It's a wrap! All of the focus sessions have aired now. Of course, all of our 102 pre-recorded focus sessions are available on-demand now, so you can watch any and all of them, even if you missed the opportunity for live Q&A.

Hi All,

Can you please guide me on how to restore the .cbk file from the 2015 Cache version into the 2017 version or any other versions of Cache or IRIS software? I have a new instance on my server. It's an entirely new server. I have a .cbk backup file. I want to restore the backup file into a new namespace which one I will create on my new server. When I am trying on ^DBREST utility, I am getting "This is not a Cache Backup File" this error.

Please advise on this. It's a bit urgent.

Thanks,

Arun Kumar.

I've been impressed at the quality of the questions at our live Q&A sessions!

These sessions were meant as a way for you to ask anything you want (I call this playing "stump the chumps").

They're all recorded and available for review later; here're the links:

Those of you who are following the FullStack competition here in the Developer Community will know that I submitted an entry named qewd-conduit. I wanted to summarise why I think it's something worth you taking a bit of time to check out.

qewd-conduit uses the Node.js-based QEWD framework alongside IRIS to implement the back-end REST APIs for something known as the RealWorld Conduit application:

Hi All,

I'm being asked if I can set up a AWS EC2 containerised version of IRIS and a separate AWS EC2 installation of Apache to serve IRIS web files.

Creating the Apache EC2 and containerised IRIS EC2 is the simple bit but getting them both to talk to each other does not seem quite so simple and I cannot find any documentation to describe how this can be achieved.

Has anyone else managed to achieve this?

$LIST string format and %DynamicArray and %DynamicObject classes

IRIS, and previously Cache, contain several different ways to create a sequence containing a mixture of data values. A data sequence that has been available for many years is the $LIST string. Another more recent data sequence is the %DynamicArray class, which along with the %DynamicObject class, is part of the IRIS support for JSON string representation. These two sequences involve very different tradeoffs.

Hey,

I have a value in epoch time in which I need convert in order to be able to lookup a table that has dates in YYYY-MM-DD HH:MM:SS format

I thought the below would work but it is not.

select COUNT ('Arrival Time') FROM dbo.table where 'Arrival Time' < DATEADD(ms, CONVERT(int,LEFT(1603173432000, 20)), '1970-01-01 00:00:00')

Presenter: Anton Umnikov
Task: Identify your slowest SQL queries and tune them for better performance
Approach: Use InterSystems’ query profiling and analysis tools. Discuss how system configuration can affect performance

This session will show you how you identify the weakest link in your application SQL and introduce you to the fine art of tuning those queries. To do this we will take a look at InterSystems query profiling and analysis tools, as well as how system configuration can impact SQL performance.

Problem: Obscurity on how our SQL engine works

Today we are pleased to publish a new extension pack for Visual Studio Code. This pack provides a convenient way to install and manage a set of extensions which together make VS Code a great tool for ObjectScript developers.
