Service-Side TAF服务端不需要配置更改客户端实现taf
方法1.客户端配置 (METHOD = basic)节约资源、浪费时间
ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.171.4)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.171.5)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(FAILOVER_MODE =
(TYPE = session)
(METHOD = basic)
(RETRIES = 180)
(DELAY = 5)
)
)
)
方法2.客户端配置 (METHOD = preconnect)节约时间、浪费资源
orcl1 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.171.4)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(FAILOVER_MODE =
(TYPE = select)
(METHOD = preconnect)
(BACKUP = orcl2)
)
)
)
orcl2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 172.16.171.5)(PORT = 1521))
(LOAD_BALANCE = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(FAILOVER_MODE =
(TYPE = select)
(METHOD = preconnect)
(BACKUP = orcl1)
)
)
)
由于客户端要改太过麻烦，现在我们看下怎么不改客户端，直接配置服务端
1.用srvctl 命令配置Service
[oracle@rac1]$srvctl add service -d orcl -s taf -r "orcl1,orcl2" -P BASIC
--这里的orcl是database name，orcl1和orcl2 是instance name。
删除service
#srvctl remove service -d orcl -s taf
2.启动taf服务
[oracle@rac1]srvctl start service -d orcl -s taf
2.1数据库运行时自动运行service
srvctl enable service -d orcl -s taf
SQL> execute dbms_service.modify_service (service_name => ‘taf‘ -
, aq_ha_notifications => true -
, failover_method => dbms_service.failover_method_basic -
, failover_type => dbms_service.failover_type_select -
, failover_retries => 180 -
, failover_delay => 5 -
, clb_goal => dbms_service.clb_goal_long);
删除数据字典里的service信息
begin
dbms_service.delete_service(service_name=>‘taf‘);
end;
/
5.确认修改的参数
col name format a15
col failover_method format a11 heading ‘METHOD‘
col failover_type format a10 heading ‘TYPE‘
col failover_retries format 9999999 heading ‘RETRIES‘
col goal format a10
col clb_goal format a8
col AQ_HA_NOTIFICATIONS format a5 heading ‘AQNOT‘
select name, failover_method,failover_type, failover_retries,goal,
clb_goal,aq_ha_notifications from dba_services where name = ‘taf‘;
6.检查service注册情况：
[oracle@rac1 ~]$ lsnrctl status

The command completed successfully
7.客户端就可以使用Service-SideTAF了：
在客户端TNS 配置：
orcl =
(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST= 172.16.171.6)(PORT=1521))
(CONNECT_DATA=
(SERVER=DEDICATED)(SERVICE_NAME=taf )
)
)
--172.16.171.6是scan ip的地址
测试。。。。。。。。。。
