RE: ora-12500 on windows

Hello Jeffrey,

I'm feeling your pain, like you wouldn't believe.

I think it's note 225349.1

My problem that is resulting in ora-12500's is many, many connections
being fired at one time. Informatica fires in the neighborhood of 300
connections all at the same time, the exact same second. I have tried
adding multiple listeners, adding the QUEUESIZE parameter, all to no
avail. I had to reduce the sga size to stop the errors.

To make this more interesting, I am guaranteed that in the future there
will be several hundred more concurrent connections added to what I'm
dealing with now.

Can anyone comment - can MTS help in my situation? I've never used it.


Any comments or suggestions are welcome.

we are w2k AS. Do you know the metalink note for large memory support?

familiar territory.

on win32, the process memory limit is between 1.7 and
1.8 GB of virtual memory. what version of operating
system is the server running?

if it is w2k server, you're stuck. you must reduce
either the SGA or PGA memory allocations in order to
stay under the process limit.
if it is w2k advanced server, you can enable large
memory support, and carry up to a 3*10E9 (convert to
power of 2) memory allocated to a process.

if is is w2k3 server, you can enable large memory
support.
certain versions of Oracle on win32 support large
memory, and some don't.
9.2.0.4 does.
8.1.7.3 and 8.1.7.4 do not.

to reduce memory allocations, you might:
- check v$sgastat for free memory, and reduce the size
of the shared, large and java pools.
- reduce the buffer cache
- reduce sort_area_size, hash_area_size

hth.
