Profiling code using Caché Monitor

Not everyone knows that InterSystems Caché has a built-in tool for code profiling called Caché Monitor.

Its main purpose (obviously) is the collection of statistics for programs running in Caché. It can provide statistics by program, as well as detailed Line-by-Line statistics for each program.

Using Caché Monitor

Let’s take a look at a potential use case for Caché Monitor and its key features. So, in order to start the profiler, you need to go to the terminal and switch to the namespace that you want to monitor, then launch the %SYS.MONLBL system routine:

NOTE: This content was originally presented at the InterSystems Global Summit in 2014, however related topics often come up on the Developer Community so I have decided to turn this into an article for easier reference and discussion. However, much of the content was pulled directly from the presentation slides so the article format resembles that of a PPT deck more than paragraphs.

I am trying to determine the write-access to a windows-directory, using the method %File.Writeable(). But, this method always returns the boolean "true", even when I have revoked the write-access of Healthshare-user in this directory.

Note:
1) When the same ensemble-service tries to write a file in this directory (which it says is "writeable"), it fails.
2) The method %File.Writeable(...) works perfectly in the case of files.

Any help is appreciated.
Thanks in advance... :-)

Monitoring with Zabbix

Hi community,

I need to monitor Caché Intersystems with some custom indicators.

I started customizing the SNMP Mib. But I've been in a Zabbix event, all speakers use ODBC to monitor their database, Oracle, MySQL, PostgreSQL ...

What is the best way? Use ODBC or SNMP Custom Mib?
What are you guys using?

Using the following...

//Get PDF stream object previously saved
   Set pdfStreamContainer = ##Class(Ens.StreamContainer).%OpenId(context.StreamContainerID)
   Try {
     Set pdfStreamObj = pdfStreamContainer.StreamGet()
   }
   Catch {
      $$$TRACE("Error opening stream object ID = "_context.StreamContainerID)
      Quit
   }

Would it be possible to search the pdfStreamObj for certain values like a Medical Record, or Patient Name?

Thanks

Scott

Introduction

InterSystems would like to optimize IRIS to take advantage of modern CPU instruction set extensions. That’s great for product performance, but how do you know if your CPU will still be supported for new IRIS builds? Here’s how to know your CPU’s microarchitecture family as well as how to find out your CPU’s specific instruction set extensions.

I'm trying to execute a nodejs process to perform some work on a string from Cache/Mumps over to nodejs, then return the result from nodejs as a string back to the code in Cache and I was looking at the `$ZF` logic - it will let me output the results to a file (i.e. temp.txt) but I dont see a way to just get the output set back to an M variable like (and I know this is not the correct syntax, but just for example)

S myOutput=$ZF(-100, "echo something") ;; wrong syntax but just for example

W myOutput ;; want to write out "something" but of course this doenst work

Good morning everybody,

In Html sometimes we need to use entities code for don't have problems with browsers all over the world. Ex. 'á' is converted to code: 'á' / 'é' is converted to 'é'.

I have a question, how can i convert a string like my name to this type of code? Ex. "Flávio" will be "Flávio". I tried this way:

A request came from a customer to estimate how long it would take to encrypt a database with cvencrypt utility.

This question is a little bit like how long is a piece of string — it depends. But its an interesting question. The answer primarily depends on the performance of CPU and storage on the target platform the customer is using, so the answer is more about coming up with a simple methodology that can be used to benchmark the CPU and storage while running cvencrypt.

Hi,

somehow my installation on win10 canceled during finish. "Installation of Caché finished" showed up for 20 minutes and canceled with an error I didn't saved.

Every file and service was installed but never registered as successfull installation. Now I try to reinstall it but the installer shows me everytime "Another installation is already in progress. Please finish the second installation first".

The unfinished installation is broken. I can't startup Caché from launcher. So I deleted everything in c:/intersystems

Things I already tried:

Some weeks ago, I was reading a book by Stephen Hawking and Leonard Mlodinow, The Grand Design. At a certain point, trying to define why do we exist? , why do we use the models we use in physics?, ...those kind of things you know... they pointed at the Game of Life example invented by the mathematician John Coward in 1970... Basically he wanted to show that a system with really basic fundamental laws (Physics) could evolve and "live" to become a more complex system (Chemistry) in which "something" (humans) could work out its own model and complex rules to explain its reality… the rules for this deterministic model that he exposed were so basic that I thought it could be funny to implement them in ObjectScript when I had some spare time... there are others implementations in JavaScript and other languages... but not in ObjectScript... and that had to be corrected!!… so here you are!

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.

Hello,

This package may be of interest...

Link: https://github.com/litesolutions/cachedb-import

I have programmed this over a hunch, in order to facilitate the retrieval of source code from a Caché installation. It makes use of the Java API provided by Caché.

Right now, I use it as a means to salvage sources in order to analyze them using the SonarQube plugin I develop for my employer. Unfortunately this plugin is not open source.

I am calling for help here, on two fronts:

We are updating a C# module which creates consumes an OdbcConnection from System.Data.Odbc. This module used to create a DSN-less connection through the InterSystems Cache driver, and we are updating it to call the IRIS ODBC35 driver following migration of the target database.

The Cache connection was formed formatted as follows:

Easy CSV TO FHIR - InterSystems Contest

Hello everyone, I’m a French student in academical exchange for my fifth year of engineering school and here is my participation in the FHIR for Women's Health contest.

This project is supposed to be seen as the backend of a bigger application. It can be plugged into a Front End app and help you gather information from your patients. It will read your data in local and use a Data Transformation to make it into a FHIR object before sending it to the included local FHIR server.
