Hi guys

I've added a new mirrored failover member to an existing one.

They are both Arbiter controlled.

When I do Add database to mirror on the primary I'm always getting an error. Missing Mirrored database.

I followed everything in the documentation and always get the same error.

I've copied the CACHE.dat file after umounting the database on both servers. then mounted them.

Could you help me out?

Kind Regards

I know it's late, but I really love the advent of code theme each year to find some project ideas to go out and code something and push myself.

I had the intentions of completing the AOC 2018 before the new year, but I've got 2 young kids (1yo and 4yo), so most nights I just want to sleep.

I've been looking at this on my half hourly commute each day before and after work.

So whilst doing this, I found not many people had posted what they had done and in previous years.

I'd found this helpful when I've got stuck for ideas, so I thought I would post what I've done (that works) and see how others

I have one abstract class and several subclasses. All share one data/id global.

How can I get concrete class name from id (without opening the object)?

What I have so far:

write $p($lg(^DATAGLOBAL(<id>),1),"~",*-1)

It does the job, but is there a more official way?

ˮ This is one of my articles which was never published in English. Let's fix it!

Hello! This article is about quite a practical way of developing InterSystems solutions without using the integrated tools like Studio or Atelier. All the code of the project can be stored in the form of "traditional" source code files, edited in your favorite development environment (for example, Visual Studio Code), indexed by any version control system and arbitrarily combined with many external tools for code analysis, preprocessing, packaging and so on.

The approach described in this article is suitable for

I have a problem,ExtentSize,Selectivity etc is stored in class definition.

I have multiple namespaces with globals maped and only one class definition for All, for example Orders.

Order definition is only one,mapped to main namespace,but in different namespaces have different ExtentSize etc.

Here's a simple indirection snippet. It fails with <UNDEFINED> error and I'm not sure why.

ClassMethod ind()
{
  kill info

  set active = 1
  set reactive = 2

  for i="active","reactive" {
    set info(i)= @i
  }

  zw info

  break
}

I'm getting this exception: <UNDEFINED>zind+5^test.Client.1 *active

In this series of articles, I'd like to present and discuss several possible approaches toward software development with InterSystems technologies and GitLab. I will cover such topics as:

• Git 101
• Git flow (development process)
• GitLab installation
• GitLab Workflow
• Continuous Delivery
• GitLab installation and configuration
• GitLab CI/CD

In the previous article, we covered Git basics, why a high-level understanding of Git concepts is important for modern software development, and how Git can be used to develop software. Still, our focus was on the implementation part of software development, but this part presents:

• GitLab Workflow - a complete software life cycle process - from idea to user feedback
• Continuous Delivery - software engineering approach in which teams produce software in short cycles, ensuring that the software can be reliably released at any time. It aims at building, testing, and releasing software faster and more frequently.

Hi,

I have a custom classes that that I use with EnsLib.SQL.OutboundAdapter to convert HL7v2 messages to SQL INSERT statements to write results to an SQL database.

Weirdly the management portal is not drawing the the lines between my process and operation when viewing my production on the ' Ensemble > Production Configuration' screen.  Clicking the green dot flashes the 'computing connections' message, and highlights my operation, but no lines get rendered: 

I am using custom classes, but they extend Ens.Request, Ens.BusinessProcess and Ens.BusinessOperation so I'm confused why the lines are

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 like to know if COS has a PGP library for encryption and decryption messages received from an SFTP connection. We have  interfaces that we used BouncyCastle in C# but would like a native library for COS.

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?

Some additional info:

• read completes in 0.1 seconds despite 2 seconds timeout.
• $zb contains the value of 0D

Good afternoon,

We have a very old version of Ensemble with one of our clients and they have no desire to upgrade anytime soon. We have gotten the all-clear to purge really old messages from the database, changing the days kept from 60 to 30. The option to Compact/Truncate is displayed in this version of Ensemble, but does not execute as it mentions not being actually present in this version.

There is an option in ^d DATABASE that restores unused space, however this does not return nearly as much free space as the refined Compact/Truncate procedure.

My question is: Is it possible to

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;
}

Class Package.Datatypes.Address Extends %SerialObject
{
    Property AddressType As %Integer;
    Property StreetAddress As %String(MAXLKEN = "");
}
                
So the projected tables are:

Package_Tables.Person
Package_Tables.Person_Address

Now via ObjectScript it's as easy

Hi Community!

Please welcome a new video on InterSystems Developers YouTube Channel:

Developing with FHIR - REST APIs

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 am taking over a production system that had some HSLIB and other database routine and class files modified. However, I do not know what was modified .

I developed a routine that allows me to load each database in our production instance and compare it against a default instance using the SIZE attribute. This allowed me to generate a list of files where the .INT file size in production does not match the file size in the default instance. However, doing a spot check of the .cls or .mac files indicates that in some cases these files are identical, just the intermediate files are different.

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'

this not updates fullname column value....

but it's works with a

Hi,

I know of the existance of (ELEMENTS) to create an index from a list, but I actually would like to index the content of an element of a list. Is it possible?

My scenario:

Class:
Property Test As list of TestList;
 

Test.List:
Property Name As %String;
Property Surname As %String;

I would like to have an  index based on the TestList.Name. If I try using

Index NewIndex On Test(ELEMENTS)

it will create an index with Name and Surname in it, but I just want to have an index with the name. Is it possible? 

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?

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.

reading the documentation , I understand that %Service_SQL privilege privilege is not enough, but I don't understand what privilege to add,

I can't add specific tables in the

Hi, I have a CSV file with a list of 5000 records in the following format

Name, Acc, division

Eric, 1234, 567

John, 1235, 987

I just want to copy the Acc, division to a global so eventually the global would be like the following:

^People("Customers", "Acc.division")

Can you advice on how I can perform this from the terminal? This is a one time task. I want to read all the values from the csv file and insert them into the global

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.

This defect does not affect new installations of 2018.1.1, only upgrades to that version. It affects WS-Security, not SSL/TLS Configurations.

If your environment uses X.509 credentials with private keys and has been upgraded to 2018.1.1, some functions and queries that use the private keys will fail. To correct this problem, please contact the Worldwide Response Center (WRC) and request the utility developed to address the issue.

InterSystems has corrected a defect that can result in data integrity problems in environments that use InterSystems mirroring in conjunction with parallel dejournaling. This problem exists for currently released Caché and Ensemble versions beginning with 2017.2 and for InterSystems IRIS Data Platform version 2018.1.

Ensuring that you are protected from this issue

Your system is at risk only if you have a mirroring environment that supports parallel dejournaling for mirrored database catchup.

I'm trying to test SOAP integration by using one Ensemble production to send a SOAP message to another production, but I'm seeing the following error when I try to pass a message between the two:

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.
OBX|1|RP|ECG||CARDIO ECG^APPLICATION^PDF^^\E\\E\sitehopital.org\E\files\E\cardio\E\022018\E\GE274583.PDF|

As you can see, the escape character \E is used by hl7 message in the purpose to authorize a character '\' just but I don't want it in my program... Is there any function that retranslates this format into a "normal" format?

Faithfully,

Thomas

I am reviewing some code where the % sign has been used liberally to name arrays that are worked on by different methods within the same class. Apparently it is not good practice to name variables with a "%" sign as the first character because this could overwrite other similarly named variables from other developers, including ISC!  Is there another way to make a variable public ? 

I'm getting this compilation error:
