I develop in Pl*Sql, then run the procedures via Unix / Sql * Plus, the program reads flat files on Unix.

But how do I debug this, since the Pl*Sql Windows session doesn't recognize Unix ? Do I put the file on Windows ? If so, how do I read that ?

I read the Unix files like this:

fh_inp := UTL_FILE.FOPEN([UNIX FILE LOCATION],'fep_clm_clm_line_nwr76579.dat','R',2000);

UTL_FILE.GET_LINE (fh_inp, input_rec2);

you can't read remote files,  in this case your pc is "remote" to the db server.

you'll have to put your files on the unix server.

even when you are debugging from a windows client like pl/sql developer, toad or sql developer,  the pl/sql itself is still executing on the db so the unix file is local to the execution there

sdstuber, ok, thanks.

are you saying I should be able to debug normally ? I always thought I couldn't debug from Pl*Sql Developer when reading a flat file from Unix.

shouldn't be a problem,  you can't "step into" the utl_file procedures themselves anyway,  so the location of those files is irrelevant.

PL/SQL file operations are performed on server machine i.e. the machine where oracle is installed.

Consider the example below
CREATE OR REPLACE DIRECTORY MY_DIR AS '/uo1/my_data'
/

set serveroutput on
declare
    f utl_file.file_type;
    s varchar2(200);
begin
    f := utl_file.fopen('MY_DIR','sample2.txt','R');
    loop
        utl_file.get_line(f,s);
        dbms_output.put_line(s);
    end loop;
exception
    when NO_DATA_FOUND then
        utl_file.fclose(f);
end;

Open in new window

/

Though I am running the SQL block on the client machine.  The dIrectory MY_DIR has to be on the server machine.

You can find directories defined all_directories
