搭建windows到linux的oracle 12c physical standby备库

千家信息网最后更新 2025年01月22日搭建windows到linux的oracle 12c physical standby备库primary上修改参数

ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl,orcldg)';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=orcldg NOAFFIRM ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcldg';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;
ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=30;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;
ALTER SYSTEM SET FAL_SERVER=orcl;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;
alter system set db_file_name_convert='/u01/app/oracle/oradata/orcl','E:\APP\ADMINISTRATOR\ORADATA\ORCL' scope=spfile;
alter system set log_file_name_convert='/u01/app/oracle/oradata/orcl','E:\APP\ADMINISTRATOR\ORADATA\ORCL\' scope=spfile;

主库上创建standby logfile group
SQL> alter database add standby logfile group 4 ('E:\APP\ADMINISTRATOR\ORADATA\O
RCL\REDO04.LOG') SIZE 50M;


数据库已更改。


SQL> alter database add standby logfile group 5 ('E:\APP\ADMINISTRATOR\ORADATA\O
RCL\STBY_REDO05.LOG') SIZE 50M;


数据库已更改。


SQL> alter database add standby logfile group 6 ('E:\APP\ADMINISTRATOR\ORADATA\O
RCL\STBY_REDO06.LOG') SIZE 50M;


数据库已更改。


SQL> ALTER DATABASE DROP LOGFILE GROUP 4;


数据库已更改。


SQL> alter database add standby logfile group 4 ('E:\APP\ADMINISTRATOR\ORADATA\O
RCL\STBY_REDO04.LOG') SIZE 50M;


在primary上创建控制文件，并拷贝至linux服务器的参数文件所对应的目录

备库pfile参数文件， 注意linux下的几个目录预先创建好:

恢复脚本：

run
{
set newname for datafile 1 to '/u01/app/oracle/oradata/orcl/SYSTEM01.DBF';
set newname for datafile 3 to '/u01/app/oracle/oradata/orcl/SYSAUX01.DBF';
set newname for datafile 5 to '/u01/app/oracle/oradata/orcl/UNDOTBS01.DBF';
set newname for datafile 6 to '/u01/app/oracle/oradata/orcl/USERS01.DBF';
restore database;
switch datafile all;
recover database;
}
