UNC path not recognized

Hi Guys,

One of our clients is running Cache 2014.1.4 and for some reason is not recognising UNC paths?

The Path is accessible via windows explorer with no issues (\\backupsvr) and also my works fine when using :

O C:\folder\file.txt:("WNS"):5

Edit your Globals with VSCode and YAML

The best way to list, edit, save and delete globals is using an IDE. Now, it is possible if you use VSCode. It is also possible to save globals using yaml files. Perform the following steps:

1. Get an InterSystems IRIS instance and install the application iris-global-yaml: 

zpm:USER>install iris-global-yaml

2. If you just to want an InterSystems IRIS trial for tests git clone and run on docker:

OCR and NLP together into InterSystems IRIS

According to IDC, more than 80% of information it is NoSQL, especially text into documents. When the digital services or applications not process all this information, the business lose. To face this challenge, it is possible use OCR technology. OCR uses machine learning and/or trained image patterns to transform image pixels into text. This is important, because many documents are scanned into images inside PDF, or many documents contains images with text inside. So OCR are an important step to get all possible data from a document.

This quick guide shows how to serve HTTPS requests with InterSystems API Management. Advantage here is that you have your certs on one separated server and you don't need to configure each backend web-server separately.

Here's how:

1. Buy the domain name.

2. Adjust DNS records from your domain to the IAM IP address.

3. Generate HTTPS certificate and private key. I use Let's Encrypt - it's free.

4. Start IAM if you didn't already.

5. Send this request to IAM:

Hi, Community Members!

The goal why we are posting questions on Developer Community is to get the answer.

Here is very simple guidelines document on how to ask questions which would get answers.

When you post a question you need to feel 3 fields: title, body, and group. And tags.

1. The Title

A good title should contain the brief description of your problem - it should not be longer than 80-90 symbols.

But brief doesn't mean one word. These are not very good titles for questions: Cache, Ensemble, Peace, World.

Hi,

I'm posting this for the benefit of others. Not often one changes certificates in Cache, at least in my case. I run a system, that uses certificates to encrypt SOAP messages, and since the last time I ran it, my certificates expired.

So I renewed them using our PKI tool, so far so good. I gave all (3) certificates the same names (and filenames too) as to those expired, thinking that everything would just work fine next time I call the SOAP service.

Unfortunately, I got trapped.

Git plugin for Cache Studio

Has anyone recently deployed the cache-git-studio plugin from Github repo?

In particular, I see that this plugin is installed at the namespace level, so it appears for each user have their commits in their own name, they must all be running a locally installed cache server when doing their dev work. I suspect that is the preferred way.

In my organization they are currently just accessing a remote cache server from Studio. In that scenario, it looks like it would be one installation of git for the whole team. and thus only one shared git user.

Hi guys!

Portrait of Madame X, Gustave Caillebotte.

One of the features I like in InterSystems ObjectScript is how you can process array transformations in a specific method or a function.

Usually when we say "process an array" we assume a very straightforward algorithm which loops through an array and does something with its entries upon a certain rule.

The trick is how you transfer an array to work with into a function.

One of the nice approaches on how to pass the information about an array is using $Name and Indirection operator.

Below you can find a very simple example which illustrates the thing.

Dear Colleagues,

Recently I am working on a Cache project should enable the customer, to update our Cache application independently from us. Our idea is a client (preferred .net) application that will copy all the necessary Cache stuff (classes, routines) into a cache database. For this, we are looking for the appropriate technology – in old times this would be a CacheDirect.

Hello,

It is time for me to eat my own dog's food and start implementing unit test running with coverage :) I will be inundating IRC with questions at this point, but I have a more general question first.

In this tutorial, it is supposed that your unit tests are exported as XML first... But that's not very practical. Is there a way, instead, to run all tests from a given project without having this export?

My first thought on how to do this would be to:

Code Golf - Encoder

We need to send some coordinates to a spaceship through a laser beam.
To do that we have to encode it, and beam it out into space.
Your mission is to implement the encoder with a compression standard.
As usual shortest solution wins.

Task

You will receive a string of comma-separated integers and you will return a new string of comma-separated integers and sequence descriptors.

Input

"0,2,4,5,5,5,5,5,3,4,5"

Output

"0-4/2,5*5,3-5"

Performant index on date field

Is there a way to get a good performing index on a date field? I have tried various date property indexes and the query plan is always in a pretty high range. Below are query plan result values I have observed:

StartDate > '2019-12-01' --cost = 699168
StartDate = '2019-12-21' --cost 70666
StartDate between '2019-12-21' and '2019-21-28' --cost = 492058

The query plans above were for type %TimeStamp.

Returning values with python

Why am I writting this?

Last year I made an article for starters on using embedded python. Later, it started a little discussion on how to return values with python and I found some interesting observations that are worth writing a little article. Also, hopefully I can reach more people by writing this.

Possible situations

There are two things you'll need to care about when returning a value with python. The first is the type you're trying to return and the second is where you're returning it.

We're looking to create a quick and simple test to see if all firewalls are open on 1972 between a linux based web server VM and a VM running InterSystems IRIS. Does anyone have any ideas for a quick command that can be run from UNIX console that will provide confirmation that traffic is able to get to 1972 on an IRIS machine?

BTW - I don't think it makes any difference but the IRIS machine is running Windows

Hi,

Is there a way to insert new Key/Value in an existing lookup Table via a DTL code? The only thing I found in the documentation is that we could use the following command SELECT KeyName,DataValue FROM Ens_Util.LookupTable WHERE TableName = 'myTab'. In the meantime I just created a table and used it in my DTL to insert new values and validate if the Key exist.

Regards

Data import/export

I am creating "models" that contain rows in several class tables called Model, Path, Node.

So, model 19 includes 1 row in the Model table, 11 rows in the Path table, and 10 rows in the Node table.

I'd like to write some utilities to "move" model 19 from one instance to another.
