关键步骤：手工添加服务名A并启动（已验证默认的服务名测试验证无法实现Failover）
[oracle@db90 ~]$ srvctl add service -db orcl -service A -preferred cdb11,cdb12 -pdb pdb1 [oracle@db90 ~]$ srvctl start service -db orcl -service A
完整步骤：
1.确认环境信息
1.1 服务端信息：
SQL> show parameter name NAME TYPE VALUE------------------------------------ ----------- ------------------------------cdb_cluster_name string orcl cell_offloadgroup_name stringdb_file_name_convert stringdb_name string orcl db_unique_name string orcl global_names boolean FALSEinstance_name string cdb11 lock_name_space stringlog_file_name_convert stringpdb_file_name_convert stringprocessor_group_name stringNAME TYPE VALUE------------------------------------ ----------- ------------------------------service_names string orcl SQL> show con_id CON_ID------------------------------1SQL> show pdbs CON_ID CON_NAME OPEN MODE RESTRICTED---------- ------------------------------ ---------- ---------- 2 PDB$SEED READ ONLY NO 3 PDB1 READ WRITE NO 4 PDB2 READ WRITE NO
1.2 客户端tnsnames.ora配置：
PDB= (DESCRIPTION = (ADDRESS_LIST = (LOAD_BALANCE = off) (FAILOVER=on) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.90)(PORT = 1521)) (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.92)(PORT = 1521)) ) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = A) (FAILOVER_MODE = (TYPE = SELECT) (METHOD = BASIC) (RETRIES = 180) (DELAY = 5) ) ) )
2.手工添加服务并启动
[oracle@db90 ~]$ srvctl add service -db orcl -service A -preferred cdb11,cdb12 -pdb pdb1 [oracle@db90 ~]$ srvctl start service -db orcl -service A
查看服务状态，看到已经成功增加了ora.orcl.a.svc：

3.测试客户端连接到服务端
[oracle@db01 admin]$ sqlplus scott/tiger@pdb SQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 1 17:35:08 2019Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production SQL> show parameter name NAME TYPE VALUE------------------------------------ ----------- ------------------------------cdb_cluster_name string orcl cell_offloadgroup_name stringdb_file_name_convert stringdb_name string orcl db_unique_name string orcl global_names boolean FALSEinstance_name string cdb11 lock_name_space stringlog_file_name_convert stringpdb_file_name_convert stringprocessor_group_name stringNAME TYPE VALUE------------------------------------ ----------- ------------------------------service_names string orcl
4.关闭实例1的pdb1
[oracle@db90 ~]$ sqlplus / as sysdba SQL*Plus: Release 12.2.0.1.0 Production on Fri Mar 1 18:21:33 2019 Copyright (c) 1982, 2016, Oracle. All rights reserved.

5.客户端再次连接到服务端
[oracle@db01 admin]$ sqlplus scott/tiger@pdb SQL*Plus: Release 11.2.0.4.0 Production on Fri Mar 1 18:23:48 2019Copyright (c) 1982, 2013, Oracle. All rights reserved. Connected to: Oracle Database 12c Enterprise Edition Release 12.2.0.1.0 - 64bit Production SQL> show parameter name NAME TYPE VALUE------------------------------------ ----------- ------------------------------cdb_cluster_name string orcl cell_offloadgroup_name stringdb_file_name_convert stringdb_name string orcl db_unique_name string orcl global_names boolean FALSEinstance_name string cdb12 lock_name_space stringlog_file_name_convert stringpdb_file_name_convert stringprocessor_group_name stringNAME TYPE VALUE------------------------------------ ----------- ------------------------------service_names string orcl SQL>
6.测试完成重新启动实例1的pdb1
启动节点1的服务就会拉起实例1的pdb1:
[oracle@db90 ~]$ srvctl start service -db orcl -service A -node db90
整个测试过程已完成。
