在primary端pfile参数文件和密码文件，并且拷贝到standby段相应路径
SQL> create pfile='/oracle/backup/pfile0523.ora' from spfile;
scp orapworcl oracle@192.168.56.109:/oracle/backup
scp pfile0523.ora oracle@192.168.56.109:/oracle/backup
backup as compressed backupset full database include current controlfile for standby format '/oracle/backup/db_%T_%s_%p.bak' plus archivelog format '/oracle/backup/archfull_%T_%s_%p.bak';
备库监听设置

设置告警日志文件路径
pfile文件中有记录
*.audit_file_dest='/oracle/app/oracle/admin/orcl/adump'
mkdir -p /oracle/app/oracle/admin/orcl/adump
先关闭再启动

group 6 ('/oracle/app/oracle/orcl/styredo06.log') size 50m,
group 7 ('/oracle/app/oracle/orcl/styredo07.log') size 50m;
查询standby日志组
SELECT GROUP#,THREAD#,SEQUENCE#,ARCHIVED,STATUS FROM V$STANDBY_LOG;
备库开启实时应用
recover managed standby database using current logfile disconnect from session;
查询备库应用日志状态
select process,client_process,sequence#,status from v$managed_standby;
