To show real time status of file list deployment

jpm

I am deploying files list through OpenDeployNG.
While executing the iwodstart command for filelist deployment i have requirement to show the user a page with running status and finally confirmation page .

presently i am working with the logic

$od_running = `/opt/iw-home/OpenDeployNG/bin/iwodserverstatus`;
if ($od_running =~ /OpenDeploy server is alive/)
{
print "The deployment process is underway.";

my $variables = "target=$targetWorkarea&status=$running_flag&userId=$userId&hostname=$hostname&vpath=$vpath";

# first time through refresh
print "<meta http-equiv="\"refresh\"" content="\"12;" url="http://$hostname/iw-bin/DeployAcknowledge.ipl?$variables\"" />";
#same page is called in loop
}
else
{
print "

OpenDeploy is not running

";
}


but the refresh functionality and real time status is not coming.

Real time status is unlikely to be easy, if possible at all (perhaps with CSSDK or SOAP?) as the OpenDeploy CLT does provide such feedback in that manner.
You could, potentially, figure out what the micro-log file is named for the specific deployment and open it to perform a programmatic "tail" on it - but it will still not be truly "real time" as the output is buffered (first by OpenDeploy, second by your UI - though you can minimize that usually) - but you'd also have to run the deployment process in a forked or asynchronous manner so that your script can continue to read from the log file while the command is running (generally speaking the OpenDeploy CLT doesn't return until the deployment is completed - successfully or otherwise)

The final confirmation is relatively easy (certainly in comparison) since you wait until the process is complete and then check the exit status (note: you should really be using iwodcmd start and not iwodstart) - this has been posted a number of times but the basic code is:

...
my $cmd = qq($odhome/bin/iwodcmd start $odcfg $params);
# $odcfg is the name of the deployment configuration file
# $params is things like: -k "foo=bar" -inst unique-string
my $results = qx($cmd 2>&1);
if ($?) {
    # error occurred - strip padding from exit status
    my $status = $? >> 8;
    if ($status == 1) { ... } # unable to start
    elsif ($status == 2) { ... } # failed while running
    elsif ($status == 9) { ... } # completed with errors
    else { ... } # unrecognized exit status
}
else {
    # success
}
