ipcBeginProcess Error Please help. thanks!

I executed a command in a remote host using ipcBeginProcess just like
as shown below

cid = ipcBeginProcess( "date" "myhost" "" )

then I checked the value of cid:

cid
ipc:0

Since the value of cid is ipc:0 I think it means that the process is
already alive.

BUT there was an error message in the Konsole (command line) where I
have executed the

"icfb &" command.

it says "cdsServIpc: Command not found."

What could be possibly wrong? Permissions? Cadence Set-up?

Thank in advance!

Hi,

There is a bit of explanation from the Cadence's doc:
Interprocess Communication SKILL Functions Reference ($CDSHOME/doc/
skipcref/kipcref.pdf)

For SKILL-IPC to start a remote process, it must be able to locate the
cdsServIpc program
on the remote host. This is typically done by using the same filepath
to the Cadence
installation hierarchy on both the local and remote machines.
......

In other words, Cadence needs the 'cdsServIpc' unix executable to run
the ipcFunctions. So according to your error message, cdsServIpc is
not recongnised and that's the reason why your commands are not
running.

I would propose the following:
1. look where your cdsServIpc unix executable is installed by using
the unix 'which' command
2. make this 'cdsServIpc' available by default in your environment,
either by:
+ making an alias
+ making a link into an area which is part of your default PATH env
var
+ make by a little shell script (csh, bash or whatever depends on your
default shell)
Thus purpose of this is to make 'cdsServIpc' available by default in
your env.

Back to your CIW and run the IPC again,

Hope this help you in beating this issues !

Riad,

thank you very much.

I tried your third recommendation.

And the "cdsServIpc: Command not found." did not appear anymore but
there was no result either. (T_T)

The cid parameter just kept a value of ipc:0....

I tried to add the last parameter (log file) of ipcBeginProcess but it
was not created.

I have read an article in one of the Cadence Manuals found under the
link below:

http://www.d.umn.edu/~htang/Cadence_doc/anasimhelp.pdf

Basic Requirements for Running a Remote Simulation


The directory on the host where the Analog Design Environment is
running should have
the exact file system path on the remote host also.


Users should be able to perform an rsh on the remote host without
any login/password.


Once rsh is successful, the login SHELL run command file (.cshrc for
CSH) should
contain appropriate path settings for the Cadence hierarchy. This
implies that all the
executablesshould be in path and LICENCE is set to the appropriate
licence server.


The cdsServIpc process should be running on the local as well remote
hosts.

In the third requirement, it says that the cdsServIpc process should
be running on local as well remote hosts.

I think the thrid requirement is what I need...

How can I invoke the cdsServIpc in my remote host or in my local host?

thanks and best regards,

Riad,

by the way, the command that I am executing is a batch file.

I have change the permission of the batch to make it executable using
chmod 755.

There is no problem when I execute ipcBeginProcess( "mybatchfile" ""
"" ) locally.

By the way about this:

Command: ipcBeginProcess( "mybatchfile" "myremotehost" nil nil nil
"test.log" )

I have found the the log file in the home directory in the remote
host, but it was empty.

thanks in advance!

 

Can you please try the following:

1. Rename your shell script into 'cdsServIpc' and add some env
settings to make cadence alive. I would propose the following bourne
shell file :

#!/bin/sh
DFIIHOME="YOUR_CDS_HOME_PATH"
export DFIIHOME
CDS_LIC_FILE="port@serverort@server ..."
export CDS_LIC_FILE
PATH="$DFIIHOME/tools/bin:$DFIIHOME/tools/dfII/bin:$PATH"
export PATH
$DFIIHOME/tools/dfII/bin/cdsServIpc $*
# end of script

This little script should set up the environment for Cadence
(executable + license) and then executes the cdsServIpc with whatever
arguments it is given to.

This script Is off the top of my head since I'm not online to check
it ... sorry :-(
I hope this will help.

Riad.
