#Caché

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

Documentation.

Here is a snippet that I learned yesterday

You can define an index on a collection property but when I tried to use it, I failed. I was using

     Select ….. where …. :xx %INLIST collproperty

But this will not use an index, but the equivalent syntax

     SELECT .. WHERE ... FOR SOME %ELEMENT(collproperty) (%VALUE=:xx)

will use the index

Hi

I am new to cache and accessing it using odbc (other data sources) from excel. I need to know how to get hold of the number of rows for each every object in my current schema.

I can find table name using following query but I need number of rows to estimate size of each table.

SELECT *
FROM %Dictionary.ClassDefinition ClassDefinition

We have noticed in the course of the last 18 days our CACHE.dat has grown by 20 GB. Is there a way we can break down the data in CACHE.dat to see what could be growing in size?

Let me state it another way.....Is there a way to see what space an Operation/Service/Process is taking up within a certain Production?

Thanks

Hello,

I have a property which I need to move from one class definition to another as follows:

Old definition:

Class SCHED.SchedEntry
{
  
  Property Experiment as %String;

  Property ScanSlot as list of TracerEntry;

}

Class SCHED.TracerEntry
{
  
  Property Tracer As %String

}

I want to move the Experiment property to the TracerEntry class so that there is a different Experiment allowed for each ScanSlot, like this:

Looking at the documentation expalining the use of client side menus, including the drop down menu.

I was messing around trying to get the "Open", once clicked, to use javascript to open windows file explorer to open/pick a file.

I've got it to partially work... Using keystrokes Ctrl-O will open the file explorer yet clicking on the drop down's File/Open does nothing.

Not sure what I'm doing wrong here.

NOTE: I had commented out the two &html lines in the Testing Method... and doing a Ctrl-O still work.

Why?

We will be transitioning from a server running HP OpenVMS to one running RHEL 7. The main question some of the team had was what would be the best method for moving the globals to the new system.

Also, I was wondering if any others have transitioned from OpenVMS to RHEL. If so, were there any kinks that we should be aware of prior to transition?

Does anyone know where the default port comes from when installing a new instance on Windows Server 2012 R2?

It constantly picks up the wrong default which is already running on the server (probably swapped over after installation) and the install fails and rolls back.

I installed again and this time without rollback but still allocated the wrong port so at least was able to manually update the cpf and then start the instance.

Would like a simpler solution to the issue and assume they are traversing some windows registry entry that may need updating.

Hi,

My doubt is about the SQL Query in Caché:

I don't want to take all results from the table and orgainze them manually, for example: I have a table with 50 records, but I only want to select 10 records, being from tenth until the twentieth and this without knowing their IDs.

So, how can I do this, without losing performance, there is any way?

Find last in a list of objects

I have a class to track data changes.
As it becomes slower and slower to find last changes I think I need an index.
The 2 classes are just simplified reality.
HowTo ?

Class Rick.ChangeItem Extends %SerialObject
{
Property Subject As %String;

Property Author As %String;

Property Change As %TimeStamp;
}

Hi

Is it possible to include the ≥ or ≤ in a ZEN select component? i.e. 

<select id="condition" label="Condition" valueList="&lt;,&gt;,=,≤,≥" displayList="&lt;,&gt;,=,≤,≥"/>

I have tried &ge; and &le; but these also do not work. If I inspect the options in the browser and edit with these characters they display correctly but just not when loaded in the zen page.

Cheers

Iain

I'm having trouble with a vb6 application attempting to connect to a Cache 2017 release. It uses the older Cacheobject.dll instead of ActiveX. The application currently works with a 2010 release of Cache. Is Cacheobject.dll supported in later releases?

I looked through documentation and posts and did not find an answer.

Thanks in advance for any response.

DigitalOcean API implementation

Recently DigitalOcean introduced new plans for droplets, but as existing droplets stayed on the old plans I decided to use API to resize them automatically. After reading tutorial, I wrote partial client for DigitalOcean API, which I would like to share today.

Testing in studio

After creating a ClassMethod for a routing rule is it possible to test an HL7 message within Studio rather than using Management portal? It would make it easier to debug the custom function to see where the rule is failing.

Hello, I am trying to get the Zen Print Server to work so that i can use the pdfprint mode in Zen Reports. Zen Reports will create pdfs just fine, so that part is working. And the printer works fine from other applications on this computer and I have verified the printer name a bunch of times.

This is Caché 2016.2 on Windows 10. I have tried this using Adobe 11.0 and Adobe DC. I have made and started a Zen Report Print Server with

Name = "ZenPrint"

Port = "4321"

and Ping Port = "4320"
