#Caché

45

  

InterSystems Caché is a multi-model DBMS and application server. See more details here.

Documentation.

Hello, our customer, large industrial company, is considering modernizing their old CSP application so it can run on multiple client device types, using responsive design.

They have a lot of experience with CSP and some ZEN.

They are new to REST and have some limited knowledge of javascript - perhaps not enough to the extent used by client framework.

Does anyone have a framework or a set of templates that you would be willing to share?

Thank you!

Hello,

I'm trying to connect to a Caché server from Atelier; the Caché server is 2015.x.

The address and port I'm trying to connect to is the SQL gateway server; and I get, each time, an "unexpected end of file from server".

Note that unfortunately, for the moment, I connect as _system... And the Caché install has the default privileges.

What am I doing wrong?

This is a bit weird. I'm trying to use `DATEDIFF()` to calculate the time since the last message on an interface. For some reason, when no messages are received, the number steadily decreases. This is the opposite of what should happen. Here is my current query and a few sequential result sets:

SELECT getDate() as now, max(TimeCreated) as latest, DATEDIFF (s,getdate(), max(TimeCreated)) as difference
FROM EnsLib_HL7.Message

mySQL data importer tool

Hi,

If you want to import data from a mySQL export file (exported with mysqldump), you will find here a little script that could help.

Only the INSERT commands in the sql file are executed into Caché. Indices are not computed for better performance.
%NOINDEX, %NOCHECK and %NOLOCK are generated on each INSERT line.

Currently, the file can not contain a "),(" pattern inside the values part of the INSERT command. If this is the case, the line is skipped. This feature may be implemented in the extractValuesList method.

Hi -

I'm trying to figure out what is the best (or at least pros & cons) on how to manage login accounts in a multi-tenant SaaS web based application context.

Assume that a company is designing a collections of web based applications that they will be selling as "services" to their clients, and that these clients will each have their own "users" and "customers" that will be logging into these services.

Greetings! This article describes yet another simple way of creating installers for the solutions based on InterSystems Caché. The topic covers applications, which can be installed or completely removed from Caché with one action only. If you are still documenting installation instructions that have more than one step to do to install your application — it’s high time you automated this process.

I am trying to execute a system query. - %SYS.Journal.File_Search()

The Query is looking for a Journal File Name and a String.

However, the Query line accepts no parameters. - Query Search() As %Query(ROWSPEC = "Offset:%Integer")

But in the SearchExecute method if checks for File and String.

ClassMethod SearchExecute(ByRef qHandle As %Binary, String As %String, FileName As %String . . .
{
i $g(String)="" q $$$ERROR($$$JournalFileSearchUndefined)
i $g(FileName)="" q $$$ERROR($$$JournalFileUndefined)

Our company is looking for someone with expert object script skills and experience developing with REST using Caché. We have an existing application that currently supports a mobile application and a web application. The API is up and running but we need another developer to add new features and keep up with demand.

Experience with Amazon AWS is highly desired as the api is running on Windows in EC2. Familiarity with GitHub is also required.

Pay can be negotiated on a per hour basis after you provide an estimate for the time required to complete a given feature.

Hi!

Want to share with you code snippet of try catch block I usually use in methods which should return %Status. 


{ 
 try {
  	$$$TOE(sc,StatusMethod())
 }
 catch e {
 	set sc=e.AsStatus()
 	do e.Log()
 }

Quit sc 
}

Here $$$TOE is a short form of $$$TROWONERROR macro.

Inside macro StatusMethod is any method you call which will return %Status value. This value will be placed into sc variable.

You may experience errors executing Java programs that rely on the JAVA_HOME environment.

For example when Create PDF from this pivot in DeepSee or in this case, outputting a Zen Report as PDF.

You can verify the PDF generation configuration by clicking on the Verify Now button on the Management Portal System > Configuration > Zen Report Settings page:

Good afternoon, I have working prototypes of each of these approaches. I do not have an expansive cache background.

I have a couple of projects where I am ingesting files from disk.

The name of the file contains a lot of the information I will need to reference the file in the future.

Hi,

I sometimes get asked if Weblink will still be available (as a downloadable ad-on these days) for some versions to come.

I realize that this is old technology now, and that there are better and faster ways to do the same things today.

Thanks

Bootstrap's $navbar

Hi, The ZEN Mojo Widget reference at ../csp/sys/%ZEN.Mojo.WidgetReference.bootstrap33xHomepage.cls is a great reference for viewing the different components available with each helper plugin - and it also supplies snippets of JSON code to use in your layout definitions.

I'm having problems with the Bootstrap $navbar component however. This is layout definition, with a navbar and button contained within the bar.:

I was trying to modify the REST.DocServer sample in the SAMPLE namespaces to use the new %Object and %Array system objects (Ensemble 2016.2 build 636) with the following changes:

/// This method returns a list of namespaces for this server

ClassMethod GetNamespaces() As %Status

{

#dim tSC As %Status = $$$OK

#dim tList,tNS,tFilteredList,tValue As %String

#; Get the list of namespaces

Do List^%SYS.NAMESPACE(.tList)

Set tNS="" For {

Set tNS=$Order(tList(tNS),1,tValue) If tNS="" Quit

I get NOROUTINE when I try to call a label in a routine in another namespace:

d someLabel^|”OTHERNAMESPACE”|someRoutine(inputVar,.resultByReference)

Two questions:

1. What is wrong with my syntax for calling a label in the other routine, versus just the root of the .int/mac?

2. Can I pass a parameter by reference when using extended routine reference?

Hello,

It is time for me to eat my own dog's food and start implementing unit test running with coverage :) I will be inundating IRC with questions at this point, but I have a more general question first.

In this tutorial, it is supposed that your unit tests are exported as XML first... But that's not very practical. Is there a way, instead, to run all tests from a given project without having this export?

My first thought on how to do this would be to:

Hello,

Still related to the unit test with coverage support project, one goal is to make that package available to everyone.

One possible way I already know of is that all fully qualified class names (ie, the package + the class name) start with %, which mean that on installation all classes will end up in the %SYS namespace, but this requires that the install be done as a user with the necessary privileges to write to %SYS.

Has anyone noticed that the Feature Map and Master Index was dropped from the 2016 version?

Anyone know why?

Please see the attached file of a screen shot.

Well, I have a screen shot file, but when I try to up load .docx, or .pdf, or html I am prevented, don't know why?

Yes, frustration!

I have two servers in our TEST environment. One with HSBUS and one with HSREGISTRY. Let's call them "HSBUS01" and "HSDB01" respectively.

Now, I can access HSBUS with my SQL client by using the JDBC driver pointed to hsbus01.full.name.com and port 1972 and specifying a namespace of "HSBUS". I am, however, unable to access the HSREGISTRY instance via SQL with a similar combination of information.

We have a query that looks something like:

select a, b, c, d, e, f

from tbla inner join tblb on tbla.....

This query runs in the expected 200-400 ms range.

If we run the same query but reduce the select to just:

select a

from tbla inner join tblb on tbla.....

then the query runs for 30 minutes or more.

The rest of the query is identical. Is there a logical explanation for how this can happen?

Thanks.

I have to disect thousands upon thousands of strings like this:

96842-2-AEV.00001-63561-001958-100728760I-42

I've been able to pull out the first, second and final segments as separated by hyphens, but now I have a predicament where I need to use the second segment, the 2 shown in the example above, in a join to another table. Problem is Cache apparently doesn't like doing that. Just the same, I have to find a way.

Here's the code I'm using to pull that segment out into as separate field in the query results:
