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

sys@EPMDB1(10.4.124.233)> select name, failover_method, failover_type, goal, clb_goal from dba_services;

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
