【翻译自mos文章】在Oracle单机数据库中定义database service

来源于：

Defining a Database Service with a Stand Alone Database (文档 ID 1260134.1)

APPLIES TO:

Oracle Database - Enterprise Edition - Version 10.2.0.5 to 11.2.0.3 [Release 10.2 to 11.2]

Information in this document applies to any platform.

GOAL

The DBMS_SERVICE package allows the creation, deletion, starting and stopping of services in both RAC and a single instance. Additionally it provides the ability to disconnect all sessions which connect to the instance
with a service name when RAC removes that service name from the instance.

SOLUTION

The DBMS_SERVICE package lets you create, delete, activate and deactivate services for a single instance.



- Functions :

• dbms_service.CREATE_SERVICE , Example:

SQL> exec dbms_service.CREATE_SERVICE(SERVICE_NAME=>'orderentry', NETWORK_NAME=>'db11g')

• dbms_service.MODIFY_SERVICE , Example:

SQL> exec DBMS_SERVICE.MODIFY_SERVICE( -

> service_name => 'o11gr1', -

> goal => DBMS_SERVICE.GOAL_THROUGHPUT, -

> failover_method => DBMS_SERVICE.FAILOVER_METHOD_BASIC, -

> failover_type => DBMS_SERVICE.FAILOVER_TYPE_SELECT, -

> failover_retries => 10, -

> failover_delay => 1, -

> clb_goal => DBMS_SERVICE.CLB_GOAL_LONG);

• dbms_service.START_SERVICE , Example:

SQL> exec dbms_service.START_SERVICE('orderentry')

SQL> show parameter service

It Recommended to have the LOCAL_LISTENER (Database) parameter set for the Database :

If You are using the default local address of TCP/IP, port 1521 :

alter system set LOCAL_LISTENER = '(ADDRESS=(PROTOCOL=TCP)(HOST=HOSTNAME or IP Add)(PORT=1521))' scope=spfile;

If You are using non default local address of TCP/IP, port other than 1521 :

alter system set LOCAL_LISTENER = '(ADDRESS=(PROTOCOL=TCP)(HOST=HOSTNAME or IP Add)(PORT=1522))' scope=spfile;

• dbms_service.STOP_SERVICE , Example:

SQL> exec dbms_service.STOP_SERVICE('orderentry')

• dbms_service.DELETE_SERVICE , Example:

SQL> exec dbms_service.DELETE_SERVICE('orderentry')

-Monitoring



Use the following dictionary views to monitor services:



* dba_services - All defined services

* gv$active_services - All active (started) services



To see what service a session is connected to:

SELECT username, program, machine, service_name FROM gv$session;
