If you encounter the ORA-01228 error in Oracle, it means that there is an invalid quota specification for a tablespace. This error can occur when attempting to create or alter a user, tablespace, or data file. To diagnose and fix this issue, follow the steps below.
Diagnosing the ORA-01228 Error
When you encounter the ORA-01228 error, Oracle will provide additional information about the specific quota that is causing the issue. To diagnose the error, you can use the following query to identify the invalid quota specification:
SELECT * FROM DBA_TS_QUOTAS WHERE MAX_BYTES = 0 OR MAX_BLOCKS = 0;
This query will return any tablespace quotas with invalid specifications, such as a maximum size of 0 bytes or blocks.
Fixing the ORA-01228 Error
Once you have identified the invalid quota specification, you can fix the ORA-01228 error by adjusting the quota for the affected tablespace. There are several possible scenarios and corresponding solutions:
1. If the error is caused by an invalid quota for a specific user, you can adjust the quota using the following SQL statement:
ALTER USER username QUOTA {size} ON tablespace_name;
Replace “username” with the affected user’s name, “{size}” with the desired quota size, and “tablespace_name” with the name of the affected tablespace.
2. If the error is caused by an invalid quota for a specific tablespace, you can adjust the quota using the following SQL statement:
ALTER TABLESPACE tablespace_name QUOTA {size} ON username;
Replace “tablespace_name” with the affected tablespace’s name, “{size}” with the desired quota size, and “username” with the affected user’s name.
3. If the error is caused by an invalid quota for a specific data file, you can adjust the quota using the following SQL statement:
ALTER DATABASE DATAFILE 'datafile_path' RESIZE {size};
Replace “datafile_path” with the path to the affected data file, and “{size}” with the desired quota size.
4. If the error is caused by an invalid quota for a specific tablespace group, you can adjust the quota using the following SQL statement:
ALTER TABLESPACE GROUP group_name ADD DATAFILE 'datafile_path' SIZE {size};
Replace “group_name” with the affected tablespace group’s name, “datafile_path” with the path to the affected data file, and “{size}” with the desired quota size.
Conclusion
In conclusion, the ORA-01228 error in Oracle indicates an invalid quota specification for a tablespace. By diagnosing the specific quota causing the issue and adjusting it accordingly, you can resolve the error and ensure the proper allocation of storage space in your database.
