Symptoms

After upgrading ogg from 11.2.1.0.31 t o12.1.2.1.9, we are seeing the following query in our performance test environment running a very large number of times almost continuously. In production we see it run once or twice an hour max. Do we have something configured incorrectly in 12.1 causing the query to run so often? Is there a way to change how often it runs?

SQL = dr97hbjraumrm
SELECT 1 FROM V$LOGFILE WHERE(STATUS NOT IN ('STALE', 'INVALID') OR STATUS IS NULL) AND MEMBER <> :log_name AND EXISTS ( SELECT 1 FROM V$LOG WHERE GROUP# = V$LOGFILE.GROUP# AND THREAD# = :ora_thread AND SEQUENCE# = :ora_seq_no ) AND ROWNUM = 1
