操作命令：
SQL>?alter?tablespace?users?offline;
Tablespace?altered.
SQL>?alter?tablespace?users?online;
Tablespace?altered.
将表空间置为只读模式和读写模式：
SQL>?alter?tablespace?users?read?only;
Tablespace?altered.
SQL>?alter?tablespace?users?read?write;
Tablespace?altered.
删除表空间：
SQL>?drop?tablespace?users?including?contents?and?datafiles;
Tablespace?dropped.
