配置一个网络服务名:

Oracle 网络监听配置管理

Oracle 网络监听配置管理

这个 tnsnames.ora 一般是在 客户端生成的。

这个 listener.ora  一般是要在 服务器端生成

测试:使用 ser_name1 服务名连接:

[oracle@localhost admin]$ rlwrap sqlplus / as sysdba;

保存后,进行查看 文件信息 。就可以查到刚新增的 监听信息  list_name1

再配置网络服务名:

当启动监听出现下图的问题:检查其 listener.ora 文件信息都没什么问题的情况下,得要检查linux系统的 hostname是否跟你配置的有差异。

Oracle 网络监听配置管理Oracle 网络监听配置管理

然后把监听配置文件信息的 主机地址改为了 linux 系统的hostname 信息 如下图:

Oracle 网络监听配置管理

这个时候监听启动成功了。而且都是自动注册的服务

3:修改配置文件  文本形式

直接编写这以下的2个文件的信息:

/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora

/u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

[oracle@localhost admin]$ ls
listener1806197PM5534.bak listener.ora samples shrept.lst sqlnet1806197PM5534.bak sqlnet.ora tnsnames.ora
oracle@localhost admin]$ pwd
/u01/app/oracle/product/11.2.0/db_1/network/admin
#---修改前:查看 tnsnames.ora 文件配置信息
[oracle@localhost admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools. SER_ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.242.146)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
) SER_NEWORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.242.146)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = neworcl)
)
) # ---编辑 该文件 oracle@localhost admin]$ vi tnsnames.ora
# ---查看配置后的结果信息
[oracle@localhost admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools. SER_ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.242.146)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
) SER_NEWORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.242.146)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = neworcl)
)
) ser_orcl_1 =
(DESCRIPTION =
(ADDRESS_LIST=
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.242.146)(PORT= 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = orcl)
)
)

#---检查服务配置情况 [oracle@localhost admin]$ rlwrap sqlplus /nolog; SQL*Plus: Release 11.2.0.3.0 Production on Tue Jun 19 20:53:14 2018 Copyright (c) 1982, 2011, Oracle. All rights reserved. @> conn sys/oracle@ser_orcl_1 as sysdba;
Connected.

SYS@ser_orcl_1> quit

注意:如果是修改了 listener.ora 文件的配置信息,则需要进行 lsnrctl reload 的监听重启操作。

配置文件的目录位置

/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
/u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora

服务需要配置 listener.ora

#  1、需要指定侦听器的名称,默认的侦听器的名称为listener
# 2、需要指定侦听器的协议,默认的协议是tcp
# 3、需要指定侦听器的端口,默认的端口为1521 LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = wl)(PORT = 1521))
)
)
) ADR_BASE_LISTENER = /u01/app/oracle

什么是注册



将数据库当中的实例名(instance_name参数下的值)和服务名(service_names 参数下的值)写入到侦听器的操作就叫做注册

注册分类

动态注册

---在instance 启动的时候PMON 进程根据参数文件中的instance_name和service_names 两个参数,将二个参数的值注册到listener 中。
-- instance_name和service_names 两个参数的值什么时候写到listener 中?
-- a)过一段时间,将instance_name,service_names 动态注册到listener 中
-- b) 手动写入到listener 中
alter system register;

静态注册

--将实例名和服务名写到listener 中

如何查看是动态注册?还是静态注册?

---使用lsnrctl status命令查看,如果显示的READY状态,表示动态注册
---使用lsnrctl status命令查看,如果显示的UNKNOWN状态,表示静态注册

动态实验操作

1:动态注册  默认端口 1521

请参考 netmgr 的实现操作方式

2:配置动态注册,指定 service_name 的值,将tnsnames.ora 中的 SERVICE_NAME 进行修改并测试

操作步骤参考文档:

 -- 1) show parameter service_names
alter system set service_names=t1,t2,orcl;
show parameter service_names
-- 2)修改tnsnames.ora中的SERVICE_NAME的值为t1或者t2,然后测试是否能连接
-- 3)alter system set service_names=t1,t2;
show parameter service_names
-- 4)修改tnsnames.ora中的SERVICE_NAME的值为orcl,然后测试是否能连接

具体操作实操:

另外一种方式:如果  把 service_names 中 包含该数据库实例名 togogo 去掉,从原有值集合中 A1 ,A2  ,A3, TOGOGO

删除 togogo 的值,然后在把 tnsnames.ora 中的ww 服务中的service_name的值修改为 togogo后。再重启 监听服务 lsnrctl  reload.

接着用  sqlplus scott/scoot@ww 的方式进行连接。也是可以连接成功的。原因是:该数据库的实例名称 为 togogo.同时其数据库的service_name的值也是为 togogo.

也就是这2者的值一致的。即使再 系统参数中 的service_name中没有指定 togogo 该值。也是可以使用 实例名进行配置tnsname.ora中的某个服务的service_name的值的。反之,如果 service_name 之中的值 和 数据库实例的值再 tnsnames.ora中的配置信息中的 service_name中没有出现,而是其他的值,则 tnsname.ora 中的 服务是无法成功的服务数据库的。

3、配置动态注册,在listener侦听器中设置多个地址(不同端口)

注:该配置方法与oracle数据库的系统参数  local_listener  的值并没有多大关系。该参数是否有值对该方式配置的 tnsnames.ora里的服务没有任何影响。

4、配置动态注册,指定多个侦听器,使用非默认端口(修改local_listener参数,将此参数改为网络服务名)

同理打开 listener2 listener3的监听信息

查看状态信息 发现:只有  LISTENER 有监听到的注册服务信息;其他的 LISTENER1  LISTENER2 LISTENER3 都没有服务注册信息。因为 LISTENER 是动态注册的 。

注意:  LISTENER  LISTENER1  LISTENER2 LISTENER3  在修改了local_listener 这个参数值之后,则默认的 LISTENER的监听器就不能再用了。
