Update query takes much time to execute

Question

Hi Experts,
I need help regarding performance of the query.
update TEST_TAB
set fail=1, msg='HARD'
where id in (
select src.id from TEST_TAB src
inner join TEST_TAB l_1 on src.email=l_1.email and l_1.database_id=335090 and l_1.msg='HARD' and l_1.fail=1
inner join TEST_TAB l_2 on src.email=l_2.email and l_2.database_id=338310 and l_2.msg='HARD' and l_2.fail=1
inner join TEST_TAB l_3 on src.email=l_3.email and l_3.database_id=338470 and l_3.msg='HARD' and l_3.fail=1
where src.database_id=1111111;
This query is running for too long, takes >1 hour and it updates 26000 records.
But, if we run inner select query
select src.id from TEST_TAB src
inner join TEST_TAB l_1 on src.email=l_1.email and l_1.database_id=335090 and l_1.msg='HARD' and l_1.fail=1
inner join TEST_TAB l_2 on src.email=l_2.email and l_2.database_id=338310 and l_2.msg='HARD' and l_2.fail=1
inner join TEST_TAB l_3 on src.email=l_3.email and l_3.database_id=338470 and l_3.msg='HARD' and l_3.fail=1
where src.database_id=1111111
It takes <1 minute to execute.
Please give me suggetions in the update query so that i will improve performance of the query.
