Hi

I am working on a project that will interact with some software called ROS (Robot Operating System). One of the development challenges we have is as follows:

ROS uses web sockets... So one connect with ws://localhost:9090 to the web socket server.  It starts off as http, but then "upgrades" to web socket.  It then keeps open this "tunnel" for bi-directional communication..

I need something like a HTTP Outbound adapter, but the Web Socket version of it...

Does anyone have any experience in this area?

Hi guys,

Couple days ago, a customer approached me with the wish to enhance their existing legacy application, that uses SOAP (Web)Services so it shares the same authorization with their new application API based on REST. As their new application uses OAuth2, the challenge was clear; how to pass access token with SOAP request to the server.

After spending some time on Google, it turned out, that one of possible ways of doing so was adding an extra header element to the SOAP envelope and then making sure the WebService implementation does what is needed to validate the access token.

The attached code package provides a simple implementation of a web service client that utilizes the USPS Shipping API to normalize  an address.

This code requires the developer to obtain a USPS Shipping API user ID which can be obtained from the USPS shipping API website.  The assigned User Id can either be passed into the web service call as a parameter or can be coded as a parameter into the Request object.

Hi, 

I'm having a problem when I'm attempting to freeze the instance.

I have a pre-script and post-script to freeze and unfreeze the instance, but when the script execute: 

 csession INSTANCE_NAME -U '%SYS' "##Class(Backup.General).ExternalFreeze(\"$SNAPLOG\",,,,,,1800)"

 It's give me this error and fails the freeze: 

Backup.General.ExternalFreeze: Failed, Unable to switch local journal file, Error: -99,ERROR #1142: Error switching journal file: 0
vi

At cconsole.log file show this:

InterSystems has corrected a defect that can result in data integrity issues on systems using mirroring.

This defect affects:

• All currently released versions of InterSystems IRIS and IRIS for Health, except 2020.1
• Caché and Ensemble versions beginning with 2011.1.1
• All HealthShare products based on the above Data Platforms versions

This defect is more likely to be encountered in IRIS and IRIS for Health 2019.4. It is highly unlikely to have occurred on deployed systems running any other version.

The issue can only occur in a situation that meets all of the following conditions:

1. InterSystems has corrected a defect that can result in data integrity issues on systems using mirroring.This defect is more likely to be encountered in IRIS and IRIS for Health 2019.4.

The intersystems documentation gives the same description for both <MAXSTRING> and <NETWORK DATA UPDATE FAILED - MAXSTRING>. I suspect that the description for <MAXSTRING> is correct and the description for <NETWORK DATA UPDATE FAILED - MAXSTRING> was an accident. I would like to know what situation triggers the <NETWORK DATA UPDATE FAILED - MAXSTRING> error.

I want to create a CSP page that returns a pdf. The pdf is identified by a pdftoken parameter.

My goal is to validate the token and return the pdf (ContentType=”application/pdf”) if the token is good and return a text error message "Bad Token" (ContentType=”text/plain”) if the token is missing or bad.

My issue seems to be associated with ContentType. I can define one ContentType that works for the pdf or the error message. I am unable to change the ContentType.

Any assistance is appreciated.

Hello everyone!

I have an abstract class representing the possible inputs for an Enum field, in the following way:

I need to create a persistent class referencing the abstract class in the status field, so that the result of the operation is the same as the example:

Hi-

I have a class that specifies that streams should be stored in SSA.DocumentCacheS, however, they are getting stored in CacheStream instead.

How can I get streams to properly store in SSA.DocumentCacheS?

Here's the section from my storage definition that shows the StreamLocation

<DataLocation>^SSA.DocumentCacheD</DataLocation>
<DefaultData>DocumentCacheDefaultData</DefaultData>
<IdLocation>^SSA.DocumentCacheD</IdLocation>
<IndexLocation>^SSA.DocumentCacheI</IndexLocation>
<StreamLocation>^SSA.DocumentCacheS</StreamLocation>
<Type>%Storage.Persistent</Type>

Hi Caché-Developers!

My Caché Version: 2014.1 and the CSP-Gateway Version ( + Apache) also. I can't upgrade now. 

I want create a Web-Socket for my Chat  like in that Tutorial:

https://community.intersystems.com/post/tutorial-websockets

And there's my problem. When I set SharedConnection like:

set ..SharedConnection = 1

I get on init connection with the server that message:

First i think everything is okay but here i also didn't get the Messages on init from Server-Side:

When I now send a message to the WebSocket, I got following error:

Without SharedConnection = 1, everything works fine for me.

I know that collection is instance of %AbstractList.

But what about $listbuild? Does it possible to detect that given variable is instance of $lb?

Hi developers!

When @Evgeny Shvarov announced the first InterSystems IRIS Programming Contest, I started looking for new ideas.  

I put together a few ideas, and that's what isc-utils is about.

Create Database, Namespace, REST Applications using Portal Management is an easy task. You just need a few clicks or maybe more clicks than you expect.

But, what if you traded all those clicks for a simple command-line ?!

This code snippet changes all passwords in a system to a specified string. The two literal strings at the beginning of the snippet can be adjusted to edit the system or password string. The class method "test" runs the code:

Class eduardlebedyuk.changePasswords Extends %RegisteredObject
{
	ClassMethod test()
	{
        set ns = $namespace
	    zn "%SYS"
	    set NewPass = "NewPassString"
	    set rs=##Class(%ResultSet).%New("Security.Users:List")
	    set st = rs.Execute()
	    while rs.Next() { set st=$SYSTEM.Security.ChangePassword(rs.Get("Name"),NewPass)}
        zn ns
	}
}

DISCLAIMER: I am not an InterSystems engineer or a professional ObjectScript developer.

I just want to share my opinion about some things I am really miss in ObjectScript.

I really appreciate everyone who support my project (Declarative ObjectScript) in contest

but the post is not about "why you should support me" on contest.

I faced with ObjectScript in the university while was working on my diploma (in 2013).

Very good mentor @Evgeny Shvarov helped me to get started with ObjectScript development.

Hello,

We're considering adopting the ZPM solution as a way to manage many of our customer updates. However in order to do so we need to know a few things.

• Is ZPM client compatible with Caché 2017.x versions?
• Can we configure a self-hosted registry that doesn't require a GitHub repository link?
• Could the ZPM client zip and upload the whole package (all classes, routines, includes) instead of downloading it from a Github link?
• Can we declare a module that specifies classes themselves instead of their package counterpart? e.g. My.Class.CLS instead of My.PKG.

Hello,

Hello,While working on my Iris contest application FileMailer, I got an error today trying to send email with code that used to work. I added debugging entries and I can see it happens in %Net.SMTP class "Send" method. I am not using any credentials or SSL. I see it opens |TCP|25 device. It issues a series of commands to SMTP server (I was testing with smtp.va.gov and port 25). "init" command gets 220 response.  It runs "Login" method. Response is 250. The next command is "MAIL FROM" and I see 250 in the response with sender ok. The next command is "RCPT TO".

Introduction

The common requirement in many applications is logging of data changes in a database - which data has changed, who changed them and when (audit logging). There are many articles about this question and there are different approaches on how to do that in Caché.

IntroductionThe common requirement in many applications is logging of data changes in a database - which data has changed, who changed them and when (audit logging). There are many articles about this question and there are different approaches on how to do that in Caché.I'm sharing a mechanism that can help you implement your framework to track and record data changes. This mechanism creates a trigger through an "objectgenarator" method once your persistent class inherits from the "Audit Abstract Class" (Sample.AuditBase).

I hope you already know one of my projects Cache Blocks Explorer. I've recently renamed it to Blocks Explorer.

For the recent contest, I've added a new feature, the ability to generate a static picture of any Cache or IRIS database. Like below. Where unique globals have a unique color. This is how looks like inside 9.5GB database. Where 1 pixel represents one block. By link on image you will get even bigger image, with more detalization.

We are developing a Transformation and we are wondering: how could we debug and show a XML message which is being an output from a transformation, without storing it into request/response/callrequest/callresponse? We mean, how could we show a context variable in the production?

For example, let's have a transformation which stores an appointment in a variable called: context.especializadasConFormatoPrimarias

How could we show in the Production?

Currently it is being stored as the Transformation's output:

I just tried to log into our QA server and connect to Terminal (v 2013.1). 

I can type in my username but when I attempt to type my password, no characters are typed. When I press ENTER the password is invalid. 

I can connect to the management portal and the studio development environment without any problems.  Also, I do not have this problem when connecting to the terminal in our production environment (2010). 

Does anyone know what can cause this type of problem? 

Thanks. 

Hello,

We have a tranformation where we would like to convert a date from the following format:

"'dd/mm/yyyy' 'hh:mm'" (double quotes are just visual to indicate this is a string)

to date and time separated:

time: hh:mm

We have already splitted the datetime into date and hour as follows:

How do you decide the size to give to journal1 and journal2?
