The last time that I created a playground for experimenting with machine learning using Apache Spark and an InterSystems data platform, see Machine Learning with Spark and Caché, I installed and configured everything directly on my laptop: Caché, Python, Apache Spark, Java, some Hadoop libraries, to name a few. It required some effort, but eventually it worked.
Here I’ll walk you through the process of creating a simple Node/Express API and connect it to a InterSystems IRIS instance.
I won't go into much detail about how to work with any of the technologies I will mention in this tutorial but I will leave links, in case you want to learn more.
The objective here is to give you a practical guide on how to set up and connect a node.js back-end API to IRIS.
Before we get our hands dirty, make sure you have Node.js running on your machine. So I'll check:
Can anyone suggest suitable Cache ObjectScript syntax for open/use/read statements on a simple ms-dos text file. I've tried various examples seen on the web but they appear to be implementation specific. I used MSM MUMPS many years ago but am now retired & would like to write a few simple routines for my own amusement & mental challenge. I am using the free Version of Cache (V 2017.1) on my Windows 10 PC. The installation file was CachePCkit_x64.exe My apologies for this query being very basic.
I have a batch record mapper that reads a csv file and passes the message to a process that uses the EnsLib.MsgRouter.RoutingEngine and would like to pass the message to an operation that will output that as a XML file but so far been unlucky as the operation that I use , uses the EnsLib.EDI.XML.Operation.FileOperation which only works with the messages("BusinessOperation class for writing XML messages to a file.
I'd like to have production specific settings for different environments (OTAP). I have set the system default settings on my production to override the default settings. However, this does not seem to work. It is my understanding that the system default settings override the settings I have set on the production (I thought I heard my Sales Engineer say this). However, reading the documentation I am not sure of this reading either. However, when I clear the values for the adapters on my production my system default settings are still not apply.
I'm trying to set Caché-Python Binding on Mac, but there is a problem.
I performed installation and configuration of Caché-Python binding module based on the manual (URL) including setting of PATH and LD_LIBRARY_PATH in "bash_profile", and they seems to be done successfully (there was no error in the process).
I am using the EnsLib.RecordMap.Operation.BatchFileOperation to write a batch to a file but for some reason this has been working fine as of yesterday I had a problem with the cache databases filling up running out of memory so had to compact my database and gain space now when I run the operation I get the above error .Of course in my batch table there is no batch record with ID 1.The message is passed with the correct header information but still get this error any suggestions why?
This is a beginner’s guide to the design of a “MicroService” implemented in Ensemble. “MicroService” is a popular phrase these days which has a broad interpretation. My interpretation is: “MicroService” is a “NoSQL Service”. A what? The answer is in the article.
We learnt what the difference is between SQL and NoSQL databases. For me the difference is nearly the same between a SOA Web Service and a “MicroService”. I am going to explain it through an example.
Ok so I am way outside of my comfort zone, and had to build an application using CSP to give users the ability to access SQL configuration tables. These SQL Configuration tables will affect the data that is sent to the downstream system.
I saw in the examples where we were able to import GIF's/IMAGES into the CSP folders to use as a reference in our CSP pages. My question is how do you do that? If I try to import through studio, it tells me the file is invalid.
Just trying to make it a little more user friendly then blocks on a page.
Here you have an easy way to write and execute COS code from your unix scripts. This way one does not need to write routines or even open Studio or Atelier. It can be an option for simple and small actions for instance things like installation tasks or compiling.
See sample bash script (compile.sh) to compile classes:
I have very recently started to work with Ensemble and have both the 2014 and the 2017 version.
To learn, I have created a small test flow that takes an xml file using EnsLib.EDI.XML.Service.FileService, sends it to a Process that transforms it with xslt into another format, and then passes it onwards to a EnsLib.EDI.XML.Operation.FileOperation Business Operation.
This is the code that I have before and when sending it onwards:
I am a brank new cache developer. I am trying to create a new server, such as Samples, in the Studio and create a new namespace under the server, how do I do that?
Trying to evaluate it and work out how we could use it.
As a standard application database. Object or relational etc. does not matter.
Issue is ObjectScript.
So:
1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?
A beginner’s guide to position Ensemble in regards to MicroServices Architecture (MSA). MSA is getting more visibility in the Enterprise Java world therefore it is vital to understand what is behind the buzz. I make a (humble) attempt to write my view and share with you.
With a routine like this one, you can quickly calculate how many lines of code you are working with. And it is not only for routines, it works for classes because remember that classes generate routines !
InterSystems IRIS has a menu called Interoperability.
It provides mechanisms to easily create system integrations (adapters, record maps, BPMs, data conversions, etc.) so different systems can be easily connected.
I have a service that takes a file and pass it through to the production .While I am passing the file through I get the file stream and set it to a variable within my message and the variable is of type %Ens.StreamContainer. But after all processing and I need to write out my file to a pdf format The file gets written but is a corrupt file since I can not read it I have tried this with asimple pass through everything is fine .But here I do not know what I am doing wrong here is the operation code
Has anyone found an Eclipse plug-in that provides the capability to connect to a Caché server and give the user a way to write SQL queries using the tables from that server? I'm picturing something like a "WinSQL"-client built as an Eclipse plugin.
I've found and tried the following, but I couldn't get it to connect to my local Caché instance.
Hi.. I have an issue where we are using OAuth2.0 with the ZAUTHENTICATE routine. Once our token is validated we are using a users lan id (passed on the ID token) to find a software defined username in a Cache Global.
That is all working fine in ZAUTHENTICATE.. I am setting the software defined username in the Properties("Comment") array and wanting to reference it in the Rest Service Dispatch class.
