[oracle@node1 ~]$ srvctl config service -d racdb -s service1 -a
service1 PREF: racdb1 AVAIL: racdb2 TAF: basic
[oracle@node1 ~]$ srvctl config service -d racdb
service1 PREF: racdb1 AVAIL: racdb2 从上面的结果可以看出，通过dbca配置service 的taf，会在ocr中存储taf配置信息（仅仅是taf method），在数据库参数文件中会添加service条目，并且在数据字典中添加相应记录，但是数据字典中的taf信息是空的，需要另外添加，如
SQL> begin
2 dbms_service.modify_service(
3 service_name=>'service1',
4 failover_method=>dbms_service.failover_method_basic,
5 failover_type => dbms_service.failover_type_select,
6 failover_retries => 180,
7 failover_delay => 5
8 );
9 end;
10 /

另外，也可以使用srvctl来添加service
[root@node1 ~]# srvctl add service -h
Usage: srvctl add service -d -s -r "" [-a ""] [-P ]
-d Unique name for the database
-s Service name
-r "" List of preferred instances
-a "" List of available instances
-P TAF policy (NONE, BASIC, or PRECONNECT)
Usage: srvctl add service -d -s -u {-r "" | -a ""}
-d Unique name for the database
-s Service name
-u Add a new instance to service configuration
-r Name of new preferred instance
-a Name of new available instance
-h Print usage
[root@node1 ~]# srvctl add service -d racdb -s service2 -r racdb1 -a racdb2 -P BASIC

[oracle@node1 ~]$ srvctl config service -d racdb -a

从这里，可以看出通过srvct添加的service不会在数据库参数和数据字典中添加相应的信息
