有一条简单的update语句，每次只更新一条记录，
update table t set T.A = :1 , T.B = :2 , T.C = :3 WHERE 1 = 1 AND T.PHON_NUM = :4 AND T.E = :5 AND T.F = :6

T表数据量大概五千万，where条件有走索引
这个语句从AWR看大概每小时执行两百次

SELECT s.username,decode(l.type, ‘TM’, ‘TABLE LOCK’, ‘TX’, ‘ROW LOCK’, NULL) LOCK_LEVEL,o.owner,o.object_name,o.object_type,s.sid,s.serial#
FROM gv$session s, gv$lock l, dba_objects o WHERE l.sid = s.sid AND l.id1 = o.object_id(+) AND s.username is NOT NULL
用这个语句抓取频繁出现该语句，是否正常？
