ORA-29283: invalid file operation tips

Oracle Error Tips by Stephanie F.

 

Also see ORA-29283 with impdp network_link.  The Oracle docs note this on the ORA-29283 error:

ORA-29283: invalid file operation
 
Cause: An attempt was made to read from a file or directory that does not exist, or file or directory access was denied by the operating system.
 
Action: Verify file and directory access privileges on the file system, and if reading, verify that the file exists.

If this is similar to something you are experiencing, you may want to read further.  Here is the Test case provided about ORA-29283:

1. On the OS run the following to define a system variable:
define/system MYDIR VMS"""user password"""::$1$DG:[SUPPORT.MYDIR]

2. In sqlplus create the directory object to map the logical directory:
Create or replace directory rtvms2 as 'MYDIR:';

3. Run now the following procedure to create the remote file:


SET SERVEROUT ON

declare
v_buff VARCHAR2(2000);
fhandle UTL_FILE.FILE_TYPE;
begin
dbms_output.put_line('WRITE');
fhandle:= UTL_FILE.FOPEN('MYDIR:','Report.txt','W');
UTL_FILE.put_line(fhandle,' Attempt to write');
UTL_FILE.FCLOSE(fhandle);
end;
/

SQL>
WRITE

PL/SQL procedure successfully completed.

SQL> HOST dir mydir:
Directory VMS"user password"::$1$DG:[SUPPORT.MYDIR]

REPORT.TXT;1 1/69 29-DEC-2005 10:23:58.39 (RWD,RWD,R,)


4. Now test the append to the remote file, this will create a new version of the file

declare

v_buff VARCHAR2(2000);
fhandle UTL_FILE.FILE_TYPE;
begin
dbms_output.put_line('APPEND');
fhandle:= UTL_FILE.FOPEN('MYDIR:','Report.txt','A');
UTL_FILE.put_line(fhandle,'attempt to append');

UTL_FILE.FCLOSE(fhandle);
end;
/


SQL>
APPEND

PL/SQL procedure successfully completed.

SQL> exit

dir mydir:
Directory VMS"user password"::$1$DG:[SUPPORT.MYDIR]

REPORT.TXT;2 1/69 29-DEC-2005 10:23:58.73 (RWD,RWD,R,)
REPORT.TXT;1 1/69 29-DEC-2005 10:23:58.39 (RWD,RWD,R,)

edit REPORT.TXT;1
Attempt to write
[End of file]

edit REPORT.TXT;2
attempt to append
[End of file]



5. And finally test the read operation on the remote file:

declare
v_buff VARCHAR2(2000);
fhandle UTL_FILE.FILE_TYPE;
begin
dbms_output.put_line('READ');
fhandle:= UTL_FILE.FOPEN('MYDIR:','Report.txt','R');
-- UTL_FILE.get_line(fhandle,v_buff);
UTL_FILE.FCLOSE(fhandle);
end;
/

SQL>
READ
declare
*
ERROR at line 1:
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 449
ORA-29283: invalid file operation
ORA-06512: at line 6

The reason that these errors are being thrown, including ORA-29283, is related to an OS issue, "elated to the access() C RTL in OpenVMS, which is used by the utl_file.fopen to know if the file exists or not. The access() returns success when the file is local, but for a remote file access() returns failure." 

The ult_file.fopen fails when it attempts to read a remote file with ORA-29283, because it is using the access() routine, and "and it fails when appending to a remote file because it creates a brand new file even if the file specified exists"

The following solution ids given to resolve ORA-29283:

The cause of the problem lies in the access() OpenVMS C runtime library which does not work with remote files, so there is no fix for this from an Oracle point of view
