oracle11g - Oracle external table logfile showing file not found when table not accessed -


we're using in oracle 11g release 2 oracle_loader type external table import data csv file table. external table has dummy filename set location value, users entering correct filename parameter when package run. package code set location via alter statement.

there 1 package - , nothing else - using external table, , package run - once week. however, external table's logfile being updated every 4 hours, saying dummy file wasn't found (which, of course, wouldn't be):

 log file opened @ 05/10/13 22:00:12   kup-04040: file dummy_input_csv.csv in dir_extdir not found    log file opened @ 05/11/13 06:00:13   kup-04040: file dummy_input_csv.csv in dir_extdir not found    log file opened @ 05/11/13 10:05:07   kup-04040: file dummy_input_csv.csv in dir_extdir not found

from oracle documentation i've seen regarding managing , using external tables, thought external table's logfile updated when external table used via select statement retrieve data.

what else, outside of actual select, might cause external table go looking location file?

it might 1 of scheduled jobs trying access table, such automatic collection of statistics. see if there jobs in dba_scheduler_jobs or dba_autotask_client scheduled run @ time see error.
