oracle 的2种访问方式
动态注册（Dynamic service Registration）
service_names =Global database name=db_name.db_domain
instance_name 默认是SID
修改spfileSID.ora文件方法如下：
先查看参数：
SQL> show parameter service
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
service_names string guo
SQL> show parameter instance
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
active_instance_count integer
cluster_database_instances integer 1
instance_groups string
instance_name string guo
增加这2个参数
SQL> alter system set service_names='guo' scope=spfile;
System altered.
SQL> alter system set instance_name='guo' scope=spfile;
System altered.
然后在strings spfileSID.ora。
动态注册只需要在spfileSID.ora中注册上上述的2个参数就可以直接连接到数据库了。然后删除掉$ORACLE_HOME/network/admin中的listener.ora文件。
先查看客户端的tnsnames.ora中的信息
# tnsnames.ora Network Configuration File: E:\oracle\product\10.2.0\client_1\network\admin\tnsnames.ora
# Generated by Oracle configuration tools.GUO =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.205)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = guo)
)
)
c:\>sqlplus hr/hr@guo
即可成功连接到数据库。
查看监听状态如下：
[oracle@oral admin]$ lsnrctl status

静态注册（Static service Registration）
如果要使用Oracle Enterprise Manager (OEM)的话，就必须要使用静态注册（Static service configuration）
listener name listener
Port 1521
Protocols TCP/IP
SID name default instance
Host name default host name
牛人可以记事本手工写，本人只有netca或者Netmanager的方式来搞了。
在XWindows下，直接netca，直接Next到头即可（但是也要看实际情况）。
netca只能简单的配置下。
view listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/n
etwork/admin/listener.ora
# Generated by Oracle configuration tools.SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
)LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.205)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)
通过 net manager可以配置更多参数。
直接netmgr。
其中 Global database name = db_name.db_domain
本人的参数如下：
show parameter name
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_file_name_convert string
db_name string guo
db_unique_name string guo
global_names boolean FALSE
instance_name string guo
lock_name_space string
log_file_name_convert string
service_names string guo
SQL> show parameter doma
SQL> show parameter doma
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_domain string
所以 我的Global database name就是 guo
通过net manager修改过后listener.ora如下
# listener.ora Network Configuration File: /u01/app/oracle/product/10.2.0/db_1/n
etwork/admin/listener.ora
# Generated by Oracle configuration tools.SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = guo)
(ORACLE_HOME = /u01/app/oracle/product/10.2.0/db_1)
(SID_NAME = guo)
)
)LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.205)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))
)
)TRACE_LEVEL_LISTENER = USER
监听如下：
