Suppose you have developed your own app with InterSystems technologies stack and now want to perform multiple deployments on the customers' side. During the development process you've composed a detailed installation guide for your application, because you need to not only import classes, but also fine-tune the environment according to your needs.
To address this specific task, InterSystems has created a special tool called %Installer. Read on to find out how to use it.
Does Caché support a relationship property ordered according to a specifc value?
What shoud be the best approach?
The attached file contains an example of code generation using ObjectGenerators which builds a very simple homemade RuleEngine.
Code generation is an excellent way of increasing performance moving run-time calculations to compile-time.
We could generate code creating routines or implemeting methods using ObjectGenerators. In this example we are using ObjectGenerators.
Update: Rule Engine is now on GitHub https://github.com/intersystems-ib/cache-iat-ruleengine
This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!
Is there a way to iterate ClassMethod's params, and get param's names and values?
The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):
The cache has error messages default, for example , " -139 SQLCODE : Competition impairment on the update: row versions are not the same. "
How i can exchange it for a more friendly to the user's message? I use the CSP.Page and form_save ( ).
What is best practice for this situation?
Caché Monitor is a database\sql tool primarily for InterSystems Caché but can also connect to MS SQL Server, MS Access and more databases. Within Caché Monitors Server Navigator you see all available Namespaces on your Caché Servers. No need to know the name of the Namespace, no need to configure many many JDBC Connections by hand. Just click on the namespace and see all objects like tables, views, classes and more...
XData blocks in Caché classes has a MimeType property, and dcoumentation says
MimeType — The MIME type (more formally, the internet media type) of the contents of the XData block. The default is text/xml
Hello,
I am trying to use %ZEN.proxyObject to send out in JSON format so I do:
set tProxyRequest.notanumber = "28001"
set tProxyRequest.aboolean = "true"
set tBody = ##class(%GlobalCharacterStream).%New()
do ##class(Ens.Util.JSON).ObjectToJSONStream(tProxyRequest,.tBody,"aelotwu")
w tBody.Read()
and I get:
In preparation for a presentation I need a real-world LDAP schema that has been customized a bit beyond the basics. Perferably this would be based on an OpenLDAP system which would make it easier to merge into this presentation.
If you have such a schema you would be willing to share please respond or contact my directly at Rich.Taylor@InterSystems.com
Thanks in advance.

Here is my original query:
SELECT EventType, InitiatedAt, COUNT(*) as cnt FROM HS_IHE_ATNA_Repository.Aggregation WHERE EventType = 'LOGIN' AND LocalDateTime > '2016-02-16 11:00:00' GROUP BY EventType, InitiatedAt
This gives me data like this:
I'm interested in different approaches on how to store user data in Caché. I'm assuming that application uses Caché security/Caché users and not a self-made authentication system.
Several approaches, I'm familiar with:
I'm revisiting some older projects that can benefit from the new JSON support and dynamic object capabilities in 2016.1 FT / 2016.2 FT. (Particularly, some of the really new features in the latest 2016.2 FT.)
For the particular thing I'm working on, it would be very handy to be able to merge objects, similarly to https://api.jquery.com/jquery.extend/. The closest thing I've found so far (in 2016.2 only) is:
Set o1 = {"a":1,"c":2}, o2 = {"b":1,"c":1}
Write "o1: ",o1.$toJSON(),!
Hello,
I am trying to log the output of csession in Linux. I try this command:
csession cache | tee myoutput.log
Although it works each new lines at screen output doesn't appear at row 1...
Any tip?
I am pleased to announce the third 2016.2 field test kit, 2016.2.0.590.0.
In the week since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché. Unlike the previous field test kit, though, in which the changes were distributed evenly over multiple areas and products, in this kit over half of the changes are associated just with Atelier.
I've searched the ObjectScript reference for any instances of Upper, Lower or Case and the only thing is a case/switch statement. In all the documentation I can only find SQL and Cache Basic references for things like UCASE.
So how do I do this in ObjectScript?
Has anyone come up with a way to create a separate thread of processing that can achieve shared access to a set of objects created from the initials process? The situation is this. There is a large complex set of objects representing a business process. Some of these objects are in-memory only. The desire is to spin off a separate thread that could do some ancillary processing on this data set without slowing down the main process. Any thoughts?
Hi!
Are there any plans to support Kerberos authentication in Atelier to Caché connection?
Thank you.
Do to unforseen circumstances the Atelier build that was distributed with the Cache 2016.2 field test had certain incompatibilites which prevented it's effective use with the server that it was bundled with.
We are working on remediating this regretable situation and will provide a compatible Atelier in the 2016.2 field test refresh which is scheduled for today Monday, 1st of Februrary.
We sincerely apologize for any inconvenience so caused.
Hi,
Do you know how to export SQL errors to a text file from a terminal session in Caché?
Thanks
I'm designing a workflow for PHR via FTP. What I've done is create a single FTP adapter to pick up files from multiple customers. A router then accesses a lookup table and determines if a particular customer is allowed to send a particular message type to the state. If not, the message doesn't go out. It seems like everyone is against this approach (other than my CEO, thankfully), including Intersystems:
I am pleased to announce the next in the series of 2016.2 field test kits, 2016.2.0.585.0.
In the two weeks since the last field test posting Development has made over a hundred fixes and improvements in Atelier, Enterprise Manager, Ensemble and Caché.
In Atelier alone there were over a dozen changes including a fix for the incompatibility issue that Jamie Newton described in his posting of February 1.
In Caché major areas of focus include:
What do you do if you want to have the ID field have a meaningful name for your application?
Sometimes it comes to pass that when you're making a new table that you want to have the unique row identifier (a.k.a. IDKEY) to be a field that has a name that is meaningful for your data. Moreover, sometimes you want to set this value directly. Caché fully supports this functionality and it works Suppose you have a class Test.Kyle. The data will be stored like so:
^Test.Kyle(IDKEY)=$LB("",Field1,Field2,...,Fieldn)
Some third party backup products may by default restore CACHE.DAT files as UNIX sparse files when there are trailing zeroes in the backup file.
The support for sparse files vary from UNIX distribution and file system types. Sparse files attempt to use file system space more efficiently when blocks allocated to the file are mostly empty similar to thin-provisioned storage. The file system transparently converts metadata representing empty blocks into "real" blocks filled with zero bytes at runtime. The application is suppose to be unaware of this conversion.
Hi,
I created with Studio a persistent class with the following field and index:
Do you need to quickly build a web page to interact with your database?
Take a look at these two courses to learn how Zen Mojo can help you display collections and make your collections respond to user interactions.
Displaying Collections and Using the Zen Mojo Documentation
Learn the steps for displaying a collection of Caché data on a Zen Mojo page, find crucial information in the Zen Mojo documentation, and find sample code in the Widget Reference. Learn More.
As of this morning, 38 companies had already grabbed a copy of Ensemble or Caché (Caché is more popular by about 3:1 ratio) to explore the new features of 2016.2.
Thanks - we look forward to hearing your feedback.
