As we've all heard 2016.2 draws near and brings the removal of system methods with it.

There are two ways to make the code compatible with 2016.2:

• Replace system methods with new methods
• Replace system methods with macros

How to run cache programs(studio) from the command prompt?

Say you have a global in one database that you instead want to map from a different database. If you just create a global mapping to the new database, the existing global will become inaccessible because it still lives on the old database. The documentation notes this problem here but doesn't give details on how to fix it.

When you create the global mapping you need to explicitly move the existing global to the new database. This is possible using the merge command along with extended global reference. The environment syntax lets you reference a global in a specific namespace, directory, or

Hi,

I am wondering if there is a way I can change the GUID of an instance. The use case is that I am restoring from a backup on an alternate host and start the instance there. However, the restored instance ends up with same GUID as that of source. Is there a way I can tell this newly restored instance to use a different GUID?

Thanks,

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.

 How to create an instance for the production class?

I wanted to run the cache programming from the windows command line promt and also with linux commands. Please let me know the procedure. 

Hi Everybody,

I'm trying to restore database to a 2016.2.2.853 caché version but i've some problems ...

Into my backup file, i've 6 namespaces. After use the Do ^DBREST and configure all namespace into the portal, I can only reach 2 of 6.

when I write zn "blabla" into the terminal, i've got this error message :

ZN "blabla"
^
<DIRECTORY> *r:\data\blabla

Of course, Database and namespace are correctly define.

I've try this on a previous version of caché (2015.2.2.811) and it's working fine.
So, do you already got this kind of issue with your caché server ?

Tanks a lot for your help!

With the recent release of Caché and Ensemble 2017.1, InterSystems customers can now create configurations where the data-at-rest cryptographic library used is compliant with FIPS 140-2.

Caché and Ensemble now provides you with the option to enable FIPS mode on RedHat 6.6, 7.1 on x86-64. This means is, that InterSystems products will no longer use the supplied crypto libraries that come with the kit, but will use the FIPS validated libraries provided by the Operating Systems vendor.

To configure your system, RedHat must operating in FIPS mode.

The last version of Caché, Ensemble released for VSI OpenVMS is 2017.1. Unlike HP OpenVMS (Alpha and Itanium), VSI OpenVMS on Itanium continues to be supported. This means that critical corrections or changes required to support customer’s hardware purchases will all be based on 2017.1 or earlier versions.

I've been creating some posts with embedded images, and some of the images seem to stop resolving after a period of time.  I've resaved them, and that has helped temporarily, but I just checked and one of the images is now not resolving again.  Is there a limit to the number of images on a post, or should I be using a specific filename pattern?

THanks

Hi ,

We are trying to import file using %installer . But we are getting error.

CODE:

Include %occInclude Class User.InsClass { // You can see generated method in zsetup+1^App.Installer.1 XData Install [ XMLNamespace = INSTALLER ] { Flags="ck" IgnoreErrors="0"/> } // Entry point method, you need to call // At class compile time it generate Caché ObjectScript code from the manifest // After that you can run this installer from a terminal: // Set pVars("Namespace")="NewNamespace" // Set pVars("SourceDir")="C:\temp\distr\" // Do ##class(User.InsClass).setup(.pVars) ClassMethod

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.

I heed to his a callback method after all REST call. I have already found a method to call before REST call, but after eludes me. Here's the code:

/// This method Gets called prior to dispatch of the request./// that you want to be executed for EVERY request./// request will NOT be dispatched according to the UrlMap.

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?

Hello all,

When I call a WSDL in php, look this code :

// Standard SOAP header for username/password

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).

We finished our last lesson with our Widgets Direct page iterating over a list of widgets, displaying an ID and a Name value. While we have been able to achieve this with only a small amount of coding, the page itself is not the most visually appealing place to be. The AngularJS framework is providing a powerful Model-View-Controller framework for our structure and logic, but it does not implement anything that will provide a nice UI experience. For that we need to implement a UI toolkit.

Has anyone created Delegated Authentication using the Windows Certificate Store? Thank you for any feedback.

We are building a bunch of rest based services using Ens 2016.2 to serve our browser based application (Angular 4).

Two questions:

1. The initial authentication seems only work if credentials are placed in the url parameters.  Trying to use the Authorization header instead, the client code immediately complains about Access-Control-Allow-Origin. How can I resolve this?

2. After initial authentication, what is the proper way to send subsequent rest calls without having to include credential every time?

I have Parameter UseSession As Integer = 1 in my service class, but what else do I need to do?

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.

when the "/apps/docmatic/%CSP.SysConnection.cls" gets hit. If some page hit the above (%CSP.SysConnection) it consume license or not?

WebSockets look to be supported reasonably well in Cache. I have yet to use them in production so I am wondering how well it has worked for other developers.

In particular what happens when the browser does not support WebSockets, or when a firewall blocks the connection.

Have you had to write your own long polling fall-back?

I've read the documentation and found this interesting article...

but no mention of long polling fall-backs that I can see.

Having tinkered around with sockjs and socket.io (with node) there is a

Hello everyone,

Currently we have 2 Windows servers in a clustered environment.  Is there a setting in HealthShare for a TCP/IP Operation to use the virtual IP address when initiating the connection, rather than the host IP address?  

Thanks in advance!

I am using a %Stream.FileCharacter object  and LinkToFile API to write to a file on a folder. The file is written line by line . Something like  below:-

Set tStream =   ##class(%Stream.FileCharacter).%New()

Set tStatus =tStream.LinkToFile("MyFileName")

For i=1:1:X  { Set result = ..process(i) Do tSream.WriteLine(result) }

 An external process then picks up the file at a designated time.Sometimes the process to create this file takes longer than expected and the result is that the external process picks up an incomplete file !!

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