Solution:

First step is to check for temp tablespace and assosiation with users.

select username, temporary_tablespace, account_status from dba_users where username not like '%SYS%';

If  temporary_tablespace exists (TEMP) move to step2 to check datafiles assosiated with the tablespace as below:

Issue No data File associated with temp tablespace:
SQl>Select file_name from dba_temp_files;
No row selected
As you can see there is no data file associated with Temp tablespace;this is the reason of the issue.

To solve the issue simply add a datafile to the temp tablespace using the below command:

SQL>Alter tablespace Temp ADD TEMPFILE '/Data/Oracle4/oradata/new12/MyTemp.dbf' size 500M;

Check again to confirm:(Issue Resolved)
SQl>Select file_name from dba_temp_files;

output:  '/Data/Oracle4/oradata/new12/MyTemp.dbf'
