*Cause: An attempt was made to do one of the following :
(1) create a temporary tablespace with a non-standard block
(2) alter an existing permanent tablespace of non-standard
block size to a temporary tablespace or,
(3) issue a DDL statement that would result in the creation
of a temporary segment in a tablespace of non-standard
*Action: (1) If creating a temporary tablespace, do not specify a block
size different from the standard block size.

temporary tablespace, ensure that it is of standard block size.
(3) Ensure that the user's temporary tablespace is a
tablespace having the standard block size.
