First of all, your method_opt is erroneous. You should specify something like
'FOR ALL COLUMNS SIZE SKEWONLY' or 'FOR ALL COLUMNS SIZE AUTO' or Wolfgang's
favorite option 'FOR ALL INDEXED COLUMNS SIZE <histogram size>'.
Second, the basic error is "ORA-00979 Not a group by expression", not 6512.
You can catch the SQL statement throwing the error by issuing the following
commands:
ALTER SYSTEM SET TRACEFILE_IDENTIFIER=STATS;
ALTER SYSTEM SET EVENTS='979 TRACE NAME ERRORSTACK FOREVER, LEVEL 12';
That will catch the statement causing ORA-00979. If that doesn't help,
you have to deal with a bug and should contact Oracle support. You didn't
specify the version and the platform, which would expose you the the danger
of sybranding in some other forums, but if you can, I advise you to upgrade
to the highest patch level for your version.
