；
[oracle@sz ~]$ netmgr
2、启动Oracle Net Manager图形化工具，并选择Service Naming，点击+按钮；
3、在Net Service Name输入szpri，点击Next按钮；
4、点击Next按钮进入下一步；
5、在Host Name输入192.168.1.106，点击Next；
6、在Service Name输入szpri，点击Next；
7、点击Finish完成配置，然后在菜单栏点击File下面的Save Network Configuration进行保存；
