REST service with 11G Sql

Hi, I asked last week and they gave me some little tips. But the truth is I still can't carry out this "Project".

I must perform a REST service, using Oracle 11 database. Eh tried anyway to achieve this.

The purpose is to make a REST service, using the database provided to me and use the procedure that is already created.


According to what I read, I made the connection via JDBC and I had no major problem

Hello everyone,
It is my first post in the community. Very recently I started working using IRIS, creating services with Cache.
Today they gave me a new task and I'm really lost.

How can I use an oracle database to create services using iris?

Throughout the day I was looking for a guide to use a remote Oracle database. but unfortunately I only managed the connection in SQL Gateway

Keep Alive Packet

does Health Connect have an out of box setting to send some type of "Keep Alive" packet?  This is for a TCP connection.  I have a vendor that will disconnect from the engine if there is a 2 hour idle time.  would like to send something across every hour (if its idle) to prevent the disconnection.   I'm assuming this may be something custom that needs to be created, but thought I asked the community first.

Greetings community. I would like to know how to migrate a BD in production to a local environment. When I have a system in production (BD Sql Server) what we do is mount a local copy to do the analysis with the data and not occupy resources of the system in production. My question is: How do you do it with Intersystems technology?

Common Testing Frameworks.


I'm after feedback and comments on the sort of tools and approaches the wider InterSystems community uses for QA Testing applications written in Cache/Ensemble or IRIS.   I am aware of the %UnitTest package, and understand how that works... but:


- Do you use an alternative or framework built around this native Unit Testing tool ?

- What is your experience with %UnitTest if you use it ?

- Is there a tool you would recommend for your UI (I know this is not specifically an InterSystems' related question)

As a normal IRIS user how can I view who's made changes to a process?  There are over 10 people on my current team and it would be amazing to be able to click on a process or rule and see who created it or who made the most recent changes.  I'm not seeing anything in the documentation.  Journaling doesn't seem to capture that information either.

I'm trying to create a new Record Map but I keep getting a ZEN Exception error.  I actually go this to work the very first time I did it and have a record map.  But I need to do more.

I'm working on my local machine so I can grab a CSV (or txt in this case as it's pipe delimited) from the local directory.  I pick the file I want to use but when I click OK i get a popup and the following error:

How do you search with REST

The question is pretty much in title. I'm developing a REST API, it has a search endpoint with 10 optional parameters. How do I pass them and stay RESTFul?

To ease the question a bit let's agree that:

  • all parameters are AND parameters, user can't make combos, ORs, etc. User can only provide values
  • all values are integers so I don't have to think about URL limits
  • all values are atomic
  • all conditions are about equivalency

Some options I know of:

1. URL parameters.

I'm trying to convert a CSV inbound to an HL7 MFN^M16 outbound.  I know I'm using book information as the CSV but I don't think that matters.  Please let me know if that's incorrect. 

My service is reading the file in just fine and when I don't have a DLT transformer the raw message passes through to outbound file folder just fine.  However, when I include a basic DLT that simply copies a couple of fields over I get the "Ens.StreamContainer" error.  Everything also seems to be good in the Record Mapper.

Hi all,

I recently discovered the Monitoring Activity Volume feature in IRIS and I was amazed by it. So, I put it to work in one of our productions. It is nice how easy it is to set up and all the possibilites that came with it.

But there's something weird: the numbers. Actually, one of the BP is stating a time of more than 6 seconds to process:

Is there a way to set null in dynamic object without using %Set methods?

I have this method and I need to set NULL as, well, null and not string.

ClassMethod node(name) [ CodeMode = expression ]
    "content":($case(##class(%Dictionary.ClassDefinition).%ExistsId(name), $$$YES:"mycontent", $$$NO:"NULL"))

 I have two local instances:

  • IRIS for Windows (x86-64) 2018.1.2 (Build 626_3U) Wed Jun 12 2019 19:07:59 EDT
  • IRIS for Windows (x86-64) 2019.1 (Build 510U) Thu Mar 14 2019 14:13:37 EDT

I'm using Java Gateway to talk to external system.

Both instances are using the same:

  • jar
  • generated class
  • java version

They are calling the same method with this java signature:

Just wondering if anyone knows if there is a way to get daily emails or alerts about changes to a cache database.  I know that all of that information is contained within the journal files, just wondering if there is a way to bundle it up each day and send it off for auditing, etc.

Any solution where a plain-text/readable format of changes to the cache database could be sent or stored for review would solve the issue.

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:

Hello Everyone

I'm trying to open an XML that I get inside a GZIP file.
However, I can only open the contents when I save the file to a folder.
I would like to know if there is a way to get the contents of XML without saving the GZIP in a folder.

The code below is functional, however, you are saving GZIP before you can get the contents of the XML.
