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

Documentation.

Hi folks,

One of my clients want to project a null property of a cache object to an empty XML element. Say, if we have a class:

Class Diabetes.BS.Message.LabReportMessage Extends Ens.Request
{

Property Report As %String;

Property IsRisky As %Boolean;

Property RiskValue As %String ;

}

If the instance of this class has a null RiskValue, after projection, they want the XML as following:

I have a CACHE.DAT file that is working under CACHE version 2015.1.0.429.0

I have a second machine with CACHE version 2017.2.0.741.0

When I attempt to add/use the CACHE.DAT in the new version of CACHE, it will not mount.

How do I upgrade/convert the DAT file to make it work under the new CACHE version?

Thx. Larry...

1) I have an oref pointing to an object on disk

2) I save the object which causes an UPDATE / AFTER Trigger to fire, and updates a value in an embedded object property

3) I would like to see that new embedded property value in my in-memory object (for unit testing)

Is there a way to do this via a method call? Or do I need to close the object and re-open it to see the updated value?

Thanks!

Ben

I have a serial object:

Class EmbedObj Extends %SerialObject

which is stored as a property of another object

Class ContainerObj Extends %Persistent

Property InnerObj As EmbedObj;

Property Foobar As %String;

Question:

From within the context of an instance of EmbedObj, how can I navigate to the containing instance of "ContainterObj" and find that value of its Foobar property?

Connect to hardware

Hello,

If this question is in the wrong section, I apologise.

Has anyone ever used Cache Object Script to connect to any hardware such as a sensor?

What I mean is this :-

Lets assume that code has been written in Cache Object Script where it can detect breaks in electrical connections.

I've set up a Ens.Alert routing rule and would like to route alerts to different email groups based on business partner or alert group instead of relying on source config using Document.SourceConfigName. Is there a way to reference the business partner or alert group property in a routing rule?

We are updating from 2015.1.1 to 2017.2. I am testing the Hot JVM functionality to see if our current functionality is working in the new version of 2017.

I am having a problem trying to make it "fail".

Generally if I put in an invalid renderport then I usually get an error. Now if I put in an invalid renderport it generates the PDF anyway (FOP).

Was there a change where if it fails using the renderserver then it will create a new instance of Java to produce the PDF?

Hello All,

I hope it's not a silly question.

Here is my issue:
I have 3 simple classes:

Parent class, let's say:

Class ParentClass Extends %RegisteredObject
{
Property a As %String;
}

and two children classes
Class A.Child Extends ParentClass
{
Property b As %String;
}

Class B.Child Extends ParentClass
{
Property c As %String;
}

So no issues - all compiles and seem to work.

But, when I add %XML.Adaptor to my parent class, so:

AddEventListener for a control

Is there a way to add event listener for a zen control?

I have a custom text control and I want to add 'change' event listener for it.

Is it possible to do not using 'onchange' property?

The use of the InterSystems Virtual IP (VIP) address built-in to Caché database mirroring has certain limitations. In particular, it can only be used when mirror members reside the same network subnet. When multiple data centers are used, network subnets are not often “stretched” beyond the physical data center due to added network complexity (more detailed discussion here). For similar reasons, Virtual IP is often not usable when the database is hosted in the cloud.

Network traffic management appliances such as load balancers (physical or virtual) can be used to achieve the same level of transparency, presenting a single address to the client applications or devices. The network traffic manager automatically redirects clients to the current mirror primary’s real IP address. The automation is intended to meet the needs of both HA failover and DR promotion following a disaster.

Time after time on CSP Session page of our Cache 2017.2.1 installation I see that all licenses are consumed by CSP sessions of /csp/sys, /csp/sys/op/and /csp/sys/mgr applications which I assume are sessions of Management Portal. The problem is that there are only few of us accessing the Portal and as we test by browsing Portal, we can't reproduce the problem.

Is there any way to see client IP of CSP session? Any other way to approach the problem?

The problem looks very similar to the Forefox-related one but we don't use Forefox.

Hi Everyone,

I am trying to built a SSIS package thru BIDS Visual Studio 2013. My Datasource is a InterSystems Cache Database, I wanted to Import Tables records from the Datasource to MS SQL Server 2014.

As a Sanity check. I only created one Package to import one Table to MSSQL Server to try out. The connection to the InterSystems Cache Database was successful. The DSN for the InterSystems Cache Database is created in the System for 32 and 64 Bit.

Caché service does not start

Help, after a day of coding, I wanted to backup my files. I found out that alle of my 3 instances of caché refuse to start.

the error says: cstart-exe-fout (112 Service for Caché instance did not start).

Is there a way to solve this? (off course the management portal does not work either.)

I think there has been a power interruption as the battery from my laptop does not work, and the power went off before

shutdown.

Thanks in advance!

I have a cache client with a list of several servers.

One of the server is working with an IIS server that is not the Cache DB server.

The connection to the IIS server is only through https (SSL)

I tried to define the Web Server IP Address to https://some.server.name but it didn't let me to specify the https

So I tried to define Web Server Port to 443 but when I chose the SMP it's trying to open http://some.server.name:443/csp/sys/UtilHome.csp

Hi - has anyone successfully used the python binding on a mac. I carried out the install instructions per InterSystems documentation and it fails completely. 204 warnings and 9 errors. Obviously this was never tested by InterSystems. Is it even worth pursuing?

Thanks

Send PATCH http call

I need to send a PATCH call from the server to a given url.

Until now I was using %Net.HttpRequest to issue calls for get/post/put but today I had to make a PATCH and I can't find a way to do it.
