Error in Executing ODCIEXTTABLEOPEN Callout

This ORA-29913 errors are related with the Privileges at the OS level.

To solve this error, Change permissions on the directory to allow the Oracle user to read and write from it.

Let’s go to see on the following example.

create directory meta_data as '/home/oracle/customer/meta_data';
grant read, write on directory meta_data to cartl01;

The foo.dat file was placed in the meta_data directory at the OS level
In this case the file only contained a single line with number ‘100’.

Create the next external table:

CREATE TABLE FOO
(
  NUM  NUMBER(10)
)
ORGANIZATION EXTERNAL
  (  TYPE ORACLE_LOADER
     DEFAULT DIRECTORY META_DATA
     ACCESS PARAMETERS
       ( records delimited by newline
    NOLOGFILE  )
     LOCATION ('foo.dat')
  )
REJECT LIMIT 0
NOPARALLEL
NOMONITORING;

Select from the external table encounters the error:

SQL> show user
USER is "CARTL01"

SQL> select * from foo;
select * from foo
*
