I'm running oracle 8.1.6 on W2K Server.
The other day I got TNS-12500 errors stating I'm out of processes.
This value is set to 500 and when I query the v$resource_limit view I see my max and current utilization are 387, well below my 500 limit.
I heard something about ghost processes?
What else could cause this error?
Any help would be great...

can u post the exact message?
becuase tns-12500 does not directly deal with process errors / resource errors.
and
MAKES SURE , that ther oracledatbase service and listener service is always started by a user with FULL ADMINISTRATIVE RIGHTS and in dba group

Mahesh,

Here is a bit of the listener log.
Our system is W2K Server 2-cpu, 2G memory.
At the time of this error the values in the v$resource_limit view where:
Name:processes,Current:447,Max:497,Initial:700,Limit:700
Other init values for session, transaction, enqueue_resources where defaulted based on the processes value 700

are u in Dedicated server or MTS?
increase the value of PROCESSES in initsid.ora
or
reduce the size of sga ( mostly becuase of unwanted huge large_pool_size)
or enable tracing to check whether there is an issue with DCD

u can just increase it (NOT TOOO HIGH).
But i have second thoughts about this as a solution.
this error
32-bit Windows Error: 8: Exec format error
is becuase of unavailablity of system resources.
We have manipulate the parameters that influence the resources
or make sure the resources are available.
so try
AUTOMATIC_IPC = OFF in your sqlnet.ora
and
WHAT IS THE UPTIME OF WIN2K server.
People are not happy with windows, IT WILL CREATE problems when UPTIME is prolongated.
try to reboot the system

the device is booted nightly.
the db is shutdown, backed up, and rebooted so the database comes up clean.

What will automatic_ipc=off do for me?
