Here are a few examples of conversions and operations you might need, along with links to documentation where you can learn more.

At the time I wrote this, Eastern Daylight Time was in effect for my Caché system.

How Caché keeps the time and date

Caché has a simple time format, with a longer range of recognized dates compared to some other technologies.

The current time is maintained in a special variable $HOROLOG ($H):

Good day!
Is there an opportunity to debug the ISCAgent behaviour (in Linux)? ISCAgent uses /etc/iscagent/iscagent.conf as configuration file, but in docs I've found a description only for two parameters (port number and interface - http://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=...). Other parameters I can see by running /usr/local/etc/cachesys/ISCAgentCtrl status:

There is an interesting discussion in the Russian forum going.

What is the best solution for the function which returns the max for the set of parameters?

From the listed solutions I like this one:

ClassMethod max(args...) {
  for i=1:1:args {  s max(+$g(args(i))) = i }
  s i="", max=$o(max(i),-1, i) Q $lb(max, i)
}

I'm working with a custom code in Studio and I'd like to know where a Class is being used.

The standard ctrl+f search only in current file.

Hi,

We are finally planning to migrate some ancient Caché applications that are run on Caché 5.0.21 to a new server with Caché 2016.2.0 or so.

I wonder if we could use Shadowing between those to keep the data on the new server up to date?

We would copy the Caché backup from the old environment to the new and do a RESTORE there and then start shadowing.

I know than 5.0.21 is no more officially supported by ISC.

We at George James Software recently released a new version of Deltanji, the native source code management tool for Caché, Ensemble and HealthShare.

Version 6.1 includes several enhancements, including easy creation of labels. Bulk transfer of large codesets is also now available from the browser UI.

A perpetually free "install and go" Solo Edition of Deltanji is available. Licenses can be purchased for other editions that provide more advanced code management and deployment features.

Deltanji is compatible with Atelier. It can also manage external files.

ISCAgent is automatically installed with Cache, runs as a service and can be configured to
start with the system. This is fine – but the complication comes when this is on VCS clusters with
Mirroring on. When installing a Single Instance of Cache in a Cluster, point number 2. Says “Create
a link from /usr/local/etc/cachesys to the shared disk. This forces the Caché registry and all
supporting files to be stored on the shared disk resource you have configured as part of the
service group.”

NewBie's Corner Session 22 Parameters Part III

Welcome to NewBie's Corner, a weekly or biweekly post covering basic Caché Material.

Parameters

In Sessions’ 20 and 21 on Parameters we saw how to call one routine from another with parameters as well as calling one Label from another with parameters. In these examples, the data was passed through the parameters from the calling routine or label to the called routine or label.

Now suppose you wanted the called routine or label to pass data back?

Hello,

I'm a beginner in HealthShare, and I start to develop with caché some dataflow.

Some of my business process exist in java code.

Is-it possible to call these packages from caché classes ?

If it is, how can I do it in Caché classe ?

Thanx

I had a table which contained data and worked fine, without changes the code of the persistent classes I now get the following error:

Hi,

When we write unit test cases for cache object script code using %UnitTest.TestCase, what is the best way to write code to identify code coverage?

So, let say my unit test case hit all 10 lines of code of a method for a given class. So, unit test coverage should be 100% for that. But, using line-by-line coverage [(%Monitor.System.LineByLine] getting wrong percentage, because it also includes code comment/documentation as part of code. So, practically we can not ever achieve 100% of code coverage by using this API.

This tells me that there is no timezone offset on this table/field:

In this article I would like to tell you about macros in InterSystems Caché. A macro is a symbolic name that is replaced with a set of instructions during compilation. A macro can “unfold” in various instruction sets each time it is called, depending on the parameters passed to it and activated scenarios. This can be both static code and the result of ObjectScript execution. Let's take a look at how you can use them in your application.
