Oracle Error Description
ORA-14522: Partition-level default tablespace string block size [string] for string string does not match existing string block size [string]
Reason for the Error ORA-14522: Partition-level default tablespace string block size [string] for string string does not match existing string block size [string]
A DDL statement was issued that would require creation of a new subpartition in one of the partition-level default tablespaces of an existing composite partitioned object. However, the partition-level default tablespace block size does not match the block size of the partitioned object.
How to fix the Error ORA-14522: Partition-level default tablespace string block size [string] for string string does not match existing string block size [string] ?
You can fix this error in Oracle by following the below steps
Either (1) Modify the partition-level default tablespace of the appropriate partition 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 all new subpartitions being created.
