Can any one guide us where is the issue with my request. Header we are passing is like this - 6000376D25 Is passing message length is mandatory? How to pass the message length in the beginning of the hex dump if it is mandatory?

[mdzeyaullah]

@tilln Could you please help in this. I am a kind of stuck here in absence of sufficient information online.

[tilln]

Hi @mdzeyaullah

There could be several reasons that your message fails to process at the Bitmap field.
Any of the bytes sent before the Bitmap could cause the following bytes to be interpreted incorrectly.

1. Channel Class: Which one are you using and are you sure it's appropriate?
   Depending on the class, there may be other bytes sent before the actual message header, such as the message length and possibly other header bytes.
   Based on your logs it looks like your server expects some 12 bytes header information or it only reads 12 bytes based on the message length it received (or rather based on the bytes it interpreted as the message length).

2. Packager configuration: Have you got sufficient information to define Field Packager classes for all message fields?
   If a field is not packaged correctly, the server will misinterpret it, which could be the case for the MTI field or Bitmap as well.
   Make sure that the ASCII encoding of the MTI and Bitmap are appropriate.

3. Header data: Is the static header data you're sending correctly encoded? Is it supposed to be static (like a station ID etc)?
   Sometimes dynamic header data is required (that the underlying jPOS framework may be able to generate).

The Channel Class is the most important setting to get right, followed by the Packager configuration.

Unless you have good documentation I'm afraid you'll have to experiment with at least the above settings quite a bit.

What I would also recommend is to use a simpler message than your 1200 financial transaction message, but I'd start with an 1800 Echo request.
Perhaps the server side logging level could also be increased (to include debug information), so you can see what data is actually processed for those fields

22.01.12 21:44:20.589 [ blr:16449792]D-ISOHDL-0001: Process field: h1
22.01.12 21:44:20.589 [ blr:16449792]D-ISOHDL-0001: Process field: mti
22.01.12 21:44:20.589 [ blr:16449792]D-ISOHDL-0001: Process field: 0

[mdzeyaullah]

@tilln Thanks for the response.
I am working on echo message 1800. Will it be 1800 itself for iso 8583: 1993?
Do I need to share any other information to confirm the issue?
Is bitmap required to send in JMeter request or bitmap is generated by JMeter?
and what about header?
Could you please share one sample JMeter script for 1800?

[tilln]

@mdzeyaullah

You'll have to find out from your documentation, specification and/or server logs how to build your 1800 message.

As I doubt there is an issue with this plugin I don't think you need to share more information.

Bitmaps will be generated by JMeter, as documented.

As for headers, some Channel classes generate dynamic headers, for others you can specify static headers in the Connection Config or Sampler.

Here you'll find a sample echo message: .

[mdzeyaullah]

@tilln Thanks for your quick response.
Is there any way to add the message length and TPDU before the iso message in JMeter?

[tilln]

@mdzeyaullah
There are ways to do that, though why would you need to and not just let jPOS generate all that for you?
I'd suggest you try to find a Channel class that suits your needs. Otherwise you might have to implement your own, though I doubt that'll be necessary.

[mdzeyaullah]

The only challenge we have is to send the message length as 2 bytes before the message header.
I am using NACChannel in my request.

NACChannel | Talks with TCP based NACs Sends [LEN][TPDU][ISOMSG] (len=2 bytes network byte order)

[mdzeyaullah]

@tilln
Is MUX setting mandatory ?
I was going through this
https://github.com/tilln/jmeter-iso8583/blob/master/src/main/resources/nz/co/breakpoint/jmeter/iso8583/ISO8583ConfigResources.properties

Mux.displayName=Mux Settings
mtiMapping.displayName=MTI Mapping
mtiMapping.shortDescription=3 ten-digit numbers representing how the first 3 MTI digits are mapped between request and response
muxKeyConfig.displayName=Mux Key Configuration
muxKeyConfig.shortDescription=Each row contains the key fields for a message type as per the MTI column, or for all messages if the MTI column is empty
muxKeyConfig.tableHeaders=MTI|Key Fields

Ok, though other Channel classes do that as well. You'd have to experiment.
Hope that NACChannel is working for you now? Or are you still getting Bitmap errors?

@tilln Is MUX setting mandatory ? I was going through this https://github.com/tilln/jmeter-iso8583/blob/master/src/main/resources/nz/co/breakpoint/jmeter/iso8583/ISO8583ConfigResources.properties

Mux settings are optional (as per documentation).
Often times, it just works with the sensible jPOS default settings, otherwise you can do some tweaks there, e.g. when you're getting timeouts due to the Mux not being able to match incoming response messages to previously sent out request messages.

[mdzeyaullah]

Thanks @tilln for your response.

About NAC Channel: At least we are able to send the request to reach to the backend application server. Earlier it was rejected from the first interface like LB itself.
Is there different test packager for NAC Channel? As we see its different for base24 etc.

Actually, our data element 3 is getting the value of data element 4 at backend server and data element 4 is taking the value of next data element after 4 which is data element 7.
So it seems the application expects some more initial bytes before the actual message.
Still I am getting bitmap errors. Actually I am passing bitmap as 723007C128C28A05 but its converting to F23007C128C28A05 in hex dump generation.

As I experimented till now I am seeing that only through NAC Channel our request is able to reach till the backend server.
Perhaps I am repeating my question - where exactly In JMeter we can set the whole ISO message length if it can be handled by JMeter? Otherwise, how we will send the 2 byte message length before the ISO message if there is no place holder in JMeter.

I don't think you'll have to set the message length as this will be automatically calculated and sent by the Channel (see here and here).

Not sure what you mean, but what Channel you are using is pretty much independent of the Packager.
You'll have to define all message fields in your packager configuration file or find a suitable one from the samples included in jPOS.

Actually I am passing bitmap as 723007C128C28A05 but its converting to F23007C128C28A05 in hex dump generation.

It would be helpful if you could post some message and log details here, otherwise I'd just be guessing what could be off.

[chhil]

Please list the packager you are using, your initial message dump shows

<!-- org.jpos.iso.packager.GenericPackager[/] -->
You need to use a packager that matches what the receiver expects and not use the generic one.

e.g. My custom packager xyz.xml being used
<!-- org.jpos.iso.packager.GenericPackager[cfg/xyz.xml] -->

Still I am getting bitmap errors. Actually I am passing bitmap as 723007C128C28A05 but its converting to F23007C128C28A05 in hex dump generation.

Leading 72 from 723007C128C28A05 in binary is 0111 0010 [Fields 2,3,4,7 are present]
Leading FF from F23007C128C28A05 in binary is 1111 0010 [Field 1,2,3,4,7 are present

The field data follows your bitmap and are assigned based on the which ones are '1'/set
So in the case of F23007C128C28A05
what was field 2 is put in field 1 so on and so forth.

The problem is your packager file which you probably have not configured and the generic bitmap packing is causing it to get packed incorrectly.

I do hope you are not manually setting the bitmap and letting jpos packager do it for you.

All you need to do is set the fields (do not try and update the bitmap, it taken care of by jpos).
Use the correct channel. NACCChannel is working for you, and the receiver is unpacking the data so there is no need for TPDU etc.
Use the correct packager file with correct field level pckagers configured in it. Which seems to be a problem as the reciver is unpacking it based on how you packed it and the fields are off. So fix your packager.
