Globals, Arrays, and Variables Part 2

A thorough understanding of Globals, Arrays, and Variables is foundational for every Caché developer.

Uniqueness of the Caché Global Structure or database

The Caché Database Structure is unique among databases; it was designed and created in the 1960s to be used primarily with HealthCare applications.

Hi ,

  We upgraded the cache 5.02 to cache 16.
  we are using stream property in one class .(i.e.  Property notes As Stream;) but it not support in cache 16.
 how handle this problem?

Thanks, sansa.

Some time ago, I was started to work at a new company even in other country, and more important in a different sphere when I have not been worked before, in HealthCare.

I know %CSP.Daemon is supposed to clean up old CSP sessions (?).  In my management portal, under System/ License Usage, I see 33 "Units" used (and there are 33 licenses  in use), but usernames from old IP address and that are not being  used.  Their active times are often in the millions of seconds.  They are not "on" the system right now.  

At most, only 3 users are on the system right now.

Are these supposed to be cleaned up?  Can I clean them up programmactially, and how would I know if they're not active?

Thanks,

Laura

as described in How to post an article from Word or Google Docs, you can use the Paste from Word button to paste content you have copied from a Word or Google Docs document into a Developer Community post.

this worked well for me pasting from Word 10 documents, and retained most (though not all) of my Word formatting. i did have one problem, however, and wanted to pass on my workaround.

if there are external links in the Word document, they sometimes don’t work when pasted in until you manually add http:// or https://, which can get stripped (don't know if this applies to Google Docs).

What are the difference between $ and $$ symbols using macro.

In a conference call earlier this week, a customer described how they built an iKnow domain with clinical notes and now wanted to filter the contents of that domain based on the patient's diagnosis codes. With such filters, they wanted to explore the corellations between iKnow entities and certain diagnosis codes, first through the Knowledge Portal to get a good sense of the sort of entities and then through more analytical means with the aim of eventually building smart early warning systems.

In an iKnow domain, you can easily define metadata fields that, for every source in your domain, can

What is the syntax for referencing the source config from my process OnRequest method?

I've released a comprehensive, free online training course on the new EWD 3 suite of products that allow the integration of Cache with the burgeoning Node.js world, and allow you to create and run browser-based and mobile applications with all the very latest development technologies from the JavaScript world.

The training course consists of presentation slide decks that you can go through at your own pace and in your own time.

Why we are not using database of join (inner join and outer join) concept. How to we are retrieving the data from different tables in cache. Any Concepts are using in Cache database to retrieve the data.

This short article was motivated by a problem of one of my customers. They use Ensemble to integrate many systems, some of them use just plain files.

So they naturally selected File Outbound Adapter to write into target file. Things were running smoothly for years, until recently, when the volume of data being written to the file reached large size of tens of megabytes. The operation took around half an hour to complete, causing timing problems where subsequent operations within the process had to wait, and third party system was not happy to wait so long.

The customer's code looked somehow

Hi ,

We upgraded cache 5.02 to cache 16.In this version it is having problem with "$$$" macros.

These are the error's eating my time. i tried to figure it out but there is no exact solution .

MPP5610 : Referenced macro not defined: 'CSPSessionTimeout'
MPP5610 : Referenced macro not defined: 'CacheError'

I checked the check list also "These macros will be the only ones displayed by StudioAssist when the sequence, “$$$”, is recognized during program input. The full set of macros and their definition can be displayed via the $SYSTEM.OBJ.ShowMacros method"

there is no definition for

NewBie's Corner Session 25 Globals, Variables, and Arrays Part 1

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

Globals, Arrays, and Variables

A thorough understanding of Globals, Arrays, and Variables is foundational for every Caché developer.

A Global may be:

Scalar (a single element), as in a Global Variable

Example of Global Variables

Set ^PERSON = "DAVID – DATA ABOUT DAVID"

Set ^PERSON2 = "MICHAEL – DATA ABOUT MICHAEL"

Aggregate (many elements), as in a Global Array. An Array combines similar elements together.

Example of an Global Array

Set

Hi All,

      While upgrade cache 5.02 to cache 16.

     $$$CacheError and $$$CacheError not support in cache 16. 
     We need solution for this?

<csp:CLASS super=%CSP.Error>

A question from Benjamin Linden:

We are looking to upgrade the hardware for our server.

Do we need to buy a new Caché license? Or can we keep using the one we have?
 

Dear Colleagues,

Recently I am working on a Cache project should enable the customer, to update our Cache application independently from us. Our idea is a client (preferred .net) application that will copy all the necessary Cache stuff (classes, routines) into a cache database. For this, we are looking for the appropriate technology – in old times this would be a CacheDirect.

Our question: considering up-to-date technologies there seems to be a bootstrap problem: How could one add classes and/or routines to an empty Cache database without using Cache administration tools like the system

If a user simply closes a tab (running a web application), is there any good way to ensure that the license is released AND the login cookie is destroyed?  

I found that if the tab is simply closed without first logging out of the application, then 1) the license hangs around forever, and 2) if the user then opens a tab, he is already logged in.

For #2, I understand that there might be some grace period to allow the user to log in automatically again using the same session Id (where is that documentation again?) but what about destroying the license?  Who/what is supposed to clean that up?

Hello, guys.

Is there a way to get all object properties, parameters and so on and put it inside a string. I know that I can use 

zw obj, but this does not work if I want to put it inside a string.

Hi

I do not really have much information yet about an upcoming mission but i know it is about to seal a flatfile and then send it further. I think  SHA256 HMAC will be used. There is a fixed sealkey to be used each time. Does anyone know if the Ensemble supports this ? I have looked in the documentation but not really found anything .

Regards,

Michael Lundberg

UPDATE: Found a reason in my code why this could be occurring. Still it would be interesting to hear what people come back with.

Consider the following MERGE statement.

 M ^WORKDELETED(DAYNUM,WKS,ACC,$H,%logname)=^WORK(DAYNUM,WKS,ACC)

Produces output

^WORKDELETED(64165,366,16090404088,"64165,34201","user001")="SOME DATA"
^WORKDELETED(64165,366,16090404088,"64165,34201","user001",0,"LOG")="64163*11:05*user001*64163,39919*~"

I have an application developed in Zen mode. How do I "package" and create an application to run on Android. How do I create the apk file?
Thank you

I want to create a simple Json extract from a database in Cache. Suggestions as to classes, method, etc. are most welcome.

Is there any update on when the RSS feed will be fixed to finally include a Title field. This was reported about 5 months ago. Specifically:

The RSS feed for groups (or communities as the link currently says) does not include a title, e.g. for:

https://community.intersystems.com/group/8081/feed

Starts with:

    <title></title>
    <link>https://community.intersystems.com/group/8081</link>
    <description></description>

So there is no title or description of this feed. Also is there a feed for all content posted to this site, so not filtered by tag/group at all?

Hi ,

we need to upgrade the Cache 5.02 to cache 16 in windows server 12. How to upgrade cache 16 in same cube of cache 5.02.

note:we need to upgrade existing cache 5.02 not new instance.

Thanks, sanasa.

I have found this one line command from the Terminal is the quickest way to backup my routines.

In the Namespace the routines reside:

w $SYSTEM.OBJ.Export("MYRTNS*.MAC","C:\Users\Username\Desktop\MYRTNS.BCK-9-2-2016-8AM")

I was recently troubleshooting a problem on a Linux (RHEL) instance of 2016.1 at a site. For policy reasons their sysadmins wanted to update the Caché installation so it used network accounts for its cacheusr and iscagent users and groups instead of the locally-created ones that had been set up during original install of Caché.

To do this they ran various commands including chown

Afterwards non-root users couldn't obtain a terminal session using the csession command. Instead they receive this message:

cache: Permission denied

It turned out that the chown command cleared important setuid and
