I have 2 instances of Cache, one of 2010 and the other 2016.  On both I have created a SSL Configuration with same name.

When I connect to a SOAP Service Client from Cache 2010, I get the above error.

If I connect from Cache 2016, the connection get through.

How can get more details of the error in the Cache 2010 instance to be able to fix this issue.

I have enabled the SOAP Log and it does not give much of details.

Developing a Full-Stack JavaScript web app with Caché requires you to bring together the right building blocks. Previously, I outlined the basic steps to install and connect Node.js to Caché and make it's powerful multi-model database capabilites available for use with Node.js. You can use Caché as a NoSQL-, document- (with unique key-level access!), SQL- and object-database with Node.js. When developing JavaScript applications, you'll see how powerful this combination is and makes Caché a perfect fit for Node.js.

In the first part of this article series I will show how to get started with the React framework, one of the most popular frameworks currently taking over front-end development. In the next parts you'll learn how to connect a basic web app to a Caché back-end.

You'll see, it's very easy to get started with this technology - you can even compare the amount of basic knowledge you need to COS because you only need to know a few basic concepts to start!

In my previous article, we reviewed possible use-cases for macros, so let’s now proceed to a more comprehensive example of macros usability. In this article we will design and build a logging system.

Logging system

Logging system is a useful tool for monitoring the work of an application that saves a lot of time during debugging and monitoring. Our system would consist of two parts:

  • Storage class (for log records)
  • Set of macros that automatically add a new record to the log

zen report

Hi, all

I have the following problem in generating a PDF report in ZEN, which has many items, a general total of approximately 30,000 items, but gives an error, I can generate a report with a maximum of 8,000 items, which may be wrong.

So, one day you're working away at WidgetsDirect, the leading supplier of widget and widget accessories, when your boss asks you to develop the new customer facing portal to allow the client base to access the next generation of Widgets..... and he wants you to use Angular 1.x to read into the department's Caché server.   

There's only one problem:  You've never used Angular, and don't know how to make it talk to Caché.

This guide is going to walk through the process of setting up a full Angular stack which communicates with a Caché backend using JSON over REST.

Whenever the Windows SNMP Service restarts, the snmpdbg log says the following. 

13:08:59 :Attempting initial TCP connection(s) with 1 Cache instances ...
13:08:59 :Get connection with ENSEMBLE on port 1972
13:08:59 :Connection refused on port 1972, check if Cache instance ENSEMBLE is started.
13:08:59 :Cache iscsnmp.dll initialized for 1 configs

Ensemble and all productions are running. I've set up Caché SNMP agent on many other servers in our company and those are working fine. However this one server won't budge.

In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions. The majority of solutions I see today are deployed on Linux on VMware so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Can someone give me an example of how to JOB a class method that requires an array of values to be passed to it by reference.  

This is what I tried, but am getting compile errors because of the .params

job ##class(%SYSTEM.OBJ.FM2Class).All(.params)::5

Any thoughts on how to accomplish this, the simplest way.  I would like to avoid writing all of this to some global and having to write some wrapper to pick it up and then call the class method, which I certainly could do.  but is this the only way to do it?

Cache ODBC - Access Denied


I'm working on integrating a Cache database into an existing .NET project of mine.  I'm trying to execute certain queries utilizing the Cache ODBC driver.  The first error I ran into was "[S1000] [Cache ODBC][State : S1000][Native Code 417] Access Denied".  The part that's throwing me for a loop though is that the application ran ~200 successful queries before I started getting that.  After some of those Access Denied errors, they turned into "[Cache ODBC][State : S1T00][Native Code 450] Request timed out due to user timeout".  This was all with the regular (2.5?) driver.

Note (June 2019): A lot has changed, for the latest details go here

Note (Sept 2018): There have been big changes since this post first appeared, I suggest using the Docker Container version, the project and details for running as a container are still in the same place  published on GitHub so you can download, run - and modify if you need to.

I am experimenting with Relationships, both Parent to Child and One to Many.

I have done some SQL look-ups and have searched through the documentation, however not in a lot detail, but wonder if there are more and better ways to access both sides of Relationships through SQL?

Thank you in advance for any help provided.

Full-Stack JavaScript development allows you to create state-of-the-art applications with Caché. With any (web) app you build nowadays, one has to make a lot of architectural decisions and you want to make the right ones. With the Node.js connector available for Caché, you can create a very powerful server side application server, allowing you to use the latest JavaScript technology and frameworks client- and server-side.

With all these new technologies, the most important is to integrate them in the most efficient way and to create a very productive development experience. This article willl get you started step-by-step with Node.js technology.

Web Sockets


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?

The COS Faker

Hi Community,

This post is to introduce one of my first project in COS, I created when started to learn the language and until today I'm keeping improve it.

The CosFaker(here on Github) is a pure COS library for generating fake data.

cosFaker vs Populate Utils

So why use cosFaker if caché has the populate data utility?

Bug killing development tips

Does anyone NOT use a debugger? I can't remember the last time I did. It's not because I don't dislike them, I just don't need to use them. The main reason for this is because I have a certain development methodology that either produces less bugs, catches them at a unit test level, or makes tracking them down much easier.

Here are my tips...

1. Write your own COS cheat-sheet.

In the first article I started discussing RESTForms - REST API for your persistent classes. We talked about basic features, now, I'd like to discuss advanced features - mainly queries capabilites:

  • Basic queries
  • Query arguments
  • Custom queries


Queries allow getting slices of data, based on arbitrary criteria. There are two query types in RESTForms:

  • Basic queries work for all RESTForms classes once defined and they differ only by the field list
  • Custom queries work only for the classes in which they are specified and available, but the developer has full access to query text

Hi ,

I am stuck with unit  test failure with intersystem . In case of unit test failure, the build in jenkins is succeding while the build in jenkins should fail in case unit test failure .

In cache programming i am using %UnitTest.Manager class and DebugRunTestCase method within it. I'm able to link studio with jenkins. I wanna fail my build in jenkins, if any of the test cases fails. Could anyone help?

Database systems have very specific backup requirements that in enterprise deployments require forethought and planning. For database systems, the operational goal of a backup solution is to create a copy of the data in a state that is equivalent to when application is shut down gracefully.  Application consistent backups meet these requirements and Caché provides a set of APIs that facilitate the integration with external solutions to achieve this level of backup consistency.
