I have global with binary data, structured like:

^a(1)=<binary>

^a(2)=<binary>

^a(n)=<binary>

What could be easiest way to read it via Stream interface? I.e. to pass an adapter to a function expecting Stream?

Hi

I am trying to upload a file to a ftp site using following code. Problem is file is getting upload but there is no data. Can you plz advise where I am getting lost. Also my files are with big data, 2+ GB, as far as know this ftp upload will not effect on my cache.dat size. Plz correct if my understanding is not correct.

Set ftp = ##class(%Net.FtpSession).%New() set sc = ftp.Connect("myFtpServer","myUserID","myPswd") Set filestream = ##class(%Library.FileCharacterStream).%New() Set sc = filestream.LinkToFile("\Temp\GaganTest") set newname = "PrintWaitDetail-14936.xls" Set sc = ftp.Store(new

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

s @(..#Array)@(1)=1

3. Documentation comment

Just document it to have it in a class documentation

/// ^MyGlobal is used to store my data

Hi ,

I would like to know if there is possibility to disconnect child from parent in Parent/child relation and move child to Other Parent? 

Object Synchronization is a feature that has been around for a while, since Caché days, but I wanted to explore a bit more how it works. I've always thought that database automatic synchronization is complex by nature but, for some particular scenarios shouldn't be so hard. So I considered a very simple use case (OK, perhaps the typical one, I'm not discovering anything... but if it's common and it works, it's good ). You can download from GitHub and compile it into your system, generate sample data and play a bit with it. It's done for InterSystems IRIS but it also should work in last versio

Hi all,

One of the most useful features for me in IRIS was the queue page. From there, I could see how the different elements (BS, BP & BO) from a production were behaving, thanks to the possibility of auto-refresh every second. Great thing.

But we have updated to 2019.1 and this possibility is gone... we need to refresh manually! So, is there any way to set a parameter somewhere to have the queues status refreshed automatically?

Thanks a lot.

 I have two local instances:

• IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
• IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

• jar
• generated class
• java version

They are calling the same method with this java signature:

package isc.rabbitmq;
public class API {
    public void sendMessage(byte[] msg) throws Exception {}
}

On the InterSystems IRIS side I'm calling it like this:

set sc = ##class(%Net.Remote.Service).OpenGateway(gatewayName, .gatewayConfig)

Hi,

Is there any way to set environment variables in Linux from Cache?

I see a way to get an environment variable with: $system.Util.GetEnviron()

Essentially I am converting from VMS (DCL) to Linux.

In VMS we used $ZF(-1,"SETSYM") in Cache to a value and then interpreted that value in a DCL procedure.

Actually, I think I should just explained the need. We are writing linux scripts that call cache routines and we would like to pass back a value indicating failure or success to be handle it in the linux script. Right now we are writing out a log file, opening it and searching for a string. An

The newer dynamic SQL classes (%SQL.Statement and %StatementResult) perform better than %ResultSet, but I did not adopt them for some time because I had learned how to use %ResultSet. Finally, I made a cheat sheet, which I find useful when writing new code or rewriting old code. I thought other people might find it useful.

First, here is a somewhat more verbose adaptation of my cheat sheet:

I have a list property that I query from the database to get the values contained in that list using $LISTFROMSTRING() when the list is returned the list values contain a rectangle like character similar to when you copy past something to the Terminal and it has a preceding space .The problem is I need to compare those values to other values and they do not match because of this value I have tried to use $EXTRACT(value,*W) and *P but this is not striping the preceding character how do I get rid of this character any ideas please. 

the values returned from the Database

We have created a custom SDA container to store a certain kind of new, customized patient data.

We are observing a behavior in the correspoding analytics table for this custom SDA class where rows are added for a patient for which the MPI is null and the patient record does not exist.

From what we can tell, it seems that, when there is a MPI link/unlink, rows are added to analytics linked to the new Patient record that contains the latest MPI, but the old rows linked to the old (now non-existent) Patient are not removed. We are concerned why this is happening, since, in our testing, it does not

I have an OAuth 2.0 development environment where Caché is serving all three roles as the Authorization Server, Client and Resource Server based on a great 3-part series on OAuth 2.0 by @Daniel Kutac. I have a simple password grant type where an x-www-form-urlencoded body (as described in this post) is sent as a POST to the token endpoint at https://localhost:57773/oauth2/token and a response body with a HTTP Response 200 header is returned. The response body looks something like this.

Hi,

I am trying to use the  LogicialToDate method in the %Library.FilemanDate class.  In the class documentation it talks about the parameter STRICTDATA (see below).  I would like to set the STRICTDATA to a 1 but I am not sure how to do that when using this method because the method does not reference this as a parameter to be passed into it.  (see below).

How do I set the parameter?

Thanks

Hello All.

In need of some help.

We are currently migrating Interfaces from JCAPS to HealthConnect 19.1 and have done a lot of work on our Dev server.  I am looking to copy/export this work over to the Test server and have managed to export the production and Rules, HL7 custom Schemas etc.  The only thing left now are the Data Transformations but so far I can only find ways of copying the transformations over individually.  Is there some way to copy all of the transformations we have produced in our namespace to another server in one go?  

Thanks

I have created a custom container that contains medication adherence data. I want to know the best-practice way of querying the data for to display in a custom Zen page in the Clinical Viewer for a given loaded patient.

Let's say the custom class is called Hospital.Data.MedicationAdherenceData. Let's say the streamlet class is Hospital.SDA3.Streamlet.MedicationAdherenceData

I can look up the data by using the Sequence number as viewed in the HS.Viewer.Services component trace after loading up a patient in the Clinical Viewer. I do this by selecting from the custom streamlet class using "T+[seq

How can I round to the next whole number?

.1 = 1

1.2 = 2

1.7 = 2

Hi, I had written one .net service for excel validation , after validation the data will be inserted in DB. I am getting value from an outbound message but the values are not inserting in DB. i have two classes one is for reading the value from excel and convert that into ensemble objects, here i am getting value. Another class for inserting the values from the ensemble objects but here i given a global variable for checking . It's shows global variable does not exist. I don't why it's not entering to 2nd class. Please give me the step by step explanation

I would like to allow some departmental user to view the  ensemble portal.  I want to make sure they are not allowed to  do any changes (like stop and start interfaces from portal)

I have created  one userbut limited with SQL privilages.  But  using this account,  the portal view is not accessible.

It would be appreciated if anyone can adice me on this. I know this may be a silly question.
