Hi all,
I'm at SCO UNIXWARE 7.1.1, my system's memory is larger than dump device, I have found one kernel tunable parameter at SCO website ie SYSDUMP_SELECTIVE which tells me that if set to 1 system will dump only kernel mapped memory, but I'm not sure how to configure this parameter.

I want to change some kernel parameters in HP-UX11, to do with Oracle upgrade/install.
I know this is done using SAM. I am told SAM will not let you enter values outside the allowable range. Could anyone tell me if they have experienced anything different?
In Solaris, I would copy the... (2 Replies)
Hello all, Can anyone tell me the command line I can use to look at the following Kernel parameters:
nfile
maxfile
maxfile_lim
I'm using the Reflection manager connection to my Unix box so I can't use SAM. (3 Replies)
I've been trying to find out the following parameters of our Unix box:
==>OS version
==> patch level
and the following kernel parameters
=>maxfiles_lim
=>maxvgs
=>nproc
=>msgmni
=>ncsize
=>nfile
Could someone help me how would I find the above(commands)?
Thanks,

Hi gurus
Could anybody tell me which file is read by kernel to set its default system kernal parameters values in solaris. Here I am not taking about /etc/system file which is used to load kernal modules or to change any default system kernal parameter value
Is it /dev/kmem file or something... (1 Reply)
Hi,
if I install a module with specific parameter, will this parameters applied next time system boots?
for exampe, I want to disable InterruptThrottleRate

profil
PROFIL(2) BSD System Calls Manual PROFIL(2)NAME
profil -- control process profiling
LIBRARY
Standard C Library (libc, -lc)
SYNOPSIS
#include <unistd.h>
int
profil(char *samples, size_t size, u_long offset, u_int scale);
DESCRIPTION
The profil() function enables or disables program counter profiling of the current process. If profiling is enabled, then at every clock
tick, the kernel updates an appropriate count in the samples buffer.
The buffer samples contains size bytes and is divided into a series of 16-bit bins. Each bin counts the number of times the program counter
was in a particular address range in the process when a clock tick occurred while profiling was enabled. For a given program counter
address, the number of the corresponding bin is given by the relation:
[(pc - offset) / 2] * scale / 65536
The offset parameter is the lowest address at which the kernel takes program counter samples. The scale parameter ranges from 1 to 65536 and
can be used to change the span of the bins. A scale of 65536 maps each bin to 2 bytes of address range; a scale of 32768 gives 4 bytes,
16384 gives 8 bytes and so on. Intermediate values provide approximate intermediate ranges. A scale value of 0 disables profiling.
RETURN VALUES
If the scale value is nonzero and the buffer samples contains an illegal address, profil() returns -1, profiling is terminated and errno is
set appropriately. Otherwise profil() returns 0.
FILES
/usr/lib/gcrt0.o profiling C run-time startup file
gmon.out conventional name for profiling output file. This may be different if the PROFDIR environment variable is set.
ERRORS
The following error may be reported:
[EFAULT] The buffer samples contains an invalid address.
SEE ALSO gprof(1), moncontrol(3)BUGS
This routine should be named profile().
The samples argument should really be a vector of type unsigned short.
The format of the gmon.out file is undocumented.
