Hi Community!

We are pleased to invite you to the upcoming webinar in Spanish: "How to implement integrations with .NET or Java on InterSystems IRIS" / "Cómo implementar integraciones con .NET o Java sobre InterSystems IRIS" on May 20 at 4:00 PM CEST! 

What will you learn?

If you work with interoperability productions of InterSystems IRIS or Ensemble, no doubt you are familiar with the Message Viewer page. The page supports filtering messages according to filter criteria you enter in the Basic and/or Extended Criteria sections. Extended Criteria conditions are specified as property-operator-value triples. Once you click Search button, such triples become WHERE clause conditions of a generated SQL query executed against message header/body tables.

As a side note, one can view recently generated message queries by following the instructions listed in the doc.

Hi, 

iris version: IRIS for UNIX (Ubuntu Server LTS for x86-64 Containers) 2019.4 (Build 383U) Fri Dec 6 2019 08:49:54 EST

os: Ubuntu 18.04 LTS

memory: 16G

Disk: 256G SSD

Iris config: default.

soft/hard limit: 65535

I build follow simplest flow to do performance test.

1. create A EnsLib.HTTP.GenericService name it IncomingHTTPService listen on 9980

checked create connection per request

Keepalived = 0

Qsize = 1000

2. create A EnsLib.HTTP.GenericOperation name it OutgoingHTTPOperator to connect localhost:8080(it's a nginx server serve a static html page)

3.

I have the variable with literal.

Can I understand with ObjectScript that the literal is:

%String, 

or %Integer,

or %Date,

or %Double,

or %Numeric?

What I'm looking for could be:

set variable="To be or not to be"

USER>w ##class(utils).GetType(variable) 

%String

set variable=42

USER>w ##class(utils).GetType(variable) 

%Integer

Hi Developers,

Enjoy watching the new video on InterSystems Developers YouTube:

⏯ Resilient Deployments in the Cloud

Most of us are more or less familiar with Docker. Those who use it like it for the way it lets us easily deploy almost any application, play with it, break something and then restore the application with a simple restart of the Docker container.
InterSystems also likes Docker.The InterSystems OpenExchange projectcontains a number of examples that run InterSystems IRIS images in Docker containers that are easy to download and run. You’ll also find other useful components, such as the Visual Studio IRIS plugin.

Has anyone recently deployed the cache-git-studio plugin from Github repo?

In particular, I see that this plugin is installed at the namespace level, so it appears for each user have their commits in their own name, they must all be running a locally installed cache server when doing their dev work. I suspect that is the preferred way.

In my organization they are currently just accessing a remote cache server from Studio. In that scenario, it looks like it would be one installation of git for the whole team. and thus only one shared git user.

Hi community,

I need to write an SQL query  to fetch a random record from a table, that table has millions of data.

In postgresql, for example, there is a RANDOM() function to do something like that:

SELECT column FROM table
ORDER BY RANDOM()
LIMIT 1

Is it possible to do something like that in Caché?

Thanks in advance

The Caché System Management Portal includes a robust web-based SQL query tool, but for some applications it’s more convenient to use a dedicated SQL client installed on a user’s PC.

SQuirreL SQL is a well known open source SQL client built in Java, which uses JDBC to connect to a DBMS. As such, we can configure SQuirreL to connect to Caché using the Caché JDBC driver.

Finding Caché’s JDBC driver JAR

The JAR file containing the Caché JDBC driver is installed automatically by the Caché installer when installing a full Caché instance or when installing client components only.

Hi Developers,

Please welcome the new video specially recorded by InterSystems Product Manager @Bob Kuszewski for the 3rd InterSystems Online Programming Contest on InterSystems IRIS Native API:

⏯ Using the IRIS Native API GitHub Template

What’s the contest about?

In the last year, InterSystems added and expanded Native APIs for Java, .NET, Python, and Node.js. The Native API provides high speed access to globals, the ability to instantiate and use ObjectScript objects, and fine-grained control over transactions.

I known ensemble builtin support xml and hl7 document  searchtable , is it also support searchtable on json document?

Is there a way to force a failover from the primary mirror member to the backup member without forcing down the primary (which happens with ##class(SYS.Mirror).BecomePrimary())? What I'm trying to simulate is a network isolated condition on the primary.

I have been using %Net.FtpSession and while it works, its handling of file/directory listings from an FTP server is less than ideal and, while this is due to the FTP protocol itself, the class could be written to handle this as would an FTP client such as FileZilla and command line/class FTP handlers for other languages.  I was wondering if anyone knows how the Ensemble adaptor works with this in case it provides code that would help, though the source does not seem to be available.

Hello Community, 

I want to secure a SOAP Webservice (an EnsLib.SOAP.Service one, if that matters) adding a SSL/Username Policy to it. As im not sure how detailed my request here should get, ill try giving a detailed as-is description of my setup, what I've tried, how I tried to test the connection and what problems including some logs I ran into. 

As a small foreword: I'm pretty new to the whole security aspect of intersystems and soap itself. 

System:

I've tried it on 2 different systems with pretty much the same result: 

1. IIS Server with a 2 System-Mirror Healthshare 2018.1.

Hello,

We are trying to connect to a database through a JavaGateway.

We observe that the JavaGateway reports:

Failed to start the Java Gateway server: ERROR #5002: Error de cache: <UNDEFINED>zGetJavaVersion+22^%Net.Remote.Service.1 *versionWithPrefix

We have checked that we do have the Java Home set:

/usr/java/jdk1.8.0_65

And we have seen the java files in the server:

We have read the code where the exceptions being raised:

/// Returns the numeric part of the Java version string (e.g. 1.8.0.1)
/// Rules of how the complete version string is formatted can be found here:
/// http://www.oracle.

Hi!

Is there a method in a persistent class that can return the current number of records/persistent objects in it?

If I set up a Mirror and add a new database to the mirror, do I need to create the new database on every single member of the mirror or will it automatically appear on Mirror members? How about HSCUSTOM database, which already got created when installing IRIS?

Preview releases are now available for the 2020.2 version of InterSystems IRIS, IRIS for Health, and IRIS Studio!

InterSystems IRIS Data Platform 2020.2 adds support for TLS 1.

I am trying to create REST API following these instructions:  https://docs.intersystems.com/irislatest/csp/docbook/Doc.View.cls?KEY=GREST_apimgmnt

However it does not work.

I tried downloaded the v2.0 schema.json of the OpenAPI specification and pasted it on Postman with the parameters as speicifed, but I get this error message back:

{
    "msg": "ERROR #8738: Correct OpenAPI 2.0 version was not specified: . <$.swagger>\r\n  > ERROR #5490: Error running generator for method '%OnCompile:TasksRestApp.spec' \r\nERROR: %REST.Spec.cls(%OnCompile) of generated code compiling subclass 'TasksRestApp.

Hello all, I have a question about constucting thousands of clones, and scope.

In my code, I'm looping through a database, say 200k+ objects, and creating a clone of each object (we need to evaluate a modified clone of the object, but not account for what's on disk).  

I see this a lot in the documentation:

" Whenever you set a variable or object property to refer to a object, its reference count is automatically incremented. When a variable stops referring to an object (if it goes out of scope, is killed, or is set to a new value), the reference count for that object is decremented.

Hi folks!

When I start IRIS in docker every time I do the following:

$ docker-compose up -d --build

$ docker-compose exec iris iris session iris

USER>zn "NAMESPACEINEED"

Is it possible to have an open terminal command connect to a particular namespace?

Hello guys, 

I have used the Studio SOAP wizard to generate some webservice client classes and amongst those classes:

Class RMH.SOAP.s0.Output Extends (%Persistent, %XML.Adaptor) [ ProcedureBlock, SqlTableName = _Output ] {
...
Property Value As %GlobalCharacterStream(XMLNAME = "Value");

And the caller looks like

Class RMH.SOAP.SoapTreeSoap Extends %SOAP.WebClient [ ProcedureBlock ] {
...
Method Run...(Tree As %String, Inputs As %String, Debug As %Integer) As RMH.

Hi Developers!

As discussed in previous parts of Package Manager stories to turn your IRIS application into a deployable package you just need to introduce the module.xml file into the root folder of the repository and describe all the resources.

I’m pleased to introduce you to a new project template on Open Exchange which contains examples of how to make different types of resources of your InterSystems IRIS application a part of the ObjectScript package and so make the deployable ObjectSctipt package.

Let's see how you can describe your application resources using this template project as an example.

See the details below.

So, I was doing a debug test on a routine, and tried to open a file (yes, it does exist) as so:

s file=##class(%File).%Open($$$airfile,"R")

And, I got the above-mentioned error. It begins with "cn_iptcp://localhost:56775/%Stream.Object.1.INT" in case the port means anything.

This is a single-license version of Cache 2017.2, which I installed about three years ago. You would think I'd have the .INT files, but I don't. Oh, one other oddity: I can't seem to compile the routine, despite having admin privs for the machine. It's Windows 7 64-bit.

Any help is appreciated.

Hi, if you develop production with HealthShare, you may have noticed there is a nice tracing feature available - HS.Util.Trace.Operations. This feature allows visually tracing debug information, in structured way. It complements good old logging macros like $$$LOGINFO, $$$TRACE and alike.

I use this feature a lot. However, it has limited functionality, it works nice with classes that extend XML Adapter, streams or data types, but it doesn't work well with arbitrary objects that do no extend from XML Adapter.

I decided to implement a subclass of the trace helper class HS.Util.Trace.
