在noarchive模式下不能做alter tablespace XXX begin backup,联机备份只能在数据库位于archivelog模式中才能进行 在noarchive模式下,执行如下,会出现如图所示
本文对此给出了单独还原归档日志以及恢复归档日志的示例以及restore archivelog的一些用法,仅仅是为了更好来的理解还原与恢复的过程,因为大多数情形下,数据文件被还原到缺省路径。...如果是还原到非缺省路径,那就需要手动restore archivelog。...的其它用法 restore archivelog all; 还原全部归档日志文件 restore archivelog from logseq 27 ; 还原log sequence...restore archivelog from time 'sysdate-7'; 还原七天以内的归档日志 restore archivelog until logseq 29; 还原到seqence...set archivelog destination to '/u01/database/sybo5/arch'; restore archivelog low logseq 27;}
最近在因归档日志暴增,使用delete archivelog all貌似无法清除所有的归档日志,到底是什么原因呢?...connected to target database: GOBO4 (DBID=921286879) #下面通过使用rman backup archivelog方式来删除所有的归档日志文件 RMAN...> backup format '/install_source/rman_bak/arch_%d_%U' 2> archivelog all delete input; Starting backup...#再次删除日志文件,来个更狠的命令,直接delete所有的archivelog,最近新增的一个archivelog被删除 RMAN> delete noprompt archivelog all; released...all (RMAN> backup archivelog all delete input;)
这里面就要使用 pg_archivecleanup 这个命令了,可以定时的来运行它,将已经移动到archivecleanup 的目录的archivelog 根据要求开始清理。...当然我们先的说说如果不定期清理会出什么问题 1 如果不定期清理archive 如果存放archivelog 的位置无法在接受新的日志,则大量WAL日志会滞留在 wal_log 目录中,则整体数据库系统都会受到影响...2 占用大量的存储空间,存储无效的数据 那一般来说如果没有第三方的备份工具的情况下,怎么来通过pg_archivecleanup 来进行archivelog 的清理。
