Hi Andrew, long time no seen ;-)
And again with a kernel bug.
We already opened a bug with suse/novell and oracle on this issue.
I scanned the aio.c in the current SP3 kernel and new kernels...there are a
lot of smp/irq locking issues addressed in the new aio-version.
I don't meen the libaio, i mean the aio kernel layer.
We had 2 hanging oracle-installation the last 3 weeks on similar
hardware/application. Du the the kernel oops, you can't get rid of the
processes and the ipc-resource and have to reboot the machine.
I will keep you informed about these issues ;-)
Bye
frnak

Subject: [suse-oracle] Libaio kernel bug on SLES9 SP3 with 9.2.0.8
I received a kernel bug in my /var/log/messages and 0 seconds later my
oracle database hung, all I could do was "shutdown abort" even then the
database wouldn't restart. I'm rebooting right now.
The bug info is below. I've got libaio-0.3.102-1.2 installed which
appears to be the latest available through yast updates. Does anyone
have a more stable libaio for use with Oracle 9.2.0.8 running on SLES 9
with SP3?
Thanks
