網(wǎng)站建設(shè)哪家好，找創(chuàng)新互聯(lián)！專注于網(wǎng)頁(yè)設(shè)計(jì)、網(wǎng)站建設(shè)、微信開發(fā)、成都小程序開發(fā)、集團(tuán)企業(yè)網(wǎng)站建設(shè)等服務(wù)項(xiàng)目。為回饋新老客戶創(chuàng)新互聯(lián)還提供了壺關(guān)免費(fèi)建站歡迎大家使用！

說明：
192.168.188.181 為public ip1
192.168.188.182 為public ip2
192.168.188.183 為vip1
192.168.188.184 為vip2

一、修改 DB 監(jiān)聽端口

注意：
1.本文的os是RHEL6.5，DB版本是11.2.0.3.8。
本文非exadata環(huán)境，若是Exadata環(huán)境，請(qǐng)讀Changing Listener Ports On RAC/EXADATA (文檔 ID 1473035.1)
2.本文修改了如下監(jiān)聽器的端口號(hào)，改為1528
集群監(jiān)聽器的端口號(hào)
節(jié)點(diǎn)1本地監(jiān)聽器的端口號(hào)
節(jié)點(diǎn)2本地監(jiān)聽器的端口號(hào)
3.根據(jù) Changing Listener Ports On RAC/EXADATA (文檔 ID 1473035.1),需要在a quiet time來修改監(jiān)聽器端口號(hào)
修改前的檢查

[grid@hosta admin]$ srvctl config listener 
Name: LISTENER 
Network: 1, Owner: grid 
Home:  
End points: TCP:1521 
[grid@hosta admin]$ 
1.僅僅在一個(gè)主機(jī)上執(zhí)行

[grid@hosta admin]$ srvctl modify listener -l LISTENER -p "TCP:1528" 
2.僅僅在一個(gè)主機(jī)上執(zhí)行

[grid@hosta ~]$ srvctl modify scan_listener -p 1528 
3.修改LOCAL_LISTENER僅僅在一個(gè)主機(jī)上執(zhí)行

alter system set local_listener = '(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.188.183)(PORT = 1528))' scope=both sid='orcl1'; 
alter system set local_listener = '(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.188.184)(PORT = 1528))' scope=both sid='orcl2'; 
4.修改remote_listener

alter system set remote_listener='orcl-scan:1528' scope=both; 
5.
在第一個(gè)節(jié)點(diǎn)關(guān)閉本地監(jiān)聽

[grid@hosta ~]$ srvctl stop listener -l LISTENER -n hosta 
修改第一個(gè)節(jié)點(diǎn)的$GI_HOME/network/admin/endpoints_listener.ora文件，將1521改為1528

[grid@hosta admin]$ cat listener.ora--->該文件中不存儲(chǔ)端口號(hào),因此不用修改。 
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 
[grid@hosta admin]$ cat endpoints_listener.ora --->該文件中存儲(chǔ)端口號(hào)，修改本文件即可。 
LISTENER_HOSTA=(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=hosta-vip)(PORT=1528))(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.188.181)(PORT=1528)(IP=FIRST)))) # line added by Agent 
[grid@hosta admin]$

啟動(dòng)第一個(gè)節(jié)點(diǎn)本地監(jiān)聽

[grid@hosta admin]$ srvctl start listener -l LISTENER -n hosta 
在第二個(gè)節(jié)點(diǎn)上進(jìn)行相同的操作。

[grid@hostb ~]$ srvctl stop listener -l LISTENER -n hostb 

修改endpoints_listener.ora文件，不再貼出 
[grid@hostb admin]$ srvctl start listener -l LISTENER -n hostb 
6.確認(rèn)修改效果

[grid@hostb admin]$ srvctl config Listener 
Name: LISTENER 
Network: 1, Owner: grid 
Home:  
End points: TCP:1528

二、 修改 ASM 監(jiān)聽端口

修改 ASM LOCAL_LISTENER 僅僅在一個(gè)主機(jī)上執(zhí)行
sqlplus / as sysasm;
alter system set local_listener = '(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.188.183)(PORT = 1528))' scope=both sid='asm1'; 
alter system set local_listener = '(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.188.184)(PORT = 1528))' scope=both sid='asm2'; 

之后，應(yīng)用程序連接串以及dblink的定義修改端口號(hào)，啟動(dòng)業(yè)務(wù)進(jìn)行測(cè)試即可。
