VMunix table full error
Currently I am getting an error messages in the syslog .
"vmunix: file: table is full "
Can you advice on what should be done ?
We are using a HP-UX B.11.11 U 9000/800 superdome machine .
Moreover I could see that oracle is automatically shutting down. Does this has anything to do with Vmunix table ?
Regards
Kiran

Re: VMunix table full error
You have exceeded the limit for the maximum number of files which can be opened at time which is controlled by the kernel parameter, NFILE.
You have to modify this kernel parameter either through SAM or command mode and reboot the machine to avoid getting this error message in the future.
This could be one probable reason why your oracle database is shutting down automatically

Re: VMunix table full error
Please have a look at the man pages for nfile before doing the modifications.
http://docs.hp.com/en/B2355-60103/nfile.5.html
I think you can increase to 16384 and do a close watch on how the system is performing.

Re: VMunix table full error
As stated in Oracle Metalink, the recommended nfile for Oracle 9.2.0 is:
NFILE=(15*NPROC+2048)
where NPROC=4096
thus, 16327 is low.

Re: VMunix table full error
the oracle shutdown could easily be caused by that, oracle has no other choice in that situation short of dropping user sessions.
