--尽量少用触发器,否则数据库增长很快,特别是关于登陆的数据表字段不要用出发器,一周左右能使得数据库增长1G的空间. --数据库表空间大小查询脚本 IF EXISTS (SELECT * FROM sys.objects WHERE object_id = OBJECT_ID(N'[dbo].[#Data]') AND type in (N'U'))DROP TABLE [dbo].[#Data] create table #Data(name varchar(100),row varchar
dba_data_files:数据库数据文件信息表.可以统计表空间大小(总空间大小). dba_free_space:可以统计剩余表空间大小. 增加表空间即向表空间增加数据文件,表空间大小就是数据文件总大小. 检查Oracle各个表空间的增长情况(各表空间使用率) select A.tablespace_name,(1-(A.total)/B.total)*100 used_percent from (select tablespace_name,sum(bytes) total from db

默认DB2 缓冲池信息监控是OFF, 需要开启(DB2表空间是由缓冲池分配的) CollBufferpool : ============ The CollBufferpool collector collects information for the DB2UDB_BUFFERPOOL application class and provides the values for monitoring DB2 buffer pools. Note: For the CollBufferpool

System表空间大小有10Gb,使用率达到95%,很好奇, 随后执行如下SQL,查看system表空间中使用空间最多的对象 SQL>SELECT * FROM DBA_SEGMENTS T WHERE t.tablespace_name='SYSTEM' ORDER BY T.BYTES desc; 发现sys.aud$及其索引共计占用7.9Gb, 大家应该知道,11g默认开启了审计功能,所以才导致审计表占用了system大量的空间,如果对审计数据没有特殊需求可根据实际情况来解决: 临时解决
