This post will show you an approach to size shared memory requirements for database applications running on InterSystems data platforms including global and routine buffers, gmheap, and locksize as well as some performance tips you should consider when configuring servers and when virtualizing Caché applications. As ever when I talk about Caché I mean all the data platform (Ensemble, HealthShare, iKnow and Caché).

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?

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).

I know now there are concepts of file locks and logs for when certain tasks are ran or when a user maybe edits a file

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,

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:

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:

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.

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)

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.

Hello!

Intersystems is a fascinating yet niche marketed.
We are using it, but we struggle to find good developers to join us to work on Caché or Ensemble products.

Who is interested into joining us? the job will be in Geneva, Switzerland!

For more information, please drop me an email to: erika.stegagnini@ch.randstad.com or call me directly +41 58 2015408.

Thanks!

Good day, every process in my software is about to update 3 specific globals in row when the process is called to do some job. I need to guarantee that during updating of those globals with multiple processes there is only one process that is actually working with those globals. Moreover I need my globals unreadable if other process is in critical area.


Example:
