oracle 11g rac 修改监听端口号
本帖最后由 guyeh 于 2013-08-27 17:33 编辑求助：生产RAC环境上有三个实例，现要修改其中一个实例的监听端口号，同事不影响其他实例的业务。从网上找到的资料进行了如下操作未成功，请大侠们指点，生产环境不敢轻易处理。
SQL> show parameter local
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string (DESCRIPTION=(ADDRESS_LIST=(AD
DRESS=(PROTOCOL=TCP)(HOST=10.1
72.19.4)(PORT=1521))))
log_archive_local_first boolean TRUE
parallel_force_local boolean FALSE
SQL> alter system set local_listener='(DESCRIPTION=(ADDRESS_LIST=(ADDRESS=(PROTOCOL=TCP)(HOST=10.172.19.4)(PORT=1522))))' scope =both sid='rac1';

$ ls srvctl
srvctl
$ pwd
/u01/app/oracle/product/11.2/bin
$ ./srvctl stop listener -n rac1
$ ./srvctl stop listener -n rac2
$ ./srvctl start listener -n rac1
$ ./srvctl start listener -n rac2
lsnrctl status检查没有失败的
监听文件的内容
$ cat listener.ora
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
系统环境：redhat 6.2 64bit+oracle11g rac 在listener.ora文件里配置新的监听端口，列如：1522,1523等，和原来的监听端口1521不冲突
举例：
1521端口：
在listener.ora文件里：
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = user-PC)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
1522端口：
LISTENER1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = user-PC)(PORT = 1522))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
1523端口：
LISTENER2 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = user-PC)(PORT = 1523))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
这样就实现了不同的监听端口给不同的应用连接使用。

listener.ora中不用指定端口对应的实例名吗？监听程序工作的时候怎么区分哪个实例是1522端口，而其他实例是1521端口呢
我现在对这个文件中该怎么写有点迷糊。:mrgreen: 你可以在listener.ora文件添加SID_LIST_LISTENER2区分实例名称
我新建了一个监听，
srvctl add listener -l NEW_XDRAC_LISTENER -o $ORACLE_HOME -p 1600 -k 1
srvctl start listener -l NEW_XDRAC_LISTENER
在listener.ora中添加了如下内容
SID_LIST_NEW_XDRAC_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = URPJW)
(ORACLE_HOME = /u01/app/11.2.0/grid)
(SID_NAME = rac1)
)
)
现在的情况是在rac某个节点上只要在tnsnames.ora文件中配置好 tnsping可以成功，但是sqlplus不能连接,jdbc都访问不到，防火墙都开放了的，这是为啥

数据库肯定是起来了的 oracle11g新建监听最好使用图形界面netca，在通过srvctl 加入资源。
