DB2数据库普通用户如何查询表空间大小？

1. 统计所有节点表空间使用率
   　　select substr(TABLESPACE_NAME,1,20) as TBSPC_NAME,bigint(TOTAL_PAGES * PAGE_SIZE)/1024/1024 as "TOTAL(MB)",
   used_pagesPAGE_SIZE/1024/1024 as "USED(MB)", free_pagesPAGE_SIZE/1024/1024 as "FREE(MB)"
   from table(snapshot_tbs_cfg('DB_NAME', -2)) as snapshot_tbs_cfg

2、查看表空间使用率
　　select substr(tbsp_name,1,20) as TABLESPACE_NAME,substr(tbsp_content_type,1,10) as TABLESPACE_TYPE,sum(tbsp_total_size_kb)/1024 as TOTAL_MB,

  sum(tbsp_used_size_kb)/1024 as USED_MB,sum(tbsp_free_size_kb)/1024 as FREE_MB,tbsp_page_size AS PAGE_SIZE 
from SYSIBMADM.TBSP_UTILIZATION group by tbsp_name,tbsp_content_type,tbsp_page_size

　　order by 1
