Hello Cache Developers: I was curious if anyone has ever created a TWAIN interface to their Cache Application? I am new to TWAIN and hence the reason for this question. From what I understand, TWAIN is software used by various digital imaging software and TWAIN provides an API for applications to call to be able to import images into their application. I work with a healthcare application and was wondering what types of things are required for a Cache Web Application to call the TWAIN API to be able to load images into a Cache table. Any input, sample code, or suggestions is apprec

Hi Community!

As you know we have Global Masters program — InterSystems Data Platform Advocacy Hub.

All Global Masters members (Advocates) can achieve various levels of advocacy which depends on contributions on Developer Community and activity in Global Masters.

Every new level opens new type of challenges/tasks and new types of rewards.

We are excited by how engaged you are with Global Masters but realised that we have a really great gap between initial level Insider and the next level Specialist. Indeed, Specialist level demands really great achievements: 10 articles, 10 questions on DC, article with 1,000 views.

So we introduced a new level of advocacy with name "Advocate".

See the details below.

Hello everybody,

We have a piece of Caché software which calls an external utility using $zf(-1,command). It works fine under Linux, but under Windows an external process occasionally hangs (due to some internal problems out of the scope here) and need to be killed programmatically. Having PID, it's easy to kill a process. If a Caché process is called with JOB command, the caller can easily get its PID from $zchild, but alas $zf(-1) does not seem to return the similar info. Is it possible to get it somehow?

Cluster deployment recipes?

Let assume you have a infinitely scaling algorithm implemented in your application, using replication, ECP, or any other means of horizontal scaling, and let assume you know how to run your system under any volume of requests, the trick is to deploy required number of computing nodes in the cluster. If we are talking about cluster of 2-4 nodes your administrator (or as they call it today "devops engineer") will install anything manually. Probably he will easily handle 5 nodes configuration in the cluster.

Hi,

I need to develop a HL7 Q22/K22 query/response mechanism for a NHS Trust I am working for, but I do not know how to handle the message continuation.

Can any one give me any advise on this and/or point me in the direction of any documentation on the subject?

Thanks

Hi!

I was trying to create a query that can be exposed as a stored procedure (function actually) that would return a resultset with a random number of columns.

Unfortunately, it seems that unless I specify the ROWSPEC annotation on the Query method, I won't get any columns exposed. I was hoping to implement QueryNameGetInfo method and specify the names and number of columns I would be returning dynamically. But it seems that GetInfo information is simply ignored.

Here is my code:

Hi all,

I have an operation which uses the SQL outbound adapter to query a data source set up using a system DSN on the server which uses the Intersystems ODBC35 driver (this is a cache db hosted elsewhere).

Whenever Ensemble runs the following query:

SELECT lnkdid,
c_fastsearch_code,
c_drugfull
FROM JAC.drug_basic
WHERE c_drugfull LIKE 'Para%'

No data is returned, however running the same query via SQL Server Management Studio, all expected rows are returned.

Also if I run the following via Ensemble:

Hello; We are managing several Ensemble instances on several servers. One server has 4 instances, and two other servers have one instance each (those are production servers). We encrypt all instances using the Caché encryption in the management portal.

Currently we are using two different encryption keys: 1 key on the server with 4 instances, which is used for all 4 instances, and a second key on single-instance server. ( I'm installing the newest production server now.)

Using Snapshots in BPL

I have a scenario where I am calling a business operation which populates and returns an EnsLib.SQL.Snapshot via dynamic SQL to a Business Process. I then want to iterate over this snapshot and call a RecordMap Operation to write those records to a delimited file.

Is this the correct way to do something like this? If so, does anyone have a sample which illustrates its correct usage?

When the snapshot is returned I save it into a context variable with:

set context.Snapshot=callresponse where the pOutput variable of the operation is set to EnsLib.SQL.Snapshot.

Develop integration service

The InterSystems IRIS has an integration engine with these core elements:

1. Adapters: are inbound (data/message input/request) and outbound (data/message output/response) integration logic specialized in the type of data or message protocol (file, http, etc.). They are the interface to allows connect with source or target data repositories or systems.

2. DTL: is a component to mapping and transform data between two components in the flow orchestration.

Hi Community,

I am trying to remove a duplicate OBX from a result, but I am running into some issues. Let me explain.

First I had a OBX where the observation Value had the blood type in it and the following OBX had the result in it.

The clients wants the blood type and the result in one field. therefore I merged / concatenated the observation values of the two OBX's.

I tried removing the OBX:2 but just cant take the whole segment out.

please see examples below

This is the result.

This is a translation of the following article. Thanks [@Evgeny Shvarov] for the help in translation.

This post is also available on Habrahabrru.

The post was inspired by this Habrahabr article: Interval-associative arrayru→en.

Since the original implementation relies on Python slices, the Caché public may find the following article useful: Everything you wanted to know about slicesru→en.

Note: Please note that the exact functional equivalent of Python slices has never been implemented in Caché, since this functionality has never been required.

And, of course, some theory: Interval treeru→en.

All right, let’s cut to the chase and take a look at some examples.

We have multiple server and multiple namespace.

I have a script having sql query which fetch data from current namespace of a server.

If I want to run the same query on different server to fetch data, but I want to run that script on just one server for all server.

Please let me know how can I proceed.

NewBie's Corner Session 17 New command

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

New command

The New command limits a variable's scope or range of use. In theory the New command is simple, in reality the New command is powerful and needs to be respected and understood. In Caché ObjectScript and MUMPS an entire chapter is devoted to it.

There are three variations of the New command:

Configuration

Cache 2016.2 running on fully patched minimal CentOS 7 install. No Firewall.

Atelier running on Centos 7 Desktop. No Firewall.

I was able to build and compile classes from Atelier.

When I try to run a routine or some class code from Atelier I get an error. It tells me to look at the Network Activities view.

When I do that I see the following:
