Unable to additionally input or modify data using the INSERT or UPDATE statement.
This error occurs when data input fails due to insufficient space in the tablespace.
1. Increase the tablespace size by adding a datafile to the tablespace on which the error has occurred.
2. If the undo tablespace caused the error, COMMIT/ROLLBACK operations are unsuccessfully carried out for a long time.
Check whether a transaction using undo tablespace exists.
Since DML operations fail due to insufficient space in the tablespace, try again after increasing the tablespace size.
