InterSystems is delighted to announce the support of Docker container technology as a platform from the moment 2016.1 will be released.

Docker is a disruptive system technology that has many benefits and offers many advantages for those investing in infrastructure-as-code or immutable-infrastructure provisioning & deployment scenarios.
Like any new technology that appears, there is a learning curve, and many considerations need to occur when using it. However, Docker container technology has already proven to be successful by a huge follow-up with many companies already using it in production.

We have been storing raw messages in a MySQL database for DR and ad hoc purposes. We are thinking of using an Ensemble instance as our data lake instead. We could segregate the source data by namespace or by global. But either way we'll want a custom global to index the data for data retrieval performance purposes.

Anyone else taking this approach? Any feedback?

I want to upload several files using the html tag

< input multiple="multiple" name="BulkFileUpload" type="file">

. The upload.csp page in the SAMPLE namespace only shows how to extract a single file from the MimeData on the %request object. I cannot fathom how to extract multiple files from the MimeData in the %request object in cache. Can some kind soul explain to me how to do that?

Hope someone can help me,  so i was developing a script and during the tests I was using the csession to execute a method. Also i thought i had to stop the instance i was using, so I used the ccontrol stop [instanceName] to stop the instance, but when i restarted the instance i got this error trying to start my production, I have an idea of what's the problem but i don't know how to fix it.

ERRO <Ens>ErrException: <FILEFULL>zStartProduction+62^Ens.Director.1 ^Ens.Runtime("Name"),/hs-connect-hom/db/BPINTEGRADEV-GLB/ -- - registrado no log como '-' número - @' Set ^Ens.

Good morning

I'm probably overlooking something very basic, but I'm running on Win2016 with Cache  2016.2 - All the work I am doing is in INT routines, but I'm making some calls to the Host File system using $ZF(-1).

I have a few mapped Network drives that are mapped in Windows, typically these are locations where I want to back up some files.

My process is quite simple:

1. Read data

2. Zip data files using RAR

3. Create folder on Network drive

4. Move RAR files to new network share.

First time post, also a new Cache developer, hence the <Beginner> tag.

If our data has Predefined terms in a dictionary, and a user can add terms on their own, can the terms exist in different tables?

Lets call the tables "Terms" and the user data in "UserTerms".

If a third class definition has a property of "Term" can it not be either Terms or UserTerms?

I'm leaning towards using a Subclass strategy where the pseudo "Parent" (forgive me) is  Dictionary.Term and the child is along the lines of Dictionary.Term.User

Dictionary.Term.User can inherit from Dictionary.

InterSystems Caché globals provide very convenient features for developers. But why are globals so fast and efficient?

Theory

Basically, the Caché database is a catalog having the same name as the database and containing the CACHE.DAT file. On Unix systems, the database can also be an ordinary disk partition.

All data in Caché is stored in blocks which, in turn, are organized as a balanced B* tree. Taking into account that all globals are basically stored in a tree, global's subscripts will be represented as branches, while values of global's subscripts will be stored as leaves.

Hi, 

We recently moved our cache instance from windows 2012 to windows 2016 and when i try to now import % routines  i'm getting the following error  "Unable to obtain a write lock on this routine because either another user has the routine open for editing or you do not have write access to the database the routine is stored in. This item will be skipped."

This is a fresh installation of cache and I've moved the cache.dat and csp pages across. It seems to work fine but can't import % routines which I need. 

Has anyone experienced this and can help? 

Thanks

Hi dev community,

I am currently working on a project to send documents to a RESTful based API that supports bearer 
Token Authorization.

When we try to fire a JSON request from our EnsLib.Rest.Operation towards the 3rd party API with a 
valid Token we keep receiving Authorization Error codes HTTP 401 back.

If we use the same request and same Token from a test utility such as Postman the request is 
successful and we are able to move past the authorization stage.

We are inputting the Token in the header of the HTTP request as specified by the 3rd party API 
specification.

Hello,

We have defined four BPL Business Processes. One gets occasionally errors when pool size is two. No errors happen with pool size one. The error happens on calling %Save() on a large objects with many references to other objects.

Error #5803: Failed to acquire exclusive lock on instance of 'classname'.

Error #5002: Cache error: <ROLLFAIL> %TRollBack+10^%occTransaction

The error happens on a particular large object.

Our FileService gets the same Errors #5803 and #5002 with class 'EnsLib.EDI.X12.Document'

Another BPL gets the same errors #5803 and #5002 with lock on instance of 'EDIGW.BPL.ST837.

Other Sync-Tools just work from Caché/IRIS to Caché/IRIS.
Synchronizing your data to some external DB requires some other solution.

The solution is available in Caché/IRIS since quite some time and works excellent.
^OBJ.DSTIME does the magic.
https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2IMP_ch_current#D2IMP_C23869

It was built to allow data synchronization with DeepSee.
It keeps a very simple journal on Object/Table changes by signaling Modified,New,Deleted
This could be useful not only for DeepSee but for any other type of Table Synchronization.

The Global ^OBJ.

Let's say we have a class 

AbcRequest extends Ens.Request, PropertiesBaseAbstractClass(has all my properties common to all request)

Prop1

Prop2 and so on

Now in my Business Operation 

I want to make a json dynamically from this request.

Yes obviously I can do is

Set requestDefinition = ##class(%Library.CompiledClass).%OpenId("MyCreateRequest")
Set JsonObject    = ##class(%DynamicObject).%New()        

        for i=1:1:requestDefinition.Properties.Count() {  
            Set key            = requestDefinition.Properties.GetAt(i).Name
            Set value        = $property(pRequest,requestDefinition.

Hi Community!

We're pleased to invite you to the DMEA 2019 in Berlin – Europe's largest event for the Health IT industry.

Date: April 9 - 11, 2019

InterSystems' Location: Hall 3.2, Stand D-105

Please find all the details here: intersystems.com/de/dmea2019/

I have an application using examples from the lottery example in samples name space how do I create a dynamically link based on the data displayed to add a record id to the link

the idea is to loop over the records displays fields and link to edit the shown data at the end of the record in a table format

Fast Provisioning in Any Cloud

The 2019.1 version of InterSystems IRIS Data Platform is now Generally Available!

Kits and container images are available via the WRC download site

The build number for these releases is 2019.1.0.510.0.

InterSystems IRIS Data Platform 2019.1 provides the following new capabilities:

• Performance and scalability. The release features new performance improvements for parallel queries and data ingestion resulting in more than 50 percent performance improvement, and expanded sharding support with simpler rebalancing across nodes.
• Expanded cloud support.

We would like to know if there are any ramifications swapping out our code database while an Ensemble production is running. We are trying to minimize down time as much as possible and even though stopping and starting the production ideally would be pretty quick, is it possible that we could just restart the business hosts that had the code change?

So this is our setup: Ensemble 2016.1

global cache.dat code1 cache.dat code2 cache.dat

Namespace that we switch to point to either code1 or code2 and is mapped to the globals.

Has anyone done this?

Hi

We have just completed a migration of a test environment from Ensemble 2012 to Ensemble 2017 on a new server. This is the last in a series of migrations but the first to encounter this particular issue. All web clients making SOAP requests to a particular external web service are receiving a fault that states:

The SOAP action specified on the message, '', does not match the HTTP SOAP Action, 'http://<expected target service action follows here>'.

I've seen a few password change posts, but I wasn't 100% sure it was the same process, so I am asking here. We periodically have to change the passwords for a few Cache user accounts across several servers. Is there a process/script to change these passwords without having to go into the web portal on each server?  Thanks so much, and I apologize if this was covered in some of the other articles that I've run across. Just looking for the best method.

We can load a CCDA xml document into SDA3 object.

Once parsing SDA3 object, how do we determine from which XPATH from CCDA the specific SDA3 elements were mapped to.

Is there any way?

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

Hello,

Is there a way to implement Excel SLOPE and INTERCEPT statistical functions in Cache? Any help would be greatly appreciated.

Alex.

I am trying to convert a string to date but can not get it to work I have  function that I would like to take in a date string and covert it to date object

here is the ezample so far can not get it to work any help appreciated 

set p="12/03/2019"
 
w $System.SQL.TODATE(p,"YYYY-MM-DD")
 
<ILLEGAL VALUE>todate+32^%qarfunc

if I try this still get the wrong value returned

set p="12/03/2019" 
w $ZDATE(p,3)
1841-01-12

Version 2016

Created a business process and ticked "Is component".

Later trying to use it as component  from another business process, and when trying to set up target for a call activity, selecting process components does not show anything in the list.

Any idea why?

The 2019.1 version of InterSystems IRIS for Health is now Generally Available!

Kits and container images are available via the WRC download site

The build number for these releases is 2019.1.0.510.0.

IRIS for Health 2019.1 provides the following new capabilities:

• Interoperability. The latest release further expands the product’s schema, transformation, routing, and testing capabilities, supporting integration and service aggregation as a key enabler of digital transformation initiatives.

This is a continuation of my story about the development of my project isc-tar started in the first part.

Just having tests is not enough, it does not mean that you will run tests after all changes. Running tests should be automated, and when you cover all your functionality with tests, everything should work well after any change in any place.  And Continuous Integration (CI) helps to keep the code and deployment procedure with as fewer bugs as possible and automates the routine procedures, like publishing releases.

I use GitHub to store the source code. And some time ago GitHub started to work on its own CI/CD platform and named it GitHub Actions. It is not widely available, yet. You have to be signed as a beta tester for this feature, as I did. GitHub Actions uses quite a different way how to deal with a build workflow. What is important that Github Actions allows to use Docker, and it’s quite easy to customize available actions. And interesting that GitHub Actions is really much bigger than any classic CI like we have in Travis, Circle or Gitlab CI and so on. You can find more in the official documentation.

Hello all,

I am having some issues creating a docker image with a fresh cache installation. The error that I am getting right now is that gzip is required for a cache installation, but was not found in my system. Even though, this is shown as installed in the base centos 7 image. My host machine is Windows 10 using the latest docker version.

Here is my dockerfile, its simple:

FROM centos:latest

RUN yum update -y && yum -y upgrade

COPY ./cache-2017.1.3.317.0.18571-lnxrhx64.tar.gz .

RUN tar -zxf cache-2017.1.3.317.0.18571-lnxrhx64.tar.

Starting with 2017.1, InterSystems is adding Ubuntu (64-bit) as a third linux server platform. Prior to 2017.1 Ubuntu was already available as a development platform and customers could use InterSystems distributions build for SUSE to run on Ubuntu. As a result there are a few license key implications for 64-bit linux versions starting with Caché and Ensemble 2017.

Good day.

Can you please tell me how to programmatically get a list of DFI files that have been uploaded to the IRIS server?

Since CacheStudio can do this, it means that you can perform this operation from the code.

For earlier, I thank all who are not indifferent to my problem.
