前言

是否你也长期饱受数据库服务器文件系统使用率告警的困扰？是否时常因 Oracle adump 审计日志疯狂堆积，引发 inode 耗尽、数据库异常卡顿的问题？又或是监听日志持续膨胀，最终导致监听无法正常工作、业务断连而束手无策？

日常手动清理日志不仅操作繁琐、耗时长，误删核心文件还存在极高数据库运行风险。为此，一款适配 Linux 环境的日志清理工具应运而生 —— purgelogs 命令工具，它专为 Oracle 数据库各类冗余文件设计，能够安全、高效清理审计日志、监听日志、各类监控垃圾日志，从根源解决磁盘占满、inode 耗尽、监听失效等一系列运维难题，充分体现了使用该工具清理 Oracle 垃圾文件的必要性、安全性与高效快捷性。

官方推荐清理工具 purgelogs

一键自动化归档并清理由 Oracle Grid Infrastructure、RDBMS、TFA、OSWatcher、OAK 和 DCS 在一体机 Exadata、ODA、DS、ExaCS 和 ExaC@C 上生成的跟踪信息和日志。

purgelogs 在数据库主机本身上运行。它会自动发现您的 Oracle 主目录，遍历正确的 ADR/TFA/OSWatcher/OAK/DCS 路径，然后删除旧的跟踪文件和日志，或将它们存档到本地文件系统路径，或直接存档到OCI对象存储桶中。

每个组件的默认保留期为 30 天，purgelogs 被设计为在所有集群节点上运行（通常作为 cron 作业）。

-----------------------------------------------------------------------
Above warning 'DIA-49803' could be solved executing following command:
/opt/purgelogs/out/shell/migrate_schema_15175.sh
-----------------------------------------------------------------------

还可以指定具体目录，清理对应目录下的文件，清理来自某些指定“额外”文件夹（如/tmp、/var/log、/opt/app）的文件/痕迹/核心数据等，并设定不同的保留期限。比如：

/opt/purgelogs/purgelogs.bin cleanup --extra '/tmp':10,'/var/log':20,'/opt/app':30

清理 OSWatcher/ExaWatcher 存档文件和 OAK 日志，删除所有超过 35 天的文件。

/opt/purgelogs/purgelogs.bin cleanup --osw 35 --oda 35

清理监听日志,使用 ‘-lsnr’ 选项，purgelogs 将强制按时间独立清理监听器日志。

/opt/purgelogs/purgelogs.bin cleanup --orcl 50 --lsnr

将 purgeLogs 设置为 crontab 作业

例如，我们正在设置 purgleogs 任务，每天凌晨 2 点执行一次，清除超过 30天的 GI/RDBMS 跟踪日志，并保留不超过 10 天的TFA、OSWatcher 和 ODA 日志。

00 02 * * * /opt/purgelogs/purgelogs.bin cleanup --orcl 30 --tfa 10 --osw 10 --oda 10

注意事项：

1、使用 root 用户安装和执行，或者配置 sudo 权限。
2、不能清理归档日志，不管是 ASM 或者文件系统中的归档日志，均不能清理。
3、对于单机没有 GI 的数据库，必须配置 /etc/oratab 文件。
4、如果你的环境是 Oracle RAC 环境，那么可以配置 tfactl set manageLogsAutoPurge=ON 来清理日志。

# TFA 关闭自动清理，默认清理 30 天前的各种日志
tfactl set manageLogsAutoPurge=OFF

# 查看自动清理开关和保留天数
tfactl print config | grep -i purge

# 查看 TFA 自动清理历史记录
tfactl print purgelog

# 修改日志仅保留7天
tfactl set manageLogsAutoPurgeAge=7

# 手动立即执行一次全量日志清理（不依赖定时任务）
tfactl purge

purgelog 新版本还可以支持更多功能，更多使用方法和细节，请参考 MOS 官方说明。
