Question Virat Sharma · Jan 23, 2023

Hi All,

I am a beginner in cache. I need to extract data from multiple tables (4-5) tables based on an SQL query . The data is more than 9 lakhs of records (i checked using count). The total number columns is 16. 

When I am running this SQL query through management portal, I am getting time out exception. Could you please suggest how I can retrieve those records. Which way will be good (Dynamic query using %SQL.Statement or Embedded SQL (not known to me) or Writing to a global will help or not). 

I tried using CSV but there are few columns that contain comma and because of which I cannot use CSV

Question Phillip Wu · Jan 21, 2023

Hi,

Is there a way of printing out information about IRIS.DAT file eg. database name?

The reason is that I've "refreshed" TEST system from LIVE system and I'm not sure I've the copied the correct file to the correct place

on the file tree. The file tree structure shows the database that IRIS.DAT represents. 

eg. /db/HMF/IRIS.DAT should be the HMF database

Question Stefan Cronje · Jan 22, 2023

Hi all,

I am trying to use some process private variables (percent variables) in Triggers.

I am referring to values from $System.Process, like the ClientIPAddress and CSPSessionID.
These do to not contain values and I suspect it is bacause of scope. I also checked, and the %session variable is not available if the change originated from a CSP request.
I know that in triggers the scope of the variables are to be kept local, that is why NEW is to be used.

Is there a way to access the Process Private Variables in Triggers or get $System.Process to return the correct values?

Thanks.

Question Phillip Wu · Jan 23, 2023

I want to refresh the TEST DB from LIVE.

On TESTTC02, I'm getting the error:
"Missing Mirrored Databases Report"

Questions.
1. What causes this problem?
2. How do I fix it?

Thanks for any help
=========================
This is the basic plan for the refresh:
DR copy IRIS.DAT files -> TESTTC01
TESTTC01 IRIS.DAT files -> TESTTC02

These are the details:
SMP=System Management Portal – the GUI web interface into IRIS admin
DRTC01=DR node of LIVE (async mirror)
TESTTC01=Primary member
TESTTC01=Backup member

This is what I did:

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.
The disadvantage is

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:

Question Eduard Lebedyuk · Jan 19, 2023

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.

Pyzbar library

The pyzbar library reads one-dimensional barcodes and QR codes from Python 2 and 3 using the zbar

Question Norman W. Freeman · Jan 19, 2023

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).

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(..Obj, propertyName_"Get").

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.

Hi Community,

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

I initially had changes deployed through a different CCR to the TEST environment and were not deployed to LIVE for the same class.

I tried to cancel it so that I can move these latest changes but I still get the below message.

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?

Why I decided to write this

Recently I had the challenge to create a secure authentication method to authorize access to some data, but unfortunately I had zero experience with those security configurations and I felt that I was missing some basic concepts to have a better understanding of the official documentation.

After studying and managing to deliver the classes that I was asked to develop, I'd like to share a little bit of my new knowledge, which helped me follow the topics in the documentation.

Starting with the basics: the holy trinity of servers
