Hotel Overbooking in hospitality industry

This is the first InterStstems  programming contestthat we participated in! Come check out and vote for us!

The overbooking management system combines the unique conditions of the hotel, such as room prices, order channels, customer needs (etc.). System uses machine learning algorithms (such as: KNN/ES-RNN.

If you want to start IRIS as a service on CentOS7 you can use systemd.

Login as root and create a new file iris.service in /etc/systemd/system.

I'm participating in the Developing with InterSystems Objects and SQL with Joel Solon. The course is very nice and I will share with you some tips I got during the training. Tips presented in the day 3:

1. You can see your class catalog using %Dictionary classes and see your sql objects into INFORMATION_SCHEMA table.
2. Is possible use SQL inside your ObjectScript methods using Dynamic SQL or Embedded SQL.
3. You can pass parameters into Dynamic SQL string using ? (eg.: where country = ?) and pass parameters to Embedded SQL using colon (ed.: where country = :variable).

hello, I had build a DocDB referring the code from here: https://community.intersystems.com/post/how-can-i-create-properties-doc…

Here are the structure of the json Documents I have added in my database called 'Orders'.

InterSystems API Management (IAM) - a new feature of the InterSystems IRIS Data Platform, enables you to monitor, control and govern traffic to and from web-based APIs within your IT infrastructure. In case you missed it, here is the link to the announcement. And here's an article explaining how to start working with IAM.

In this article, we would use InterSystems API Management to Load Balance an API.

In our case, we have 2 InterSystems IRIS instances with /api/atelier REST API that we want to publish for our clients.

There are many different reasons why we might want to do that, such as:

• Load balancing to spread the workload across servers
• Blue-green deployment: we have two servers, one "prod", other "dev" and we might want to switch between them
• Canary deployment: we might publish the new version only on one server and move 1% of clients there
• High availability configuration
• etc.

Hi Community,

Hi Everyone!

I try to get the file size from an Archive in a SFTP service. The input is a %Stream.Object.

I'm trying to use input.Size or input.SizeGet() but i´ve got the next error:

Any suggestions?

Thanks in advance  =D

Hi Community!  Today I'd like to share with you a link to some exercises from a workshop about developing REST APIs and how to manage them using InterSystems API Manager.

It includes step by step exercises to:

• Developing REST APIs from OpenAPI specifications.
• Adding the created API in an interoperability production (optional).
• Basic API management in InterSystems API Manager (service, route, auth, consumers, rate limiting, etc.).
• Some other more complex scenarios in InterSystems API Manager like load balancing, or routing by header.

You will find it all here: https://openexchange.intersystems.

In the first installment of this article series, we discussed how to read a “big” chunk of data from the raw body of an HTTP POST method and save it to a database as a stream property of a  class. Now let’s look at how to save such data and metadata in JSON format.

Unfortunately, Advanced REST Client doesn’t let you compose JSON objects with binary data as a value of a key (or maybe I simply haven’t figured out how to do it), so I decided to write a simple client in ObjectScript to send data to the server.

I created a new class called RestTransfer.

InterSystems has identified an issue with product distributions containing Certificate Authority certificates that expire at the end of 2020. This issue does not affect system operation or system security in any way, although it does generate alerts about expiring certificates in the cconsole.log or messages.log files. The messages may be ignored and there are instructions below to eliminate them.

The issue affects the following versions:

• Caché and Ensemble 2017.1, 2017.2, and 2018.

Hi, 

I just published isc-mem-config on OpenExchange and ZPM. It's a prototype to test whether this kind of user experience (UX) is a good fit for novice and / or more seasoned users. The settings it generates are already fairly-good-practice :-), but also being reviewed by experts within InterSystems in parallel.

Happy to hear your feedback on the applicability to your and/or your customers' day-to-day business, where this would fit best in the broad spectrum ranging from documentation, over installation to standalone tools.

A question came up in the InterSystems developer community concerning the possibility of creating a TWAIN interface to a Caché application. There were several great suggestions on how to get data from an imaging device on a web client to a server, then store this data in a database. 

However, in order to implement any of these suggestions, you need to be able to transfer data from a web client to a database server and store the received data in a class property (or a table cell, as was the case in the question).

Hi I am new here. Please let me know where can I find posts related to using container registry. Thanks in advance!

Hey Developers,

Please welcome the new session recording from the InterSystems AI+ML Summit 2021:

⏯ AI+ML Summit Convergent Analytics – Cross-Industry Stream

When using "IDENTITY" as my primary key, I can select the last inserted ID with 

SELECT LAST_IDENTITY() FROM %TSQL_sys.snf;

Actually this is how Hibernate + Iris' Driver acquires the inserted ID when mapping with

@GeneratedValue(strategy = GenerationType.IDENTITY)

Now, considering that I am using the type "SERIAL" as my primary key instead, how can I get the last inserted ID?

Note that with "SERIAL" I can forcefully insert any value for this ID, from which Iris will continue generating values.

When I create a TASK on the Primary mirror member and Try to create the same TASK in the backup mirror member,  It Gives me CSP Application error.

The TASK gets created in the Primary node without any errors and When creating in the Backup node it prompts the error.

It happens is IRIS and I didn't face this in CACHE.

Finally what I did is export the TASK in Primary and Imported in Backup.

Is this a feature of IRIS?

想问一下IRIS里有SHA256withRSA  加密算法的实现吗？因为最近用到该加密算法进行接口调用。

Translated by moderator

I want to know if IRIS has SHA256 with RSA encryption algorithm? we have interface needing this encryption algorithm recently.

I have vendors asking for verification that messages for locations are coming through to them.  I can get generic ADT_A01 type of numbers in Activity.  I'd really like to get some good SQL queries that can give me a count of MSH.4s (for example) for a day for X Operation.  I'm not sure which table to look at for that information.

Hey Developers,

See how you can use InterSystems IRIS and Alteryx together to provide analytics and insights to your users.

Hello,

I have established an ODBC connection with our client based on credentials they provided.    The test connection was successful and after using the Link Table wizard I can now see the client's tables and properties.    However when we try to execute a query in IRIS we are getting error code -226.   I'm trying to determine if this could be just a simple setting problem in IRIS or something with the client.   

We have tried with PostgreSQL as well as with TSQL.  Same result for each.

Has anyone seen this error before and could it be pointing me in a certain direction?

Hi everyone, I am trying to return a cloned version of my ADT that I have made changes to in a Business Process.  So far I have the following in my process.  

&sql(Select MemberId INTO :pMemberIDval from CDSM_MemberAPI.MemberInfo where MemDOB = :ptDOB and MemLname = :ptLname and MemFname = :ptFname)

set newrequest = pRequest.%ConstructClone()

set MemberIDPID4 = newrequest.SetValueAt(pMemberIDval, "PID:4.1")

The following does return the value I am populating the clone with to the log

  set newrequestPID4 = newrequest.GetValueAt("PID:4.

Hi developers!

Recently we announced the preview of Embedded Python technology in InterSystems IRIS.

Check the Sneak Peak video by @Robert.Kuszewski.

Embedded python gives the option to load and run python code in the InterSystems IRIS server. You can either use library modules from Python pip, like numpy, pandas, etc, or you can write your own python modules in the form of standalone py files.

So once you are happy with the development phase of the IRIS Embedded Python solution there is another very important question of how the solution could be deployed.

One of the options you can consider is using the ZPM Package manager which is described in this article.

Hi Developers!
