Hi All,

I am converting UTF-8 encoded error files to ANSI files and for that I had written below piece of code. But I am not able to get ANSI encoded files.

Code Snippets:

Set tReadStatus = ""
Set eol = 0
Set (tRecord1,tRecord) = ""
Set stream=##class(%Stream.FileCharacter).%New()
Set sc=stream.LinkToFile(tErrorFileName)
Do stream.TranslateTableSet("cp1252")
Set tNewStream = ##class(%Stream.FileCharacter).%New()
Set tNewStream.Filename="D:\Bhupi\Test6.txt"
Do tNewStream.TranslateTableSet("cp1252")
While ('stream.AtEndGet())
{
Set tRecord=stream.ReadLine(,.tReadStatus,.

Hi,

I'm using InterSystem Cache v2015.2.5 and I'm implementing a REST API and returning JSON.

Following the documentation I see examples like this

Set obj = {"destinations": ["London","Madrid","Tokyo"]}
Write obj.%ToJSON()

However, I have a compilation error 

ERROR #1054: Invalid expression : '{"destinations":' 

Is there something that needs to be enabled on Studio to allow this syntax?

Thank you,

Rui

Hi,

How Can I get sentiment analysis (positive or negative attribute) from a source or entity from iKnow REST API?

I created a custom class for a process that does some basic manipulation to an HL7 message. I'd like to be able to write some debugging to the process event log. How would I do that?

I've tried ##class(Ens.Util.Trace).WriteTrace("system","HOSP.IHE.PDQProcess","MessageHeaderHandler","Discarding input message")

but I get a runtime error when I try that. I know this is pretty basic stuff, but any help would be appreciated.

Note: there are more recent updates, see https://community.intersystems.com/post/updates-our-release-cadence

InterSystems is adopting a new approach to releasing InterSystems IRIS.  This blog explains the new release model and what customers should expect to see.  We laid this out at Global Summit at the end of the InterSystems IRIS roadmap session  and have received a lot of positive feedback from customers.

With this new model we offer two release streams:

1) An annual traditional release that we call EM (for Extended Maintenance)

2) A quarterly release that is tagged CD (for Continuous Delivery) and will be available only in a container format.

Hi Community!

Consider I have InterSystems IRIS server in a cloud and want to introduce a DR server for it.

Are there any requirements for DR server for InterSystems IRIS if it is in a cloud?

Should it be the same subnet? One private cloud?

Can DR server be placed on another cloud, say Primary on Google Cloud and DR on Azure? Are there any caveats/concerns?

Hi All!

I asked previously about the DR server in the cloud but actually, I'm curious about the backup server to use as analytics server more than for recovery in DR case.

There is a recommended practice to use an async mirror as a server for BI (InterSystems Analytics, DeepSee)

The question is if I have PRIMARY in the cloud (AWS, Google, Azure, etc) "how far" should async mirror member be placed? Same cloud, same private cloud or it doesn't matter at all for analytics purposes?

(Originally posted to InterSystems CODE by @Dmitry Maslennikov) The following code snippet outputs message header data in Ensemble. The class method "fetchExecute" runs the process, and the result is stored in the argument "qHandle":

include Ensemble
Class DAiMor.fetchMessageHeaderData extends %RegisteredObject
{
 
Query Fetch(Namespace As %String) As %Query(ROWSPEC = "Namespace:%String,ID:%Integer,Type:Ens.DataType.MessageType,Priority:Ens.DataType.MessagePriority,Invocation:Ens.DataType.MessageInvocation,TimeCreated:Ens.DataType.UTC,TimeProcessed:Ens.DataType.UTC,Status:Ens.DataType.

Is there a responsive way to detect a source code change without using a source control hook?

Update

I have my own custom unit test tool which has lots of extra functions that I find useful such as Asserting HL7 Transformers and REST targets.

I have a studio hook that will send an event signal to my test runner that will automatically re-run a specific test class or test suite, for which I have a test runner viewing page that updates with the results.

There are some environments that already have a studio class registered and I don't want to shim something in-between the two.

(Originally posted on Intersystems CODE by @Iain Bray) The following code snippet converts all indices in a package to bitmap indices. The subroutine "test" runs the code:

The data model of your solution based on InterSystems platforms constantly changes over time. But what do you do with the data that was entered before? Back then, the data was valid, but what’s happening to it now after a number of data model changes? The answer to this question can be provided by the IDP DV tool that checks the property data of persistent and serial classes according to the types of these properties. In case any discrepancies are found, the tool generates a detailed error report for the user.

I have a XML enabled persistent class and a XML representation of some object of this class (object ID is available).
How can I use XML Reader (or some other mechanism) to automatically update this object?
 

Greetings all,

I have a quick SQL question.  I am working with a class, which has a calculated property, which in turned indexed.
The calculation for this property is created based on another property value via: 
SqlComputeOnChange = attributes  - so basically every time I add a property attribute to my class, my new property 
is calculated based on some SqlComputeCode which calls some class method.

That initial setup works as designed.

Question: If my code for whatever reason gets to a ROLLBACK, does the calculated property always rolls back,
and it's index always cleared?

Hello,

We are trying to migrate all our production to new IRIS servers. To test everything is working fine, and to be able to script the process, we want to import the data into new IRIS servers using a backup file (created with ^BACKUP). But we've found that IRIS doesn't recognize Ensemble backups so we can't import it using ^DBREST  :-O

Any of you know how to import in IRIS an Ensemble backup file?

Thanks a lot,
David

 So, I think this can be done but cannot remember how.

Inbound message goes:

MSH

PID

PV1

ZIF

OBX

We want outgoing message to be 

MSH

PID

PV1

OBX

ZIF

Do I need to create a new schema to make that happen?

Thanks,

Tim

Containers

With the launch of InterSystems IRIS Data Platform, we provide our product even  in a Docker container. But what is a container?

The fundamental container definition is that of a sandbox for a process.  

Containers are software-defined packages that have some similarities to virtual machines (VM) like for example they can be executed. 

Containers provide isolation without a full OS emulation. Containers are therefore much lighter than a VM.

EnsLib.HL7.Message.cls provides many API methods for manipulating an HL7 message.  RemoveSegmentAt(), for example, can be used to remove a segment by path or index, but only one segment at a time.   There may be times that you'll need to remove all segments within a group or even many groups of segments from the HL7 message.  Surely you can iterate through each segment in each group and remove them one by one, but there's a much easier way. 

With just one command, like below, you can remove all OBX segments in an ORU_R01 message (msg):

Set tSC = msg.SetValueAt(,"PIDgrpgrp(1).ORCgrp(1).

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter. 

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

2) Can we import an existing Cache database into IRIS and convert its ObjectScript code into Java, Python whatever?

Hi,

Need your help on executing  ##Class(Backup.General).ExternalFreeze() and ##Class(Backup.General).ExternalThaw()   operations in

Atelier REST API setup. Please provide us example code if any.

I need to write a script to answer a couple of fairly simple questions:

1) What is the current routine DB (name and location) for this namespace?

2) What is the current data DB (name and location) for this namespace?

3) Is global ^ABC mapped to a different location than the default data DB?

Can anyone point me to some system APIs that would allow me to answer these questions?

Thanks!

Ben

Hi,

Trying to build a passthrough based on ASTM . I have created 2Way TCP/IP Business Service and specified a PORT (as Adapter Settings). The Source system is broadcasting from  IP 20:30:100:100 , Port 10000 . Ensemble is on 20:40:40:100 , What is the possible change that I have to implement to receive this broadcasted messaged ? . Should the Ensemble Server be on the IP range to receive the broadcast ? 

Many Thanks,

Hello,
Fellow community members, here is an extendable / re-usable / generic pub-sub model.
An initial calling service reads a CSV file, parses through all records and transforms it to a generic JSON message.
The message is then transported via a pub-sub business process to the end-points Targets (business operations)
as configured for the subscribers for each Topic as demonstrated in the image below.

Steps and flow to implement this are as follows
1. Service 
a. Read a csv file, loop through all records

Hi,

I ran into the Issue https://hibernate.atlassian.net/browse/HHH-10620. The workaround  described at https://community.intersystems.com/post/support-java-hibernate-5 worked for me. I'm using Hibernate Version 5.3.2.Final.

It would be nice if someone from InterSystems could fix the the problem in Hibernate. That was mentioned in https://community.intersystems.com/post/support-java-hibernate-5 but it doesn't seem to have happened.

InterSystems IRIS Data Platform™ version 2018.2 is now available as a preview release.  This is the first release in our new quarterly continuous-delivery (CD) release stream.  (Check out the announcement about InterSystems’ new release cadence for InterSystems IRIS)

Hi,

Most of my classes are mapped from Globals. I want to access Cache classes from a BI software through ODBC connection.

'Last update' information does not exist in most of the classes. My question is whether there is a 'last update' timestamp that is automatically generated for each line in classes I can extract to external systems?

Thanks

Hey Developers!

New session recording from Global Summit 2018 is available on InterSystems Developers YouTube Channel:

Using Blockchain with InterSystems IRIS

Can anyone tell me how to discover in ObjectScript the operating system and operating system version that Caché is actually running in? (Not the operating system the build was compiled for.)
