creating a test server

hi, new here, and new to cache and deepsee.

i've been trying to setup a copy of our production server so we can use it for testing/development.

i did a full backup. moved it to the new server. ran the DBREST command. got it to restore but seems like permissions get all messed up. and it just generates a bunch of errors.

is there an easier/better way of doing this?

Parallel execution in COS

Hello community,

I need to perform some processing-heavy operations on a set of input objects and I would like to utilize more than a single processor core to do the heavy lifting.

Is there any way to call methods in parallel and wait for the results in a blocking way?

Basically, I am looking for an equivalent of the pythonese

with Pool(n) as p:
results = p.map(function, data)

Thanks

Jiri

EDIT: Correct English :)

UNC path not recognized

Hi Guys,

The Path is accessible via windows explorer with no issues (\\backupsvr) and also my works fine when using :

O C:\folder\file.txt:("WNS"):5

I have one in my testing environment. According to https://community.intersystems.com/post/licensing-ubuntu-and-suse-20171-and-later, I should move to native Ubuntu build with 2017.2. So I downloaded Cache for UNIX (Ubuntu Server LTS for x86-64) 2017.2.1 and tried to update my existing 2015.1.4 installation. What I got was:

Upgrade from lnxsusex64 platform is not allowed.

It is often necessary to sort the results of a query on a string field containing a combination of alphabetic and numeric characters. In cases like this the default string collation may not always return the data in the expected sequence.

An example of this may be where a select from Samples.Person should order the results by the street address, but firstly ordered by the street number part as numeric, and then by the street name.

The default query will return the results as follows:

HI,

Has anyone implemented the NHS Care Connect profile in HealthShare and if so could you share the steps you took?

I am not looking to integrate it into the SDA model, Just looking having the classes within HealthShare and then applying a DTL to convert to HL7 2.x

I was hoping i could just down load the profiles from git hub and import into Studio but it appears I need the XSD to do this, which are not available.

Cheers,

Jason

Hi-

I have searched through documentation, etc and see many mentions of using Ensemble / Health Connect along with the Java Gateway to interface with JMS Queues, but see no specific documentation on how to do this.

Does anyone have any information, or a concise example of using the Java Gateway to allow Ensemble / Health Connect to be able to place messages and retrieve messages from a JMS Queue?

Thanks

M:N Relationship

If you have worked with Caché Objects,
You know already all about Relationships (one:many , parent:child) ...
But you will not find a word on many:many relationships in the docs.

But I met the question quite often from new adopters of Caché objects:
"Is it possible to implement many:many relationships ?" YES - of course !
