The release of IBM POWER 8 processors with AIX 7.1 introduced up to 8 SMT threads per processor core (logical or physical). Which SMT level (1, 2, 4, or 8) to use can be confusing and varies based on multiple factors. This article is meant to help with a starting point for your specific application.
Firstly, if running on a version of 2014.x or older, it is advised to use SMT 4 or lower. SMT 8 with those older versions of Cache' has shown a decline in performance and scaling in benchmarking applications.
I'm using $ZUTIL(49) to get information of the databases I want to add to a mirror. This information is passed to ##class(SYS.Mirror).CatchupDB(plstPathDatabases) in order to Catchup all databases addes to a Mirror.
We are creating a package (written in Caché Object Script) that will provide access to an external DB (MySQL). Because applications that use our package will be run from machines with various, potentially unexpected, operating systems, we’d like to establish a connection to the external DB without using DSNs (we’ve heard that setting up DSNs on certain non-Windows machines can be cumbersome and problematic).
I'm getting the above error. My zen page calls other javascript methods and other server methods just fine. But when I call my method, I get the error. Yes, I've tried making it look exactly like the methods that work. But for some reason, it doesn't seem to know that DoLogout is a zen method.
Anyone ever get this error?
THanks

for example
ClientMethod logout() [ Language = javascript ] { zenPage.DoLogout(); }
Studio's "Package Information" dialog, accessed from the context menu of a package on the Namespace tab of the Workspace pane, includes a field titled "Routine Prefix"
I need to get a sort order stored in my database with mutiple decimal places, but I want the string stored and retrieved EXACTLY as I enter it. so if someone enters 700.3000 I don't want cache to treat it as a decimal and strip the trailing zeros storing it as 700.3
once it comes back, I want the sorting to sort AS STRINGS, again, none of that stripping training/leading zeros.
this ay, I can create local arrays in exactly the order they think? they created them
There are many storage technologies available today from various vendors. The storage technology and configuration best for your application depends on the application access patterns and workloads.
The attached document discusses the various design considerations and recommendations for various technologies. This guide is to help you during discussions with your storage vendor to determine the appropriate storage technologies and products that will work best to meet the performance goals for your applications.
I have a set of file names (e.g. file.cls, file2.mac and so on) and I need to check whether these files are mapped in %ALL or current namespace.
I found that if I open Globals in the current namespace I can see mapped packages. And If I open this global I see all files that are to this namespace and %SYS. The problem is these files are enumerated in a json object(apparently)
Several years ago, long before Developer Community Portal was launched, I published a series of Caché tricks at one of Czech web sites. In this article, I’m posting translated version of one of them.
Capturing output of someone else’s methods or routines
Suppose you, or someone else created a useful method or routine, that was producing some computation that you’d like to benefit from, but the routine was writing output to process principal device.
You would like to use the data, but you need it not written to a device, but assigned to a variable. And, for any reason, you can’t modify the code. What can you do?
Let's say that we wish to store the documents sent to us via all of our Customers, and that the documents could be in PDF, spreadsheet, RTF, plain text, Comma-Separated-Values and XML.
It would be hoped that %Stream.Object would be a good choice of property to hold these documents, especially as you would expect %Stream.Object to morph between BINARY (for PDF, spreadsheet, RTF) or CHARACTER (for plain text, CSV, XML) depending on which type of stream was being persisted.
If I set %session.Preserve=1 in OnPreWebMethod and I set a variable in my service method, why don't I see the variable in the CSP session processes' variables after I call the method?
This article created as side effect of preparations to the longer set of articles about simple, but still handy MapReduce implementation in Caché. I was looking for relatively easy way to pass arguments to (potentially) multiple targets via remote calling facilities. And after several attempts I have realized that we do have very powerful mechanism in the Caché ObjectScript which might be of particular help here – dynamic dispatch for methods and properties.
I am new to Cache and I am trying to convert a JSON string (msgdata) that contains a JSON payload to an object to be saved into a Driver. Entity table. I am running into 2 issues and would appreciate any help:
1) It seems that when the 1st element of a list within the payload (Choices) is an empty string, after I call %ConvertJSONToObject, the obj.%data("payload").Choices contains just 1 empty element, removing the next 3 valid values (10,20,30). The same does not happen if I change the input to [10,20,"",30], in this case it works correctly.
I want to add a class to my project. This class is in UDL format.
I know that there is a method: ##class(%Compiler.UDL.TextServices).SetTextFromStream. The problem is that to use this method I need to know the name of the class (including all packages) in advance. But, a class can have any name(I mean C:/source/AAA/BBB/CCC.cls, but the real name is Sample.Human.cls).
For now I found only one way to get to know the name of a class - just parse the class code and search for a word which is followed by "Class" word. Is there any better way to do that?
How to get XML subtree from XPATH.DOMResult object as Stream or CacheString.
Here is my classmethod. My system receives XML message which has nested structures. The requirement is to send one message at a time to the destination. I have created the XPATH document and used EvaluateExpression method and which returns XML.XPATH.Result of type DOM. I am able to read the dom and get value of the element and its text. But I am looking to send back the subtree.
I want to query the cache database for messages where a specific HL7 segment equals a specific value. Does Cache have a pipe to XML or hl7 segment query function?
I have two pages and I am using the push and pop to go and back navigation. When I click the button forward and back in the browser, I can't navigate more between pages.
I don't know if this is the proper section to post this kind of issues, but in the learning tracks for Zen I'm not able to play the second video (Caché Demo - Part 5 - Building a Rich Web Interface with InterSystems Zen) , the player show the following error message:
