Don't change it.
We have a very heavily used db. We get sporadic errors like this.
We have a poster as well --
It also has a few other error codes. Unless these errors recur all the time, or there are failed Oracle processes, you are probably unwise to tinker with maxuprc.
The point being:
these things happen mostly due to badly written user code, and you can't fix it by changing tunable kernel parameters.
metalink has a set of things to look for, a tedious long list, for both of these error code families. If a user has complained because a process fails, then you get to log onto metalink and spend the next few days researching. Often, the problem is user code or incorrect schema permissions (especially for weirdo 12nnn errors), not oracle or kernel parms....

shmmax
shmmax(5) File Formats Manual shmmax(5)NAME
shmmax - maximum size (in bytes) for a System V shared memory segment
VALUES
Default
Allowed values
DESCRIPTION
Shared memory is an efficient InterProcess Communications (IPC) mechanism. One process creates a shared memory segment and attaches it to
its address space. Any processes looking to communicate with this process through the shared memory segment, then attach the shared memory
segment to their corresponding address spaces as well. Once attached, a process can read from or write to the segment depending on the
permissions specified while attaching it.
This tunable sets the maximum size for such a segment within the system, and is dynamic as of HP-UX 11i.
Who is Expected to Change This Tunable?
Anyone.
Restrictions on Changing
Changes to this tunable take effect immediately.
When Should the Value of This Tunable Be Raised?
should be raised if it is below the maximum and user programs are attempting to segments larger than the current value, and receiving an
error message.
What Are the Side Effects of Raising the Value?
The only effect is that user programs can use to get larger segments.
When Should the Value of This Tunable Be Lowered?
If you wish to enforce behavior on the user's code, limiting the maximum size of System V segments.
What Are the Side Effects of Lowering the Value?
None.
What Other Tunable Values Should Be Changed at the Same Time?
and should be considered because enforcing smaller segments may cause the user's code to try to create more segments to accomplish the
task.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
