One of the most important tasks of dashboards is, on the one hand, to help you perceive data in an aggregated form, and, on the other hand, not to lose the depth of immersion in the data if you need this. One of the tools that help us achieve this result is drill down. It enables us to display several hierarchical levels of data, from aggregated to detailed.

Successful Troubleshooting

During the last weeks, I was working on various issues and problems related to SW development.
I found that quite often problem analysis was mostly chasing issues just on the surface
but not really attacking the deeper reasons of the problem and follow the consequences.
It's like the doc that stops your leg bleeding but doesn't see that it is broken.

Hey everyone.

I have been revisiting our backup strategy, and spotted that IRIS supports VSS (Volume Shadow Copy Service) in Windows. This is quite attractive as an approach, as it automatically calls the external freeze and thaw commands.

However when calling these manually, there's quite a few parameters that can be set, and the documentation around VSS only states that the freeze/thaw commands are called.

Is there a way of controlling the parameters used, or at the very least know what the defaults are?

All,

I'm using Cache 2014.1 in an openVMS environment.

If I have multiple RMS files to clean up, for example.

!DIR MEMBER_EXTRACT.*;*

MEMBER_EXTRACT.CSV;2 MEMBER_EXTRACT.CSV;1
MEMBER_EXTRACT.PROC;1 MEMBER_EXTRACT.TXT;3
MEMBER_EXTRACT.TXT;2 MEMBER_EXTRACT.TXT;1

S FILE="MEMBER_EXTRACT.*;*"

Do ##class(%Library.File).ComplexDelete(FILE)

What are the best steps for troubleshooting printing to a Windows printer from Cache. The printer has been configured in the Windows Printer Manager and has been able to print a test page (from the windows print manager).

The device has been configured in Cache -> Sys Admin -> Config -> Device Settings -> Devices with properly formatted |PRN|printer device name and "W" for open parameters and 101 for Alias.

Running TuneTable accounts among other the parameter named Block Count. In documentation, we see that this is an approximate numbers of 2K-blocks in which SQL-maps are stored. Databases in recent Cache doesn't support 2K-physical blocks so SQL-blocks are not physical blocks as it seems. So two questions:

- what are these blocks?

- how knowledge about count of blocks can help in SQL optimization?

I am having a problem when using atelier on my instance, which I just synched from perforce on latest and then did a built

I am getting the error
ERROR #5880: Unable to create source control class: %Studio.SourceControl.ISC [zSourceControlCreate+17^%Studio.SourceControl.Interface.1:%SYS]

every time I want to open any class or routine from %SYS namespace in the Server tab.

Did someone had the same issue?

Starting out with ObjectScript, it is really exciting, but it can also feel a little unusual if you're used to other languages. Many beginners trip over the same hurdles, so here are a few "gotchas" you'll want to watch out for. (Also few friendly tips to avoid them)

NAMING THINGS RANDOMLY

We have all been guilty of naming something Test1 or MyClass just to move on quickly. But once your project grows, these names become a nightmare.

Quick sample database tutorial

Introduction

This is a simple tutorial on the quickest way I found to create a sample database for any purposes such as testing, making samples for tutorials, etc.

Creating a namespace

  1. Open the terminal
  2. Write the command "D $SYSTEM.SQL.Shell()"
  3. Write "CREATE DATABASE " and the name you want for your namespace.

Now you have a new namespace in a faster way than creating it from the Management Portal - which of course offers way more configuration options.

Hi I am getting this message for some databases but not for others: This database is mounted as read-only due to 'Failed to access iris.lck file'! and not for others on Google Cloud community non-health edition.

For example this default database displays the message: Name IRISLIB Directory /usr/irissys/mgr/irislib/

But this default database does not: Name IRISSYS Directory /ISC/dur/mgr/

Creating Portlets in DeepSee

What is a portlet?

The simple answer is: a custom widget. A portlet can exist by itself on a DeepSee dashboard, it can be used along side standard DeepSee widgets, or along side other portlets. The rendering of the custom widget is completely user defined. This means you can embed a web page, create a form to perform any sort of action needed based on the data on your dashboard, use third party charting libraries, or simply display data from outside of a DeepSee cube.

How to write the home address right?

How Tax Service, OpenStreetMap, and InterSystems IRIS
could help developers get clean addresses

Pieter Brueghel the Younger, Paying the Tax (The Tax Collector), 1640

In my previous article, we just skimmed the surface of objects. Let's continue our reconnaissance. Today's topic is a tough one. It's not quite BIG DATA, but it's still the data not easy to work with: we're talking about fairly large amounts of data. It won't all fit into RAM at once, and some of it won't even fit on the drive (not due to lack of space, but because there's a lot of junk). The name of our subject is FIAS DB: the Federal Information Address System database - the databases of addresses in Russia. The archive is 5.5 GB. And it's a compressed XML file. After extraction, it will be a full 53 GB (set aside 110 GB for extraction). And when you start to parse and convert it, that 110 GB won't be enough. There won't be enough RAM either.

Hi Guys,

The Installer Manifest has the option to modify the production level settings for AutoStart but is there a way to change settings such as ActorPoolSize and other settings? What would the format be to change such a setting to change the ActorPoolSize to 2?

<Production Name="MyProduction">

??????

</Production>
