Re: HPUX Error: 23: File table overflow
The number of open files allowed by the kernel's 'nfile' parameter has been exceeded. You will need to increase this (via SAM (Kernel COnfiguration)) and reboot. You can use 'glance' to check the current nfile utilization via the [t]able report.

Re: HPUX Error: 23: File table overflow
you may want to do a search in the forums for "file table" for more info, but here is a link to start you off:

Re: HPUX Error: 23: File table overflow
This is most easily done via SAM and will require the kernel to be rebuilt and will also require that the system be rebooted in order for the new kernel to take effect.
Have a look at this link for more info. Though this is an old document, it is still valid.

Re: HPUX Error: 23: File table overflow
If you check the following:
# grep 23 /usr/include/sys/errno.h
ENFILE ....
# man errno
Search for ENFILE
[ENFILE] File table overflow. The system's table of open files is full, and temporarily no more open()s can be accepted
Check if the kernel parameter, nfile, has a formula: with maxusers include.
Then it's better to increase maxusers(double it).

Re: HPUX Error: 23: File table overflow
If nothing has changed on Oracle side, I am talking mostly about amount of data, type of processing, etc, then you would might have to look on the Oracle side too.
There is no harm in increasing the kernel parameter, but its better to be sure that indeed that is the problem. Otherwise, a couple of days later, you might be troubleshooting the same problem again.

Re: HPUX Error: 23: File table overflow
I have experienced the same problem, I fixed it increasing parameter maxuser.
I like to know more about but I cannot follow the links you put above.
Any idea if they are still valid?, or any documentation for tuning kernel parameters.
Thank you!

Re: HPUX Error: 23: File table overflow
Here is a link that should help.
http://www.docs.hp.com/hpux/os/11.0/index.html#System%20Administration
There are two pages which would be of interest:
Configurable Kernel Parameters (HP-UX 11.0)
and
HP-UX Kernel Tuning and Performance Guide (HP-UX 11.0)

Re: HPUX Error: 23: File table overflow
It's problem with the nfile paramater in kernel. Probably your oracle dba's might have done a few changes recently, and that change might have requested for more files to be opened simultaneously, which might be more than the limit specified by the nfile parameter in the kernel.
I have faced the same problem and have got it done by increasing the value of nfile.
Hope this helps
Cheers !!!
