HP-UX

Hi UNIX guru's,

Have recently upgraded Oracle from 8i to 10g on an HP-UX (RISC) 11.11 box.

At least twice a day the database stops accepting incoming connections and the following errors are observed in the various logs.

The box needs to be rebooted to get everything going again.

The box has 6GB of physical ram and I belive 2 x 2GB swap files.

Does anyone one know what the HPUX Error: 12: Not enough space
error is referring to.

The kernel parameters have been configured according to the Oracle upgrade guide.

Also referring to the last error log which was observed when rebooting, what is aux swap space, is it a problem that we havn't got any?

Any help would be appreciated.

Cheers Mat

after upgrade from 816 to 10G:
the database stops accepting new connections.

Do a "swapinfo -t" to see how much swap you really have. It looks like you have typos in /etc/fstab. Review which logical volumes you really have and which lv's you actually want to use as swap areas.

Hi,
Thanks for your reply.

I am unable to to do a swapinfo -t as I'm not in front of the machine.
But a previous swapinfo -a returned

Code:

         Kb         Kb         Kb        PCT   START/ Kb
TYPE AVAIL      USED     FREE     USED  LIMIT  RESERVE PRI    NAME
dev   2146304    0       2146304  0%    0        -           1    /dev/vg00/1vol2
dev   2048000    0       2048004  0%    0        -           1    /dev/vg00/1vol9
reserve        -   4192820  -4192820
memory 4786844 3352124 1434720 70%

This tells me that the box is not using any swap at all and using 70% of its memory, do you know what the reserve figures mean.
Am I correct in my assumptions?
Any other ideas?

Thanks

Mat

We need the "swapinfo -t" output. The -a output is worse than useless, it's misleading. "Used" means paging has occurred...something was written to the swap area. "Reserved" means needed for stuff in core now in case of paging. If you cannot reserve, you are out of vm.

Hi,

Here is the output from swapinfo -t

Sorry for taking so long to get back to you.

Thanks

Mat
