Having been inspired with Shared code execution speed question/discussion, I dare to ask another one which is annoying me and my colleagues for several weeks.
We have a routine called Lib that comprises 200 $$-functions of 1500 code lines total. It was noticed that after calling _any_ function of another rather big routine (1900 functions, 32000 lines) the next call of $$someFunction^Lib(x) is getting 10-20% slower than previous call of the same function. This effect doesn't depend on:
Let's suppose two different routines use one and the same chunk of code. From the object-oriented POV, a good decision is to have this chunk of code in a separate class and have both routines call it. However, whenever you call code outside of the routine as opposed to calling code in the same routine, some execution speed is lost. For reports churning through millions of transactions this lost speed might be noticeable. Any advice how to optimize specifically speed?
Just building a simple frontend->JSON->IRIS backend story, and figured that IRIS while importing via %JSON.Adaptor wants JSON fields to match property names, meaning even should match the case. Like:
{ name: "John",
surname: "Doe"}
will have issues while saving the dynamic object to a class Sample.Person with:
I like the Application Error Log functionality a lot. However, it becomes time consuming to inspect it date by date and directory by directory on a multidirectory server. Ideally, I would use an existing error class to write a custom error report by date, selected namespaces, etc. Does such a system class actually exist? Not that I found. The detail level on the screenshot below is enough.
I encountered the following errors while installing the ZPM module on version 2025.1. The ZPM install command failed on the Community Edition of IRIS for Health.
I have a class with a projection that creates some persistent classes (chunks) and a non-persistent "Daemon" class that I want to have running in the background, doing some processing. The daemon needs to look at the "chunk" classes, and I want it to be simple to start the daemon -- I am currently calling the daemon's start method at the end of the CreateProjection method.
I have notified that on several servers the IRISTEMP database is reported as only a few GB in size while on the disk where it's located, the IRIS.DAT file is much bigger (eg: 3GB reported in Portal (including free space) while file on the disk file is 121GB). The last modification date of IRIS.DAT is recent so I'm not looking into a location no more in use.
Is there an explanation for that difference in size ?
How can I create Python pages instead of CSP or Zen pages, not familiar with Python and the only way I know is using embedded Python as methods as attached below?
I seem to remember making this work before, but I'm not having any luck digging up examples.
I've defined some custom properties for a business operation that could definitely benefit from having popup descriptions available in the Production Configuration. I have triple-slash comments before each property that do just that in the source. I thought those provided the text for the popup descriptions when clicking on the property name, but apparently not.
I'm trying to use %Net.WebSocket.Client to collect data from a sever,
and part of that I needed to implement Two classes (SX3.Production.HTTP.AdvCredenials & SX3.Production.HTTP.AdvListener) as below for the purpose of Credentials & EventListener properties,
Is a layer before the internal HTTP of Caché/IRIS, such as a Reverse Proxy or API Gateway, a good option?
Example: I have an API using %CSP.REST, and I am using the internal port for development. But for production and approval, I put a reverse proxy using NGINX. Is this recommended? Is it an alternative?
Is it possible to audit code changes in a namespace?
Ideally what we'd like to be able to do is check which classes were compiled (or deleted) in a time period, eg in last 3 months, and which user made those changes. Even better would be an audit of what those changes were, but that's less important (for us, as we can probably find that information in other ways).
I have an application that is requires an Encoded HL7 message sent over SOAP over HTTPS using SSL/TLS... the Response that is return is also encoded, which I know how to Decode but not sure when I Decode the response how to Extract the HL7 message to send back to the router.
How do I capture the Routing Source System and parse the encoded message back into an HL7 format that would show on the trace viewer?
