对监听静态注册配置的理解
Listener.ora 配置文件 中global_dbname 可以随便配置；
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = ora11gbak)----可以自定义
(ORACLE_HOME = /u01/app/ora11/product/11.2.0/dbhome_1)
(SID_NAME = ora11g)
)
(SID_DESC =
(GLOBAL_DBNAME = lixorabak) ----可以自定义
(ORACLE_HOME = /oracle)
(SID_NAME = lixora)
)
)

racle Net Manager Field |
listener.ora File Parameter |
Description |
|
SID |
SID_NAME |
The Oracle system identifier (SID) of the instance. You can obtain the SID value from theINSTANCE_NAME parameter in the initialization parameter file. |
|
Service Name |
GLOBAL_DBNAME |
The database service. While processing a client connection request, the listener tries to match the value of this parameter with the value of the SERVICE_NAMEparameter in the client connect descriptor. If the client connect descriptor uses the SIDparameter, then the listener does not attempt to map the values. This parameter is primarily intended for configurations with Oracle8 databases (where dynamic service registration is not supported for dedicated servers). This parameter may also be required for use with Oracle8i and later database services by some configurations. The value for this parameter is typically obtained from the combination of the DB_NAMEand DB_DOMAIN parameters (DB_NAME.DB_DOMAIN) in the initialization parameter file, but the value can also contain any valid name used by clients to identify the service. 缺省是从pfile 中取 DB_NAME.DB_DOMAIN ; 但是我们也可以自己取一个有意义的名字； |
|
Oracle Home Directory |
ORACLE_HOME |
The Oracle home location of the instance. Without this setting, the listener assumes its Oracle home for the instance. On Linux and UNIX, this setting is optional. On Microsoft Windows, this setting is ignored. The Oracle home specified by theORACLE_HOME parameter inHKEY_LOCAL_MACHINE\SOFTWARE\ORACLE\HOMEID of the Microsoft Windows registry is used. |
