How do I resolve the following error, when connecting from a client after 170 connections are reached, to a 9i Release 2 db..

> > ORA-27102 error "out of memory"
> > HP-UX Error: 12: Not enough space

When I look in the listener.ora log files, I see the following error..

TNS-12500: TNS:listener failed to start a dedicated server process
TNS-12540: TNS:internal limit restriction exceeded
TNS-12560: TNS:protocol adapter error
TNS-00510: Internal limit restriction exceeded

Saty,

It is problem with your kernel parameters. You need to increase your shmmax kernel parameter.

Hi Check the file system sizes or else give the bdf output.

ALso check the database spaces.

Thanks,

Hi,

You should also check these threads:

Also check your dbc_max_pct kernel parm.
Possible on default value of 50% should be lowered for example to 5 or 10%

Re: HP-UX Error: 12: Not enough space

Hi:

Error 12 (out-of-memory) generally points to insufficient swap or too small a 'masxdiz'.

You appear to need more stack space. You can increase the kernel 'maxdsiz' ('maxdsiz_64bit' on 64-bit processors) to affect this.

Regards!

Hi Saty

from the forum:

ENOMEM can be caused by maxdsiz being setting too small but this sounds more like not enough swapspace or swapmem_on needing to be enabled.

Re: HP-UX Error: 12: Not enough space

Here's one more suggestion...on the Oracle side:

You could reduce your 'large_pool_size' value in your init.ora


I remember this was a suggestion from Oracle on the 27102 error....

Just a thought,

Re: HP-UX Error: 12: Not enough space

Hi guys,

me too gets this error

HP-UX Error: 12: Not enough space

There Swap space is : 1 gig

SHMMAX = maximum physical memory available ( 512 Meg).

Reboot doesnt work for me .

There are no other apps on this box and only one Oracle instance.

Re: HP-UX Error: 12: Not enough space

This is a very old theard.
Please raise a new thread.

The problem should be the shared memory kernel parameter.
