oracle 共享服务连接静态注册服务

默认oracle的共享服务是注册到动态注册服务里面的
sys@PROD3> select * from v$version where rownum=1;

Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production

[oracle@server1 admin]$ cat listener.ora
# listener.ora Network Configuration File: /home/u01/app/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

SID_LIST_LISTENER =
(SID_LIST =
    (SID_DESC =
      (GLOBAL_DBNAME =prod3.oracle.com) --这是静态注册服务
      (ORACLE_HOME = /home/u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME =PROD3)
    )
    (SID_DESC =
      (GLOBAL_DBNAME = PLSExtProc)
      (ORACLE_HOME = /home/u01/app/oracle/product/11.2.0/db_1)
      (SID_NAME = PLSExtProc)
    )
)

LISTENER =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
)

设置共享服务器：
alter system set DISPATCHERS = ‘(PROTOCOL=TCP)(DISPATCHERS=3)‘;

alter system set shared_server_sessions=200 scope=both;

alter system set max_dispatchers=10 scope=both;

alter system set shared_servers=10 scope=both;

alter system set max_shared_servers=30 scope=both;

[oracle@server1 admin]$ lsnrctl services

LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 20-APR-2015 15:46:17

--静态注册服务prod3.oracle.com里面没有dispatcher,动态注册prod3里面有

cat tnsnames.ora

PROD3_S =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (server=shared)
      (SERVICE_NAME =prod3.oracle.com)
    )
)

PROD3 =
(DESCRIPTION =
    (ADDRESS_LIST =
      (ADDRESS = (PROTOCOL = TCP)(HOST = server1)(PORT = 1521))
    )
    (CONNECT_DATA =
      (server=dedicated)
      (SERVICE_NAME =prod3.oracle.com)
    )
)

因为服务prod3.oracle.com 里面没有dispatcher，所以当你作为共享服务连接的时候会报错ORA-12523

[oracle@server1 admin]$ sqlplussys/oracle@prod3_s as sysdba

SQL*Plus: Release 11.2.0.3.0 Production on Mon Apr 20 15:48:49 2015

ERROR:
ORA-12523: TNS:listener could not find instance appropriate for the client
connection

将共享服务注册到静态监听里面
修改参数
alter system set dispatchers=‘(PROTOCOL=TCP)(DISPATCHERS=3)(SERVICE=PROD3,PROD3.ORACLE.COM)‘;
指定service参数

[oracle@server1 admin]$ lsnrctl services

LSNRCTL for Linux: Version 11.2.0.3.0 - Production on 20-APR-2015 15:49:42

现在以共享服务器访问：
[oracle@server1 admin]$ sqlplus sys/oracle@prod3_s as sysdba
