简介： 对于Oracle 网络配置，我们通常通过negmgr或者netca来完成客户端连接到数据库实例。而对于连接到ASM实例，同样可以实现从客户端来进行连接。

对于Oracle 网络配置，我们通常通过negmgr或者netca来完成客户端连接到数据库实例。而对于连接到ASM实例，同样可以实现从客户端来进行连接。不过Oracle并未为我们提供工具来完成配置，我们可以通过手动配置监听以及客户端tnsnames来实现。本文对此给出描述与示例。

1、服务器端、客户端的环境  
  #服务器端环境，host信息  
  oracle@bo2dbp:~> cat /etc/hosts |grep vip  
  192.168.7.61   bo2dbp-vip.2gotrade.com    bo2dbp-vip  
  192.168.7.62   bo2dbs-vip.2gotrade.com    bo2dbs-vip 
  
  #操作系统及Oracle版本 
  oracle@bo2dbp:~> cat /etc/issue

 Welcome to SUSE Linux Enterprise Server 10 SP3 (x86_64) - Kernel \r (\l).
 
 oracle@bo2dbp:~> sqlplus -v

  #服务器端环境，集群信息  
  oracle@bo2dbp:~> ./crs_stat.sh   
   Resource name                                Target     State

 #客户端信息  
 C:\Users\robinson.cheng>systeminfo
 
 Host Name:                 PC39
 OS Name:                   Microsoft Windows 7 Professional
 OS Version:                6.1.7600 N/A Build 7600
 OS Manufacturer:           Microsoft Corporation
 System Type:               x64-based PC
 
 C:\Users\robinson.cheng>sqlplus -v
 
 SQL*Plus: Release 10.2.0.3.0 - Production

2、监听器的状态   
 oracle@bo2dbs:~> lsnrctl status LISTENER_BO2DBS | grep ASM
 Service "+ASM" has 1 instance(s).     #可以看到ASM实例处于BLOCKED状态
   Instance "+ASM2", status BLOCKED, has 1 handler(s) for this service...
 Service "+ASM_XPT" has 1 instance(s).
   Instance "+ASM2", status BLOCKED, has 1 handler(s) for this service...

3、分配ASM SID
  #使用下面的ASM配置信息来修改监听器配置文件
 Item                                          Node1            Node2
 ------                                        --------         -----------
 hostname                                      bo2dbp           bo2dbs 
 Oracle SID                                    GOBO4A           GOBO4B
 ASM SID                                       +ASM1            +ASM2
 ASM Global DB Name (service name)             +ASM             +ASM

4、修改监听配置文件listener.ora
 #对于监听器的配置，仅仅是增加子项SID_DESC
 #下面是增加之后所看到的内容
 oracle@bo2dbp:~> more $ORACLE_HOME/network/admin/listener.ora
 # listener.ora.bo2dbp Network Configuration File: /u01/oracle/db/network/admin/listener.ora.bo2dbp
 # Generated by Oracle configuration tools.
 LISTENER_BO2DBP =
   (DESCRIPTION_LIST =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = bo2dbp-vip.2gotrade.com)(PORT = 1521)(IP = FIRST))
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.51)(PORT = 1521)(IP = FIRST))
     )
   )
 
 SID_LIST_LISTENER_BO2DBP =
   (SID_LIST =
     (SID_DESC =
       (SID_NAME = PLSExtProc)
       (ORACLE_HOME = /u01/oracle/db)
       (PROGRAM = extproc)
     (SID_DESC =          #这整个SID_DESC项即为ASM1实例新增的条目
       (SID_NAME = +ASM1)
       (GLOBAL_DBNAME  = +ASM)
       (ORACLE_HOME = /u01/oracle/db)
     )
   )
  
 oracle@bo2dbs:~> more $ORACLE_HOME/network/admin/listener.ora
 # listener.ora.bo2dbs Network Configuration File: /u01/oracle/db/network/admin/listener.ora.bo2dbs
 # Generated by Oracle configuration tools.
 LISTENER_BO2DBS =
   (DESCRIPTION_LIST =
     (DESCRIPTION =
       (ADDRESS = (PROTOCOL = TCP)(HOST = bo2dbs-vip.2gotrade.com)(PORT = 1521)(IP = FIRST))
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.52)(PORT = 1521)(IP = FIRST))
     )
   )
 
 SID_LIST_LISTENER_BO2DBS =
   (SID_LIST =
     (SID_DESC =
       (SID_NAME = PLSExtProc)
       (ORACLE_HOME = /u01/oracle/db)
       (PROGRAM = extproc)
     )
     (SID_DESC =                   #这整个SID_DESC项即为ASM2实例新增的条目
       (SID_NAME = +ASM2)
       (GLOBAL_DBNAME  = +ASM)
       (ORACLE_HOME = /u01/oracle/db)
     )
   )

5、重启监听器
 oracle@bo2dbp:~> srvctl stop listener -n bo2dbp
 oracle@bo2dbp:~> srvctl start listener -n bo2dbp
 oracle@bo2dbp:~> srvctl stop listener -n bo2dbs
 oracle@bo2dbp:~> srvctl start listener -n bo2dbs
  
  #查看监听器的状态 
 oracle@bo2dbp:~> lsnrctl status LISTENER_BO2DBP | grep ASM
 Service "+ASM" has 2 instance(s).  #可以看到多处了一个为UNKNOWN状态，表明使用了静态方式注册
   Instance "+ASM1", status UNKNOWN, has 1 handler(s) for this service...
   Instance "+ASM1", status BLOCKED, has 1 handler(s) for this service...
 Service "+ASM_XPT" has 1 instance(s).
   Instance "+ASM1", status BLOCKED, has 1 handler(s) for this service...
 
 oracle@bo2dbs:~> lsnrctl status LISTENER_BO2DBS | grep ASM
 Service "+ASM" has 2 instance(s).  #示例2上监听器状态也多出了一个为UNKNOWN状态的+ASM2实例
   Instance "+ASM2", status UNKNOWN, has 1 handler(s) for this service...
   Instance "+ASM2", status BLOCKED, has 1 handler(s) for this service...
 Service "+ASM_XPT" has 1 instance(s).
   Instance "+ASM2", status BLOCKED, has 1 handler(s) for this service...

6、配置客户端tnsnames
 #Windons 客户端tnsnames.ora添加如下配置条目
 GOBO4_ASM1 =
   (DESCRIPTION =
     (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.61)(PORT = 1521))
     )
     (CONNECT_DATA =
       (SERVICE_NAME = +ASM)
     )
   )
 
 GOBO4_ASM2 =
   (DESCRIPTION =
     (ADDRESS_LIST =
       (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.62)(PORT = 1521))
     )
     (CONNECT_DATA =
       (SERVICE_NAME = +ASM)
     )
   )    

7、测试连接到ASM实例   

 C:\Users\robinson.cheng>sqlplus -S sys/oracle@GOBO4_ASM1 as sysdba @inst
 
 INSTANCE_NAME    HOST_NAME                      STATUS
 ---------------- ------------------------------ ------------
 +ASM1            bo2dbp                         STARTED
 
 
 C:\Users\robinson.cheng>sqlplus -S sys/oracle@GOBO4_ASM2 as sysdba @inst
 
 INSTANCE_NAME    HOST_NAME                      STATUS
 ---------------- ------------------------------ ------------
 +ASM2            bo2dbs                         STARTED
