oracle19c rac 本地搭建adg
注意点：
本地搭建和异地搭建，主要需注意pdb的访问问题，本地需要将备库绑定到不同端口的监听，避免无法连接pdb（关键第4步）
（也可以不修改端口，修改tnsnames.ora指定实例即可，参看https://blog.csdn.net/jycjyc/article/details/107738737）
1.启用归档：

主备配置归档删除策略，避免归档未应用被删除的情况：
CONFIGURE ARCHIVELOG DELETION POLICY TO APPLIED ON ALL STANDBY;
2.增加standby_log

3.主库添加db_unique_name
SQL> alter system set db_unique_name='orcl' scope=spfile sid='*';
4.创建监听DGLISTENER，端口2521
grid用户通过图形netca创建DGLISTENER，方便自动添加资源到集群中管理。
增加scan listener端口：srvctl modify scan_listener -endpoints "TCP:1521/TCP:2521"
节点rac1添加如下静态监听参数：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = orcl1)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl_DGMGRL)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = orcl1)
)
)
SID_LIST_DGLISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = dgorcl)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = dgorcl1)
)
(SID_DESC =
(GLOBAL_DBNAME = dgorcl_DGMGRL)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = dgorcl1)
)
)
节点rac2添加如下静态监听参数：
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = orcl)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = orcl2)
)
(SID_DESC =
(GLOBAL_DBNAME = orcl_DGMGRL)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = orcl2)
)
)
SID_LIST_DGLISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = dgorcl)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = dgorcl2)
)
(SID_DESC =
(GLOBAL_DBNAME = dgorcl_DGMGRL)
(ORACLE_HOME = /oracle/app/oracle/product/19c/dbhome_1)
(SID_NAME = dgorcl2)
)
)
5.创建tnsnames.ora内容
[oracle@rac1 admin]$ cat tnsnames.ora
# tnsnames.ora Network Configuration File: /oracle/app/oracle/product/19c/dbhome_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

(CONNECT_DATA =
(SERVER = DEDICATED)

)
6.修改local_listener和remote_listener内容
节点1：
export ORACLE_SID=orcl1
sqlplus / as sysdba
alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.183)(PORT=1521))' scope=both sid='orcl1';
alter system set remote_listener ='rac-scan:1521' scope=both sid='orcl1';
export ORACLE_SID=dgorcl1
sqlplus / as sysdba
alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.183)(PORT=2521))' scope=both sid='dgorcl1';
alter system set remote_listener ='rac-scan:2521' scope=both sid='dgorcl1';
节点2：
export ORACLE_SID=orcl2
sqlplus / as sysdba
alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.184)(PORT=1521))' scope=both sid='orcl2';
alter system set remote_listener ='rac-scan:1521' scope=both sid='orcl2';
export ORACLE_SID=dgorcl2
sqlplus / as sysdba
alter system set local_listener ='(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.52.184)(PORT=2521))' scope=both sid='dgorcl2';
alter system set remote_listener ='rac-scan:2521' scope=both sid='dgorcl2';
7.dbca创建备库dgorcl
dbca -silent -createDuplicateDB \
-gdbName orcl \
-sid dgorcl \
-sysPassword oracle \
-primaryDBConnectionString 192.168.52.183:1521/orcl \

8.添加主备参数:
---创建路径

主库修改参数：
show parameter dg
alter system set dg_broker_config_file1='+DATA/dgshare/dr1orcl.dat' SID='*';
