ORA-14520: Tablespace string block size [string] does not match existing object block size [string]
Cause : A DDL statement was issued that would require a tablespace of a block size different from the block size of the specified partitioned object to be assigned either: (1) As the object's default tablespace (or one of the object's partition-level default tablespaces, if composite partitioning is being used) OR (2) To one of the object's partitions/subpartitions.
Action - How to fix it : DBA Scripts :: www.high-oracle.com/scripts
Specify a tablespace of the same block size as the partitioned object.
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.
