Hello developer community developers!

Thanks for all of features you create.

I encourage the one simple issue again and again when posting articles. Would be happy if it get fixed.

When publishing an article draft, the date of the post should be the date of publishing, but not the date when the draft was created.

When the post is created and saved as a draft it usually takes some time to actually finish the post and publish it.In my case, it took 3 days.

Hi everyone!

     I am helping a partner to develop a new application and one of the things we are facing is that this WEB application will be used on different time zones.

     My first recommendation is that all timestamps should be drawn from $ZTimeStamp instead of $Horolog. That would allow the system to be draw the correct sequence of events even when they are generated on different timezones. 

     On the other hand, it is sometimes useful to know what was the local timezone at the moment the event was generated to compare to events generated on other systems or to correlate to people's

Hi!

I am trying to create a %Installer script and I noticed from our documentation that %Installer's <CSPAuthentication> will only accept:

<CSPApplication>
Optional; within <Namespace>. Defines one or more CSP applications; the supported authentication flags are 4 (Kerberos), 32 (Password), and 64 (Unauthenticated).

 

Is "Delegated" authentication supported? What is it's code?

Kind regards,

Amir Samary

NewBie's Corner Session 4 The Plus Sign and Concatenation Operators

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.

Plus Sign (+) operator

Typically, the Plus sign (+) adds two numbers together. This is true in COS (Caché ObjectScript), but COS uses it in other ways as well.

Set the variable X to a value of +12

Set X=+12
Write X
12

Set the variable X to the value of +"ABC"

Set X=+"ABC"
Write X
0

Here, the Set command sets the variable X to +"ABC".

Hi everyone!

     I am trying to choose the best collation for a new application that will be running on a spanish locale (Chile).

     I can see there are database collations for Spanish1, Spanish2, Spanish4 and Spanish5. What is the difference between them? I can't find anything on our documentation. Should I simply choose the latest (Spanish5)?

Kind regards,

Question Steve Pisani · May 19, 2016

Hi -

Let's say I want to override the HTML that is generated by provided ZEN Mojo Helper Plugins I use the onloadHandler method of my document page, retrieving elements, and modifying them using jQuery syntax.

For example, I'm using bootstrap, and, I want  the <button> element automatically generated with the use of the $navbar layout object, to collapse/expand a different <DIV> on my page, to the default one it produces. 

Is this the correct spot and approach to use ? 

thanks

Good morning, I am using a tableNavigatorBar on a tablepane. I want to execute the onselectrow method of the tablepane each time the tableNavigatorBar is used to proceed to a tablepane record. Has anyone connected these two component in this way before? Thank you for any hints, input and/or comments.

Question Francis Galiegue · May 20, 2016

Hello!

I am trying to install Caché 2016 on a Debian Jessie machine; so I downloaded the latest release from WRC, OS RHEL x86_64, in tarball format.

I untarred it, then launched cinstall; unfortunately a library was missing. I then elected to kill all the processes (which wasn't easy), remove the two users created, and start again.

Unfortunately, for some reason, when I relaunch the install again, the install process still detects the old instance which I installed previously... And I cannot find where this information came from (I removed the install directory by hand entirely).

Where is this

Question Mark Bolinsky · May 19, 2016

Consider a design where there could be three or four or more servers and there is a need to have these eventually consistent between them all (and not considering database mirroring here).  

The current Caché documentation here demonstrates this well using object synchronization between two servers, however it doesn't indicate whether more than two servers can participate to create a "mesh type" deployment.  Below is a diagram of what I'm curious to know is possible to implement with Object Synchronization.

Hi All, 

I am providing support to an AP about using document criteria on Multiple Templates (Explicit Dispatch).

I am trying to set the  criteria value from:

view.setDocumentKey('initial-search',{patirntId:tPatId});

 However it is not possible to get the criteria value on %GetJSONContent through pCriteria parameter object.

How can I do this with Multiple Templates on bootstrap plugin?

Thanks.

NewBie's Corner Session 2 Variables Set and Write commands

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

Session 2 – Click on the Caché Cube in your system tray and select Terminal to try out the commands.

Variables

Like other computer programming languages, Caché uses Variables and the values they represent to control programming. Variables are elements that represent data values. Manipulating and interrogating variables is at the root of programming.

  • Variable names are case-sensitive
  • Variable names should be no longer than 31 characters
  • Variable names must be

Question Jon Jensen · Apr 27, 2016

Looking at the navigation, should we consider moving the Logout function under the My Account button?  It is kind of oldschool to see the logout functionality as  a stand alone menu item.  

Maybe the My Account button should have "Account Settings" and "Logout" as the drop menu items?

Thoughts?

Hi all,

I have a dashboard which shows the growth of the months compared with the month from the last year.

The way I found to develop that, it was with a kpi. So, I overrode the %OnLoadKPI method with two mdx:

SELECT NON EMPTY [DataD].[H1].[MothYear].Members ON ROWS, [Measures].[CountVisits] ON COLUMNS FROM SubjectAtendimento %FILTER [DataD].[H1].[Year].&[2016]

SELECT NON EMPTY [DataD].[H1].[MonthYear].Members ON ROWS, [Measures].[CountVisits] ON COLUMNS FROM SubjectAtendimento %FILTER [DataD].[H1].[Year].&[2015]

And then, I set the %..data variable with the percent growth of the months for each

Hello, our customer, large industrial company, is considering modernizing their old CSP application so it can run on multiple client device types, using responsive design.

They have a lot of experience with CSP and some ZEN.

They are new to REST and have some limited knowledge of javascript - perhaps not enough to the extent used by client framework.

Does anyone have a framework or a set of templates that you would be willing to share?

Thank you!

I have an sql that is refusing to play fairly.

Hello,

I'm trying to connect to a Caché server from Atelier; the Caché server is 2015.x.

The address and port I'm trying to connect to is the SQL gateway server; and I get, each time, an "unexpected end of file from server".

Note that unfortunately, for the moment, I connect as _system... And the Caché install has the default privileges.

What am I doing wrong?

Question Scott Beeson · May 13, 2016

This is a bit weird.  I'm trying to use `DATEDIFF()` to calculate the time since the last message on an interface.  For some reason, when no messages are received, the number steadily decreases.  This is the opposite of what should happen.  Here is my current query and a few sequential result sets:

SELECT getDate() as now, max(TimeCreated) as latest, DATEDIFF (s,getdate(), max(TimeCreated)) as difference
FROM EnsLib_HL7.Message

 

now                  latest               difference

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Feel free to improve it as needed.

Question Mikhail Khomenko · May 12, 2016

Good day, Cache developers and users!

At first, sorry for my bad English -)  I have a little question.

As I know, we can add database to mirror only on Primary Failover Node, using SMP or ^MIRROR.And the usual procedure after that is to copy mirrored database to Backup Failover Node and restore it there (by Backup restore or by Activate-Synchronize procedure).This all works fine.But what if I first have copied the database from Primary to Backup and only than added the database to mirror on Primary Failover Node?(human forgetfulness).

Question Chip Gore · May 10, 2016

Hi -

I'm trying to figure out what is the best (or at least pros & cons) on how to manage login accounts in a multi-tenant SaaS web based application context.

Assume that a company is designing a collections of web based applications that they will be selling as "services" to their clients, and that these clients will each have their own "users" and "customers" that will be logging into these services.

In setting up these login accounts for the "users/customers" of the "clients" of the "company", does setting up a unique domain/user-pool context for each "client" make the most sense?

Often when debugging COS code you get an error message such as '<UNDEFINED>test^routine *test' so the first thing you want to do is to take a look at this code and see what it is doing. From the command line you can:

ZLOAD routine ZPRINT test

Which means splitting the $zerror information into the routine name and the line and adding the zload/zprint commands. Also you often want to view the lines above the one where the error happened as this gives you some context of how you got to this line, using ZPRINT you could 'ZPRINT +1:test' but that may display hundreds of lines.

Since 2013.1 you can
