sqlplus error on select from external table: ORA-29913: error in executing ODCIEXTTABLEOPEN callout

Question

I have setup a simple Oracle external table test that I (alongside a DBA and Unix admin) can\'t get to work.

The following is based on Oracle\'s External Tables Conc

Answer 1

We faced the same problem:

ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error error opening file /fs01/app/rms01/external/logs/SH_EXT_TAB_VGAG_DELIV_SCHED.log

In our case we had a RAC with 2 nodes. After giving write permission on the log directory, on both sides, everything worked fine.
