【Oracle】监听动态注册与静态注册
出自：
client端如果想要连接到远程的数据库服务器，首先数据库服务器必须启动监听器
oracle监听器的配置在$ORACLE_HOME/network/admin/listener.ora,打开这个文件，我们看到配置如下：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC=
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0.1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION=
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
)
动态注册：oracleinstance的pmon进程会在instance启动之后自动将instance_name和service_name注册到1521端口中，我们只需要在listener中修改配置如下，即可实现
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION=
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.102)(PORT =1521))
)
)
注意我们不用修改SID_LIST_LISTENER中的配置
我们首先启动监听器 lsnrctl
LSNRCTL> start

由于我们没有启动instance，所以没有instance的注册信息
启动oracle实例

发现prod服务已经被动态注册进去，其中status为READY说明动态注册成功
静态注册：由于oracle的pmon进程会自动将instance的instance_name和service_name注册到1521端口，如果我们想把instance注册到1521之外的端口，我们只能使用静态注册
下面我们修改listener.ora配置如下：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC=
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0.1)
(PROGRAM = extproc)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION=
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
)
)
staticReg =
(DESCRIPTION_LIST =
(DESCRIPTION=
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.102)(PORT =1522))
)
)
SID_LIST_staticReg =
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME= prod)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0.1)
(SID_NAME = prod)
)
)
我们首先增加了监听配置：
staticReg =
(DESCRIPTION_LIST =
(DESCRIPTION=
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.102)(PORT =1522))
)
)
不同于动态注册，我们必须指定listenername,这里为staticReg
然后增加了SID_LIST关于staticReg的指定配置
SID_LIST_staticReg =
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME= prod)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0.1)
(SID_NAME = prod)
)
)
由于是非标准端口号，我们必须指定SID_LIST配置
保存之后，启动监听：
[oracle@localhost admin]$ lsnrctl

由于我们采用的监听端口是1522，pmon进程是不会自动注册是1521之外的端口
我们需要启动1522端口的监听

由于prod采用的是静态注册，所以状态永远都是UNKNOW
等一会，我们就可以直接采用sqlplus连接，当然客户端必须有对应的tnsname的配置
C:\Users\lei_dong>sqlplus sys/prod@port1522 as sysdba
SQL*Plus: Release 10.2.0.1.0 - Production on 星期三 2月 22 23:58:062012

连接到:
Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 -Production
With the Partitioning, OLAP and Data Mining options
SQL>
连接成功，
最后我们需要在client端配置tnsname,这时无论启动的是1521还是其他端口的监听，差别都不大，基本上只有端口号的差异
