保持 Oracle 数据库的良好健康状况对于系统的可靠性和性能至关重要。本文将介绍一些常用的 Oracle 日常健康脚本,帮助您监控数据库并及时识别潜在的问题,以保证数据库的稳定运行。
1.查询数据库实例和实例级别的信息
通过 gv
d
a
t
a
b
a
s
e
、
g
v
database、 gv
database、gvinstance
查询数据库实例和实例级别的信息。
获取数据库名称、实例名称、平台名称、主机名称、数据库版本和启动时间等信息。
SELECT a.NAME DBNAME,
b.instance_name,
a.PLATFORM_NAME,
b.host_name,
b.version,
b.startup_time
FROM gV$DATABASE a, gv$instance b
where a.inst_id = b.inst_id
order by 2;
2.查询数据库注册表历史记录的详细信息
包括操作时间、动作和注释。通过按照时间降序排序,可以查看最近执行的注册表更改操作和对应的注释。
SELECT TO_CHAR(ACTION_TIME, 'YYYY-MM-DD HH24:MI:SS') ACTION_TIME,
ACTION,
COMMENTS
FROM SYS.DBA_REGISTRY_HISTORY
ORDER BY 1 DESC;
3.查询从V$LOG_HISTORY表中检索最近10天的日志记录
按照日期和小时统计每个小时的日志数量。查询结果按日期和小时排序。
查询使用了SUBSTR函数来提取日期和小时部分,并通过TO_CHAR函数格式化为’MM/DD/RR HH24:MI:SS’的形式。然后使用DECODE函数根据小时值进行条件判断,如果符合条件则返回1,否则返回0。使用SUM函数对每个小时的返回值进行求和,得到每个小时的日志数量。最后使用COUNT函数统计总日志数量。
SELECT SUBSTR(TO_CHAR(FIRST_TIME, 'MM/DD/RR HH:MI:SS'), 1, 5) DAY,
SUM(DECODE(SUBSTR(TO_CHAR(FIRST_TIME, 'MM/DD/RR HH24:MI:SS'), 10, 2),

LOG_ARCHIVE_START:日志归档是否启用的标志,根据LOG_MODE进行解码。如果LOG_MODE是’ARCHIVELOG’,则显示为’ENABLED’;如果LOG_MODE是’NOARCHIVELOG’,则显示为’DISABLED’。
CURRENT_LOG_SEQ:当前日志的序列号,从VKaTeX parse error: Expected 'EOF', got '#' at position 35: …’的日志条目的SEQUENCE#?进行获取。 OLDEST_ON…LOG视图中选择SEQUENCE#的最小值作为最旧的在线日志的序列号。
通过执行这个查询,可以获取数据库的日志模式、日志归档是否启用、当前日志的序列号以及最旧的在线日志的序列号。这些信息对于管理和监控数据库日志非常有用。
