oracle 12.2.0.1 搭建 active dataguard
生活随笔
收集整理的這篇文章主要介紹了
oracle 12.2.0.1 搭建 active dataguard
小編覺得挺不錯的,現在分享給大家,幫大家做個參考.
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，后面會記錄 rac + asm 的形式。
任何時候都要說下三種模式：
最大保護：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;

adb-node1 192.168.56.101 master
安裝好了12.2.0.1 的軟件，并創建了數據庫
dataguard 所有節點的 db_name 是相同的，通過db_unique_name來區分彼此。
主庫name相關

安裝好了12.2.0.1 的軟件，不創建數據庫,用duplicate命令從master拉過來
備庫name相關
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。
備庫目錄相關
參考主庫創建必要的目錄
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備庫拷貝master 的password file
