Discussion David Little · May 16, 2017

Hi All

I'm looking for some field experiences, lessons learned, or actual deployed solutions to the problem of replicating non-CACHE.DAT data in a mirrored Cache environment.  

Environment:

  • Operating System is IBM AIX
  • Hardware is IBM Power w/ virtualised storage
  • Cache 2017.1
  • 2x Production mirror members
  • 1x DR mirror member

There are a number of different data types that we're looking at mirroring, and a number of identified solutions.

Most frameworks support either REST or WebSockets, and don't make it easy to switch between the two, and/or support both styles of application at the same time.  WebSockets offer many advantages over REST, eg:

- most benchmarks show WebSocket messaging to be significantly faster than over HTTP

- you break free of the HTTP Request/Response protocol limitations, allowing the server/back-end to send messages to the browser as and when it wishes, not simply when polled by the browser.

Question wx fg · May 22, 2017

hi

   I want to online backup one Caché database by windows bat, I find some article from the online documentation about  terminal script and the ^DBACK tool and External Entry Points for ^DBACK,  so I can invoke the External Entry Points for ^DBACK from terminal  script like this:    send: Do BACKUP^DBACK<CR>

Is there other better way for backup database from bat/script?

Thanks

This is a translation of the following article. Thanks @Evgeny Shvarov  for the help in translation.

Let's assume that you wrote a program that shows "Hello World!", for example:

  write "Hello, World!"

The program works and everyone is happy.

With time, however, your program becomes more complex, gets more features and you eventually need to show the same string in different languages. Moreover you don't know the number and names of these languages.

The spoiler below contains a description of how the task of multi-language localization is solved in Caché.

Hi everyone,

This is:

Cache for UNIX (Red Hat Enterprise Linux for x86-64) 2016.2 (Build 736U) Fri Sep 30 2016 12:25:56 EDT

The server is on RedHat Linux while the browser is running on Windows (Firefox).

I am helping a partner build a complex modern HTML5 web application that talks with Caché using REST calls. They have been using %CSP.REST very successfully. Security works great as well. 

Some time ago, I had defined the parameter CONVERTINPUTSTREAM = 1 on their %CSP.REST classes and that seemed to work.

I am trying to set up a sensor in PRTG to connect to Cache, specifically the ens_util.log, so that I can have a live feed of my error count. I am having trouble getting the sensor to log in to Cache. Has anyone had any luck getting PRTG to connect on the database level? Thanks!

Question Graham Hartley · May 17, 2017

Hi,

Is there a way you can limit the amount of physical memory Cache uses?

During Cache backup it appears that all the available memory on the server is being used.

We are running Ensemble 2016.1 on Windows Server 2008 R2 with 32GB of RAM.

The database we are backing up is about 300GB.

Thanks,

Graham

Question Raghuram Devarakonda · May 18, 2017

Hi,

I am trying to support a use case where a test instance is created from a production backup.  At a high level, the process works by mounting all relevant file systems and then bringing the instance up. This works well as long as the file systems are mounted using same mount points as the source instance. However, I would like to support a case where file systems are mounted using different paths. 

For example, if the source instance uses the mount points "/cache" and "/cachejournal", assume that the restore process mounted the same file systems at "/cache_123" and "cachejournal_123".

I am getting an ERROR #5002 in a soap service defined in ensemble. Odd thing is that I allready have a functioning business service running as a soap service, but we needed another, but that one returns an error:

<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:s="http://www.w3.

Question Mitch Anderson · May 16, 2017

Hey guys,

I'm working with an EnsLib.XML.X12.Document object which consists of a parent object along with multiple children.

When using the following code, my sent object is losing all references to its children.  I've played with the deep parameter and nothing is working to automatically clone the objects children(group docs ref)along with itself.  (Even though the documentation states that it should..)

objectClone = object.%ConstructClone()

d ..sendRequestAsync("Destination",objectClone)

Any insight would be really helpful.

Thanks!

Mitch

About the Ontodia library

First of all, I think we should provide some background information about Ontodia and Caché DBMS. Let’s start with a less known product, Ontodia. Ontodia is the result of a joint project of the ISST lab of the ITMO University and VISmart, a software development company specializing in the semantic web domain. The Ontodia service was created as a web application for visualizing linked data and ontologies. We created this service because we couldn’t find simple, accessible and efficient tools for convenient visualization of linked data.

Question Eric Hansen · May 15, 2017

I am trying to apply a temporary time-limited key for our organization to a Cache Server that I built out a few weeks ago for testing purposes. When I navigate in the portal to activate a new license key, I get this "ERROR #8610: License keys are not accepted on a Single User (SU) platform."

Is there something I need to do for this system in order to make it compliant for the key or do I need to request a new key from InterSystems that will work for this system? I didn't turn up anything on the web site here or via Googling the error and error text.

Question P Patz · May 12, 2017

Looking for a way in which I could possibly pass a flag through a property when performing an Insert statement, on a mapped class.

insert into my.class (serialNumber, modelNumber, myFlag) value ('testSerial', 'testModel', 0)
    myFlag is not stored in the DB.

The mapped class then calls a legacy routine (MAC) via CodeMode = 'objectgenerator', (Insert method within the 'objectgenerator')

Within the legacy routine, I am setting an index... but I don't always want to set it (multiple inserts, and I will only set the index on the LAST insert)

How can I pass that flag through the insert

Wanna Cry

Most of you should be aware that the Wanna Cry virus is massively infecting un-patched windows machines all around the world. It's particularly affecting the NHS, one of my main clients. 

Wanna Cry is one of a line of Viruses that exploit SMBv1 over ports 135 and 445.

A kill switch has been enabled, but this won't protect machines sitting behind http proxies, and there are already reports of new versions without a kill switch.

All windows machines should be isolated and updated a.s.a.p. 

If automatic updates is not on, a patch can be dowloaded from here...

<spacer width="5"/>
<text id="CountryName" name="CName" label="Country" size ="24" />
</hgroup>
<spacer height="5"/>
<button caption="Search" onclick="zenPage.searchValue();"/>
</page>
}
ClientMethod searchValue() [ Language = javascript ]
