This post will guide you through the process of sizing shared memory requirements for database applications running on InterSystems data platforms. It will cover key aspects such as global and routine buffers, gmheap, and locksize, providing you with a comprehensive understanding. Additionally, it will offer performance tips for configuring servers and virtualizing IRIS applications. Please note that when I refer to IRIS, I include all the data platforms (Ensemble, HealthShare, iKnow, Caché, and IRIS).

Ok, I am trying to do my homework here but seem to be sinking.

I installed Atelier from the link    atelier-1.0.0AT.262.0-win_x64.exe  from at Atelier home page

(https://download.intersystems.com/download/atelier.csp)

Then I install Java from https://java.com/en/download/win10.jsp

I found the Atelier App but it gives this whole page of stuff and at the top it says I have an exit status code of 13.

I have looked through a number of post on Atelier and now am lost.

Any direction please?

Hello everybody,

We have a piece of Caché software which calls an external utility using $zf(-1,command). It works fine under Linux, but under Windows an external process occasionally hangs (due to some internal problems out of the scope here) and need to be killed programmatically. Having PID, it's easy to kill a process. If a Caché process is called with JOB command, the caller can easily get its PID from $zchild, but alas $zf(-1) does not seem to return the similar info. Is it possible to get it somehow?

This is the first article of a series diving into visualization tools and analysis of time series data. Obviously we are most interested in looking at performance related data we can gather from the Caché family of products. However, as we'll see down the road, we are absolutely not limited to that. For now we are exploring python and the libraries/tools available within that ecosystem.

The series is closely tying into Murray's excellent series about Caché performance and monitoring (see here) and more specifically this article.

I was wondering if there was a way to if the user is using Studio and changes a file to get the users name and have a function run when the file is changed. 

Ive got this working for .int files but not for .csp or .js or .css or any other kinds of files. 

When we edit code we are logged in to the Cache backend’s server through Studio by using an iPaddress (which is on our network).

Good day, this is just question from  beginner, but I often use Atelier export to export my file as XML for Caché Unit Testing and I didn't find solution for my problem.

And every time I want to export I had to retype export settings again and again. On the other hand, studio always remembered my last exported data paths. Is there some option in settings to set Atelier to remember export settings please? Or there is some other way please, any ideas? (I use Atelier xml exports sometimes 30 times a hour)

Project related quality assurance efforts have revealed a number of concerns for the current release of 2017.1.0 and 2017.1.1 on all OpenVMS platforms. In certain situations, the impact can be severe. InterSystems will address these issues with the upcoming 2017.1.2 release, and in the meantime, will remove all 2017.1.x kits for OpenVMS from our Download Servers.

If you have immediate needs correcting existing deployments of this version, please contact the InterSystems WRC (support@intersystems.com).

Hi, Community!

Hi, Community!

I'm pleased to announce that we introduced the second release on DC in August.

Hi Community! 

This week we have three videos. Check all new videos on InterSystems Developers YouTube Channel:

1. Using Atelier and Git, Moving your code to a new Repository

Hello all,

In my ZEN login page, I found a way  to bypass the submit button and force a user to click on the Sign In button, thus forcing the code to call my OnSubmit(), like this:

<!--ondefault="return true;"--><!-- this removes the ability to use "return" to login - forces button click to login -->

<loginForm id="loginForm"   ondefault="return true;">

<text name="CacheUserName" />
<password name="CachePassword" />
<!-- the submit button is special, and submits automatically without checking first -->
<!

how do we do estimation in Intersystems ? what is the unit of  work that we refer for intersystems ? let's say for example if we to add 200 fields how many business classes ( Business service, Business process, Business operations) that we must change  ?

Any thumb rule ? Please let know

I know there are numerous Java libraries available to scan a PDF meta data, but is there a way to scan a PDF using native cache object script? We are looking to take a PDF from an external vendor, scan for meta data, create the HL7 message, and embed the PDF within the HL7 message.

Thanks

We have some productions in Ensemble that uses DotNetGateway to use dll created with .Net. The DotNetGateway is configured with a port number, and then the operation uses that port.

But sometimes, suddenly Ensemble answers that the port is already in use, but it is only used by the DotNetGateway. And the only way to resolve this and make the port available again, is to restart the full server. We have tried to restart Ensemble, to kill the process that may be using the port and nothing.

After Microsoft updates my Cache Cube has stopped working.  I checked my cconsole.log and corrected my journaling errors.  However, I still receive Native Code 450 errors but now I am receiving Network Errors.  However, now there do not appear to be any errors logged in my cconsole.log.

I have reinstalled Cache Cube multiple times without success.  Can anyone please provide some assistance?

Thank you,

Hi!

When trying to receive xml response 

set sc = ##class(%XML.TextReader).ParseString(str,.reader)

I'm getting error bellow: 

Invalid character (Unicode: 0x1A) while processing Anonymous Stream at line 2 offset 281

How I can ignore this error? Thank you.

In $system.SQL.Shell(), it would also report the number of global references for a given query.

Is it possible that I could also get this statistics from the %SQL.Statement interface when I launch a dynamic sql?

Thanks.

Quite a few enhancements have appeared over recent months in QEWD for easing and simplifying the creation of REST-based services.  It's now even more slick and powerful,  allowing you to very quickly create very high-performance, highly-scalable REST (and Web) services that make use of Cache.

I've therefore updated the training presentation deck (Part 31 on developing REST Services with QEWD).  It describes all the new features with worked examples.  See:

https://www.slideshare.net/robtweed/ewd-3-training-course-part-31-ewdxp…

Here's one way to determine if a class is mapped (i.e. it is in a package whose definitions come from a database other than the default code database for the current namespace):

SAMPLES>w ##class(%Library.RoutineMgr).IsMapped("Cinema.Film.cls")
0
SAMPLES>w ##class(%Library.RoutineMgr).IsMapped("%iKnow.Objects.Source.cls")
1
SAMPLES>

If you pass a by-ref second argument to IsMapped you can also discover what database the class definition is stored in:

SAMPLES>w ##class(%Library.RoutineMgr).IsMapped("%iKnow.Objects.Source.cls",.

I want to retrieve all the names of classes which are %Persistent in a namespace by COS.

Any suggestion, Thanks.

So I have an ensemble soap client which I use to send a message. The target web service is, however, giving a soapfault stating that my message misses the "SoapAction http header".

When I copy paste the message from my Cache Soap Log and fire it from Soap UI I get a proper response from the target web service. This suggests that my intersystems installation is somehow not including or losing some http headers. 

I am running Ensemble 2016.2 SUSE on an ubuntu machine.

Here is the InterSystems message with the http headers from Soap UI:

POST https://test.salesforce.com/services/Soap/c/40.

Hyper-Converged Infrastructure (HCI) solutions have been gaining traction for the last few years with the number of deployments now increasing rapidly. IT decision makers are considering HCI when scoping new deployments or hardware refreshes especially for applications already virtualised on VMware. Reasons for choosing HCI include; dealing with a single vendor, validated interoperability between all hardware and software components, high performance especially IO, simple scalability by addition of hosts, simplified deployment and simplified management.

Has anybody defined their own Cache ObjectScript (COS) commands and symbols? Is it even possible? For a list of currently used commands and symbols please use the following link.

TablePane1 is populated when a %ZEN.Component.button on a form is clicked from a JavaScript onclick method.

 onselectrow="zenPage.onSelectRow()"

This JavaScript method gets the RowID and feeds it into ClassMethod GetAuditLogs(ByRef pRowId) [ ZenMethod ] to get the audit events for that record.

ClientMethod onSelectRow() [ Language = javascript ]
{
 	var table=zenPage.getComponentById('table1');
	var dataRow=table.

I'd like to access and view the soap log. Apparently there is a global for that (^ISCSOAP) (http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY…), but insofar I have been unsuccessful finding the exact cache command for viewing the soap log or changing it so that it logs both incoming and outgoing traffic. Can anyone enlighten me?

I.e. I am trying stuff like:

set ^ISCSOAP("Log") = io   

write ^ISCSOAP("Log)

but those don't work.

I use %SQL.Statement. The original column names are not contained in the metadata.

Sample query:

SELECT
 column1->name as name,
 column2 age
FROM sample.table

How to get:

•  column1->name
•  column2 

I have a few productions that my developers named "TEST" and would ideally would like them to have more relevant names. Is there a way to rename a production? I tried exporting and deploying the production under a new name and it worked, but my new production is empty. Also I'd like to delete a production that is in a suspended state. When I attempt to delete the suspended production, I get errors that the production isn't stopped, so can't be deleted. I can't start it to clear the suspended status, either. I get the following error:

14:26:18.126:Ens.Director: Production 'CHSLI.TEST' starting.

Hi

I've got a Service that get ACK Messages originated by another system. 

I want to get the details of a Message when the ACK is CE (Failed Message).

I don't know whether this is the best approach but, at the moment, I have a DTL and I would like to search the Cache Database for a Message with the Control ID on the ACK in the MSA segment.

Any help with this would be great.

Tks.

Please excuse my ignorance. I am trying to identify what areas would be best to review in the System Dashboard (for Cache 2010.2) for performance issues with the database. It seems to be running slower than usual, but I am trying to find out the best way to go about identifying what the issue is.

The following are captures from the System Dashboard.

As always, thanks a lot for your help.
