ORA-14521: Default tablespace string block size [string] for string string does not match existing string block size [string]
Cause : A DDL statement was issued 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 does not match the block size of the partitioned object.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Either (1) Modify the default 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 all new partitions/subpartitions being created.
Well, the reason for above error is that i have taken the above script from a 11g database and running it on 10g database. 11g has bring some changes in password management. Below code is executed on 11g and user created successfully, which is expected result.
