Limits in AcuXbis for Extend

Jump to solution

We have been using xBIS on Windows for Extend 9 for some time.  We're implementing a new method which requiring uploading quite a bit of array data.  A curious thing happens - if the content length is 49152 bytes or less, the BIS Content section is populated and everything works fine.
HTTP_CONTENT_LENGTH:49153
HTTP_CONTENT_TYPE:text/xml;charset=UTF-8
HTTP_ACCEPT_ENCODING:gzip,deflate
HTTP_HOST:optics2012
HTTP_USER_AGENT:Apache-HttpClient/4.1.1 (java 1.5)

With the exact same schema, but different data such that the content length is 49153 or greater, the BIS Content section is EMPTY, and obviously the method fails.

It seems there is a limit of 49152 imposed somewhere, but we can't find an entry in IIS anywhere.

Does this sound familiar to anyone and if there is a limit, is it imposed by BIS or can it be relaxed?

Thanks

Tony

Hi Tony: Extend version 9 and 10 installations will co-exist on the same machine. Version 10 will not replace version 9.  You can test your ACU XBIS installations side-by-side by using different virtual directory names, or  you can use the v10 BISMKAPP utility to redirect your XBIS 9.1 virtual directory so it's served by XBIS 10 and ACU 10.

The new BISMKAPP configuration tool supersedes BISMKDIR and doesn't require IIS 6 configuration compatibility.

I have seen limitations in the RM version, and I think it was a configurable limitation imposed by IIS.  But it has been a long time, so I don't really remember well.

Hi Tony:

Which version of BIS for Extend are you running?

A problem like this was reported against BIS for Extend version 9.1 and was fixed in 9.2. The problem report ID was RPI1088336.

For XML requests, the internal XML HTTP reader reads 48kb chunks and there was a boundary problem in the Windows version of BIS in 9.1. v9.2 was tested with payloads many megabytes in size, so this really sounds like the problem you are seeing.  Also, the diagnostics for malformed requests were greatly improved as part of the fix.

We are running version 9.1.2, so it seems this might, indeed, be the problem.  We do have the version 10 license but I was reluctant to upgrade (since everything was working, prior to this).

To upgrade from xBIS 9.1.2 to xBIS 10, do I need to un-install xBIS 9.1.2 first, or will installing version 10 automatically update 9.1.2?

Thanks, Uwe.  Installing 9.2 fixed the problem.  We'll look at installing to version 10 as time permits.
