oracle rac添加service的过程（11gr2版本）
1，手工添加service
su - oracle
[oracle@dtydb3 ~]$ srvctl add service -d epmdb -s srv_epm1 -r epmdb1 -a epmdb2 -P basic -e select -m basic -z 180 -w 5
2，查看service状态和属性
NAME FAILOVER_M FAILOVER_TYPE GOAL CLB_G
-------------------- ---------- ---------------------------------------------------------------- ------------ -----
SYS$BACKGROUND NONE SHORT
SYS$USERS NONE SHORT
epmdb LONG
srv_epm1 BASIC SELECT NONE LONG
[grid@dtydb3 ~]$ crsctl status resource ora.epmdb.srv_epm1.svc -t
--------------------------------------------------------------------------------
NAME TARGET STATE SERVER STATE_DETAILS
--------------------------------------------------------------------------------
Cluster Resources
--------------------------------------------------------------------------------
ora.epmdb.srv_epm1.svc
1 ONLINE ONLINE dtydb3
[grid@dtydb3 ~]$ srvctl status service -d epmdb
Service srv_epm1 is running on instance(s) epmdb1
[grid@dtydb3 ~]$ srvctl config service -d epmdb -s srv_epm1

[grid@dtydb3 ~]$ lsnrctl status

[grid@dtydb3 ~]$
3，修改服务，如果创建不正常的话
修改服务
---srvctl modify service -d epmdb -s srv_epm1 -r epmdb2 -a epmdb1 -P basic -e select -m basic -z 100 -w 2
--删除服务
srvctl remove service -d epmdb -s srv_epm1 -f
4，TAF测试
tnsname.ora配置
tydb_srv_epm1 =
(DESCRIPTION =
(LOAD_BALANCE = NO)
(ADDRESS = (PROTOCOL = TCP)(HOST = db1-vip)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = db2_vip)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = srv_epm1)
)
)
关闭实例1
shutdown immediate
sqlplus system/oracle@tydb_srv_epm1
SQL> select instance_name from v$instance;
INSTANCE_NAME
----------------
epmdb2
成功切换到第二个节点
恢复还原
重启实例1 startup
切换service到实例1
su - oracle
srvctl relocate service -d epmdb -s srv_epm1 -i epmdb2 -t epmdb1
