Oracle is running on one of the zone (out of 17 non-global zones) and it is supposed to use 1 core only, but looks like it is not configured correct. Below is the output from global as well as zone
What is significance of limit=1 in this output from zonecfg ?
Only one zone is having limit=2 and rest all 16 zones are having limit=1. Will it not be restrcing cores anbd Oracle should see and charged only for one core ?
I wrote a very simple script that matches combinations of alphabetic characters (1-5). I want to use it to test CPU speeds of different hardware/platforms. The problem is that on multi-core/processor systems, only one CPU is being utilized to execute the script. Is there a way to change that?... (16 Replies)

Hi folks,
I want to know how to run two unix programs on two different cpu cores on a 2-core or 4-core or 8-core CPU machine? Extending this how would i run four and eight unix programs on 4-core and 8-core machine respectively?
If this can be done, how to know which program is assigned to... (1 Reply)
Hi Experts,
I am executing multiple instances(in parallel) of perl script on HP-UX box.
OS is allocating substantial amount of CPU to these perl processes,resulting higher cpu utilization.

lx - Linux branded zone
DESCRIPTION
The lx brand uses the branded zones framework described in brands(5) to enable Linux binary applications to run unmodified on a machine
with a Solaris Operating System kernel.
The lx brand includes the tools necessary to install a CentOS 3.x or Red Hat Enterprise Linux 3.x distribution inside a non-global zone.
The brand supports the execution of 32-bit Linux applications on x86/x64 machines running the Solaris system in either 32-bit or 64-bit
mode.
Supported Linux Distributions
The lx brand emulates the system call interfaces provided by the Linux 2.4.21 kernel, as modified by Red Hat in the RHEL 3.x distributions.
This kernel provides the system call interfaces consumed by the glibc version 2.3.2 released by Red Hat.
In addition, the lx brand partially emulates the Linux /dev and /proc interfaces.
Configuration and Administration
The lx brand supports the whole root non-global zone model. All of the required linux packages are installed into the private file systems
of the zone.
The zonecfg(1M) utility is used to configure an lx branded zone. Once a branded zone has been installed, that zone's brand cannot be
changed or removed. The zoneadm(1M) utility is used to report the zone's brand type and administer the zone. The zlogin(1) utility is used
to log in to the zone.
Application Support
The lx zone only supports user-level Linux applications. You cannot use Linux device drivers, Linux kernel modules, or Linux file systems
from inside an lx zone.
You cannot add any non-standard Solaris devices to a Linux zone. Any attempt to do so will result in a zone that zonecfg(1M) will refuse to
verify.
You cannot run Solaris applications inside an lx zone. Solaris debugging tools such as DTrace (see dtrace(1M)) and mdb (see mdb(1)) can be
applied to Linux processes executing inside the zone, but the tools themselves must be running in the global zone. Any core files generated
are produced in the Solaris format, and such files can only be debugged with Solaris tools.
