One of my clients reported to me below warning in Alertlog
Mon Aug 8 10:48:01 2011
Memory Notification: Library Cache Object loaded into SGA
Heap size 2935K exceeds notification threshold (2048K)
KGL object name :select
service_name, uio_waits, uio_time, con_waits, con_time,
adm_waits, adm_time, net_waits, net_time
from
(select
stat1.service_name service_name, db_time, uio_waits, uio_time,
con_waits, con_time, adm_waits, adm_time, net_waits, net_time
from
(select s1.service_name,
sum(decode(s1.stat_name, ‘DB time’, s1.diff, 0)) db_time
from
(select e.service_name service_name,
e.stat_name stat_name,
So what is this about?
The solution was well documented in Memory Notification: Library Cache Object Loaded Into Sga [ID 330239.1]
The client is using 10.2.0.1 which the threshold limit is 2MB, in 10.2.0.2 the limit was increased to 50MB which should be enough in most cases
Happy debugging
Cheers
