ORA-14521: Default tablespace string block size [string] for string string does not
match existing string block size [string]
Cause: A DDL statement wasissued that would require creation of a new
partition/subpartition in the object-level default tablespace of an existing
partitioned object. However, the object-level default tablespace block size doesnot
match the block size of the partitioned object.
Action: Either (1) Modify thedefault tablespace of the partitioned object to a
tablespace of the same block size as the object and then retry the DDL command,
OR (2) Ensure that tablespaces of the correct block size are specified for allnew
partitions/subpartitions being created.
