Oracle的監(jiān)聽器服務(wù)注冊方式有兩種，分別為動態(tài)和靜態(tài),本文將詳細介紹這兩種,需要的朋友可以參考下

Oracle的監(jiān)聽器服務(wù)注冊方式有兩種，分別為動態(tài)和靜態(tài)。通過動態(tài)注冊的服務(wù)在lsnrctl status時顯示的狀態(tài)為ready，靜態(tài)的服務(wù)為unknown。
11g2以前的版本，監(jiān)聽器通過listener.ora文件進行配置。在11g2版本中，監(jiān)聽器的配置方式發(fā)生了變化，增加了一個新的配置文件endpoints_listener.ora，并且此文件和原來的listener.ora文件都轉(zhuǎn)移到$GRID_HOME/network/admin目錄下了。

11g2的監(jiān)聽器的配置信息保存在$GRID_HOME/network/admin/listener.ora和endpoints_listener.ora兩個文件中。
文件endpoints_listener.ora的內(nèi)容如下：
.ora代碼

復制代碼代碼如下:

 
LISTENER_SERV2= 
(DESCRIPTION= 
( 
ADDRESS_LIST= 
(ADDRESS=(PROTOCOL=TCP)(HOST=xxdb2-vip)(PORT=1551)) 
(ADDRESS=(PROTOCOL=TCP)(HOST=10.10.10.100)(PORT=1551)(IP=FIRST)) 
) 
) 

文件listener.ora的內(nèi)容如下：
.ora代碼

復制代碼代碼如下:

 
LISTENER=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER)))) # line added by Agent 
LISTENER_SCAN1=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=IPC)(KEY=LISTENER_SCAN1)))) # line added by Agent 
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_SCAN1=ON # line added by Agent 
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent 
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER_WFG=ON # line added by Agent 

.ora代碼
##靜態(tài)服務(wù)注冊添加條目

復制代碼代碼如下:

 
SID_LIST_LISTENER = 
(SID_LIST = 
(SID_DESC = 
(GLOBAL_DBNAME = servdb) 
(ORACLE_HOME = /u01/oracle/app/oracle/product/10.2.0/db) 
(SID_NAME = servdb1) 
) 
) 

如果需要添加靜態(tài)注冊的服務(wù)，和以前版本一樣是在listener.ora文件中添加相應(yīng)的條目。
使用lsnrctl status listener檢查監(jiān)聽器狀態(tài)，如下：
Log代碼

復制代碼代碼如下:

在11g2的grid infrastructure上安裝oracle 10g，10g的監(jiān)聽器配置文件也要采用$GRID_HOME/network/admin下的文件。
但需要做一個折中操作，將10g的$ORACLE_HOME/network/admin下listener.ora文件設(shè)置為$GRID_HOME/network/admin下endpoints_listener.ora的文件鏈接。
