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).

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

PDFs and Reading them

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

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:

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:

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)

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:
