Oracle Daily Check 4
检查Oracle相关资源的使用情况
1
sql> select resource_name,max_utilization, initial_allocation, limit_value
from v$resource_limit ;
若“LIMIT_VALU”-“MAX_UTILIZATION”<=5,
则表明与“RESOURCE_NAME”相关的Oracle初始化参数需要调整。
可以通过修改Oracle初始化参数文件
$ORACLE_BASE/admin/ORCL/pfile/initORCL.ora来修改。
2 检查Oracle各个表空间的增长情况
select A.t ablespa ce_nam e,(1-(A .total )/B.tot al)*10 0 used_ percen t
f r om
(se lect ta blespa ce_name ,sum(b ytes) t otal
fro m dba_f ree_sp ace gro up by tablesp ace_na me) A,
(se lect ta blespa ce_name ,sum(b ytes) t otal
fro m dba_d ata_fi les gro up by tablesp ace_na me) B
whe re A.ta blespa ce_name =B.tab lespace _name;
