1. 检查当前主备库同步状态 on primary select ads.dest_id,max(sequence#) "Current Sequence", max(log_sequence) "Last Archived" from v$archived_log al, v$archive_dest ad, v$archive_dest_status ads where ad.dest_id=al.dest_id and al.dest_id=ads.dest_

1. primary库设置dataguard相关参数 1.1. 强制primay库在任何状态下必须记录日志 SYS@userdata>select FORCE_LOGGING from v$database; FORCE_LOG --------- NO SYS@userdata>alter database force logging; Database altered. SYS@userdata>select FORCE_LOGGING from v$database; FORCE_

1. 检查主备库的状态 on primary column DATABASE_ROLE format a20 column OPEN_MODE format a15 column PROTECTION_MODE format a20 column SWITCHOVER_STATUS format a20 select DATABASE_ROLE,OPEN_MODE,PROTECTION_MODE,SWITCHOVER_STATUS from v$database; DATABASE_ROLE O

1. dataguard主备切换 1.1. 查看当前主备库是否具备切换条件 on slave select sequence#,first_time,next_time,archived,applied from v$archived_log where SEQUENCE#=(select max(SEQUENCE#) from v$archived_log); SEQUENCE# FIRST_TIME NEXT_TIME ARCHIVED APPLIED ---------- --------
