My situation is :
I have used netClusterGet first with some cluster size(size A), now
that I have to store more addresses which may not fit in current
cluster size which we have got for first time, So I want to increase

Hi PAD,
We are building the ROM resident vxworks 6.6 image to run the vxWorks

be in SD-RAM.
i.e The text section of an object file (eg:test.o) will be in Flash
and data section in SD-RAM.
Now i want to create an addtional file (sample.c) and copy the text

recvfrom socket system call does not return anything for initial 3-4 minutes and then works fine.

khandekar.tuka...@gmail.com (Tuks) — Mon, 21 Dec 2009 07:35:50 UT

Hello All,
There is simple client server application running in my product.
There is a UDP socket opened with the server and my product sends a
packet successfully to the server.
Then it is blocked on the recvfrom call for receiving the data.
But, for initial 3-4 minutes, this recvfrom call does not return

How to invoke webservices on VxWorks? Is gSoap library the best option?

sharadjoshi.bengal...@gmail.com (Sharad) — Wed, 16 Dec 2009 08:53:14 UT

Hi,
I need to invoke web services on VxWorks. I am currently exploring
gSoap libraries for the same. Has anyone used gSoap library for web
services on VxWorks? Is gSoap the best option? Is there any other
library for this.
Please advice.
Thanks in advance.
Warm Regards,
Sharad

If you are develop on Workbench IDE Tool. you can find easily
component configuration window.
but if you work in command , edit in config.h file

Yes, the worker queue is maintained by the kernel. The size of the
work queue can be configured when you build your project.
The idea behind the work queue concept works because "statistically"
execution flow is seldom interrupted during kernel state AND most ISRs
do not need to make many kernel calls (if any). The more interrupts

Thank you very much for your reply . Can you please do me favor and
let me know where are the kernel configuration components ?

Sparky,
So do you mean that the worker queue is maintained by the kernel?
And will this behaviour be deterministic, ie., assume in one case
there ISR
went thru and took a kernel lock( because there was none initially)
Versus
another case where there is a kernel lock causing the worker queue to
kick in.

Bill/Peter
Thanks for your feedback, that's a great help.
We're running VxWorks 6.6 on an MPC8548 CPU. So I'm guessing that means
<kernelState> is likely set to FALSE for "Idle".

On older versions of VxWorks, the system used to idle with the
<kernelState> set to TRUE. Somewhere around VxWorks 6.0 I think that
changed so that the system would idle with <kernelState> set to
FALSE. Thus, if your VxWorks version is old enough, it is conceivable

You didn't tell us what version of VxWorks (or Workbench) that you're
using. You didn't tell us what CPU arch you're using either.
I'm not positive, but I don't think "kernel state" is a task: it
refers to the amount of time the CPU spends executing VxWorks kernel
related code -- that is, code that involves handling the scheduling of

Hi all
Does anybody know anything about the Wind River Workbench Performance
Profiler output?
In particular there is a task in the System Viewer results called "Kernel
State" which is not elaborated upon that is taking up around 20% of our CPU
time. What is this task? Can we reduce its impact on the results? Is this
