Running a Background Job using the JOB command is a well-known feature.
Using ECP to distribute databases to several servers is also well-known.
But using the combination of both to run a process on a different server
seems to be a rare case.

Sure there are enough other ways to start a remote job, but the special
combination with ECP where the application server starts a process on a
data server without additional networking is worth to be remembered.

How do I send request on production start?

Here's what I got so far in my production class:

ClassMethod OnStart(pTimeStarted As %String) As %Status
{
    job ..InitialTraining()
    quit 1
}

lassMethod InitialTraining() As %Status
{
    hang 5
    set sc = ##class(EnsLib.Testing.Service).SendTestRequest(...)
    quit sc
}

Is there a better way without hang, etc?

Hi all, 

I am trying to create multiple tasks all in a single task. 

For instance MyApp has three tasks.

One to send a email if a limit is exceeded = MyApp-check-credits

One to purge files = MyApp-purge

One to auto delete files = MyApp-Del 

I would love to get all tasks MyApp-check-credits, MyApp-purge, MyApp-Del into a single parent task called MyApp-AllTasks.

Is there anyone that could give me guidance of how to complete this it would be much appreciated.

We are currently trying to implement TortoiseGIT into Cache Studio as per the following Github project

https://github.com/intersystems-ru/cache-tort-git

Our architecture is as follows:

- A server with Ensemble installed on

- Team of several members connect to the server and perform their code build

TortoiseGIT was installed on the server, however, should the REPO location be:

- on the server itself (as a shared path)? 

- locally on every developer station? If yes, how would this be set up?

This example is extracted from a long-running installation.
The purpose is to have simple monitoring of several servers at a rather primitive level.
Just slightly more intelligent than a raw PING. But still easy to integrate.
It avoids the overkill of information you are often confronted with while you are just
interested in the number of active processes or similar basic figures.
The example shows a basic skeleton that might be easily filled by your real needs.

It consists of 3 sections:

Hi Guys, 

I have a DB server (ser-app-db) where IRIS is installed as server.

I have a Web server (ser-app-w) where IRIS is installed as web server and configured as CSP gateway.

I followed the configuration guide and ser-app-w perfectly display the CSP and CLS pages.

But that's not working for my REST service, for exemple with the REST sample:

http://ser-app-db/REST/CRM/Get?ReqID=123(GET): work and show the request

http://ser-app-w/REST/CRM/Get?ReqID=123(GET): return a 404.

I am using Apache server in Linux box.

I am not sure what I am missing in the config.

httpd.conf file (pasted required part):

Hello,

I want to search a process ID in Object Script using the reference variable e.g. 1119102928 and kill that process ID. Please guide how it can be achieved.

Thanks in advance.

Hi community,

I need to create a DTL to get values from a JSon (%DynamicObject) to a class.

Thre first items is copied fine, however when it tries to get the values from an array it raises an error.

I' have done some tests with Caché and Apache Zeppelin. I want to share my experince to use both systems together. I'll try to describe all steps that are required to config Zeppelin to connect to Caché.
 

What is  Apache Zeppelin?

For all who think: What the heck is Apache Zeppelin?, here some details what the project site (http://zeppelin.apache.org) says:

PHP, from the beginning of its time, is renowned (and criticized) for supporting integration with a lot of libraries, as well as with almost all the DB existing on the market. However, for some mysterious reasons, it did not support hierarchical databases on the globals.

Globals are structures for storing hierarchical information. They are somewhat similar to key-value database with the only difference being that the key can be multi-level:

Has anyone worked with OPC Unified Architecture protocol (iot/machine to machine communication protocol for industrial automation)?
If so, how did you communicate with it?

Hi all,

I am trying to delete an item from a production through a routine that installs and disables items.

To add any item, I have no problems, even to enable and disable some particular items.

The problem arises when I try to eliminate the production item, because when it does, the production become unstable and only works again when this item is added again in the collection (or the item is deleted manually in the production.cls)

This is my code attempt:

Hello,

My company is looking evaluate upgrading to HS 2019 and I am not sure where to obtain a copy of this installer. Any help on this and a evaluation liscense would be appreciated.

In the previous parts (1, 2) we talked about globals as trees. In this article, we will look at them as sparse arrays.

A sparse array - is a type of array where most values assume an identical value.

In practice, you will often see sparse arrays so huge that there is no point in occupying memory with identical elements. Therefore, it makes sense to organize sparse arrays in such a way that memory is not wasted on storing duplicate values.

In some programming languages, sparse arrays are part of the language - for example, in J, MATLAB. In other languages, there are special libraries that let you use them. For C++, those would be Eigen and the like.

Globals are good candidates for implementing sparse arrays for the following reasons:

Hello,

currently we have a problem in development with the character set of the response message.

We are transmitting an HL7 message with an operation based on the EnsLib.HL7.Operation.HTTPOperation class.
We have changed this as follows.

Set pMsgIn=$$$NULLOREF, tHttpRequest=##class(%Net.HttpRequest).%New(), tHttpRequest.WriteRawMode=1, tHttpRequest.ContentType="APPLICATION/HL7-V2; charset=UTF-8"

Unfortunately, the ContentType character set is not read correctly in the response.

This is the response:

Hi everybody

I'm new in this forum and also new working with a Caché-Database.

Problem:
I have to delete records from a table (by SQL) which contains a field declared as:
Property Image As %Stream.FileBinary;

When I try to delete a record with an image I get an error
[%msg: <FEHLER #5019: Kann Datei 'H:\BK Solution\DSTBern\eXpert\Data\Expert\stream\YJC7o7ngR9WUeA.stream' nicht löschen>]
[SQLCODE: <-412>:<Allgemeiner Stream-Fehler >] 

because the physical file doesn't exist (for any reason) but the database want's to delete this file.

Hi, 

The app of the week is the 'ObjectScript Visual Editor'. 

It looks interesting but the GitHub ownload link[1] given on the InterSystems ObjectScript Visual Editor Open Exchange page[2] fails.

InterSystems IRIS from Spark to Finish

Hi Everyone,

Hi everyone,

Im new  in cache, i came from Java and im missing some features that i couldn't find in the documentation,  I hope you can help me with this questions.

Just a brief introducction: 

- Im in a project with old cache version, so saddly i can't use Eclipse + Atelier, so im using Studio.

- Currently im in a project with persistent classes, we want to turn apart the globals and focus on tables. 

The questions:

Hi,

recentley we started to work with Atelier & VSTS in our organization .

we are looking for a way to use the VSTS as Our Version/Source control system .

I have read the article about "Continuous Delivery of your InterSystems solution using GitLab" & now trying to find a way to use a similar metodology with the VSTS that we have in our organization.

It Apeares that it is possible to Create a Git Repository in the VSTS but i'm not sure how are we to use it from the atelier.

The main questions are:

In our table, we have a column cities,  which has a filter which displays the cities of a state depending on the state

For simplicity let's assume we have a page

Property State As %String =  "CA"

Our filter should run this query to show all cities of state ca

"SELECT Name FROM City WHERE State= "_%page.State

<tablePane>

<column colName="City"
filterQuery="SELECT Name FROM City WHERE State= <This is where I am stuck>"
filterType="query"
header="City" 
width="10%">
</column>

I am not able to pass any parameter to filterQuery. 

I have a class defined like this:

Class test.ABC Extends %RegisteredObject   {

Property myProp As %Binary [ Internal, Private ];

}

Is there a way to get a value of myProp from outside of the object?

I can't modify or extend the class obviously.

Hi, 

Most of my development experience is with HL7v2 interfaces and I don't have a background in web development and I'm very weak with javascript.

I'm looking for suggestions of learning resources to learn FHIR  and 'SMART on FHIR' (JavaScript, OpenID connect, OAuth2) for developers like myself who mostly do HL7v2 integrations - but see FHIR as the future - and want to develop their skills!

I've found these

Hi All,

I have two tables LB_TestSet and LB_Transfer

LB_Transfer has a list if TestSet row IDs, so i am doing the following join

SELECT 
LBTS_RowID,
,LBTS_CollectedDate
FROM SQLUser.LB_TestSet 
JOIN SQLUser.LB_Transfer ON ($LISTBUILD(LBTS_RowID) %INLIST LBTR_TestSetList)
WHERE LBTS_CollectedDate BETWEEN '2019-01-01' AND  '2019-05-10'

Without the date filter the query returns data, but if i add the date filter no data is returned

I also tried using %INTERNAL, %EXTERNAL TO_DATE('2009-01-01','YYYY-MM-DD')

Hi Community!

How do you create SSL Configuration for InterSystems IRIS programmatically? E.g. for installation or deployment case?

E.g. if I need to create a very simple "default" SSL client configuration to let HTPPS Get requests to an arbitrary server?
