[U2] RE: U2 Users Digest V1 #2599
John, Be aware that sockets are a "stream" based protocol and not a "message" based protocol. When you send data to a socket it may arrive in one or more pieces (packets). On a LAN this may never occur, but over a WAN or the internet your data packets will almost surely be broken up into smaller pieces. On the receiving end you will need to know the length of the data you expect or have some sort of end-of-line character(s) to know when you have received all of the data. Years ago I wrote a program that worked well on a LAN, but failed randomly when data was passed through the internet. I mistakenly thought that if I sent a packet with 1024 bytes that I would always receive a packet with 1024 bytes (like writing and reading from disk). This is not the case. Kevin M.

RE: [U2] Does anybody have a hot backup server?
We have several customers, running UniVerse on Linux and Windows platforms, that use UV transaction logging to keep a backup server nearly current with their main server. We have scripted the copying of full log files to the backup server where another script rolls them into a copy of the main database (account). On pre 10.2 UniVerse, the backup server is within one full log (10 mb worth of transactions) with the main server (about 15-30 minutes). On a UniVerse 10.2 server, running on Windows, we have set the logs to "time out" after two minutes, so that the backup server is within two minutes of being current with the main server. The solution is well behaved and we have had it in place for the past few years. Kevin M. Sproule Sr. Technical Consultant AFS Technologies, Inc. 2141 E.

I am trying to put together a backup strategy that involves keeping a standby server within two data hours of the primary. The idea is to be able to have users log into the backup server and keep the business running in the event of a crash. I'd like to hear what solutions others have found for this. I've been trying to contact IBM for the last 6 months but they haven't answered and my ERP vendor doesn't know how to do this. Any ideas are appreciated.

David, Backup Exec has a default setting to backup open files "with" a lock. This will tend to terminate any UV processes that try to write to the files during the backup.

RE: [U2] UniVerse + PERL
Barry,
Win32::OLE is used to invoke UniObjects that are described in the
documentation within the UniDK. The connection does take a license and
the connection will fail if all licenses are in use. Always check
$uv->IsActive to see if the connection was made. For maximum
performance call UV subroutines instead of directly executing commands.
Eg.
...
my $subr = $uv->Subroutine('COMMAND.SUB', 2);
$subr->SetArg(0, "COUNT VOC");
$subr->Call; # call subroutine
if ($subr->Error) { print $subr->Error, "\n" }
$result = $subr->GetArg(1);
$result =~ tr/\376/\012/; # FM to LF
...
Where COMMAND.SUB "EXECUTEs" the first argument and returns the result
in the second.

RE: [U2] UniVerse + PERL
You can also use Win32::OLE to connect to UV. This script counts the
VOC:
#!/perl/bin/perl.exe -w
use Win32::OLE;
my ($err, $result, $cmd);
use constant UV_SESSION_OBJECT => 'UniObjects.unioaifctrl'; # name of
UniObject session object
$uv = Win32::OLE->new(UV_SESSION_OBJECT) or die "Cannot get session
object: $!\n";
$uv->LetProperty('UserName','kevin');
$uv->LetProperty('Password','password');
$uv->LetProperty('HostName','192.168.246.139');
$uv->LetProperty('AccountPath', 'KEVIN');
$uv->Connect; # open connection to sever
if (! $uv->IsActive) { # check status
print "Not Connected: $uv->{Error}\n";
exit;
}
print "Connected\n";
$cmd = 'COUNT VOC';
$uv->Command->LetProperty('Text', $cmd);
$uv->Command->Exec;
$err = $uv->Command->{'CommandStatus'};
print $uv->Command->{'Response'};
$uv->Disconnect; # close connection to server
