Oracle ORA-30022: Undo Tablespace Full
Description
The ORA-30022 error indicates that Oracle Database cannot create new segments in the undo tablespace. This typically occurs when the undo tablespace is full or configured incorrectly, preventing the database from managing transaction rollback information.
Error Message
ORA-30022: Cannot create segments in undo tablespace
Known Causes
4 known causesInsufficient Undo Tablespace Size
The undo tablespace does not have enough space to accommodate current transaction load. Increase the undo tablespace size to accommodate peak transaction activity.
Incorrect Undo Retention
The undo retention period is too long, leading to the undo tablespace filling up quickly. Reduce the `UNDO_RETENTION` parameter to a more appropriate value.
Autoextend Disabled
The undo tablespace datafiles are not configured to autoextend, preventing them from growing automatically when needed. Enable autoextend on the undo tablespace datafiles.
High Transaction Volume
An unusually high volume of transactions is generating excessive undo data. Investigate and optimize any long-running or resource-intensive transactions.
