Hi -

After having seen how Atelier is working, I've decided to start learning/using Atelier for an existing project.

I've installed, and after a bit of poking around, I've managed to get a project that includes my classes, and they compile and such (these were all from an existing export), but I see that NONE of my .csp files came along despite being in the export file.

Dates with InterSystems

Do not let the title of this article confuse you; we are not planning to take the InterSystems staff out to a fine Italian restaurant. Instead, this article will cover the principles of working with date and time data types in IRIS. When we use these data types, we should be aware of three different conversion issues:

  1. Converting between internal and ODBC formats.
  2. Converting between local time, UTC, and Posix time.
  3. Converting to and from various date display formats.

The 2021.2 release of the InterSystems IRIS Data Platform includes many exciting new features for fast, flexible and secure development of your mission-critical applications. Embedded Python definitely takes the limelight (and for good reason!), but in SQL we've also made a massive step forward towards a more adaptive engine that gathers detailed statistical information about your table data and exploits it to deliver the best query plans. In this brief series of articles, we'll take a closer at three elements that are new in 2021.2 and work together towards this goal, starting with Run Time Plan Choice.

It's hard to figure out the right order to talk about these (you can't imagine how often I've reshuffled them in writing this article!) because they fit together in such a nice way. As such, feel free to go on a limb and read these in random order smiley.

Source control and the production class

When you create an Ensemble production your namespace acquires a new class definition. For example here is what the class that defines the Demo.Loan.BankUSProduction production in the ENSDEMO namespace looks like when opened in Studio:

API to import/export routines

This is an article on the InterSystems FAQ site.

1. Export API

a. Use $system.OBJ.Export() to specify individual routines to export. For example:

do $system.OBJ.Export("TEST1.mac,TEST2.mac","c:\temp\routines.xml",,.errors)

The format to specify is routine name.extension, and the extension is mac, bas, int, inc, obj.

Errors during export are stored in errors.

Under the previous python binding method (Cache) it was possible to pass in parameters, execute a class query, and fetch the result sets. I have been unable to find a way to do this via PYODBC or the Native API (perhaps I am just missing something).

My work around is to create a SQLquery string and execute it through a cursor. I would much prefer to simply execute the debugged and more secure class queries that already exist and and have been precompiled.

Any pointers would be greatly appreciated

Thanks,

Sinon

Hi,

A site has a Mirror set, and an Asynchronous DR. The disk drives for each of the instances are local disks and the databases are large (>2 TB)

The current backup strategy is started off as using Cache Backup and is still the case today, but the size and time it take t do the backup is obviously prohibitive.

Hi Developers!

There is a recent update came for developer community images of InterSystems IRIS and IRIS For Health.

This release comes with Environment variables support.

Currently 3 variables are supported:

  • IRIS_USERNAME=user to create
  • IRIS_PASSWORD=with password
  • IRIS_NAMESPACE=create namespace if doesn't exist

Here is what you can do - see below.

Start iris with your username and password created:

docker run --rm --name iris-sql -d -p 9091:1972 -p 9092:52773  -e IRIS_PASSWORD=demo -e IRIS_USERNAME=demo intersystemsdc/iris-community

We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?

Thanks

[Background]

InterSystems IRIS family has a nice utility ^SystemPerformance (as known as ^pButtons in Caché and Ensemble) which outputs the database performance information into a readable HTML file. When you run ^SystemPerformance on IRIS for Windows, a HTML file is created where both our own performance log mgstat and Windows performance log are included.
