This ORA-1652 errors are related with the required number of blocks for a temporary segment in the tablespace indicated.

To solve this error, Use ALTER TABLESPACE ADD DATAFILE statement to add one or more files to the tablespace indicated as follow.

 

Check your temp tablespaces and its size.

select file_name,tablespace_name,bytes/power(2,30), maxbytes/power(2,30),autoextensible from dba_temp_files;

If you use the Oracle ASM, you can add the datafile as follows.
