#InterSystems IRIS

“I have been waiting for thirty seconds for service. This is outrageous!

If you're running IRIS in a mirrored configuration for HA in Azure, the question of providing a Mirror VIP (Virtual IP) becomes relevant. Virtual IP offers a way for downstream systems to interact with IRIS using one IP address. Even when a failover happens, downstream systems can reconnect to the same IP address and continue working.

The main issue, when deploying to Azure, is that an IRIS VIP has a requirement of IRIS being essentially a network admin, per the docs.

To get HA, IRIS mirror members must be deployed to different availability zones in one subnet (which is possible in Azure as subnets can span several zones). One of the solutions might be load balancers, but they, of course, cost extra, and you need to administrate them.

In this article, I would like to provide a way to configure a Mirror VIP without the using Load Balancers suggested in most other Azure reference architectures.

Hi,

I'm receiving in one of our interface a XML file as a %Stream.GlobalBinary, and in the source Application that produces this XML file, the user sometimes add a special character that force the XML file to have the header encoding to UTF-8, instead of ISO-8859-1 :

<?xml version="1.0" encoding="UTF8"?>

Hi Community,

I'm pleased to announce DEVBOX, the code anywhere IDE for IRIS.

Please watch the video and let me know what you think. Would you use it?

All the best,
Sean.

I did some experiments on my local machine and found out that IRIS seems to associate each request (eg: CSP request) to a dedicated process named IrisDB.exe

This process has 3 threads, and one of them seems to be the main working thread (that will the handle request).

If I spawn many concurrent requests, the number of IrisDB processes on my local machine will grow (to make sure each request can be handled in parallel).

It seems there is a limit : it will create no more than 64 processes to handle requests (eg: even if 100 concurrent requests are send to IRIS).

Hi,

I am trying to find out individual segment values in Message viewer and it display the values in Management portal, copied the query and run it on SQL editor, Segment values displayed with blank. Is there a way to get the individual segment values using query?

I am having a datatype DATE value from db 41966. And I want to convert it to epoch time.
Also, in case of DATETIME value how can I convert it to epoch.

It's a feature of ObjectScript (perhaps widely known, perhaps not) that if you open the same object ID multiple times, you end up with the same OREF. For example:

USER>set obj1 = ##class(Sample.Person).%OpenId(1)
 
USER>set obj2 = ##class(Sample.Person).%OpenId(1)

USER>w obj1,!,obj2
1@Sample.Person
1@Sample.Person

Generally speaking, this is an important feature - you won't end up accidentally modifying the same record via multiple paths and losing some of the changes.

In recent versions of IRIS, a powerful new data loading command has been introduced to SQL: LOAD DATA. This feature has been highly optimized to import data into IRIS extremely fast, allowing hundreds of gigabytes of data to be inserted in seconds instead of hours or days.

This is a very exciting improvement. However, a big problem in the data loading experience still exists. Namely, the time and hassle it takes to:

The meaning of each timeout value is as follows.

1. [Server response timeout]

If IRIS/Caché processing (routine or query execution) does not finish within this set time, the browser will return an error.

For example, if this value is 60 seconds and it takes 90 seconds to execute a routine/method/query, an error will occur.

2. [Queued request timeout]

Hi folks!

Just curious, how can I use $znspace in embedded python code?

How does other $functions work, e.g. $zv, $job, etc

Hi everyone,

Lately, I've been spending a lot of time with Visual Studio Code (VSC), and I've been wondering if there's a terminal or a panel within VSC that acts like the Intersystems Studio Output panel, which serves both as an input and output window and allows the execution of ObjectScript commands.

Could anyone help? Thanks :)

So far, we have covered how to use ObjectScript to manage users, roles, resources, and applications. There are a few other classes in this package that work similarly to the ones mentioned above. However, these four classes are the ones everyone will have to use to manage their application security.
