iwmigrate.exe has stopped working

Hi all,

I have been working on a Perl script to migrate Branches, Workareas plus last Editions. On testing the script in a virtual machine iwmigrate.exe periodically crashes (sometimes after every recursive call to iwmigrate) and a windows error dialogue box appears asking to close the program.

From what I can see this doesn't appear to have an effect on the success of the last branch migration but I can't be 100% sure.

I wondered if anyone could advise as to why this might be happening and what I can do to resolve the issue?

Thanks in advance,

Adrian.

I have been working on a Perl script to migrate Branches, Workareas plus last Editions.

It might help to know some more of the particulars (see this) and perhaps the script or at least the iwmigrate command lines used.

Also - what do you mean by "migrate Branches, Workareas, plus last Editions"?
If you migrate a branch - chances are you already have migrated the last edition.

Thanks for the response.

The version of TeamSite I am using is 7.3.2 on Windows server 2008.

Below are excerpts from the script.

For each Branch in the branches array I'm getting the latest Edition (we want to migrate this Edition only) and then using the iwmigrate CLT with the following flags to migrate the Branch plus latest Edition only, and any Workareas in that Branch:

iwmigrate -g -m -o -b -s -d -w

[PHP]
for(@branches){
$branchCount++;
my $branch = $_;

# remove default so that we can run against iwlasted clt
my $subBranch = substr $branch, index($branch, 'main');
# Get latest Branch Edition
chomp($lasted = `iwlasted \"$subBranch\"`);

print "\nBranch is: $branch\n";
print "latest Edition: $lasted\n";
print "\subBranch is: $subBranch\n";

# if there are no editions then just migrate branch and workarea
if($lasted eq "INITIAL"){
executeCmd($branch,"iwmigrate -g -m $mount -o \"$newStore\" -b \"$branch\" -d -w >> $logdir 2>>$errdir");
} else{
# else migrate branch, latest edition and workarea
executeCmd($branch,"iwmigrate -g -m $mount -o \"$newStore\" -b \"$branch\" -s $lasted -d -w >> $logdir 2>>$errdir");
}
}
[/PHP]

[PHP]
sub executeCmd{
my($branch1,$cmd) = ($_[0], $_[1]);
#print "branch is: $branch1\n";
print "command is: $cmd\n";
my $result = `$cmd`;
}
[/PHP]

Are you collecting the output of iwmigrate ? When it fails, you need to restart it with a different invocation. Most likely you need to run it from a shell to fix.

I don't have time, nor the inclination, to spend too much time trying to figure out / debug your code, but I'll make some suggestions, I suggest you compare this with the code you posted (it's based on that, but significantly cleaner based on what you showed):


 foreach my $branch (@branches){
  # Get latest Branch Edition
  chomp(my $lasted = qx($iwhome/bin/iwlasted "$branch" 2>&1));   

  print "\nBranch is: $branch\n";
   print "latest Edition: $lasted\n";
  # if there are no editions then just migrate branch and workarea
   my $sarg = ($lasted =~ /^\s*$/) ? "" : qq(-s "$lasted");

   executeCmd($branch, qq(iwmigrate -g -m $mount -o "$newStore" -b "$branch" $sarg -d));
  executeCmd($branch, qq(iwmigrate -g -m $mount -o "$newStore" -b "$branch" -d -w -only));
 }

sub executeCmd{
 my($branch1,$cmd) = @_;
 warn "command is: $cmd\n";
 my $result = qx($cmd >> $logdir 2>>$errdir);
        my $status = $? >> 8;
 warn "result is [$status]: $result\n";
}

Hi Nipper. I am redirecting both stdout and stderr to individual logfiles. The iwmigration.exe crashes but this seems be after a branch has successfully migrated as there are only success messages logged in the log files.

Thank you very much for your recommendations I will study the changes and test. I will update the thread with the results when I have done so.

Adrian.

Thanks very much for your help Ghoti - since implementing your suggestions the problem has not come back.

Thanks & Regards,

Adrian.
