Solution for Oracle Error ORA-14057

ORA-14057: partition "string": sum of PCTUSED and PCTFREE may not exceed 100

What triggered the Error:

the sum of PCTUSED and PCTFREE for a partition whose name (explicitly specified by the user) is displayed in this message exceeds 100. Note that if PCTUSED and/or PCTFREE values for this partition were not specified explicitly, default values for the partitioned table or index would be used. If, in turn, default PCTUSED and/or PCTFREE values for the partitioned table or index were not specified, system defaults would be used.

What should we do to fix it:

ensure that a sum of PCTUSED and PCTFREE for the partition does not exceed 100
