Hi Community!

Good news! We have a new release of InterSystems Open Exchange.

This release comes with some better options to expose your solutions and tools.

What's new?

✓ Embedded videos;
✓ Screenshots;
✓ Download stats.

See the details below.

I'm connecting to a remote device using TCP. It has a binary protocol.

set host = ""
set port = ""
set io = $io
set device = "|TCP|7000"

set timeout = 2
open device:(host:port:"M")
use device:(/IOT="RAW")
read string:timeout

use io
zzdump string

The problem is when reading from it, I get a 0A (also known as 10 or \n or linefeed) byte, which terminates the read.

Expected output:

0000: 42 00 7B 0A 11

But I get this output:

0000: 42 00 7B

How can I fix that?

I have an existing table, and I've added an array property to it that I need to populate.
The issue is that I can only use SQL to insert into the table due to access reasons.

For example:

Class Package.Tables.Person Extends %Persistent
{
Property Name As %String(MAXLEN = "");

Property Address As Array of Package.Datatypes.Address;
}

InterSystems is currently verifying InterSystems IRIS 2019.1 with Windows Server 2019. This work is scheduled to complete by the end of January 2019. In the second half of this month InterSystems will add Caché/Ensemble 2018.1.2 to be verified on this platform.

As we get closer to the completion of those tasks, I will update this post with information on release dates, and which products and version will support Windows Server 2019.

I try to create a column with computeonchange.

Its works with CREATE TABLE sql command, but if i use ALTER TABLE ADD COLUMN sql command this computeonchange doesn't works.

any reason why?

example:

CREATE TABLE MyStudents ( Name VARCHAR(16) NOT NULL, surname VARCHAR(16))

alter table MyStudents add column fullname Varchar(50) COMPUTECODE { SET {fullname}={Name}_ "?" _{surname}} COMPUTEONCHANGE (Name,surname)

insert into SQLUser.MyStudents (Name, surname) values ('name1',null)

update MyStudents set name = 'name' where name = 'name1'

Hi,

When Creating a custom security role, what privileges do I need to add to it, in order for the users that I grant him the role, to be able to use

dynamic SQL to perform read only queries on all tables in a namespace?

I have a security role, that contains the %Service_SQL privilege,

And yet when I connect to a terminal and try to run an SQL query using dynamic SQL , I get a "user is not privileged for the operation" error.

InterSystems has corrected a defect that impacts the use of X.509 private keys stored in Caché, Ensemble, and Health Connect, but only in 2018.1.1, on any platform.

Hi,

I am having a problem in REST service when de-serializing JSON using a nested Property.

I am new to Intersystems and my first time creating REST Service. I setup Atelier dev environment. The worst IDE I have ever worked in. I was able to attach to a process in the debug perspective and step through the code, but one cannot see contents of variables nor print anything to the console, so it is useless as a debugging tool. When looking at a variable all it displays is its type of the variable and if I try to "watch" I get:

Hello Gentlemen,

As you can read on the title, my question is to know how to retranslate the hl7 message into a string and so to remove the '\E' that are inside. A example/picture worth more than a thousand word.

I'm getting this compilation error:

Kompilieren der Klasse digi.packet
FEHLER #5002: Caché-Fehler: <FUNCTION>zLockUse+5^%ExtentMgr.GlobalRegistry.1
> FEHLER #5030: Während der Kompilierung von Klasse 'digi.packet' ist ein Fehler aufgetreten

when importing one of my classes on the production server into one particular namespace:

In my routine when I call set filestream.FileName = filename, I get an error

"cn_iptcp://localhost:56773/USER/%Stream.FileBinary.1.INT" does not exist on the Server

I successfully instantiate the %Stream.FileCharacter object. 'filestream' value is '1@%Stream.FileCharacter'. But when I debug the code, the step where I try to set the file name fails.

The port number for local host looks good for my current instance. I have tried a few variations, such as using the method FileNameSet(). But this did not work either.

Hi -

I'm trying to follow the documentation, but I seem to end up in a circular reference, where the docs say "Login to TrakCare" to get access to the Layout Editor, with a link to "Logging Into TrakCare", and then that whole sections assumes that the account being used has been created, but doesn't seem to point to any means of actually creating the account in the first place.

Where is it described in the HealthShare Documentation, how to create a TrakCare login account?
