HP-UX : Directory Alias & UNIX account [message #159767]

Hi,

Our Oracle 10Gr2 OLAP db runs on a HP-UX server.

We would like to create this kind of directory :

CREATE OR REPLACE DIRECTORY my_test AS '$path';

where $path is set at the logon of an unix user. This directory is used by an old EXPRESS program running with this package :

execute DBMS_AW.execute('call PIPX70')

1) Can anybody tell me if it is possible ?

2) In case of the first answer is 'yes', wich user has to set '$path' ???

Thanks in advance and sorry for my french poor english... Wink

I forgot this :

ERROR: (ORA-36786) File my_test/PIPX70 does not exist or cannot be accessed.
In EXPPGM!PIKX70 PROGRAM:
otf &joinchars(DIR_ALIAS(my_test _typfic) '/' _restit)

At unix login, you can insert your environment into a table. You can make the rows distinguishable per user by including the unix username or whatever in the insert statement.

I'm pretty sure there's no way to create a DIRECTORY object that dynamically determines its target.

The reason for DIRECTORY objects with READ/WRITE privs is because UTL_FILE and EOTs access the file system as the oracle user, with all its inherent privs.

If you could dynamically change the target of a DIRECTORY, you could point it to $ORACLE_HOME and start blowing away files - or worse - point it to the location of the DB data files.

   EXECUTE IMMEDIATE 'create or replace directory MY_PATH as '''||v_path||'''';
   --EXECUTE IMMEDIATE 'grant read on directory MY_PATH to PUBLIC';

Ross it correct - the directory definition can be changed dynamically, but all concurrent users will access the last definition.
