Datapump on Windows Platform

I was trying to do an impdp on a windows platform but I got the follwoing error:

ORA-39002: invalid operation
ORA-39070: Unable to open the log file.
ORA-29283: invalid file operation
ORA-06512: at "SYS.UTL_FILE", line 475
ORA-29283: invalid file operation

The obvious answer seems to be the Oracle Directory is not created or is missing read/write priviliges. However this was not the case. as teh following query showed:

SELECT d.owner,privilege, directory_name
FROM user_tab_privs t
, all_directories d
WHERE t.table_name(+)=d.directory_name
ORDER BY 3,2

The problem is that the directory was created using a mapped network drive which was mapped after Oracle was started. Oracle therefore could not read teh directory.
See:
Metalink : Doc ID: Note:221849.1

Symptom(s)
ORA-29283 Invalid file operation when accessing file on a mappeddrive using utl_file package

Cause
The reason for this error is because Oracle service isstarted using system account(default) which doesnt haveprivilege in the mapped folder.

OWB PARIS Problems

So far these are some of the OWB PARIS problems/bugs I have come across since started using it. This problems are happening when exports are made on a 64 bit windows machine into a 32 bits windows machine:

Problem:
- You change a process flow and deploy it, but it does not behave as the diagram shows.
Solution:
- Redo the entire process flow from scratch. A clue to the fact that the process flow will not behave in the same way as the diagram shows is to check the outgoing flows from a node. If the are the same numbers in <> it means there is a problem. Something that OWB should validate itself but thats the way OWB PARIS is at the moment.

Note: Work Flow Manager Client can show the errors on the process flow.

Problem:
- The columns to merge on are not set properly when mappings are imported from another OWB installation.
Solution:
- Reset the merge columns correctly again.
or Create the package in production only.
