1、检测准备库是否能正常切换
主库：
alter database commit to switchover to physical standby with session shutdown;
备库：
alter database commit to switchover to primary with session shutdown;
alter database open;
主库：
startup;
2、确保主备库都是spfile启动
主库：
SYS@dgpri>show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +DATA/ZZZDGPRI/parameterfile/s
pfile.276.1025373149
**备库：**
SYS@dgphy>show parameter spfile;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
spfile string +DATADG/ZZZDGPHY/parameterfile
/spfile.258.1025389845
3、修改dg_broker_start参数为TRUE
主库：
SYS@dgpri>show parameter dg_broker;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1 string /u01/app/oracle/product/19.2.0
.0.0/dbhome_1/dbs/dr1ZZZDGPRI.
dat
dg_broker_config_file2 string /u01/app/oracle/product/19.2.0
.0.0/dbhome_1/dbs/dr2ZZZDGPRI.
dat
dg_broker_start boolean FALSE
SYS@dgpri>alter system set dg_broker_start = true;
System altered.
SYS@dgpri>host ps -ef | grep dmon
oracle 35590 1 0 18:39 ? 00:00:00 ora_dmon_dgpri
oracle 35639 9449 0 18:39 pts/2 00:00:00 /bin/bash -c ps -ef | grep dmon
oracle 35641 35639 0 18:39 pts/2 00:00:00 grep dmon
备库：
SYS@dgphy>show parameter dg_broker;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
dg_broker_config_file1 string /u01/app/oracle/product/19.2.0
.0.0/dbhome_1/dbs/dr1ZZZDGPHY.
dat
dg_broker_config_file2 string /u01/app/oracle/product/19.2.0
.0.0/dbhome_1/dbs/dr2ZZZDGPHY.
dat
dg_broker_start boolean FALSE
SYS@dgphy>alter system set dg_broker_start = true;
System altered.
SYS@dgphy>host ps -ef | grep dmon
oracle 14377 1 0 18:39 ? 00:00:00 ora_dmon_dgphy
oracle 14410 8169 0 18:40 pts/2 00:00:00 /bin/bash -c ps -ef | grep dmon
oracle 14412 14410 0 18:40 pts/2 00:00:00 grep dmon
4、修改dg_broker参数文件位置
主库：
SYS@dgpri>alter system set dg_broker_config_file1 = '+DATA/dr1ZZZDGPRI.dat' scope = spfile;
System altered.
SYS@dgpri>alter system set dg_broker_config_file2 = '+DATA/dr2ZZZDGPRI.dat' scope = spfile;
System altered.
备库：
SYS@dgphy>alter system set dg_broker_config_file1 = '+DATADG/dr1ZZZDGPHY.dat' scope = spfile;
System altered.
SYS@dgphy>alter system set dg_broker_config_file2 = '+DATADG/dr2ZZZDGPHY.dat' scope = spfile;
System altered.
重启主备库
5、配置DG_BROKER监听和TNS
可以使用默认监听，也可以创建一个非默认监听，这里使用默认监听。
查看domain，如果存在则需要在服务后加上domain后缀
SYS@dgpri>show parameter domain
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_domain string
**配置LISTENER**
主库：
[grid@kkk admin]$ cat listener.ora
#Backup file is /u01/app/grid/crsdata/kkk/output/listener.ora.bak.kkk.grid line added by Agent
# listener.ora Network Configuration File: /u01/app/19.2.0.0.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.16)(PORT = 1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=

(SID_NAME=dgpri)
)
(SID_DESC=
(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)
(GLOBAL_DBNAME=ZZZDGPRI_DGMGRL) #DG_BROKER专用服务名
(SID_NAME=dgpri)
)
)
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
VALID_NODE_CHECKING_REGISTRATION_LISTENER=ON # line added by Agent
备库：
[grid@hhh admin]$ cat listener.ora
#Backup file is /u01/app/grid/crsdata/hhh/output/listener.ora.bak.hhh.grid line added by Agent
# listener.ora Network Configuration File: /u01/app/19.2.0.0.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.17)(PORT = 1521))
)
)
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)
(GLOBAL_DBNAME=ZZZDGPHY)
(SID_NAME=dgphy)
)
(SID_DESC=
(ORACLE_HOME=/u01/app/oracle/product/19.2.0.0.0/dbhome_1)
(GLOBAL_DBNAME=ZZZDGPHY_DGMGRL)
(SID_NAME=dgphy)
)
)
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER=ON # line added by Agent
VALID_NODE_CHECKING_REGISTRATION_LISTENER=ON # line added by Agent
添加后lsnrctl reload
配置TNS
主备库tnsnames.ora文件添加如下
TNS_ZZZDGPRI_DGMGRL=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.16)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ZZZDGPRI_DGMGRL)
)
)
TNS_ZZZDGPHY_DGMGRL=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.59.17)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = ZZZDGPHY_DGMGRL)
)
)
6、配置DG_BROKER参数文件
DGMGRL> create configuration c1 as primary database is ZZZDGPRI connect identifier is TNS_ZZZDGPRI_DGMGRL
> ;
**12c环境直接添加备库会报错，清空log_archive_dest_n**
DGMGRL> add database ZZZDGPHY as connect identifier is TNS_ZZZDGPHY_DGMGRL maintained as PHYSICAL;
Error: ORA-16698: member has a LOG_ARCHIVE_DEST_n parameter with SERVICE attribute set
