【赵渝强老师】Oracle的参数文件与告警日志文件
本文介绍了Oracle数据库的参数文件和告警日志文件。参数文件分为初始化参数文件（PFile）和服务器端参数文件（SPFile），在数据库启动时读取并分配资源。告警日志文件记录了数据库的重要活动、错误和警告信息，帮助诊断问题。文中还提供了相关视频讲解和示例代码。

探索 Linux 命令 `db_archive`：Oracle 数据库归档日志的工具
探索 Linux 中的 `db_archive`，实际与 Oracle 数据库归档日志管理相关。在 Oracle 中，归档日志用于恢复，当在线重做日志满时自动归档。管理员可使用 SQL*Plus 查看归档模式，通过 `RMAN` 进行备份和恢复操作。管理归档日志需谨慎，避免数据丢失。了解归档管理对 Oracle 管理员至关重要，确保故障时能快速恢复数据库。
