why only sys user can read external table?

Hi team,

I have created external table under a user sirtest but only sys can read the external table.

Do you know how to fix that?

as user srtest:

 

select * from T1

*

ERROR at line 1:

ORA-29913: error in executing ODCIEXTTABLEOPEN callout

ORA-29400: data cartridge error

KUP-04040: file test_in.csv in ORCL_SIR_INPUT not found

as user sys:

SQL> select * from sirtest.t1;

A          B          C

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

10001        testrow       helloworld

10002        testrow       helloTaf

Thank You

Best regards
