Mirroring provides an admin capability to Stop Mirroring on this member, which causes a non-primary member to temporarily disconnect from the primary, stop dejournaling, etc.  While most system administrators may never need or use this function, some employ it for certain kinds of maintenance or other special cases.

The intent is that the administrator uses the Start Mirroring function when they wish the member to reconnect. However, today mirroring also implicitly restarts (reconnects) if the Caché instance restarts.

Hello!

I have a WebSocket application which spawns new process using JOB command.

Sometimes WebSocket connection can be terminated, and in the meantime I need to hold spawned process alive until it can be associated with the new WebSocket connection. (Do not suggest serializing process state here instead please)

Technically, in Caché WebSocket connection is represented by the class, which executes in its own process. This process is terminated when the connection is lost. In this case the JOBbed process does not terminates (thanks Edward), but it rely on $ZPARENT variable.

On June 7th we'll be releasing two new views of content that will allow you to rapidly see what's new on the site as well as identify content that has gone unanswered. The next step for this (after this release) will be to add in personalization so that you can filter content based on your tag and member "following" preferences.

Hello,

Why I don't see the full content of a XML file inside a Ens.StreamContainer Message?

When  I look into the content I only see:

<?xml version="1.0" ?><!-- type: Ens.StreamContainer  id: 5 -->
<StreamContainer><OriginalFilename>C:\Temp\In\aa.xml</OriginalFilename><Stream></Stream><Type>FC</Type></StreamContainer>

How I can see all the content? There is any setting to modify this behavior?

I am using a EnsLib.File.PassthroughService,

Regards

Hi, Community!

Last weekend we held the Final of InterSystems Contest on Caché, DeepSee and iKnow under the aegis of IT Planet Student Championship in Ekaterinburg. BTW, this year we had more than 1,400 participants in InterSystems Contest.

One of the tasks for the final was to solve T9 Spelling problem  with Caché ObjectScript and use the minimum code. 

Problem description:
The Latin alphabet contains 26 characters and telephones only have ten digits on the keypad. We would like to make it easier to write a message to your friend using a sequence of keypresses to indicate the desired characters.

When I open a Business Process in Studio I am shown a BPL diagram.

 I want to see a class definition directly.

Is there any way to achieve that behaviour in Studio?

I am pleased to announce the field test of Caché and Ensemble 2016.3 -  with many new improvements.

The product team at InterSystems looks forward to your participation in the field test and feedback over the coming months.

Some of the more signification changes in 2016.3 are new RESTful APIs for iKnow and broader APIs for programmatic control of multiple servers (enterprise manager).  As always, there are a host of scalability and performance improvements, including improvements to the core database and SQL.  And hundreds of smaller improvements and corrections.

Hi -

After having seen how Atelier is working, I've decided to start learning/using Atelier for an existing project.

I've installed, and after a bit of poking around, I've managed to get a project that includes my classes, and they compile and such (these were all from an existing export), but I see that NONE of my .csp files came along despite being in the export file.

I'm trying to figure out what the planned strategy is for .

Hi!

Sometimes, especially when I work with Combined Cubes, I need to have all the dates in Date Dimension, not only members with rows in Fact table.

Is there any way to switch it on?

Hello

During some consultant activity I did at a client's I have discovered something very interesting. It seems like the current processing cycle as written in ObjectScript has trouble utilizing an SSD-based storage machine with five-digit IOPS.

Is there any official answer to this question: Does Atelier only support Unicode servers?

Thanks,

Joyce

We have put a new modern and responsive UI design on top of our existing product documentation. It is available in a public beta here: http://docs.intersystems.com/beta/csp/docbook/DocBook.UI.FramePage.cls

Please review the new design and give us your feedback.

Recently I was asked by a customer with this question. In MS SQL Server, there is a function called host_name() that will return the work station name.

Here is how I would do it in Caché :

With default SQL schema name, in my case SQLUser in SQL (which is equivalent as User in Caché class definition), I have a class called User.dummy, I added a classmethod called hostname and expose it as SQL function host_name:

/// 
Class User.Dummy Extends %Persistent [ ClassType = persistent, DdlAllowed, ProcedureBlock, SqlRowIdPrivate, SqlTableName = dummy, StorageStrategy = "" ]
{
Property f1 As %Library.

I have a ZEN page with buttons, text boxes and a tab group. The tab group contains a single tab which I use to display an image(src). When the user, uses the browser zoom capabilities to reduce or enlarge the image, the other controls are reduced or enlarged as well. How can I reduce or enlarge the tab src alone? Thank you for any and all input.

NewBie's Corner Session 6 If and Kill commands

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Click on the Caché Cube in your system tray and select Terminal to try out the commands.

As in other computer programming languages, the If command is the primary decision makes.

If command with numeric operands

Set X=12

If X=12 Set X=13

Write X

13

If command with alphanumeric operands

Set X="ABC"

If X="ABC" Set X="XYZ"

Write X

XYZ

Whenever alphanumeric data is being referenced, quotation marks are required.

Hi all - I'm running a Zen page that inherits from %Zen.Component.page, and I'd like to step through code and debug it.  Is this possible, and how?

I've tried to attach to a process that I think is mine (it has my internal IP address) but is using "Unknown User".  Any ideas on where to start debugging the page  -- this page calls lots of other pages.  I'd thought I'd start at the home page.  

Perhaps I need to navigate to my page that I want to debug, and attach at that point.

Any info on the debugger in this atypical use is appreciated.

Thank  you,

Laura

What would be the easiest or best way to filter the options presented by a filter control?

For example, suppose that I create a query using HoleFoods that uses a named filter to filter the product categories according to some criteria. When I display the query on the dashboard, I would like to provide a filter control that will allow users to further constrain the product categories. However, a simple filter control will display all the product categories available in the cube many of which are irrelevant to the current query.

Thanks for your help!

This is more of an eclipse thing, but I couldn't really find an answer when I searched.  I created a new workspace, but I had updated my keyboard shortcuts in the first workspace and now I'm trying to import the changes.  I successfully exported them as .csv, but I cannot find a way to import the changes into the new workspace.

Any help would be appreciated.

I have a homeTemplate and ExamesTemplate page. When I'm in ExamesTemplate and make a resfresh (F5 browser), the page back to the HomeTemplate. I need the page ExamesTemplate not return HomeTemplate.

I'm using ZenMojo with Bootstrap

Can someone help me?

Thanks.

Hi,

I am working on a DataGrid based upon ZenTest.Datagrid.cls

I want to save data after changes on a row.

The existing samples do not explain how to save changes on data in a grid.

I have tried something like zen(‘json’).save

Does anybody has some sample code?

I have a production system that has a large dataset of about 2 million rows. I need to create an index on a property but don't want it available to queries until the index is fully populated. Is there a way I can create the indexed, fire off the build, then "activate" the index so queries can use it.

The problem I face is the minute I create the index queries start returning zero rows because it starts using the index. As I start building it starts returning qualifying rows for those it has indexed but misses those not yet processed.

I am just trying to make a quick hand off HTTP production. I have the class built and compiled onto the server and the production is running as a service. When the production is called (by an inbound job) I can see that the HTTP.InboundAdapter is being used successfully and the stack continues all the up to ProcessInput where OnProcessInput is called in Ens.BusinessService. Instead of using the class that I wrote which has both extended Ens.BusinessService and implemented my own overriden OnProcessInput method, it calls the OnProcessInput within the Ens.

Hi,

Assume an architecture where an ECP Database Server is connected to by one or more ECP Application Servers inside a firewall.The application server hosts the web application that web users connect to.

The Web servers are outside the firewall, and, (using the CSP gateway/server mechanism) issue requests over the SuperServer port and into the application server.

I know that the traffic between the Web Server and the ECP application server can be encrypted using HTTPS, and access to the CSPServer on the Application server is username/password secured.

This article is about DeepSee Listing Groups, a new DeepSee feature that was introduced in release 2015.2.

DeepSee Listings have always been a part of DeepSee.  DeepSee Listing Groups provide increased flexibility by allowing you to create new DeepSee Listings without modifying the cube definition.

Hello,

is there any API available that would return an MDX query string for a given saved pivot name? I could not find anything except for pivots with manual MDX. But that's not my case, I need to get MDX for any pivot.

TIA!

Hi ,

In HSBUS we have out of box operation HS.IHE.XDSb.Repository.Operations to route CCD's from HSBUS to Edge gateway.

Earlier it was working fine, but for maintenance we have to rest the DEV environment, Now its throwing below error. I have verified all registry configuration and the CCD feed is also same, nothing is changed except reset. Can someone help me, where to look for this problem or what I am missing here.

I have a tool I absolutely love for HL7 v2 analysis and manipulation. It's called 7edit.  I'm wondering if there is anything similar for HL7v3/CDA/CCD.  I know it is considerably more complex, but I still have hope.

So far the best resource I've found is http://www.cdapro.com/.  I'd love to hear anyone else's tips for tools or resources.
