Query whether the tablespace is set to augment
After logging in to the database table
Enter select TABLESPACE_NAME, AUTOEXTENSIBLE from dba_data_files
The YES field in AUT indicates that the table space sets the self-increment policy, while the display NO indicates that the table space does not have a self-increment policy.
If you need to modify its self-increment, the command is as follows:
Alter database datafile'+ SZCG_ASM_GROUP/szcg/datafile/tbs_dxpt.dbf' autoextend on next 20m
