Some technical background information

There is not just one class in this package:  rcc.gstream.cls but also rcc.gstreamT.cls

While rcc.gstream works with direct access to the stream globals, the *T version uses
a Process Private Global (PPG) as Temporary storage.
using  SELECT * FROM RCC.gstreamT WHERE RCC.useT('^jpgS')=1 and similar.

This might be an advantage for multiple access to the same stream in sequence,
The advantage is obvious: You have a personal snapshot in memory and no risk of
a conflict in access. This might be interesting if you work just on 1 specific stream.

I have the following servers in IRIS mirror set:
Arbiter; isc_agent only
LIVETC01; IRIS DB full install; Primary
LIVETC02; IRIS DB full install; Backup

A couple of days ago IRIS hung.
The application using LIVETC01 DB stopped functioning.

I'm trying to find out the sequence of events leading up to the failure.

I see these entries in the log:
Arbiter:
2023-01-17T15:54:56 ISCAgent: Arbiter client error: Message read failed.
2023-01-17T15:54:56 ISCAgent: Completed serving application: ISC1ARBITER
2023-01-17T15:54:56 ISCAgent: Arbiter client error: Message read failed.

I have a production with one Business Host - a Business Service which I need to scale automatically to consume ~80% of CPU time.
Business Service pulls data from a (non-FIFO) queue so that I can adjust pool size without any issues.

So far, I'm planning a different BS running every X seconds and sampling CPU with $system.Process.GetCPUTime() and scaling the pool size of the main BS up/down based on that metric.

Has anyone tried something similar? Any advice/code samples would be appreciated.

Applications that work with bill payments and receipts, as well as the delivery and inventory of items, generally require the use of barcodes or QR Codes. The latter is used in even broader scenarios since the QR Code can store more information than a simple bar code. Thus, it is important to have the ability to generate barcodes and QR Codes or read the data stored in them from an image or a PDF. This article will show you how to do this using Python and some of its free libraries.

Hi All,

Hopefully  someone can help me with this case. I need to encrypt a text(querystring) with an AES265 encryption. An other vendor is decrypting this information. I have a working class in C#. I've tried to build the same in Objectscript for the encrypt part but there's a missing link somewhere.  What's the difference between the C# and Objectscript implementation?

Objectscript code (until now):

Class TEST.ENCRYPT
{

// Symmetric Keys sample to encryptClassMethod DoAESCBCEncrypt() As%Status
{
	set key="pZR8qfrz7t47G+dboyJCH4NnJRrF+dJbvxq37y/cLUo="set iv=##class(%PopulateUtils).

Hi All,

I'm looking to write a 3rd party front end for BI cubes and have been directed towards the REST API here: https://docs.intersystems.com/iris20222/csp/docbook/DocBook.UI.Page.cls…

I've had quick test using postman and can use those fine, the issue I have is that there are some areas of metadata not exposed by the api that are essential to write a front end tool. I can list the cubes and measures using the /INFO/ paths, but that seems to be the limit of what is available.

Hello all,

I just started learning SQL and am also new to Cache...

I am dealing with a simple SQL query and trying to understand the components of the following expression do:

STRING(city_name, ' - ', city_code) into :CODE, :VALUE 

I understand what the STRING function does. However, I am lost after that:

"into:CODE, :VALUE"

What do these do?

Thanks!

Hi!
I have an issue when trying to generate an object when reading an XML file. All files I'll mention will be attached to this post as a PDF file, but it's really a ZIP one.
The XML file is used as a template to generate a PDF report through the JasperSoft Report API. I checked the file consistency, and it's all right. We are able to generate the PDF file with no issues. What we need to with Caché, is to read the XML file, correlate it to an object, so we can change properties from this file.

Hi Community,

Watch this video to review the present of InterSystems cloud services and use cases, as well as a roadmap for the future:

⏯ InterSystems IRIS Cloud On-Demand Services @ Global Summit 2022

I have noticed that the way the nodes are ordered is different between 2 different environments.

If I create the following global :

set^TEMP("Z")=1set^TEMP("Ä")=1

Then I dump it with zwrite, I get this (which is expected):

^TEMP("Z")=1^TEMP("Ä")=1

However, on another machine, it gives me this :

^TEMP("Ä")=1^TEMP("Z")=1

The same goes for the following command (which return 0 or 1, depending environment) : 

write"Z"]]"Ä"

Both are running Windows 10, but one is running IRIS 2021.1, the other CACHE 2017.2.2.

I don't think that's the reason, maybe there's something else (a configuration in Portal).

This article will describe and include an example of how to embed an external PDF file into an HL7 segment, specifically ADT_A01:2.3.1 OBX().  This can be useful when attempting to insert pictures or other external data into an HL7 message.  In this example, the name of the PDF file to be embedded is provided in the incoming HL7 message in OBX(1):ObservationValue field.

The basic stipulations for this example are as follows:

1. Accept a PDF file
2. Accept an HL7 message
3. Using the name of the PDF file, embed the PDF data into the HL7 message
4. Output the message to file

Using EnsLib.

In the previous article, we've discussed the origin of the standard HL7v2, the structure and the types of messages. Let's now look at one of the most used types of messages and an example of its structure. I'm talking about ADT.

HL7 ADT messages (Admit, Discharge, Transfer) are used to communicate basic patient information, visit information and patient state at a healthcare facility. ADT messages are one of the most widely-used and high volume HL7 message types, as it provides information for many trigger events including patient admissions, registrations, cancellations, updates, discharges, patient data merges, etc. 

What would be the syntax for something like this

ws['A1']= "blah"

I did try

set ws("A1") = "blah"

however that didn't work

Hi community,

I am working on Converting Non HL7 message (Using record maps) into HL7 message.

1.Can anyone share few details how to save Non HL7 message into SQL table and the converted HL7 message into SQL table

2.In Message Viewer is there any SQL tables are linked to the session id or where the information regarding the message will be stored? Will the message trace details are stored in globals or in SQL table,If yes can anyone share the details in which tables or globals will it be stored?

HI ! I'm working on a caché upgrade to IRIS.

in some abstration cls classes, to get a property was used $METHOD(..Obj, propertyName_"Get").
On Caché 2018,  had as a return property value, if the property does not exists, an exception of type <PROPERTY DOES NOT EXIST> throwed

Now, on IRIS 2022.1,  will always be throwed an exception of type "<METHOD DOES NOT EXIST>".

I can change  $METHOD  to  $PROPERTY, but as it is an abstract class, I cannot guarantee the type of the referenced Object, if the property is encapsulated or private, I need call $METHOD(.

I'm trying to add the greater than or equal character on a ZEN PDF report and was wondering how and what code I can use Unicode to print it.

Is is as simple as using $c

My team works on implementing an Interoperability solution utilizing InterSystems Kubernetes Operator on Red Hat OpenShift container platform. 

We are trying to determine how many messages we can process in any given time. We have a Feeder app running in 10 containers sending 50k messages each to a load balancer all beginning at the same time.

Messages are received via HTTPS protocol by webgateway containers. 

Interoperability production runs in compute pods with persistent data, journals, and WIJ volumes.

We implemented Horizontal Pod Autoscaler to scale compute pods when CPU utilization is high.

We're having a problem with the way Python modules are being cached in Iris. If we modify some code and then reimport a module it is still processing the old code.

E.g. Create a python file:

I have a pvot table defined. that generates a set of data.   I want. to. execute the pivot table programatically  which I believe involves using %DeepSee.ResultSet.  Does someone have an example showing how to apply filters to the results?

For. example

Thanks

Hi Community,

I have created Tier 1 CCR and when I move it to Live it shows the below error.

Hi Interoperability experts!

I'm into interoperability now with data transformations and I wonder: how can I use DTLs?

I've created one that transform Ens.Request into Ens.Response. How can I use it now in the production?

I'm trying to add the business process expecting to see it available in the list but it seems it is not the case. 

Tried documentation and it doesn't say either what to do after creation the DTL.  If it is obvious could you please help?
