Hi, I have used CSP to exec SQL selects from  any own NAMESPACE. But in our servers we have many SQL GATEWAY CONNECTIONS.

I'd like to create a CSP page that could use these gateway to exec SQL using these gateway connections, only Administrators will use that page to launch many select at many dsn. I'm not sure if we must deploy that CSP on %SYS namespace and how to use DSN(SQL Gateway connections) that are defined on server.

Anoyone has made that?

For example:

DSN CLIENT ONE

DSN CLIENT ONE

 

CSP Webpage:

TEXTBOX: Introduce your select:

select count(*) from product where stock<100 

OPTION BUTTON:

*CLIENT ONE

*CLIENT TWO

 

Result:

Product One.

Product Two.

Product Five...

InterSystems Caché globals provide very convenient features for developers. But why are globals so fast and efficient?

Theory

Basically, the Caché database is a catalog having the same name as the database and containing the CACHE.DAT file. On Unix systems, the database can also be an ordinary disk partition

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.

InterSystems Data Platform includes utilities and tools for system monitoring and alerting, however System Administrators new to solutions built on the InterSystems Data Platform (a.k.a Caché) need to know where to start and what to configure.

This guide shows the path to a minimum monitoring and alerting solution using references from online documentation and developer community posts to show you how to enable and configure the following;

  1. Caché Monitor: Scans the console log and sends emails alerts.

  2. System Monitor: Monitors system status and resources, generating notifications (alerts and warnings) based on fixed parameters and also tracks overall system health.

  3. Health Monitor: Samples key system and user-defined metrics and compares them to user-configurable parameters and established normal values, generating notifications when samples exceed applicable or learned thresholds.

  4. History Monitor: Maintains a historical database of performance and system usage metrics.

  5. pButtons: Operating system and Caché metrics collection scheduled daily.

Remember this guide is a minimum configuration, the included tools are flexible and extensible so more functionality is available when needed. This guide skips through the documentation to get you up and going. You will need to dive deeper into the documentation to get the most out of the monitoring tools, in the meantime, think of this as a set of cheat sheets to get up and running.

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.

Greetings, InterSystems community!

I am pleased to announce that the web terminal project, Caché WebTerminal version 4 gets its release! After long period of enhancing this web application from 2013, it came to the version 4, which features major stability and security improvements, intelligent autocomplete and syntax highlighting, convenient SQL mode and a lot of other useful features.

The goal of this article is to spread the knowledge about this project over the InterSystems community.

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?

This is on:     Cache for Windows (x86-64) 2017.1.1 (Build 111_0_17521U) Wed Jul 26 2017 13:08:05 EDT [HealthShare Modules:Core:15.03.8382 + Linkage Engine:15.03.8382 + Patient Index:15.03.8382 + Clinical Viewer:15.03.8382 + Active Analytics:15.03.8382]

The Amazon Web Services (AWS) Cloud provides a broad set of infrastructure services, such as compute resources, storage options, and networking that are delivered as a utility: on-demand, available in seconds, with pay-as-you-go pricing. New services can be provisioned quickly, without upfront capital expense. This allows enterprises, start-ups, small and medium-sized businesses, and customers in the public sector to access the building blocks they need to respond quickly to changing business requirements.

Hi, a client have a installed enviroment with mirror activated, but when you test SSL on webservices you can get an error, not SSL access correctly from browser because certificate problem apparently with TLS Version, someone have a suggestion to reinstall SSL Certificates on mirrors ?

Chrome : something wrong, no details or diagnostic
Firefox : SSL_ERROR_HANDSHAKE_FAILURE_ALERT

We try simple regenerate Authority an regenerate all certificates, but not worked. Same results.

Hey Developer Community,

I wanted to reach out and ask the group who is still using the Polymetric Dashboard? You can read about it in this older Community article.

It was created as a sample that is designed to be customized by you, so it is a community supported tool vs. an official InterSystems supported tool.  I've noticed that it hasn't been updated in a while and some of the dependencies have some potential security vulnerabilities.  If you are using the tool internally, it isn't an issue, but was wondering if anybody who is using it has already updated their code with newer dependencies, etc?

So, is there interest from the community in updating it?  Or testing it with IRIS?

There are often questions surrounding the ideal Apache HTTPD Web Server configuration for HealthShare.  The contents of this article will outline the initial recommended web server configuration for any HealthShare product. 

As a starting point, Apache HTTPD version 2.4.x (64-bit) is recommended.  Earlier versions such as 2.2.x are available, however version 2.2 is not recommended for performance and scalability of HealthShare.

Can someone tell me if /deepsee-sysmon-dashboards is developed for a specific version of Ensemble? Looks like it could be useful to my group but we aren't upgrading till later this year and we are on 2015.2.2.

Thanks

We are currently using Ensemble on AIX. We are on 2015.2.2. If I install Field Test on a windows desktop, is it possible that I can import the Cache.dat from my AIX server, so I can do some Proof of Concept development?

Thanks

InterSystems products (IRIS, Caché, Ensemble) already include a built-in Apache web server. But the built-in server is designed for the development and administration tasks and thus has certain limitations. Though you may find some useful workarounds for these limitations, the more common approach is to deploy a full-scale web server for your production environment. This article describes how to set up Apache to work with InterSystems products and how to provide HTTPS access. We will be using Ubuntu, but the configuration process is almost the same for all Linux distributions.

This article was written as an attempt to share the experience of installing the InterSystems Caché DBMS for production environment.
We all know that the development configuration of a DBMS is very different from real-life conditions.
As a rule, development is carried out in “hothouse conditions” with a bare minimum of security measures, but when we publish our project online, we must ensure its reliable and uninterrupted operation in a very aggressive environment.

The process of installing the InterSystems Caché DBMS with maximum security settings

OS security settings

The first step is the operating system. You need to do the following:

Let's say you have about 100TB of data in multiple CACHE.DAT. The biggest one is about 30TB but mostly more than 1TB. You have limited time for maintenance during a day, and it is only a few hours at night. You have to check Integrity as much often as possible. And of course backup it.

How would you do it?

Everybody has a testing environment.

Some people are lucky enough to have a totally separate environment to run production in.

We are trying to script a High Availability Shutdown/Start script in case we need to fail over to one of our other servers we can be back up within mins. Is there a way to configure the startup procedure to Automatically Stop/Start the JDBC server when shutting down or starting up cache? is there an auto setting we can change?

Thanks

In this post I show strategies for backing up Caché using External Backup with examples of integrating with snapshot based solutions. The majority of solutions I see today are deployed on Linux on VMware so a lot of the post shows how solutions integrate VMware snapshot technology as examples.

Caché backup - batteries included?

Caché online backup is included out of the box with a Caché install for uninterrupted backup of Caché databases. But there are more efficient backup solutions you should consider as systems scale up. External Backup integrated with snapshot technologies is the recommended solution for backing up systems including Caché databases.

Are there any special considerations for external backup?

Online documentation for External Backup has all the details. A key consideration is

Containers

With the launch of InterSystems IRIS Data Platform, we provide our product even  in a Docker container. But what is a container?

The fundamental container definition is that of a sandbox for a process.  

Containers are software-defined packages that have some similarities to virtual machines (VM) like for example they can be executed. 

Containers provide isolation without a full OS emulation. Containers are therefore much lighter than a VM. 

In their essence, containers are an answer to the issue of how to reliably move an application from a system to another and guarantee that it will work. By encapsulating all application dependencies inside a container and creating a process isolation space, there is a higher degree of guarantee that the application solution will run when moved between platforms.

Hi

Totally new to IRIS and Cache.

Trying to evaluate it and work out how we could use it.

As a standard application database. Object or relational etc. does not matter. 

Issue is ObjectScript.

So:

1) Can we develop, maintain and use an IRIS database and never use ObjectScript i.e. use only Java, Python, C++ interfaces etc. (exactly which one does not matter)? Would that make designing and using the IRIS database more prone to inefficiency and error?

2) Can we import an existing Cache database into IRIS and convert its ObjectScript code into Java, Python whatever? Is that a big, difficult, error-prone job?

If the answers are no that may not be a showstopper but would like to know it now. 

A lot of training will be involved in any case I know and Oracle has PL/SQL but ObjectScript developers are rare.

Apologies if the answers are in the doco. Have read some of it but need some indication about the above urgently.

I need to write a script to answer a couple of fairly simple questions:

1) What is the current routine DB (name and location) for this namespace?

2) What is the current data DB (name and location) for this namespace?

3) Is global ^ABC mapped to a different location than the default data DB?

Can anyone point me to some system APIs that would allow me to answer these questions?

Thanks!

Ben

Continuing on with providing some examples of various storage technologies and their performance profiles, this time we looked at the growing trend of leveraging internal commodity-based server storage, specifically the new HPE Cloudline 3150 Gen10 AMD processor-based single socket servers with two 3.2TB Samsung  PM1725a NVMe drives.

All,

Recently, a Cache 2017.2.2  system started printing “28”  rather than clearing the screen when doing a  “W #”  in programmer mode.

Does anyone have any idea how this could happen?

This should clear the screen, but doesn't:

XXXX:YYYY>W #
28

Google Cloud Platform (GCP) provides a feature rich environment for Infrastructure-as-a-Service (IaaS) as a cloud offering fully capable of supporting all of InterSystems products including the latest InterSystems IRIS Data Platform. Care must be taken, as with any platform or deployment model, to ensure all aspects of an environment are considered such as performance, availability, operations, and management procedures.  Specifics of each of those areas will be covered in this article.

September 24, 2018 – Advisory: VMWare vSAN and Data Integrity

Clients running vSAN 6.6 or later should review a very important article that VMware published on September 21, 2018.  The article describes the possibility of file system and database corruption, which can lead to outages and possible data loss, and we believe that some of our clients have encountered this issue.  Therefore, we encourage you to act on this as soon as possible.

The VMWare knowledge base article is titled:

Virtual Machines running on VMware vSAN 6.6 and later report guest data consistency concerns following a disk extend operation (58715)
