查看監聽配置文件所在的目錄，沒有listener和tnsnames文件
[oracle@up admin]$ pwd /u01/app/oracle/product/11.2.0/network/admin [oracle@up admin]$ ls listener.ora.old samples shrept.lst sqlnet.ora tnsnames.ora.old
啟動監聽：

登錄成功。 靜態注冊 靜態注冊listener不知道數據庫的狀態，根據listener文件裡的配置來設置監聽 listener.ora文件內容如下：
[oracle@up admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/network/admin/listener.ora
# Generated by Oracle configuration tools.
#LISTENER =
# (DESCRIPTION_LIST =
# (DESCRIPTION =
# (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
# (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.231.3)(PORT = 1521))
# )
# )
#ADR_BASE_LISTENER = /u01/app/oracle
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = oracle)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(SID_NAME = oracle)
)
(SID_DESC =
(GLOBAL_DBNAME = ora11g)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0)
(SID_NAME = oracle)
)
)
listener文件中 global_dbname表示對外提供的服務名，需和tnsnames.ora文件中SERVICE_NAME的值一樣 ORACLE_HOME表示數據庫所在的位置 SID_NAME表示數據庫的SID 我的listener文件中sid為orcl的數據庫向外提供了兩個服務名，oracle和ora11g 客戶端登錄時可以用oracle，也可以用ora11g tnsnames.ora文件內容如下：
[oracle@up admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.231.3)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = oracle)
)
)
ORA11G =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.231.3)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ora11g)
)
)
tnsname文件中 HOST表示數據庫服務器的IP地址，或者數據庫服務器的主機名 端口號可以自己設定，但需要在數據庫中修改數據庫裡的參數，默認為1521 SERVICE_NAME的值必須和listener文件裡GLOBAL_DBNAME的值一致 啟動監聽

出現有“Services ‘ora11g’ has 1 instance(s)......"這個信息時，表示監聽程序已經啟動成功了 使用客戶端登錄：

這是使用oracle登錄，然後使用ora11g登錄
[oracle@up ~]$ sqlplus scott/[email protected]/ora11g SQL*Plus: Release 11.2.0.1.0 Production on Fri Oct 30 23:37:44 2015 Copyright (c) 1982, 2009, Oracle. All rights reserved.

使用ora11g也登錄成功
