We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).

Hello,

Is it possible to write global output values to STDOUT, in a similar way to how csession can take routine intput, like below:

(In Cache Terminal)

%SYS>d ##class(%SYSTEM.License).ShowSummary()

License Server summary view of active key.

Distributed license use:

Current License Units Used = 1

Maximum License Units Used = 1

License Units Authorized = 200

Local license use:

Current Connections = 1 Maximum Connections = 1

Reviewing a client console log, I am finding the message:

Terminal disconnect: The specified network name is no longer available.

This message is repeated in the log dozens of times per day over the last month. The client has not raised a concern and our monitoring has not detected any issues with client ops. The client is not aware of any recent changes with their apps. I am not familiar with this message and whether this message is benign or whether there is any action required,

Hi,

I have a method that has multiple parameters and is normally used from other classes in ObjectScript. Most of the parameters have default values. Withing the server code that's perfect. In some areas I can call myMethod(,,"sometext") or myMethod(tVariab) and thats fine... I use it as it's required in each place.

But now I want to expose it as a REST service so I need to buld a kind of wrapper., another method in a REST dispatcher class that will receive the parameters in a JSON object and will call the server method already implemented. Something like:

Hi Developers!

InterSystems IRIS stores everything in globals and if we use ObjectScript classes to persist data class documents globals it uses in storage. But if you use globals for calculations, temporary storages, for special indexes or for some other purposes - how do you document it?

Possible options which come to my mind:

1. Macro

#define Array ^MyGlobal

usage:

s $$$Array(1)=1

2. Class parameter

Parameter Array ="^MyGlobal";

Usage:

Tools to find a class

Good morning,
I'm working with a persistent data class and need to know which classes are evoquing it.
Is there a tool in the system to do it, similar to use the F12 key to follow a class?

Hi,

I'm trying out VS Code with IRIS for Health 2023.2 (not available in above dropdown) in a local container. I can open read-only files in the Objectscript viewer and have a local folder connected to the correct namespace. However, when I make changes and try the "import and compile" option, I get:

ERROR #16006: Document <filepath> name is invalid

The first four chars of <filepath> appear to have been truncated

Here is my settings.json

{

"security.workspace.trust.untrustedFiles": "open",

Hi

I was wondering whether anyone can help I would like to know what is the underlying method that is used for exporting lookup tables from within studio. I would like to do this programmatically. The export function provided with Ens.Util.LookupTable is not compatible with studio.

Thank you.

Kind Regards,

Salma

Clean up code after compile

After upgrading I ran a $SYSTEM.OBJ.CompileAllNamespaces("u"). What I got in return was kind of a shock.

In reviewing errors I am seeing code being referenced but no longer applies. It is referring to stuff that might of been defined in the Context , Formal Spec ,Thread , etc.

ERROR #5373: Class 'osuwmc.CPD.DataStructures.TblPharmacyDEA', used by 'osuwmc.CPD.BusinessOperation:SelectProviderTempDEA:FormalSpec', does not exist

Hi Guys, I'm resending this because I sent on the weekend and looks like it has not been noticed much

I'm not that familiar in using Javascript in Zen pages, so basically we have a priting utility (app) that requires us to add a bit of JavaScript call to facilitate printing from our Zen pages as below:

So I added XData link pasted the required script, is this the correct way?

InterSystems has corrected a defect that could lead to invalid backups on Windows platforms. The defect causes upgrades to disable the EnableVSSBackup setting. By default, EnableVSSBackup is enabled (value set to 1) and the upgrade sets its value to 0. Windows VSS backups taken with this setting disabled may contain invalid CACHE.DAT files.

This problem is limited to Windows platforms on the following versions:

  • Caché and Ensemble 2018.1.0, 2018.1.1, and 2018.1.2
  • HealthShare Health Connect (HSAP) 15.032 on Core versions 2018.1.0, 2018.1.1, and 2018.1.2
  • HealthShare 2019.1 (Unified Care Record, Patient Index, Health Insight, Personal Community, and Provider Directory) on Core version 2018.1.2
  • HealthShare 2018.1 (Information Exchange, Patient Index, Health Insight, and Personal Community) on Core versions 2018.1.1 or 2018.1.0

The defect only occurs if you are upgrading to a version listed above. Once you have upgraded to an affected version, you must manually enable the setting; otherwise, it will be disabled on future upgrades, even when upgrading to versions containing the correction.

For customers using Windows VSS backups, InterSystems recommends enabling this setting on any 2018.1 instances of Caché or Ensemble. Once you have enabled the setting, future upgrades (including to affected versions) will preserve its value.
