SQL>  select FILE_NAME,TABLESPACE_NAME from dba_temp_files;

ERROR at line 1: ORA-01157: cannot identify/lock data file 201 - see DBWR trace file ORA-01110: data file 201: '/oradata_nocg/temp01.dbf'

In the database I don't have '/oradata_nocg/temp01.dbf', I am not doing any operation related temp tablespace Why it is not allowing run above select query. ?

  • First you check your temp file is exist on specific location or not. from this query SQL>select file#,status,name from v$tempfile; and SQL> select * from v$tempfile; – Md Haidar Ali Khan Sep 10 '15 at 5:28

Most likely this is in a database that was cloned from an other database and the tempfiles are not added. Oracle needs a functional temporary tablespace to be able to process joins and sorts. dba_temp_files is a view that does this.

Solution is to simply add a few tempfiles to the temporary tablespace.
