Question: I am getting the error
"ORA-20011: Approximate NDV failed: ORA-29913".
GATHER_STATS_JOB encountered errors.
Check the trace file.
Errors in file
c:\oracle\admin\diag\rdbms\trace\ri_j000_10912.trc:
ORA-20011: Approximate NDV failed:
ORA-29913: error in executing ODCIEXTTABLEOPEN callout
ORA-29400: data cartridge error
How do I address these errors?Answer:
This is a well-know Oracle issue with several solution
documents on MOSC (http://support.oracle.com)
. The ORA-20011 error is a custom
error. The ORA-29913 error is also not meaningful:
ORA-29913: error in
executing string callout.
Cause: The
execution of the specified callout caused an error.
Action: Examine the error messages take appropriate
action.
Solution:
First, see MOSC Note 1290722.1, which notes that the
solution to this issue is to clean up the orphaned
dictionary entries. Different solutions are appropriate
dependent on the exact nature of the primary cause and these
are outlined in the note.
Also see Bug number 10327346 titled "DBMS_WORKLOAD_CAPTURE
does not drop external tables (causing ORA-20011 from
DBMS_STATS)".
Also related are notes 1274653.1, MOSC Note
10327346.8, and Note 1305127.1.
