几年前Oracle 发布了 hcheck.sql 脚本文档 ID 136697.1来检查数据库中已知的数据字典问题。 DBMS_HCHECK 包意味着我们不再需要下载 hcheck.sql 脚本来执行此操作。需要 hcheck.sql 脚本可以留言。
存储过程中的参数FULL 程序进行详尽的检查而 CRITICAL 选项仅专注于最基本的检查使其执行速度更快。这些过程最有价值的方面之一是它们不仅能够识别问题而且还能够修复问题如果您设置了 Repair TRUE 参数。
关于结果的说明
执行结果报告如下
CRITICAL需要立即关注并修复。
FAIL需要解决的高优先级问题。
WARN不紧急但值得解决。
PASS未检测到问题。
注意在 Oracle 23c 中此包称为 DBMS_HCHECK而在早期版本如 Oracle 23.3ai中它称为 DBMS_DICTIONARY_CHECK。 以下实验环境为Oracle 23ai采用的DBMS_DICTIONARY_CHECK。
一、使用脚本检查数据字典
1.1 检查cdb
