简介: Oracle查询归档日志的产生情况

归档日志大小(通用)

无论归档日志放在文件系统还是ASM磁盘上,都可以通过如下方式查询:

-- 按照天数计算
SELECT to_char(FIRST_TIME,'YYYY-MM-DD') MD,
        ROUND(SUM(a.BLOCKS * a.BLOCK_SIZE) / 1024 / 1024/ 1024) LOGsize_G
FROM v$archived_log a
WHERE a.STANDBY_DEST='NO'  AND  a.FIRST_TIME >= SYSDATE - 30
-- and a.name is not null
group by to_char(FIRST_TIME,'YYYY-MM-DD')
order by to_char(FIRST_TIME,'YYYY-MM-DD');



-- 计算总大小
SELECT  ROUND(SUM(a.BLOCKS * a.BLOCK_SIZE) / 1024 / 1024/ 1024) LOGsize_G
FROM v$archived_log a
WHERE a.STANDBY_DEST='NO'  AND  a.FIRST_TIME >= SYSDATE - 30
-- and a.name is not null
order by to_char(FIRST_TIME,'YYYY-MM-DD');

归档日志存放在在文件系统

在文件系统上,进入归档目录后,可以直接用如下命令查询:

du -sh ./*

【YashanDB 知识库】通过 dblink 查询 Oracle 数据时报 YAS-07301 异常
客户在使用 YashanDB 通过 yasql 查询 Oracle 数据时,遇到 `YAS-07301 external module timeout` 异常,导致 dblink 功能无法正常使用,影响所有 YashanDB 版本。原因是操作系统资源紧张,无法 fork 新子进程。解决方法包括释放内存、停掉不必要的进程或增大进程数上限。分析发现异常源于 system() 函数调用失败,返回 -1,通常是因为 fork() 失败。未来 YashanDB 将优化日志信息以更好地诊断类似问题。

【赵渝强老师】Oracle的闪回事务查询
Oracle数据库的闪回事务查询(Flashback Transaction Query)是闪回版本查询的扩充,可用于审计或撤销已提交的事务。通过`flashback_transaction_query`视图,可生成还原特定事务的SQL语句。本文介绍了其基本概念,并通过实战演示如何使用该功能:从授权、开启UNDO数据增强,到创建测试表和事务,最后利用闪回查询撤销已提交的事务,验证数据恢复效果。附带视频讲解,帮助深入理解。

【YashanDB知识库】设置归档日志上限,但归档日志没自动清理,导致磁盘空间满
客户在一主一备性能压测中设置了归档日志清理上下限(12G-16G),但实际产生了100G+归档日志,导致磁盘空间满。原因是未设置ARCH_CLEAN_IGNORE_MODE=BACKUP,系统默认在备份后才清理日志。解决方法是设置ARCH_CLEAN_IGNORE_MODE=BACKUP,并执行`alter database delete archivelog all`触发清理。修改参数后,日志仍可能短暂超过上限,因备机同步延迟。经验总结:需同时设置归档上下限和ARCH_CLEAN_IGNORE_MODE=BACKUP以确保日志及时清理。

YashanDB归档日志文件管理
本文介绍了YashanDB中归档日志文件的管理,包括默认存储路径($YASDB_DATA/archive)和文件命名规则。单机部署格式为arch_{resetlogs_id}_{sequence}.ARC,共享集群新增instanceId字段,格式为arch{instanceId}_{resetlogs_id}_{sequence}.ARC。1号节点与单机格式一致。可通过V$ARCHIVED_LOG视图查询相关信息,文件的增删由归档管理操作控制,详情参见官方文档。
