Drop table releases the space occupied by the segment, while the OS space occupied by Data Files remains unchanged.

Therefore, the efficiency can be simplified to the following formula:
tbs= size of the transfer block (table 7.1.7.2.1-1)
crc= the number of bits that are attached for error checking =24
There are two reasons why Oracle table space is low:1. The original table space is too small, no self-growth;2. Table space has grown and table space is large enoughCheck Cause:1. View the table in that table spaceSelectTablespace_name,table_name fromUser_talbeswhereTable_name='Test';2. Get the default tablespace for a userSelectUsername, Default_tablespace fromDba_userswhereUsername='Mxh';3. View all the files in the tablespaceSelect* fromDba_data_fileswhereTablespace_name='USERS';4. View table

The following two modifications are the same

Or. The reason is that user A has the following system permissions:

PRIVILEGE
---------------------
UNLIMITED TABLESPACE
Unlimited tablespace indicates that there is no limit to the use of table space. Therefore, you can create A table in any TABLESPACE. The reason why user A has this system permission is that the operation of the resource role is granted. For more information, see the previous article:

The disk of the Oracle installation directory is fully stretched, causing the Oracle database to hang, querying the Internet for a solution that is divided into two ways:
One, mobile table space files
1, modify the table space offline state
ALTER tablespace ts_partition_000 OFFLINE;
2, copy the table space corresponding file to a new location
cp/opt/oracle/11g/dbs/ts_partition_000/oradata/dtcdb/tbs/ts_partition_000
3, modify the table space data
