ORACLE 数据库系统维护检查报告
注：红色字体表示需要尽快解决的问题。

其它检查内容：
1、alert文件：
有无错误？
2、表空间使用情况：
set linesize 300
SELECT upper(f.tablespace_name) "tablespace_name",
d.Tot_grootte_Mb "tablespace(M)",
d.Tot_grootte_Mb - f.total_bytes "used(M)",
round((d.Tot_grootte_Mb - f.total_bytes) / d.Tot_grootte_Mb * 100,2) "use%",
f.total_bytes "free_space(M)",
round(f.total_bytes / d.Tot_grootte_Mb * 100,2) "free%"
FROM
(SELECT tablespace_name,
round(SUM(bytes)/(1024*1024),2) total_bytes,
round(MAX(bytes)/(1024*1024),2) max_bytes
FROM sys.dba_free_space
GROUP BY tablespace_name) f,
(SELECT dd.tablespace_name, round(SUM(dd.bytes)/(1024*1024),2) Tot_grootte_Mb
FROM sys.dba_data_files dd
GROUP BY dd.tablespace_name) d
WHERE d.tablespace_name = f.tablespace_name
ORDER BY 4 DESC
/
3、Shared Pool Size 命中率：
select round((sum(gets)-sum(reloads))/sum(gets)*100,1) "libiary cache hit ratio %"
from v$librarycache where namespace
in ('SQL AREA','TABLE/PROCEDURE','BODY','TRIGGER');
4、数据字典命中率：
select round((1-sum(getmisses)/sum(gets))*100,1) "data dictionary hit ratio %"
from v$rowcache;
5、锁竞争：
select substr(,1,25) Name,
l.gets, l.misses,
100*(l.misses/l.gets) "% Ratio (STAY UNDER 1%)"
from v$latch l, v$latchname ln
where in ('cache buffers lru chain')
and tch# = tch#;
6、排序命中率：
select a.value "Sort(Disk)", b.value "Sort(Memory)",
round(100*(a.value/decode((a.value+b.value), 0,1,(a.value+b.value))),2) "% Ratio (STAY UNDER 5%)"
from v$sysstat a, v$sysstat b
where = 'sorts (disk)'
and = 'sorts (memory)';
7、数据缓冲区命中率：
select round((1-(phy.value/(cur.value+con.value)))*100,1)||'%' ratio
from v$sysstat phy,v$sysstat cur,v$sysstat con
where ='physical reads' and ='db block gets' and ='consistent gets';
8、v$session_wait：
select sid,seq#,event,WAIT_TIME,SECONDS_IN_WAIT from v$session_wait where event not like 'SQL%' and event not like 'rdbms%';
9、回滚段的争用情况：
select name, waits, gets, waits/gets "Ratio"
from v$rollstat a, v$rollname b
where n = n;
10、无效对象情况：
col OBJECT_NAME for a36
SELECT object_name, object_type,status FROM dba_objects WHERE status like 'INVALID';
