We are trying to make an ODBC connection via our intersystems ensemble (2016.2 running on ubuntu). However, when I am testing the connection I receive a pop-up that: "Http object response incomplete or invalid.0,#R". Note that the iodbctrace.log remains empty (and it is working because on the first try it registered a 459 error that I should activate kerberos, which I did). Any advise where I should look?
I have taken the following actions:
1. Expand the cacheodbc.ini in the mgr directory as follows:
Since version 2019.2, InterSystems IRIS has provided their Native API for Python as a high-performance data access method. The Native API allows you to directly interact with the native IRIS data structure.
Terminal says "Unable to open Registry key 'SOFTWARE\Microsoft\Windows\CurrentVersion\CommonFilesDir.1" when I execute $$Register^SNMP().
For monitoring purposes I want to use SNMP in Ensemble. One of the steps I have to do is to use the method $$Register^SNMP() in the terminal "%SYS" namespace. This is mentioned in a Intersystems Docs page.
The Widgets Direct sample application highlights many aspects of how to use InterSystems technologies to build a modern web application. Features include:
As web application gets more complex, more technologies are involved into the application development. Once it gets deployed in large scale the configuration gets more complex too. For sure one of the most difficult part of the story is the security. In a complex solution when independent servers are feeding single web pages with contents, it is indeed challenging to keep the integrity of such system. HTML5 introduced a (weak) security constraint, the Cross Origin Resource Sharing (CORS). This article tells how to enable CORS for CSP/ ZEN applications.
in order to do analysis on huge data volumes, it is better to take you data to a separate machine for analysis away from the operational machine, so trying to write huge globals or tables into files as is would take a huge space, what could be a solution or best practice ?..in python for instance, there is the pickling option (serializes data to byte string and saves it to a file) to save space, what could be best in object script ?
A few people wrote to me asking about the infrastructure behind the Atelier Server implementation. Its neat and a worthwhile story to share so I am writing it up here as a post on the community. I want to go in to a little detail on why it was needed and then I will outline in detail how we went about implementing this.
How can I create a JSON with the object ID by using the %Object:$toJSON API?
I have the following piece of code bellow where I create an object reference, create a %Object instance from %fromObject and them I am creating the JSON from $toJSON, but it does not expose the %ID (object id). How is the best approach to create a JSON with the respectives object IDs?
A unit of ObjectScript code (a ClassMethod, say) may produce a variety of unexpected side effects by interacting with parts of the system outside of its own scope and not properly cleaning up. As a non-exhaustive list, these include:
AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck. Here comes the question:
Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?
I'm working on exporting data from an Intersystems Cache database through the Cache ODBC Driver. There is a particular table that is giving me an error message. The ODBC Driver crashes and reports an error from the Cache system. I think I was able to trace down where the error is coming from, but I do not know how to debug or fix the error.
The table I am trying to extract is called SEDMIHP.
Finding errors in your code or examining unexpected behavior is the main purpose of Debugging I will try to refresh the traditional tools away from the helpers you have in Studio, VScode, Serenji, .... to the basics which have been there before your preferred EDI used it in the background.
I have a process which is passed a .rtf within a GlobalBinaryStream. I am trying to then output just the .rtf to a folder on a server, but not even sure where to start.
Is there a Built in Operation that I can pass the GlobalBinaryStream to which will then write the file to a folder, or do I need to use a custom class for the operation?
It's well-known that namespace global mapping helps us to write code independent on database storage details (Caché instance name, directory path). But sometimes we can face problems accessing an unsubscripted global which has subscript level mapping (SLM) defined. Most of such cases are evident and associated with administrative tasks that should be done on database level, but some of them can confuse even an experienced developer. Just to start:
Since this article is an overview of Flask Login, let's begin with Flask Introduction!
What is Flask?
In the realm of web development, Python has emerged as a formidable force, offering its versatility and robustness to create dynamic and scalable applications. For that reason, tools and services compatible with this language are in demand these days. Flask is a lightweight and easy-to-use web framework for Python. It stands out as a lightweight and user-friendly option. Its simplicity and flexibility have made it a popular choice for developers, particularly for creating smaller-scale applications. It is based on the Werkzeug toolkit and provides a simple but powerful API for building web applications. Unlike its full-stack counterparts, Flask provides a core set of features, focusing on URL routing, template rendering, and request handling. This minimalist approach makes Flask lightweight and easy to learn, allowing developers to build web applications quickly and without the burden of unnecessary complexity.
I realize that Cache Studio is the standard method to edit routines. However, some clients make it difficult to access their server that supports Studio. Is there an editor that can be run from the programmer prompt that allows simple WYSIWYG editing of routines? I know there is a %Routine class that you can use to do command-line editing, but I am looking for a full screen editor.
What was the standard in OpenVMS Cache before there was Cache Studio?
So another topic that has been of interest to a number of people since the beta was put up last week is in regard to Studio Hooks and Atelier. This requires a bit of background and then some discussion of how the architecture of Atelier necessitates some changes and then what our current thinking on the subject is.
A short post for now to answer a question that came up. In post two of this series I included graphs of performance data extracted from pButtons. I was asked off-line if there is a quicker way than cut/paste to extract metrics for mgstat etc from a pButtons .html file for easy charting in Excel.
I am fairly new to Ensemble and I wanted to know I have inbound business service (EnsLib.File.PassthroughService) which is looking for pdf files once it finds a pdf file (within the business process) it needs to find the associated xml file which would be in the same directory. Once both of these files are found they need to be sent to the business operation and deleted from the source (EnsLib.File.PassthroughOperation).
