Oracle 查看表空间及扩容

首先查看所有表空间的大小：

SELECT T.TABLESPACE_NAME, ROUND(SUM(BYTES/(1024 * 1024)), 0) TS_SIZE FROM DBA_TABLESPACES T, DBA_DATA_FILES D WHERE T.TABLESPACE_NAME = D.TABLESPACE_NAME GROUP BY T.TABLESPACE_NAME;

查看空间路径、空间名，最大空间、易用空间

select FILE_NAME, TABLESPACE_NAME, MAXBYTES/1024/1024 maxsizes, USER_BYTES/1024/1024 userbytes from dba_data_files

查看OMSFM库下的所有表

select owner,table_name from all_tables WHERE OWNER = \'OMSFM\'

增加表空间：

ALTER DATABASE DATAFILE \'/opt/oracle/oradata/TEST/test.dbf\' RESIZE 2000M;
