oracle 12.2.0.1 搭建 active dataguard

os: centos 7.4
database：12.2.0.1 + dbf

本次是以 oracle database 12.2.0.1 + dbf 的形式部署的，后面会记录 rac + asm 的形式。

任何时候都要说下三种模式：

最大保护：maximize protection
最高性能：maximize performance
最高可用：maximize availability

alter database set standby to maximize protection;
alter database set standby to maximize performance;
atler database set standby to maximize availability;

oradb-node1 192.168.56.101 master

adb-node1 192.168.56.101 master
安装好了12.2.0.1 的软件，并创建了数据库
dataguard 所有节点的 db_name 是相同的，通过db_unique_name来区分彼此。

主库name相关

db_name:            orcl
db_unique_name:     orclp
net service name:   tns_orclp

修改 db_unique_name

SQL> alter system set db_unique_name='orclp' scope=spfile;System altered.

修改 net service name

$ vi listener.ora 
SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = orcl)(ORACLE_HOME = /u01/app/oracle/product/12.2.0/db_1)(SID_NAME = rac01)))

$ vi tnsnames.ora
tns_orclp =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = oradb-node1)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))tns_orcls1 =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = oradb-node2)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))

主库启用 force logging

SQL> alter database force logging;Database altered.

主库启用 archivelog

SQL> archive log list;
Database log mode          No Archive Mode
Automatic archival         Disabled
Archive destination        /u01/app/oracle/product/12.2.0/db_1/dbs/arch
Oldest online log sequence     1

SQL> shutdown immediate;
SQL> startup mount;
SQL> alter database archivelog;
SQL> alter database open;

执行 open pdb,确保处于 read write

SQL> show pdbs;CON_ID CON_NAME           OPEN MODE  RESTRICTED
---------- ------------------------------ ---------- ----------2 PDB$SEED              READ ONLY  NO3 RAC01PDB           MOUNTED

---------- ------------------------------ ---------- ----------2 PDB$SEED              READ ONLY  NO3 RAC01PDB           READ WRITE NO

主库创建 standby redo logfile

SQL> select * from v$log;GROUP#    THREAD#  SEQUENCE#      BYTES  BLOCKSIZE    MEMBERS ARC STATUS           FIRST_CHANGE# FIRST_TIME      NEXT_CHANGE# NEXT_TIME           CON_ID

最少添加n+1个standby redo logfile，完全可以比n+1多，如下面

alter database add standby logfile '/u01/app/oracle/oradata/standby_redo01.log' size 200M;
alter database add standby logfile '/u01/app/oracle/oradata/standby_redo02.log' size 200M;
alter database add standby logfile '/u01/app/oracle/oradata/standby_redo03.log' size 200M;
alter database add standby logfile '/u01/app/oracle/oradata/standby_redo04.log' size 200M;
alter database add standby logfile '/u01/app/oracle/oradata/standby_redo05.log' size 200M;

主库创建 pfile,并修改

oradb-node2 192.168.56.102 physical standby

安装好了12.2.0.1 的软件，不创建数据库,用duplicate命令从master拉过来

备库name相关

db_name:            orcl
db_unique_name:     orcls1
net service name:   tns_orcls1

修改 net service name

$ vi listener.ora 
SID_LIST_LISTENER =(SID_LIST =(SID_DESC =(GLOBAL_DBNAME = orcl)(ORACLE_HOME = /u01/app/oracle/product/12.2.0/db_1)(SID_NAME = rac01)))

$ vi tnsnames.ora
tns_orclp =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = oradb-node1)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))tns_orcls1 =(DESCRIPTION =(ADDRESS = (PROTOCOL = TCP)(HOST = oradb-node2)(PORT = 1521))(CONNECT_DATA =(SERVER = DEDICATED)(SERVICE_NAME = orcl)))

上面的 listener.ora、tnsnames.ora 需要和master 保持一致。

备库目录相关

参考主库创建必要的目录

mkdir -p $ORACLE_BASE/admin/orcl/adump
mkdir -p $ORACLE_BASE/archivelog
mkdir -p $ORACLE_BASE/audit
mkdir -p $ORACLE_BASE/oradata/orcl
mkdir -p $ORACLE_BASE/oradata/pdbseed
mkdir -p $ORACLE_BASE/oradata/rac01pdb

备库拷贝master 的password file

$scp ./orapwrac01 oracle@192.168.56.102:/u01/app/oracle/product/12.2.0/db_1/dbs

备库spfile内容如下

备库开始active duplicate

$ rman target sys/oracleoracle@tns_orclp  auxiliary sys/oracleoracle@tns_orcls1RMAN> duplicate target database for standby from active database nofilenamecheck dorecover;

备库打开

此时查看pdb

备库开始real-time apply

SQL> alter database recover managed standby database using current logfile disconnect from session;

验证

备库查看日志

$ tail -f -n 1000 /u01/app/oracle/diag/rdbms/orcls1/rac01/trace/alert_rac01.log

主库查看

selectdbms_flashback.get_system_change_number() as master_current_scn,ad.APPLIED_SCN,ad.*
from v$archive_dest ad
where 1=1
;select *
from v$archive_dest_status
;select *
from v$archive_gap
;select *
from v$archive_processes
;

整体来说和11g手动搭建dataguard基本类似，需要注意的是记得操作pdb
