Hello Managers,
I could use some advice on a memory problem please, I just can't figure
this one out, I thought I had it but not quite.
The scenario is this: ES40 10Gb ram, 2-833CPU , 5.1, we have a custom
application that runs alongside oracle, and when the app is run it fails
halfway through with a segmentation fault. Oracle and the app call it
'foo' start to steal back and forth the ram available. I have 4Gb of
swap space set to disk0b, but I don't understand how to increase it if the
partition on either side of dsk0b are used. My other partitions, dsk0g
and dsk0h are used.
A listing of sysconfigdb proc and vm are:
proc:
max-proc-per-user = 1024
max-threads-per-user = 4096
maxusers = 2048
task_max = 1024
per_proc_stack_size = 16000000
max_per_proc_stack_size = 4026531840
per_proc_data_size = 8589934592
max_per_proc_data_size = 8589934592
max_per_proc_address_space = 8589934592
per_proc_address_space = 8589934592
# /sbin/sysconfigdb -l vm
vm:
swapdevice = /dev/disk/dsk0b
vm-swap-eager = 1
vm_mapentries = 300
vm_segmentation = 1
A listing of swap is:
Swap partition /dev/disk/dsk0b (default swap):
Allocated space: 524288 pages (4.00GB)
In-use space: 1 pages ( 0%)
Free space: 524287 pages ( 99%)
Total swap allocation:
Allocated space: 524288 pages (4.00GB)
Reserved space: 66746 pages ( 12%)
In-use space: 1 pages ( 0%)
Available space: 457542 pages ( 87%)
The advfs filesystem is 6 drives in Raid5 with about 80Gb on dsk0h, but
since it is in use and 80% messing with it is out of the queston right?
How do you add swap on a box that is using the dsk0h?
I have been using the system tuning guide and system administration guide
as well.
As always I appreciate the help!
