make sense and corrected the script(though earlier it was running fine (), don't know how).
Currently I'm trying to get the command I'm running using below sample test script:
Output:
Still I'm not getting the command, so that I can awk'ed the passed argument and put into a file. So the logic will be:
Once I'll restart script:
if this new file exist
take this new file
else
use old config file
once successfully done, I'll remove the error file (if any). Please suggest if this feasible.
Hi All,
I am working on solaris 8 sparc machine with 2 cpu.
I am trying to run my application which generates files. I run multiple instance of the application, but the results don't seem to show as if it were runing parallely.
When i run the application once it takes 12 secs to generate a... (1 Reply)

Hi
I am looking for some kind of feature in unix that will help me write a script that can invoke multiple processes in parallel. And make sure that the multiple parallel processes complete successfully before I proceed to the next step.

Hello everybody,
I have a little problem with one of my program. I made a plugin for collectd (a stats collector for my servers) but I have a problem to make it run in parallel.
My program gathers stats from logs, so it needs to run in background waiting for any new lines added in the log... (0 Replies)
Hello
I have a shell script with multiple sections in it. Like, verify pre-requisites, ch co version, stop services , install product , post migration steps, start services, send status email.
If the script fails at certain step, (like after product installation) it can't be re-run since the... (2 Replies)
I have 10,000 + files, each of which I need to zip using bzip2.
Is ti possible to use bash to create 8 parallel streams sending a new file to be processed from the list when one of the others has finished? (1 Reply)

X86_64_GET_MTRR(2) BSD/x86_64 System Calls Manual X86_64_GET_MTRR(2)NAME
x86_64_get_mtrr, x86_64_set_mtrr -- access Memory Type Range Registers
LIBRARY
x86_64 Architecture Library (libx86_64, -lx86_64)
SYNOPSIS
#include <sys/types.h>
#include <machine/sysarch.h>
#include <machine/mtrr.h>
int
x86_64_get_mtrr(struct mtrr *mtrrp, int *n);
int
x86_64_set_mtrr(struct mtrr *mtrrp, int *n);
DESCRIPTION
These functions provide an interface to the MTRR registers found on 686-class processors for controlling processor access to memory ranges.
This is most useful for accessing devices such as video accelerators on pci(4) and agp(4) buses. For example, enabling write-combining
allows bus-write transfers to be combined into a larger transfer before bursting over the bus. This can increase performance of write opera-
tions 2.5 times or more.
mtrrp is a pointer to one or more mtrr structures, as described below. The n argument is a pointer to an integer containing the number of
structures pointed to by mtrrp. For x86_64_set_mtrr() the integer pointed to by n will be updated to reflect the actual number of MTRRs suc-
cessfully set. For x86_64_get_mtrr() no more than n structures will be copied out, and the integer value pointed to by n will be updated to
reflect the actual number of valid structures retrieved. A NULL argument to mtrrp will result in just the number of MTRRs available being
returned in the integer pointed to by n.
The argument mtrrp has the following structure:
struct mtrr {
uint64_t base;
uint64_t len;
uint8_t type;
int flags;
pid_t owner;
};
The location of the mapping is described by its physical base address base and length len. Valid values for type are:
MTRR_TYPE_UC uncached memory
MTRR_TYPE_WC use write-combining
MTRR_TYPE_WT use write-through caching
MTRR_TYPE_WP write-protected memory
MTRR_TYPE_WB use write-back caching
Valid values for flags are:
MTRR_PRIVATE own range, reset the MTRR when the current process exits
MTRR_FIXED use fixed range MTRR
MTRR_VALID entry is valid
The owner member is the PID of the user process which claims the mapping. It is only valid if MTRR_PRIVATE is set in flags. To clear/reset
MTRRs, use a flags field without MTRR_VALID set.
RETURN VALUES
Upon successful completion zero is returned, otherwise -1 is returned on failure, and the global variable errno is set to indicate the error.
The integer value pointed to by n will contain the number of successfully processed mtrr structures in both cases.
ERRORS
[ENOSYS] The currently running kernel or CPU has no MTRR support.
[EINVAL] The currently running kernel has no MTRR support, or one of the mtrr structures pointed to by mtrrp is invalid.
[EBUSY] No unused MTRRs are available.
HISTORY
The x86_64_get_mtrr() and x86_64_set_mtrr() were derived from their i386 counterparts, which appeared in NetBSD 1.6.
