要调整Oracle表空间的大小,可以按照以下步骤操作:
SELECT tablespace_name FROM dba_tablespaces;
SELECT tablespace_name, SUM(bytes)/1024/1024 AS "Total(MB)", SUM(bytes)/1024/1024 - SUM(used_bytes)/1024/1024 AS "Free(MB)", SUM(used_bytes)/1024/1024 AS "Used(MB)" FROM dba_free_space WHERE tablespace_name = 'your_tablespace_name' GROUP BY tablespace_name;
ALTER TABLESPACE your_tablespace_name RESIZE 100M; --将表空间大小调整为100MB
SELECT tablespace_name, SUM(bytes)/1024/1024 AS "Total(MB)", SUM(bytes)/1024/1024 - SUM(used_bytes)/1024/1024 AS "Free(MB)", SUM(used_bytes)/1024/1024 AS "Used(MB)" FROM dba_free_space WHERE tablespace_name = 'your_tablespace_name' GROUP BY tablespace_name;
注意:在调整表空间大小之前,请确保有足够的磁盘空间可用,并且谨慎操作以避免数据丢失或数据库不可用的情况发生。
