Error Querying Contents of External Table

Question

I get the error below from JDeveloper when I try to query the contents of an external table that I created in OWB. The Validate, Generate & Deploy actions were successful on the External Table. The location ALAN_TARGET_LOC_FILES_LOC resolves to where the flat files that the external tables refer to reside on Linux Server. This seemed to work fine last week… Any ideas what may have broke?
ORA-29913: error in executing ODCIEXTTABLEOPEN callout

Answer 1

Is there any way to find out the physical path
that 'owbdir' resolves to?
owner directory_name directory_path
SYS     ALAN_TARGET_LOC_FILES_LOC     owbdirSeems to me that the directory path is wrong. Under directory path you should see the real physical path you specified when you created the directory. Here's what select * from all_directories shows on my system (excerpt):
OWNER DIRECTORY_NAME DIRECTORY_PATH
SYS LOC_COCKPIT_OWB_LOC_FLAT_FILES E:\DATEN\01_ENTWICKLUNG\07_BEWIRTSCHAFTUNG\FF_DATEN\
As you can see directory path contains the physical path where my flat files reside.
