在使用srvctl创建service时,需要注意TAF策略选项必须通过dbms_service包来配置。下面例子演示了如何创建一个服务felix_ora: 1.创建之前查看系统现有的service: SQL show parameter service NAME TYPE VALUE ------------------------------------ -------

在使用srvctl创建service时,需要注意TAF策略选项必须通过dbms_service包来配置。下面例子演示了如何创建一个服务felix_ora:

1.创建之前查看系统现有的service:

SQL> show parameter service

NAME TYPE VALUE

------------------------------------ -----------------------------------------

service_names string felix

SQL>

2.使用srvctl创建felix_ora服务;

[oracle@felix1 ~]$ srvctl add service -d felix -s felix_ora -r felix1 -a felix2 -P BASIC

[oracle@felix1 ~]$

[oracle@felix1 ~]$ srvctl config service -d felix-a

felix_ora PREF: felix1 AVAIL: felix2 TAF: BASIC

[oracle@felix1 ~]$ srvctl status service -d felix

Service felix_ora is not running.

[oracle@felix1 ~]$

3.确认服务创建成功,以下标红部分说明服务已经作为一项CRS Resource注册到CRS中,但是目前没有启动。

[oracle@felix1 ~]$ crs_stat -t -v

Name Type R/RA F/FT Target State Host

----------------------------------------------------------------------

ora.felix.db application 0/0 0/1 ONLINE ONLINE felix1

ora....x1.inst application 0/5 0/0 ONLINE ONLINE felix1

ora....x2.inst application 0/5 0/0 ONLINE ONLINE felix2

ora...._ora.cs application 0/0 0/1 OFFLINE OFFLINE

ora....ix1.srv application 0/0 0/0 OFFLINE OFFLINE

ora....SM1.asm application 0/5 0/0 ONLINE ONLINE felix1

ora....X1.lsnr application 0/5 0/0 ONLINE ONLINE felix1

ora.felix1.gsd application 0/5 0/0 ONLINE ONLINE felix1

ora.felix1.ons application 0/3 0/0 ONLINE ONLINE felix1

ora.felix1.vip application 0/0 0/0 ONLINE ONLINE felix1

ora....SM2.asm application 0/5 0/0 ONLINE ONLINE felix2

ora....X2.lsnr application 0/5 0/0 ONLINE ONLINE felix2

ora.felix2.gsd application 0/5 0/0 ONLINE ONLINE felix2

ora.felix2.ons application 0/3 0/0 ONLINE ONLINE felix2

ora.felix2.vip application 0/0 0/0 ONLINE ONLINE felix2

[oracle@felix1 ~]$

4.配置服务自动启动

[oracle@felix1 ~]$ srvctl enable service -d felix-s felix_ora

PRKP-1018 : Service felix_ora already enabled.

[oracle@felix1 ~]$

5.启动这个服务

[oracle@felix1 ~]$ srvctl start service -d felix -s felix_ora

[oracle@felix1 ~]$

[oracle@felix1 ~]$ srvctl status service -d felix -s felix_ora

Service felix_ora is running on instance(s) felix1

[oracle@felix1 ~]$

6.确认服务状态;

[oracle@felix2 ~]$ crs_stat -t -v

Name Type R/RA F/FT Target State Host

----------------------------------------------------------------------

ora.felix.db application 0/0 0/1 ONLINE ONLINE felix1

ora....x1.inst application 0/5 0/0 ONLINE ONLINE felix1

ora....x2.inst application 0/5 0/0 ONLINE ONLINE felix2

ora...._ora.cs application 0/0 0/1 ONLINE ONLINE felix1

ora....ix1.srv application 0/0 0/0 ONLINE ONLINE felix1

ora....SM1.asm application 0/5 0/0 ONLINE ONLINE felix1

ora....X1.lsnr application 0/5 0/0 ONLINE ONLINE felix1

ora.felix1.gsd application 0/5 0/0 ONLINE ONLINE felix1

ora.felix1.ons application 0/3 0/0 ONLINE ONLINE felix1

ora.felix1.vip application 0/0 0/0 ONLINE ONLINE felix1

ora....SM2.asm application 0/5 0/0 ONLINE ONLINE felix2

ora....X2.lsnr application 0/5 0/0 ONLINE ONLINE felix2

ora.felix2.gsd application 0/5 0/0 ONLINE ONLINE felix2

ora.felix2.ons application 0/3 0/0 ONLINE ONLINE felix2

ora.felix2.vip application 0/0 0/0 ONLINE ONLINE felix2

[oracle@felix2 ~]$

说明已经全部启动了;

新建的服务会自动添加到初始化参数文件中:

SQL> show parameter service

NAME TYPE VALUE

------------------------------------ -----------------------------------------

service_names string felix, felix_ora

SQL>

7.修改service的TAF配置,需要使用dbms_service.modify_service

begin

dbms_service.modify_service(service_name => 'felix_ora',

failover_method =>dbms_service.failover_method_basic,

failover_type =>dbms_service.failover_type_select,

failover_retries => 180,

failover_delay => 5);

end;

/

PL/SQL procedure successfully completed.

8.确认以生效

Set lines 1000 pages 1000

col name for a50

col clb_goal for a15

col FAILOVER_METHOD for a15

col failover_type for a20;

SQL> selectname,failover_method,failover_type,clb_goal from dba_services;

NAME FAILOVER_METHOD FAILOVER_TYPE CLB_GOAL

----------------------------------------------------------------- -------------------- ---------------

SYS$BACKGROUND SHORT

SYS$USERS SHORT

seeddataXDB LONG

seeddata.regress.rdbms.dev.us.oracle.com LONG

felixXDB LONG

felix LONG

taf_server LONG

taf_srvctl LONG

felix_ora BASIC SELECT LONG

9 rows selected.

[oracle@felix1 ~]$ srvctl config service -d felix -a

felix_ora PREF: felix1 AVAIL: felix2 TAF: BASIC

[oracle@felix1 ~]$
