Hi Community,

It's time to announce the winners of the annual InterSystems Grand Prix Contest 2023!

Thank you to all our amazing participants who submitted 20 applications 🔥

I have several 1GB journals from a LIVE server that I would like to inspect (eg: check which globals have been updated over the time).

Is there a simple way to view those journals using another IRIS instance ? (eg: local installation).

I have been tempted to put those files directly into the journal folder of my local installation and restart the system, however I am concerned that the transactions they contains will be restored and will corrupt the local database.

Hey Community,

It's time to announce the winners of the InterSystems Python Programming Contest 2023!

This is an attempt to run a vector search demo completely in IRIS
There are no external tools and all you need is a Terminal / Console and the management portal.
Special thanks to Alvin Ryanputra as his package iris-vector-search that was the base
of inspiration and the source for test data.

It's time to announce the Winners for January! Please welcome our awesome Global Masters Heroes!

The storm of applause goes to these developers and their great contribution to DC in January:

🥇 @Luis Angel Pérez Ramos, Sales Engineer, InterSystems
🥈 @Pierre LaFay, CEO, Ellipse
🥉 @Sylvain Guilbaud, Sales Engineer, InterSystems

Hi Community

I want a FHIR resource example that will populate allergies as displayed below, I am currently focussing on only allergies and not alerts.

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.

I am trying to set up VS Code so that it will connect to a new server running IRIS 2023.1, and I can't seem to get the setup to accept my errors. I enter all the requested information, and at the end I receive a message:

Failed to store server '$(name)' definition.

I have some databases in my cache instance that were created from an online backup file (.cbk). I would like to see the information for these databases in the Databases and SQL sections of Management Portal, but they only appear in the Classes section. I can navigate to the files in my cache instance terminal and see the CACHE.DAT files, and a check in the terminal shows that they are mounted.

This is what I see in the terminal for each database when I check to see if the databases are mounted:

%SYS>set db="/path/for/mydatabase"

how can i use git for versioning while working in IRIS.
I am having directory that i created while working in iris. How can i manage version control using git in this case.

Is it possible with vscode terminal or with a normal terminal in mac.

Work Queue Manager (WQM) is a feature of InterSystems IRIS that enables you to improve performance by distributing work to multiple concurrent processes programmatically. The idea is that you split the work into chunks, and WQM distributes the chunks across worker processes and can provide the info that the work is done.

However, recently, I got an interesting question: there's a large logical transaction composed of ~1,000,000 individual objects and SQL inserts and updates. Some updates are CPU-intensive, so the original idea was to use WQM to split an update into chunks to speed things up.

But, here's a catch: if one of the individual 1,000,000 changes fails (there's a variety of application-level checks so that it can fail, and that's not even that abnormal a behavior), the entire transaction must be rolled back. That creates a problem: each chunk must report success before committing their individual transactions, and someone must get all these reports and decide if we are committing or not.

Unfortunately, it looks like WQM does not have a bidirectional communication between workers and manager, so I suggested an approach using events:

1. Start jobs.
2. Wait for all jobs to report success using $System.Event.WaitMsg().
3. Send Commit or Rollback using the $System.Event.Signal().

When AMD published the x86-64 standard in 1999, little did they know they were inventing what would become the de-facto architecture for server CPUs. But the CPUs of today aren’t the same as ones produced 20 years back – as they have extensions for everything from Advanced Vector Extensions (AVX) to Hardware-Assisted Virtualization (VT-d).

InterSystems would like to take better advantage of these new extensions in upcoming versions of InterSystems IRIS. While our compilers are smart enough to create optimized code for many situations, some optimizations can only be turned on by explicitly cutting off support for processors that do not have that instruction set. Additionally, we are finding it increasingly difficult to maintain older CPU models to test on.

I have files of mixed types; e.g. a.pdf, b.pdf, c.txt.

I zipped them with gzip to make a.pdf.gz, b.pdf.gz, c.txt.gz.

I concatenated them into one file, all.gz.

I renamed all.gz to all.zip.

I emailed it but cannot extract in windows browser.

I have a BPL that checks if at least one of the incoming OBX 5 values exists in TestTable. If the value exists it gets passed to Operation A and if it doesn't exist it gets passed to Operation B. The lookup table has keys that range between 10 to 70 characters. However, the incoming message sometimes has OBX 5 values that are greater than 510 characters which causes the BPL to terminate and the message does not get sent to any operation.
