Hi, all!
As I know, InterSystems recommends the use of Huge Pages. And if count of Huge Pages is enough, we'll see (in cconsole.log) something like this during Cache startup:

But if count of Huge Pages is not enough for location of all Globals and Routines caches, Cache won't use Huge Pages.

The question is: does it exist any metrics (API) in Cache (not in OS), that can show us if Cache uses (or not) Huge Pages currently?
Thanks!

I'm referring to the document Using Cache with JDBC. Using this example, it sets the URL of the object ds of class CacheDataSource.

ds.setURL("jdbc:Cache://127.0.0.1:1972/SAMPLES");
My question is would you just copy and paste the URL from the login page to the string? I tried doing that and it returns an error saying "Invalid log file xyz"

Any help will be greatly appreciated! Thank you

I want to understand how this message is build:

[SYSTEM MONITOR] CPUusage Alert: CPUusage = 99, 99, 99 (Max value is 85).

Caché keep a log of cpu usage (99,99,99) and how is the frequency of check of this?

how can i chance the max value? is that possible?

Best,

Hi, the 2017 filed test key has expired. When can we get the new one?

Hello,
I want to process more requests per second in Ensemble 2015 (soap service). My problem is in a business process that makes a great transformation. I thought that I can put its group size to 4 (the current value is 1), or put 4 business processes and apply, for example, the round-robin algorithm.
Which alternative is better?

I have many items in business services.

one of my particular business service is frequently asking restart.

Is there any code to update particular business services out of all services?

Thanks in advance...

I have a running Cache DB system that the password for DBA isn't given the default password. How should one go to reset the password without having the credentials for DBA?

Connected Data London Conference

TRIADB is an emerging unique and valuable technology in NoSQL database modelling and BI analytics. The following video is from a presentation and demonstration of TRIADB prototype implemented on top of Intersystems Cache database and driven with a CLI in Python (Jupyter-Pandas). In fact this is the second time in the past year that a prototype based on this technology is implemented and demonstrated. The first one was built on top of OrientDB multi-model database and driven by a Mathematica notebook.

Hi,

Can I get "Window Size" from terminal? By command line.

Terminal > Edit > Window Size

I already tried to use 'do CURRENT^%IS', but without success. It does not return the change, for example, when the column is 132.

Is there any routine or method for this?

Newbie question. So bear with me please.

We have a requirement to extract or build a file off of our local db to feed to HealthShare.

The requirement is for us to create the extract and send it to HealthShare the SDA format.

My initial thought is why would you do that when the SDA is native to HS.  We could create a file in any format csv,tab etc let HS consume it, convert it to HL7 2.5.1 and then let HS do the work with the SDA.

However, the current direction is for us to query, get the data and map it to an xml file built off of the SDA.

Has anyone taken this approach?

Thanks in advance,

Hi, Community!  

Please find a new session recording from Global Summit 2017:

Disaster Recovery for Federated Systems

A practical guide to using the tools PERFMON and MONLBL.

Introduction

When investigating performance problems, I often use the utilities ^PERFMON and ^%SYS.MONLBL to identify exactly where in the application pieces of code are taking a long time to execute. In this short paper I will describe an approach that first uses ^PERFMON to identify the busiest routines and then uses ^%SYS.MONLBL to analyze those routines in detail to show which lines are the most expensive.

The details of ^PERFMON and ^%SYS.

Hi everyone

I'm new in Cache development language and I'm starting setting up Unit Tests.

How do you check with an Assert whether a certain variable is null or undefined?

The following assert throws an error on the "null": do $$$AssertEquals(myObj, null, "myObj is null")

Thanks a lot for your help and best regards

select * from A left join B on A.x = B.x inner join C on B.y = C.y

does Cache SQL treat the join path: LEFT_JOIN(A,INNER_JOIN(B.C)) also a valid candidate path?

Thanks.

What is difference between using a command $classmethod rather than just invoking them straight away?

For example if i need to call a class and its method i can just use like

do ##class(circle).radius()

rather than using

do $classmethod("circle",radius)

(I suppose both of them doing the same function i am not aware of it)

Please help me understand what is different and is there any specific usage.

Correct me if i have made mistake.

I have made a complete copy of our test namespace into a secondary test namespace.  Thereby we can test with our current EHR version and our soon to be deployed EHR version simultaneously.    However, we have a number of saved searches within the Message Viewer that we would like to have available within our secondary namespace.  Is it possible to export the saved searches within the message viewer?

Thanks!

Hi everyone

How can I connect using the Terminal to a remote server?

I changed the server indication on the Healthshare icon on the Windows toolbar.

The management portal works but not the Terminal. When I open the terminal it displays only some information about the server ("SSH-2.0-OpenSSH_7.2p2 Ubuntu-4ubuntu2.2"), but it doesn't give the possibility to log in.

Do you have any suggestions how I could fix it?

Thanks a lot and best regards

Hi community ,

i worked this last time on the access token generate method , now it's ok, i want  use the received access token to have access for asking the resources server.

i found the [%SYS.OAuth2.AccessToken] class which describes how add access token in the http request header , but i don't know how use it in my project.

Do me take only this class or the full package %SYS.OAuth2.

Thank you for helping .

Hello everyone,

From now till the 25th of december each day 2 programming problems to sharpen your programming skills.

http://adventofcode.com/

Theme this year:

The night before Christmas, one of Santa's Elves calls you in a panic. "The printer's broken! We can't print the Naughty or Nice List!" By the time you make it to sub-basement 17, there are only a few minutes until midnight. "We have a big problem," she says; "there must be almost fifty bugs in this system, but nothing else can print The List. Stand in this square, quick!

Let's say I have Macro.Parent class:

Include Parent
Class Macro.Parent
{

ClassMethod Test()
{
    write "Class: " _ $classname() _ $c(10,13) _ "Value: " _ $$$name
}

}

which references Parent.inc macro name:

#define name "Parent"

Now, I want in my subclass Macro.Child to have Test method with the same code, but to redefine value of name macro.

Hello, I will. Cls file (including Chinese comments) directly into the ensemble studio, studio tips imported successfully through the udl file, but my Chinese comment does not display properly, how do I deal with? Thank you!
