Introduction
The Oracle ORA-01628 error is a common error that occurs when trying to extend a tablespace, but the datafile is already at its maximum size. This error can be caused by a variety of issues related to the storage and management of datafiles within the Oracle database system.
Causes
Cause 1: Datafile Already at Maximum Size
When trying to extend a tablespace, the datafile may already be at its maximum size, causing the ORA-01628 error to occur.
ALTER DATABASE DATAFILE '/path/to/datafile.dbf' AUTOEXTEND ON MAXSIZE 100M;
Solution
To resolve this issue, you can either add a new datafile to the tablespace or increase the maximum size of the existing datafile.
ALTER TABLESPACE example_ts ADD DATAFILE '/new/path/to/new_datafile.dbf' SIZE 100M;
Detailed Solutions
To prevent this issue from occurring in the future, you can regularly monitor the size of your datafiles and proactively add new datafiles or increase the maximum size of existing datafiles as needed. Additionally, you can implement a storage management strategy to ensure that datafiles do not reach their maximum size.
Commonly Faced Issues
One commonly faced issue related to the ORA-01628 error is the lack of available disk space for adding new datafiles or increasing the size of existing datafiles. To address this issue, you can monitor disk space usage and allocate additional disk space as needed.

A: The maximum size of a datafile in Oracle is determined by the operating system and file system limitations. It is important to regularly monitor the size of datafiles and allocate additional space as needed to prevent the ORA-01628 error.
Q: Can I autoextend a datafile beyond its maximum size?
A: No, you cannot autoextend a datafile beyond its maximum size. If the datafile reaches its maximum size, you will need to add a new datafile or increase the maximum size of the existing datafile to resolve the ORA-01628 error.
