WIDE CHAR error

Hello,

I'm getting <WIDE CHAR> error in one of my routines, I was thinking a corrupted data or disk out of space or no mount database but all seems to be OK?

I'm running Cache 2014.1.2 and the same routines and data works in our client main server with not problems but having the same copy in their backup server is generating <WIDE CHAR> error, some other reports works but this specific doesn't?

Thanks

Atelier & Git?

Hi,

we are trying to use Atelier and GitLab for our Software-development. Our Software has round about 1000 classes that got developed over years.

What we want to achieve is that one repository holding the complete code of one namespace. We also want to create branches to develop new small parts.

Winning in GIS competition

GIS stands for Geographic Information System.
and it's not a typical arena for Caché. But it's definitely an environment with high data volume.

You see 3 major areas

- Visual front end:
A mature area well covered by a bunch of commercial and open source products.
No need for Caché there.

I have a vendor that is sending me an Abbreviation in FT1:16.4.2 that I need to look up against a table to find the correct ID for.

FT1|1|||20180523161501|20180523161503|CG|1906551^Lipid Profile|||1||||||^^^ LAB&06CL|||Z00.00||00410^Knerr^Joel||721410||30100001^Lipid Profile|

But in my Business Process when I refer to request.GetValueAt("FT1:16.4.2") its not recognizing that this field contains information. Is my syntax wrong?

Does anyone know how to disable the auto-refresh in Healthshare, especially for Message viewer , Business process designer, DTL editor pages?

These pages in management portal refresh every 15min( i.e. as per the session time out setting) . I tried to set the following two configs to disable the auto refresh but both had no impact. 

set ^EnsPortal("DisableInactivityTimeout","Portal") = 1
set ^%SYS("Portal","EnableAutoRefresh") = 1

Thank you for your help.

Mary

I need to check if one class is a subclass of another (either direct or indirect).

For example:

Class Package.ClassA Extends %Library.Persistent
{
}

Class Package.ClassB Extends Package.ClassA 
{
}

Class Package.ClassC Extends Package.ClassB
{
}

In this example Package.ClassC is a subclass of 3 classes: %Library.Persistent, Package.ClassA, Package.ClassB.

So any of these checks should return 1:

1.1 I met a few project that their interface servers were crashed. Cutoms wanted resume server as fast as we can. their servers are running at lan,and they can't use git,there are some namesapce in the server running different service,and usualy there is only one server.

1.2 In the message,it has property in type of characterstream,as you know,the message search page doesn't support filtering with property of characterstream,so it's so hard to find the messge you want.

InterSystems SAM is a great tool to monitor your InterSystems IRIS and InterSystems IRIS For Health clusters on prem or in a cloud environment. This article describes how you can implement a customized alert handler. This is currently an undocumented and most likely an unknown feature of InterSystems SAM. With future releases it will be probably made easier to leverage this useful concept.

Good afternoon, I have working prototypes of each of these approaches. I do not have an expansive cache background.

I have a couple of projects where I am ingesting files from disk.

The name of the file contains a lot of the information I will need to reference the file in the future.

I have an incoming data partner who occasionally passes a non-ASCII character in some free text fields which is causing some downstream systems to be unable to accept the message. Ideally I'm looking for some way to just process the entire message as a data transformation applied in the business rule, as we already have a pre-processor transform to remove the PD1 segment.

Headache-free stored objects: a simple example of working with InterSystems Caché objects in ObjectScript and Python

Neuschwanstein Castle

Tabular data storages based on what is formally known as the relational data model will be celebrating their 50th anniversary in June 2020. Here is an official document – that very famous article. Many thanks for it to Doctor Edgar Frank Codd. By the way, the relational data model is on the list of the most important global innovations of the past 100 years published by Forbes.

On the other hand, oddly enough, Codd viewed relational databases and SQL as a distorted implementation of his theory. For general guidance, he created 12 rules that any relational database management system must comply with (there are actually 13 rules). Honestly speaking, there is zero DBMS's on the market that observes at least Rule 0. Therefore, no one can call their DBMS 100% relational :) If you know any exceptions, please let me know.

Hopefully a simple question.

Using the Rule Editor, I can open a routing rule and easily define an 'effectiveBegin' and 'effectiveEnd' date. I want to utilize this date feature for a "sub-rule" (i.e. rule #1) but not the entire routing rule therefore impacting all other rules. I also do not want to split and create a brand new routine rule just to send the message to the target business process. It would be ideal to keep it contained within this single routing class that was created.

REST Services Cataloging

I've been building up a REST services API, consisting of a dozen or so classes referenced from a Dispatch class, which has route mappings for the first piece of the URI. I'd like to have the Dispatch class be able to output all of the available Services, with some documentation. Is there something like a %Library resource that I could use to pull this information from each of the classes?

Thanks

Chris
