Other Sync-Tools just work from Caché/IRIS to Caché/IRIS.
Synchronizing your data to some external DB requires some other solution.

The solution is available in Caché/IRIS since quite some time and works excellent.
^OBJ.DSTIME does the magic.
https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=D2IMP_ch_current#D2IMP_C23869

It was built to allow data synchronization with DeepSee.
It keeps a very simple journal on Object/Table changes by signaling Modified,New,Deleted
This could be useful not only for DeepSee but for any other type of Table Synchronization.

Question Neerav Verma · Mar 26, 2019

Let's say we have a class 

AbcRequest extends Ens.Request, PropertiesBaseAbstractClass(has all my properties common to all request)

Prop1

Prop2 and so on

Now in my Business Operation 

I want to make a json dynamically from this request.

Yes obviously I can do is

Set requestDefinition = ##class(%Library.CompiledClass).%OpenId("MyCreateRequest")
Set JsonObject    = ##class(%DynamicObject).%New()

I have an application using examples from the lottery example in samples name space how do I create a dynamically link based on the data displayed to add a record id to the link

the idea is to loop over the records displays fields and link to edit the shown data at the end of the record in a table format

Question Chris Thompson · Mar 21, 2019

We would like to know if there are any ramifications swapping out our code database while an Ensemble production is running. We are trying to minimize down time as much as possible and even though stopping and starting the production ideally would be pretty quick, is it possible that we could just restart the business hosts that had the code change?

So this is our setup: Ensemble 2016.1

global cache.dat code1 cache.dat code2 cache.dat

Namespace that we switch to point to either code1 or code2 and is mapped to the globals.

Hi

We have just completed a migration of a test environment from Ensemble 2012 to Ensemble 2017 on a new server. This is the last in a series of migrations but the first to encounter this particular issue. All web clients making SOAP requests to a particular external web service are receiving a fault that states:

The SOAP action specified on the message, '', does not match the HTTP SOAP Action, 'http://<expected target service action follows here>'.

Question James Davidson · Mar 20, 2019

I've seen a few password change posts, but I wasn't 100% sure it was the same process, so I am asking here. We periodically have to change the passwords for a few Cache user accounts across several servers. Is there a process/script to change these passwords without having to go into the web portal on each server?  Thanks so much, and I apologize if this was covered in some of the other articles that I've run across. Just looking for the best method.

Question Scott Roth · Mar 20, 2019

I am having an intermittent issue that when I make a call to MSSQL from a BPL that the response does not come back in the amount of time required. Since the call from the BPL is synchronous I tried changing the timeout to 60 but it has not helped (see below). Is there anyway to guarantee that the call waits long enough for a response before continuing on?

Thanks

Scott Roth

This is a continuation of my story about the development of my project isc-tar started in the first part.

Just having tests is not enough, it does not mean that you will run tests after all changes. Running tests should be automated, and when you cover all your functionality with tests, everything should work well after any change in any place.  And Continuous Integration (CI) helps to keep the code and deployment procedure with as fewer bugs as possible and automates the routine procedures, like publishing releases.

I use GitHub to store the source code. And some time ago GitHub started to work on its own CI/CD platform and named it GitHub Actions. It is not widely available, yet. You have to be signed as a beta tester for this feature, as I did. GitHub Actions uses quite a different way how to deal with a build workflow. What is important that Github Actions allows to use Docker, and it’s quite easy to customize available actions. And interesting that GitHub Actions is really much bigger than any classic CI like we have in Travis, Circle or Gitlab CI and so on. You can find more in the official documentation.

Question John Peeke · Mar 19, 2019

Hello all,

I am having some issues creating a docker image with a fresh cache installation. The error that I am getting right now is that gzip is required for a cache installation, but was not found in my system. Even though, this is shown as installed in the base centos 7 image. My host machine is Windows 10 using the latest docker version.

Here is my dockerfile, its simple:

Starting with 2017.1, InterSystems is adding Ubuntu (64-bit) as a third linux server platform. Prior to 2017.1 Ubuntu was already available as a development platform and customers could use InterSystems distributions build for SUSE to run on Ubuntu. As a result there are a few license key implications for 64-bit linux versions starting with Caché and Ensemble 2017.1:

a) Customers using RedHat will observe no changes

b) Customers using InterSystems products(1) for SUSE on SUSE will need new license keys (no charge)

Question Ivan Myasnikov · Mar 20, 2019

Good day.

Can you please tell me how to programmatically get a list of DFI files that have been uploaded to the IRIS server?

Since CacheStudio can do this, it means that you can perform this operation from the code.

For earlier, I thank all who are not indifferent to my problem.

I'm sure most of you have already familiar with the possibility of using GZIP in InterSystems products. But, the problem is that GZIP working only with one file or stream, and it does not support folders. When you work in Unix systems, there is a possibility how to solve it, using tar compress tool which goes with every Linux system from out of the box. But what to do if you have work on Windows as well, which does not have it. 

I am pleased to offer you my new project isc-tar, which will help you do not care about operating system, and deal with tar files anywhere.

I am just recently announced my project isc-tar. But sometimes it is not less interesting what’s behind the scene: how it was built, how it works and what happens around the project. Here is the story:

  • How to develop this project
  • How to test it
  • How to release new versions for publishing
  • And finally how to automate all above
  • Continuous integration

So, I would like to tell all about it.

I have a DR Mirror   with a WIJ that is 5 times as large as the Primary Failover member. My Read-Write Reporting mirror WIJs are the same size as the Primary.  I don't  know why the DR WIJ i so large and would like to shrink it to the same size as the others.  Any suggestions are welcome. Thanks!
