oracle 共享服務連接靜態注冊服務
默認oracle的共享服務是注冊到動態注冊服務裡面的
sys@PROD3> select * from v$version where rownum=1; BANNER ---------------------------------------------------------------------------------------------------------------------------------------------------------------- Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - 64bit Production [oracle@server1 admin]$ 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.

設置共享服務器：
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 Copyright (c) 1991, 2011, Oracle.

--靜態注冊服務prod3.oracle.com裡面沒有dispatcher,動態注冊prod3裡面有
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) ) )
因為服務prod3.oracle.com 裡面沒有dispatcher，所以當你作為共享服務連接的時候會報錯ORA-12523

將共享服務注冊到靜態監聽裡面
修改參數
alter system set dispatchers='(PROTOCOL=TCP)(DISPATCHERS=3)(SERVICE=PROD3,PROD3.ORACLE.COM)';
指定service參數
