Only 1 Label Printed When Sending 2 By Http フォローする

Hello,

we have setup an TCP/IP-port in Commander for listening. When sending 2 XML requests at the same time to this port, only one of the requests is printed. For testing I have sent the 2 requests with same data (same printer and label content). If we send the second request with some seconds waiting, it works. The response of the failed one looks like this:

<?xml version="1.0" encoding="utf-16"?>
<Response Version="2.0" Name="ZEQUIPRT01_XML" ID="111" AppName="BarTender" AppVersion="9.3 SR2" AppVersionId="930" AppVersionMajor="9" AppVersionMinor="30" AppVersionBuild="2725" AppInstancePid="3324" AppInstanceGuid="{455B39BD-41BC-48EB-AE0B-A78BDCB3950E}">

<TotalLabels>0</TotalLabels>

</Summary>
<Pages TotalLabels="0" TotalPages="0"/>
</PrintData>
<Message Id="2609" Guid="{04E7BA5F-7479-4E54-AC3D-D16F8B6529AC}" Severity="Warning" Category="Miscellaneous" Response="OK">
<Text>Es konnte kein leeres Etikettenformat erstellt werden.</Text>
</Message>
</Print>
</Command>
</Response>


Error Text is german and means something like "cannot create emtpy label format". What does this mean? Any ideas how to solve this problem?

Regards
Markus

Out of interest, if you configure the BarTender command handler to run more than one BarTender process do you still get this issue?

We have configured 5 BarTender processes. Sometimes I don't even get any btxml response back (means written as file to disk) for one of the two requests. I have 2 requests which I write to disk, then transformation happens and content is written after transformation to file. Until now everything looks good for both requests. I always get one correct response and printed label, for the second request I sometimes get an answer like in the first post and sometimes I don't see any response file.

What trigger detection parameters have you specified for constituting a trigger event?

Do you send both triggers in a single network connection, one after the other, or do you create a new connection for each trigger? Please give details.

I have attached a screenshot of trigger and command settings. I get two input files like this, I assume it's two seperate connections:

POST / HTTP/1.0
content-type: text/xml; charset=utf-8
content-length: 778
user-agent: SAP Web Application Server (1.0;701)
host: 172.xx.xx.xx:8001
accept-encoding: gzip
sap-language: D

<?xml version="1.0" encoding="UTF-8"?><ZEQUIPRT01><IDOC BEGIN="1"><EDI_DC40 SEGMENT="1"><TABNAM>EDI_DC40</TABNAM>.......</IDOC></ZEQUIPRT01>

I first remove the HTTP header with Search and Replace command, so only XML content remains. This is transformed to btXML.

Seems like I found the reason for the problem. Because I couldn't reproduce the error on a local installation on my pc, I checked the differences and only noticed in Commander that there have been open connections for the TCP/IP port which did not seem to close automatically. After restarting the Commander Service it seems to work now. What I do not understand is why some connections are not aborted by Commander because I set a timeout for the port of 60000 milliseconds. And why open connections disturbe the processing of btxml in bartender process because input files and transformation output always worked for both requests correctly?
