锁定Oracle更新语句的问题

Question

我的下面的查询被卡住了\挂起后提交，如何解决？

for i in tail -"$b" Locked.csv |cut -c1-7
do
sqlplus -s $TOA_DB <<! &2>1
set pagesize 0 feedback off verify off heading off echo off
update admsvc_lockinfo_t
set login_atmpts = 0, lock_status = 0 where obj_id0 in
(select POID_ID0 from service_t where login ='$i');

update service_t set PASSWD_STATUS =0  where login ='$i';

commit;

exit
