Restore Database issue

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.

Supporting FIPS 140-2

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.

VSI OpenVMS

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.

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

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.

Authentication with REST

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?

Diagnosing the cause of <PROTECT> errors

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):

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...

At the end of our last lesson, we ended with our page displaying a nice (but garish) Angular Material Toolbar, and our Widget data displaying in a list of Material cards. Our page feels a bit static, and we already know that the large number of Widgets that we will be dealing with will not be especially usable on a static list. What can we do to help?

Hi,

We have a application developed in CSP and JS. Is there any way to make this application available in multiple language like Spanish etc.

We are ready to re-write the code in Zen also if it supports that feature.

Could any one of you please assist/advice a Solution to reach the required goal using Cache technologies, it will be a great help if someone has any sample code for the same.

Thanks

Paras

Atelier Users:

Has anyone found an Eclipse plug-in that provides the capability to connect to a Caché server and give the user a way to write SQL queries using the tables from that server? I'm picturing something like a "WinSQL"-client built as an Eclipse plugin.

I've found and tried the following, but I couldn't get it to connect to my local Caché instance.
