Subject: memory related problems
Hi,
I've got some strange memory related problems on my test environment.
Here is my configuration:
System memory32GB
--oracle
sga_max_size24G
sga_target 24G
pre_page_sgaTRUE
pga_aggregate_target4G
--sysctl.conf
kernel.shmmax = 25316935680
kernel.shmall = 12361785
vm.nr_hugepages = 12293
--limits.conf
oracle hard memlock 25176064
oracle soft memlock 25176064
I've started oracle from sqlplus - everything works as expected:
total used free shared buffers cached
Mem: 32192 26620 5571 0 23 722
Swap: 20191 0 20191
HugePages_Total: 12293
HugePages_Free: 4
HugePages_Rsvd: 0
Hugepagesize: 2048 kB
Then, oracle autostart disabled ->reboot of server->sqlplus ->startup -> OK :)
But...I've enabled autostart (srvctl), restarted server and then problems
appears - a lot of swapping, high server load, oracle processes psp, mman, lmon
at 70-80% cpu and in the end:
Process MMAN died, see its trace file
USER: terminating instance due to error 443
after that I can with no problems start database with sqlplus, but when I stop
it again and try start it with srvctl - the same...swappping, high load etc...
any ideas where is the problem ?
thanks
