How InterSystems solutions handle C10k connections? ( https://en.wikipedia.org/wiki/C10k_problem )
For example, I want to create a social network on InterSystems platform.
In the scenario client (browser) => CSP Gateway => Cache can the Cache handle a large number of clients at the same time?
Quick analysis shows that CSP Gateway for each request opens a new TCP connection to Cache SuperServer (port 1972) allocating CSP session and license slot.

Dear Community,

I need to collect a file from an FTP server over FTPS.

I have the :

• credentials saved correctly
• correct host and port informatoin
• correct filepath I am trying to collect from
• I have setup the SSL configuration in System > Security Management > SSL/TLS Configurations and this tests sucessfully

When I run the business service to connect it connects, but soon after connecting it fails to open the directory:

As we all well know, InterSystems IRIS has an extensive range of tools for improving the scalability of application systems. In particular, much has been done to facilitate the parallel processing of data, including the use of parallelism in SQL query processing and the most attention-grabbing feature of IRIS: sharding. However, many mature developments that started back in Caché and have been carried over into IRIS actively use the multi-model features of this DBMS, which are understood as allowing the coexistence of different data models within a single database. For example, the HIS qMS database contains both semantic relational (electronic medical records) as well as traditional relational (interaction with PACS) and hierarchical data models (laboratory data and integration with other systems). Most of the listed models are implemented using SP.ARM's qWORD tool (a mini-DBMS that is based on direct access to globals). Therefore, unfortunately, it is not possible to use the new capabilities of parallel query processing for scaling, since these queries do not use IRIS SQL access.

Meanwhile, as the size of the database grows, most of the problems inherent to large relational databases become right for non-relational ones. So, this is a major reason why we are interested in parallel data processing as one of the tools that can be used for scaling.

In this article, I would like to discuss those aspects of parallel data processing that I have been dealing with over the years when solving tasks that are rarely mentioned in discussions of Big Data. I am going to be focusing on the technological transformation of databases, or, rather, technologies for transforming databases.

We have some code written by earlier team that read flat files data and create SDAs and push them to ECR Input Service. Now for every test cycle we have to load files to SDAs, check error log, fix the error, clear the ECR, and try new fixed flat files. I’d like to know if there is a method to validate SDA msgs prior to pushing to EFR Input operations ?

so everything we simple load flat files, create SDAs and validate them. If files all looks good with no SDA errros then we actually load them to ECR only once.

Hi,

Hello!

How to set null in variable?

Hi Developers!

Want to raise security discussion today!

Let's discuss how InterSystems security for applications works. In general, the concept is clear: we have Resources (what to protect), Roles which combine a set of privileges and accesses to Resources and Users which can have this or that Role.

But there is also a concept of Application which also could have a Role.

So you either provide a Role for a User or for an Application.

What do you use in production? What is your strategy and why? Pros, cons?

Hi community!

Is it possible generate HTML documentation to my project ObjectScript classes (.cls)?

In Java we use Javadoc to do it. Javadoc get class comments and java metadata information and when I execute javadoc -d doc src\*, I get whole html documentation to my classes. Has IRIS something like javadoc? Is it documatic? If yes, how can I use it?

Hi,

I'm trying to access the categories configuration for the WorkMgr via COS, so I can be able to create new categories for our processes and this way try to overlock the limit of cores*2 workers. I've seen that last version of IRIS is supposed to have a menu on the portal (System Administration > Configuration > System Configuration > WQM Categories), but since we are in 2020.1 this doesn't exist.

Does anyone have experience with WQM.API to manage the categories, or the usage of ^%SYS("WQM") to set it directly?

Hi Developers,

Watch the new video on InterSystems Developers YouTube to learn how to develop with InterSystems ObjectScript using the Visual Studio Code plug-in.

Hi,

I need to develop a HL7 Q22/K22 query/response mechanism for a NHS Trust I am working for, but I do not know how to handle the message continuation.

Can any one give me any advise on this and/or point me in the direction of any documentation on the subject?

Thanks

Neil Thaiss
