To check the tablespace usage in an Oracle database, you can query the DBA_TABLESPACES view. Here is an example SQL query that will show the usage of each tablespace in the database: SELECT tablespace_name, ROUND((1 - (free_space / total_space)) * 100, 2) AS used_percent FROM (SE...
where t.tablespace_name = f.tablespace.name and t.tablespace_name in ('XXXXTablespaceName‘) order by t.tablespace_name;
group by tablespace_name) b where a.tablespace_name = b.tablespace_name order by ((a.bytes - b.bytes) / a.bytes) desc
Hello Guys, I am using the query bellow to check the usage of tablespaces in my oracle DBs: select t.tablespace_name, t.size_mb, f.free_mb, round((f.free_mb*100)/t.size_mb,2) percent_free from (select tablespace_name, round(sum(bytes)/1024/1024,2) size_mb from dba_data_files...
官方文档对于DBA_TABLESPACE_USAGE_METRICS的技术是:DBA_TABLESPACE_USAGE_METRICS describes tablespace usage metrics for all types of tablespaces, including permanent, temporary, and undo tablespaces.翻译过来是:DBA_TABLESPACE_USAGE_METRICS 描述了所有类型表空间的表空间使用指标...
官网对v$filespace_usage 视图的说明如下: V$FILESPACE_USAGE summarizes spaceallocation information of each datafile and tempfile. 根据以上的分析,我们可以得出一个结论: 1. DBA_TABLESPACE_USAGE_METRICS的USED_SPACE是已经分配的空间,对应V$FILESPACE_USAGE的ALLOCATED_SPACE的字段。
Check Tablespace Growth in Oracle To get a tablespace’s growth, we can query the data dictionary view DBA_HIST_TBSPC_SPACE_USAGE, which holds the historical usage of a tablespace to predict future growth. See the oracle reference for this table fromhere. It’s available in AWR or Automatic...
1、Tablespace IO Stats 表空间的I/O性能统计。 Reads 发生了多少次物理读。 Av Reads/s 每秒钟物理读的次数。 Av Rd(ms) 平均一次物理读的时间(毫秒)。一个高相应的磁盘的响应时间应当在10ms以内,最好不要超过20ms;如果达到了100ms,应用基本就开始出现严重问题甚至不能正常运行。
DBA_TABLESPACE_USAGE_METRICSdescribestablespace usage metrics for all types of tablespaces, including permanent,temporary, and undo tablespaces. 从官网的说明,这个视图很方便,通过DBA_TABLESPACE_USAGE_METRICS视图就可以查看所有类型表空间的使用情况,包括永久,临时和undo 表空间。
