安装数据库

  1. 主库RAC已经存在

  2. 备库安装数据库软件和创建监听即可，这里备库使用docker容器，然后使用以下方式删除现有数据库：

确认主库信息

参见主RAC信息收集

配置主库参数

在配置RAC主库基础上进行如下修改：

修改主库以下dg参数：

1
2
3
4
5
6
7
8
9
10
11
-- dg参数
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(racdb_primary,racdb_standby1,racdb_standby2)' SCOPE=BOTH SID='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_3='SERVICE=racdb_standby2 LGWR SYNC REOPEN=15 VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=racdb_standby2' SCOPE=BOTH SID='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_3=enable SCOPE=BOTH SID='*';
-- 以上参数无需重启

-- Add below item when DB turn to standby role
-- 因主库使用ASM，此备库为单机，因此如果需要主RAC和此备库进行互切，则配置转换参数，否则主库无需配置，此参数需要重启生效
-- alter system set db_file_name_convert='+DATA/primary','+DATA/standby'  scope=spfile;
-- alter system set log_file_name_convert='+DATA/primary','+DATA/primary'  scope=spfile;
ALTER SYSTEM SET FAL_SERVER='racdb_standby1,racdb_standby2' SCOPE=BOTH SID='*';
