Hi, 

I can't work out how to use the Cache CA Server to process certificate request from external clients!

We are setting up an interface where we use SSL/TLS 'Mutual Authentication' to allow a client system to securely transmit document to  our server.

InterSystems IRIS OAUTH classes explained

In the previous part of our series we have learned about configuring InterSystems IRIS to act as an OAUTH client as well as authorization and authentication server (by means of OpenID Connect). In this final part of our series we are going to describe classes implementing InterSystems IRIS OAuth 2.0 framework. We will also discuss use cases for selected methods of API classes.

The API classes implementing OAuth 2.0 can be separated into three different groups according to their purpose. All classes are implemented in %SYS namespace. Some of them are public (via % package), some not and should not be called by developers directly.

We are in the process of setting enabling SSL on a soap web service exposed via InterSystems, but are running into trouble. We have installed our certificates on our webserver (Apache 2.4) and enabled SSL over the default port 57772. However, we now get an error when sending a soap message to the web service (it used to work over http). Specifically the CSP gateway refuses to route te emssage the soap web service:

Hey all! I'd like to collect some feedback regarding searching for messages using the Message Viewer. I'd like to find out what things regarding the Message Viewer you all in the community have found difficult/confusing/poorly documented. This can of course include things that you don’t know how to do yet, but would like to learn about.

For an example, I’ve had issues searching through messages containing SDA for specific text fragments, because my searches always timeout or don’t return any matching messages.

Now that 2017.1 has been released, any indication when we can look forward to the next Field Test starting?

Update on 27-Apr-2017: the 2017.2 FT for Caché and Ensemble is now available via this page.

Update on 02-May-2017: announcement posted here.

I am looking for a way to deploy production changes (code and/or production configs) via script or some other systematic way other than the Ensemble/Deploy page in the Management Portal. My goal is to store these configurations in Subversion, then have a piece that can pull the XML from source control and deploy it to a given server. Is there some kind of script that I can run on a given server to perform this deployment? If so, I can tie it up with Subversion using another tool that I have access to.

If it helps, we are running Cache 2016.1 (HealthShare 15.01) on Red Hat Enterprise Linux 7.

I'm asking this best-practices question on behalf of a customer.

They have a Caché-based application, and an Ensemble production deployed in front as an ESB to provide web service API access to the back end application. They're looking for a best practice approach for the scenario where the Caché back end is calling a third-party web service. Should that go through Ensemble too? It's sort of a philosophical design question/debate.

InterSystems is pleased to announce the Field Test release of Caché and Ensemble 2017.2.0

The entire product team at InterSystems looks forward to hearing about your experiences with this latest version of our Data Platform products.

You can get this release from the Field Test portal.

Hi I'm hoping the community will once more help me out with a question!

Right I have a production that takes an attachment from an email and processes it, sending out a hl7 message at the end. This works ok.

Now I just need to take the email and send it back out to a 'backup' email address, basically giving
a) A backup incase there is a problem with the email or something else further down the line.
b) A log of the emails receieved.

So I thought the best thing to do is have an operation with an email adapter and to send that my message.

That gave me some code that's basically like this.

Prompted by this post about accessing a global at its original location after you have changed a mapping, here's a tip about one specific dropdown in Portal that's sometimes useful.

Please let me know in Intersystems Ensemble Prodn, where the configuration setting changes gets stored ?

Can you connect to FHIR through ensemble or do you have to have HealthShare to connect to FHIR services?

Folks

1) What's the correct way to check for an existence of a segment?  So far I have been doing this by checking to see if a required field is non-null, and this seems to work but is a bit clumsy. In this case, it’s an X12 message being checked in an IF action in BPL:

              request.GetValueAt("NTE(1):Description")'=""

Or in a DTL, to see if a Z segment exists:

              source.{ZEF:Counter}=1

2) I have a case where I need to change from an external date format (YYYYMMDD) to internal (+$H) for a DTL to create a new object (and then persist it later). I am using:  +.

If your application is raising <PROTECT> errors and you're finding it hard to work out why, here's a way to get additional information.

First, if auditing is not already enabled, turn it on:

Then use "Configure System Events" (highlighted above) and locate the event named %System/%Security/Protect. In the screenshot below I used the Filter field to do this (type "protect" - highlighted below - and press TAB):

Notice that the Enabled column shows a value "No". By default <PROTECT> errors are not logged in the audit.

I am unable to find any classes that will return the status of all the services in a production. Is there one available?

I am attempting to do two things with the mime types.

Collect the mime type from a stream(%FileBinaryStream) using this syntax: myCONTENTTYPE=stream.GetAttribute("Content-Type")

However, myCONTENTTYPE always comes in empty.

Set the CONTENTTYPE PARAMETER in the OnPage ClassMethod of a ZEN page, using this syntax: s ..#CONTENTTYPE=myCONTENTTYPE

However, I cannot seem to get the correct syntax.

I would appreciate any and all help. Thank you.

Design a production in a development environment using best practices. 

I have built an Ensemble SOAP service (EnsLib.SoapService.Service) as a business service which accepts soap requests from another application. To secure the traffic between the SOAP service and the application i'd like to enable SSL. I see that in the management portal I can upload the certificates, chains and keys and save them as an SSL / TLS configuration. However, it is not clear to me how I apply this SSL / TLS configurtion to the soap service I am running.

I have a client sending us data MLLP in base64 format. I'm using the EnsLib.HL7.Adapter.TCPInboundAdapter adapter. What setting do I change to accept the base64?

Is there a way to do this? I found the way to store .gz files, but .zip files are different.

Hi community members!

I'd like to know about what source control version is recommended to use with Caché / Ensemble. Can someone help me? If yes, there is some documentation to how to configure?

Thanks,

José Sampaio.

I only recently noticed the presence of a local database named CACHE alongside the more familiar CACHESYS, CACHELIB, CACHETEMP and CACHEAUDIT.

A bit of digging through the documentation archive led me to conclude that the CACHE database arrived in 2010.2, where the release notes say:

Note the lack of an accent on the words I have highlighted.

The above documentation is incorrect when it says "this database is mounted as read-only". In fact it is mounted RW. But the %DB_CACHE security resource that controls access to it only grants R as its public permission.

With help from others here I had developed some code to take a Base64 PDF within a OBX.5 and save it locally to the file structure on the server.

I had to make a change to the code to return me a String so I can pass the Path back into Ensemble to use it in the message. When I made this change I am getting " ERROR #5034: Invalid status code structure ("/ensemble/data/transfer/AncillaryPDF/TMSAUDIO/Apr-11-1/980512729TMSAUDIO1046784936436537800.pdf")"

Here is the code...

Prior to 2017.1, whenever I created a new namespace using Portal on Ensemble or HealthShare it was automatically configured to host productions. This used to irritate me, because sometimes I'm setting up a namespace (for example, to host our Deltanji tool) that doesn't need the extra Ensemble baggage.

Sometimes I observe people scrolling manually down to the bottom of the Console Log document when they want to see the most recent messages. So I want to draw attention to the handy link that does the job for you in a single click:

If you deal with multiple instances of Caché / Ensemble / HealthShare and sometimes have to work at the Terminal command prompt, did you know that you can easily add extra information to that prompt which may help prevent you running a command on the wrong instance?

I created a DTL to do HL7 mapping. The test function in the tools works the DTL perfectly but when used by the rule in my business process, the OBX segments are stripped and the MRN is gone. The assigning authority and ID type are added into the PID but the actual patient MRN is blank (3.1 value).

Here is the source code. 

<transform sourceClass='EnsLib.HL7.Message' targetClass='EnsLib.HL7.Message' sourceDocType='2.3:MDM_T02' targetDocType='2.5:MDM_T02' create='new' language='objectscript' >

<assign value='source.{MSH}' property='target.

Has anybody created a way to change the background color of a cell depending on the value contained in the cell. This is simple when only one background color is required. However, if there is a requirement for several different colors depending on the value of the cell, the out of the box <condition/> approach does not suffice. Thank you for any feedback.

I have an EMR sending double quotes "" as the value. How do I write criteria to find this match in a DTL?
