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:

FROM centos:latest

RUN yum update -y && yum -y upgrade

COPY ./cache-2017.1.3.317.0.18571-lnxrhx64.tar.gz .

RUN tar -zxf cache-2017.1.3.317.0.18571-lnxrhx64.tar.gz

RUN ISC_PACKAGE_INSTANCENAME="MyDatabase" \

          ISC_PACKAGE_INSTALLDIR="/usr/cachesys/" \

          ISC_PACKAGE_UNICODE="Y" \

         ISC_PACKAGE_CLIENT_COMPONENTS="" \

         ISC_PACKAGE_INITIAL_SECURITY="Minimal" \

        /cache-2017.1.3.317.0.18571-lnxrhx64/cinstall_silent



EXPOSE 57772 22 1972

ENTRYPOINT ["ccontrol", "start cache"]

Hi! We have received a request to create a new rule on CachéQuality to identify when a developer uses double quotes (" ") within any SQL statement.

We have been asked many times about SQL validation rules, and we would like to open a debate to allow everyone discuss what would you like to be checked on a SQL statement.

Current examples are for basic situations:

  • Using SQL.Statement class:

Set stmt = ##CLASS(%SQL.Statement).%New()
Set query = "Select Val1, Val2 FROM Table WHERE Val1=""SomeCondition"""

  • Using embedded SQL

&SQL(SELECT Val1, Val2
                INTO :val1, :val2
                FROM Table
                WHERE Val1="SomeCondition")

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)

c) Customers using InterSystems products(1) for SUSE on Ubuntu will need new license keys (free of charge for 12 month(2))

(1) Caché, Ensemble, HealthShare, and TrakCare

(2) Starting with the Release of 2017.1

Hi Community!

I think everyone keeps the source code of the project in the repository nowadays: Github, GitLab, bitbucket, etc. Same for InterSystems IRIS projects  check any on Open Exchange.

What do we do every time when start or continue working with a certain repository with InterSystems Data Platform?

We need a local InterSystems IRIS machine, have the environment for the project set up and the source code imported.

So every developer performs the following:

  1. Check out the code from repo
  2. Install/Run local IRIS installation
  3. Create a new namespace/database for a project
  4. Import the code into this new namespace
  5. Setup all the rest environment
  6. Start/continue coding the project 

If you dockerize your repository this steps line could be shortened to this 3 steps:

  1. Check out the code from repo
  2. Run docker-compose build 
  3. Start/continue coding the project 

Profit - no any hands-on for 3-4-5 steps which could take minutes and bring head ache sometime.

You can dockerize (almost) any your InterSystems repo with a few following steps. Let’s go!

This question is about calling AWS REST APIs. Based on:

http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html

AWS requires REST clients to call their APIs using Signature Version 4 which in case you don't know what I am talking about is a pain in the neck.  Here comes the question:

Has anybody, by any chance implemented the v4 signing alg. in COS? If yes, would she or he have the kind heart to share?

Thanks,

Chris

InterSystems states that Caché supports at least three data models – relational, object and hierarchical (globals). On can work with data presented in relational model in a program written on C# the same way one works with any other relational DB. To work with data presented by object model in C# one needs to use .NET Managed Provider or some kind or ORM. And starting with version 2012.2 one can work directly with globals (or use direct access to hierarchical data) via Caché eXTreme for .NET.

I'm attempting to use the .NET Entity Framework provider that is provided by InterSystems (see: https://docs.intersystems.com/latest/csp/docbook/DocBook.UI.Page.cls?KEY=GBMP_eframe).  In our environment, the "Support Delimited Identifiers" option is turned off and we are not allowed to turn it on without significant testing effort.  When this setting is off, the SQL that is generated by the Entity Framework provider is not considered valid and therefore the provider doesn't work (it DOES work, however, when this setting is turned ON).

Do you know of any way to work around this issue? Again, we don't have the option of turning the "Support Delimited Identifiers" option ON unfortunately.

Is it possible to mimic what selenium does like navigating to a site and logging in  and filling out a form then logout in COS.I am trying to do that in COS using %Net.HttpRequest class or should I be using a different class the idea is to be able to call a web app login into it and fill out form and log out

Database systems have very specific backup requirements that in enterprise deployments require forethought and planning. For database systems, the operational goal of a backup solution is to create a copy of the data in a state that is equivalent to when application is shut down gracefully.  Application consistent backups meet these requirements and Caché provides a set of APIs that facilitate the integration with external solutions to achieve this level of backup consistency.

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.

Hello,

 

Last weekend we've updated our Caché version to 

Versie:Cache for Windows (x86-64) 2018.1.1 (Build 312U) 

 

I'm using Studio to develop. I've been using the built-in debugger and it has been working nicely. But now, since the upgrade, I'm getting this error when trying to debug any routine or class method:

Executing ##class(Blue.App.Handler.Adsolut).TestConnection()
<COMMAND>zDebugStub+30^%Debugger.System.1

 

This is the code for the classmethod I got the error on

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!

Keywords:   Jupyter Notebook, Tensorflow GPU, Keras, Deep Learning, MLP,  and HealthShare    

 

1. Purpose and Objectives

In  previous"Part I" we have set up a deep learning demo environment. In this "Part II" we will test what we could do with it.

Many people at my age had started with the classic MLP (Multi-Layer Perceptron) model. It is intuitive hence conceptually easier to start with.

So let's try a Keras "deep learning MLP" with standard demo data that everybody in AI/NN community has been using. It is a kind of so called "supervised learning". We will see how simple to run it on the Keras level.

We could later touch on its history and on why it's called "deep learning" the buzz word - what actually evolved over the recent 20 years.Â

Hi -

I'm having odd behaviors on my EC2 hosted IRIS Community instance.

When I configure a "custom login page" in the System Management Portal for my web application I'm seeing a few different behaviors that are under documented (and also undesired)

The old Caché documentation indicates that the custom login page could be a ".csp" file, but this seems to nor be the case (i kept getting "not found" errors, even though I could bring up the page directly from the url FOR the login.csp file. To get around this, I created an HTML file and then, at least, the login page could be found to be rendered

In recent discussion on CachéQuality I was (friendly) blamed for old syntax promotion and deliberate obfuscation of the code. Therefore I decided to clarify my point and shed some light on one of possible source of side effects that may unexpectedly occur with RETURN command with an argument.

Keywords:  Anaconda, Jupyter Notebook, Tensorflow GPU, Deep Learning,  Python 3 and HealthShare    

1. Purpose and Objectives

This "Part I" is a quick record on how to set up a "simple" but popular deep learning demo environment step-by-step with a Python 3 binding to a HealthShare 2017.2.1 instance .  I used a Win10 laptop at hand, but the approach works the same on MacOS and Linux.

Last week it was noticed that Python overtook Java by becoming the most popular language in PYPL Index.  Tensorflow is a powerful computation engine, which is very popular in research and academic worlds too. HealthShare is a data platform that provides an unified care record of patients for care providers

Hello everyone smiley

I have a server configuration in a CSP Gateway installed on a PC (let's call it S2) different from the main one (let's call it S1). This configuration allows me to access a web application that is installed on S1, from a client C asking S2 for this webapp. But for now it works only in HTTP between C and S2, and we would like to use HTTPS (as it already works between S2 and S1).

First here are the tutos found in the doc:
