tablespace datafile size

we have database which previously resided in EXADATA and then moved to a standalone linux host in which im seeing undo  datafile size as 100g,as far as i know normal tablespaces wouldnt exceed 32g size of datafile unless it is a bigfile tablespace,i see this weird situation where normal tablespace has 100g size..

is that possible to have datafile size like this..?

SQL> SELECT tablespace_name, bigfile FROM dba_tablespaces;

TABLESPACE_NAME                BIGFILE

------------------------------ ------------

UNDOTBS1                       NO

           FILE_NAME                                     SUM(BYTES/1024/1024/1024)  

---------------------------------------------------  ------------------------------

data_D-OBIAPRD_I-1778060744_TS-UNDOTBS2_FNO-11_p8nkgims         100

Thanks!
