sys.aud$ issue in OUA DB
The following query is observed to put a heavy load on OUA production DB server:
SQL Id: 4ztz048yfq32s
SELECT TO_CHAR(CURRENT_TIMESTAMP AT TIME ZONE 'GMT', 'YYYY-MM-DD HH24:MI:SS TZD') AS curr_timestamp,
COUNT(username) AS failed_count,
TO_CHAR(MIN(TIMESTAMP), 'yyyy-mm-dd hh24:mi:ss') AS first_occur_time,
TO_CHAR(MAX(TIMESTAMP), 'yyyy-mm-dd hh24:mi:ss') AS last_occur_time
WHERE returncode != 0
AND TIMESTAMP >= CURRENT_TIMESTAMP - TO_DSINTERVAL('0 0:30:00');
This query is executed by Oracle Enterprise Manager (OEM or EM) running on OUA DB server .
It's responsible for large part of I/O load on the database, therefore decreasing available performance of server.
Query performance is poor because of large number of records in SYS.AUD$ database table, which keeps audit trail of all database logins.
