Hi,
I was wondering if someone maybe knew what is stored in the following memory
array and maybe give a clue as in why it is not released anymore:
I have 1 agent which reports the following using pmap:
# "pmap -x 9659
9659: db2sysc
Address Kbytes Resident Shared Private Permissions Mapped
File
000000010000000 0 26312 10072 9696 376 read/exec db2sysc
0000000101AB000 0 3024 648 512 136 read/write/exec db2sysc
0000000101DA400 0 115992 76872 8 76864 read/write/exec [
heap ]
000000020000000 0 13152 13152 - 13152 read/write/exec [
anon ]
000000021000000 0 5434368 5434368 - 5434368 read/write/exec [

anon ]
....
FFFFFFFF7FFDE00 0 136 112 - 112 read/write [
stack ]
And then another agent which after the application connected has not been
used has the following:
# "pmap -x 3066
3066: db2sysc
000000010000000 0 26312 10368 9992 376 read/exec db2sysc

heap ]
000000020000000 0 13152 13152 - 13152 read/write/exec [

000000021000000 0 5434368 5434368 - 5434368 read/write/exec [

FFFFFFEF0000000 0 512 512 - 512 read/write/exec [
anon ]
....
FFFFFFFF7FFEE00 0 72 16 - 16 read/write [
stack ]
What I'm wondering about is the portion in the heap and stack.
The agent (3066) that has not been used (after application connected) has a
stack of 72KB and a heap of 1560KB. So I consider this to be the minimum
needed.
But then the other agent (9659) has a stack of 136KB and a heap of
115992KB(= 113MB). Clearly, both the stack and the heap have grown. This
agent is currently in a committed status thus no open UOW or anything
actively running.
So my question is, what is stored in the stack and heap and how come it is
not being freed? What DBM and/or DB configuration parameters (if any)
control this?
Thank you.
