Hello.

For debugging purposes I sometimes need to display stack information to the current device or save it (to a global for example).

There is this snippet offered in documentation:

ClassMethod StackToDisplay()
{
    For loop = 0:1:$Stack(-1) {
        Write !, "Context level:", loop, ?25, "Context type: ", $Stack(loop)
        Write !, ?5, "Current place: ", $Stack(loop, "PLACE")
        Write !, ?5, "Current source: ", $Stack(loop, "MCODE")
        Write !
    }
}

And to save stack to a global there's always an exception method:

Get columns dynamically?

In MSSQL I think you can do something like this:

select *
from HS_IHE_ATNA_Repository.COLUMNS
where TABLE_NAME='Aggregation'

How can I do this in Cache SQL?

[%msg: < Table 'HS_IHE_ATNA_REPOSITORY.COLUMNS' not found>]

A customer is using Caché online backups and needs to automatically purge the cbk files with a scheduled task.

This is a wheel has been reinvented uncountable times already and I know somebody out there has a well written, extremely robust version that has already stood the test of time.

Does anyone have a nice routine/class/task for purging old Caché backup files?

Git and Atelier

Hi,

I'm in the process of trying to convert my team to a Git-based workflow for source code version management (we use Ensemble and HealthShare, but build a lot of customizations on top). We are having a hard time working with Atelier in this regard for a few reasons:

CLS location from INT code

Given location in INT code, as Cache usually reports on error (zWriteReport+25^SomeFile.1), is there any programmatic way to determine corresponding place in original source code?

Hi all - I'm running a Zen page that inherits from %Zen.Component.page, and I'd like to step through code and debug it. Is this possible, and how?

I've tried to attach to a process that I think is mine (it has my internal IP address) but is using "Unknown User". Any ideas on where to start debugging the page -- this page calls lots of other pages. I'd thought I'd start at the home page.

Perhaps I need to navigate to my page that I want to debug, and attach at that point.

Any info on the debugger in this atypical use is appreciated.

If I wanted to build a web-based dashboard that monitored various HIE transactions where would I start?

Examples of measures would be Provide & Registers by Facility, Patient Views by facility or even PHR related data.

I have a successful POC that uses nodejs, html and SQL but I think it makes more sense to use Intersystems technology all the way around, I just don't know where to begin.

Hello,

When we need to create a utf-8 encoded XML file, we use the Charset property of %XML.Writer:

set writer=##class(%XML.Writer).%New()
set writer.Charset="UTF-8"

How can we create regular txt files with such encoding?

Our Cache Installations are 8 bit and not unicode.

Thanks,

Hello, I'm new to Ensemble, and my first task is to become familiar with the Production and create a basic outline of it for the users to view (which servers, where are the input files, where are the output files, how many records...). What are the Production tables? I'd like to start there.

Thanks,

One aspect of source code management is how to deal with the almost inevitable need to upgrade your Caché or Ensemble platform to a newer InterSystems release.

It's long been my experience that InterSystems does a very good job of maintaining backward compatibility. Code that works correctly on, say, 2012.1 is very likely to work correctly on, say, 2015.2 without any modification.
