Could any one tell me, how the index works in cache db, Consider for example, I have a table called "Employee" and the fields as "EMPID, EMPNAME, EMPAGE" and I am having index for EMPID as IDX_EMPID and trying to get the record using the following query as

SELECT * FROM EMPLOYEE WHERE EMPID="005"

and the table data be like

EMPID EMPNAME EMPAGE

001 ABC 20

002 AAA 21

003 ABB 23

004 BBB 20

005 BDF 24

006 EEE 22

If you want to run an OS executable file, command, or a program created within an InterSystems product when the InterSystems product starts, write the processing in the SYSTEM^%ZSTART routine. (The %ZSTART routine is created in the %SYS namespace).

Before you write any code in SYSTEM^%ZSTART, make sure that it works properly under all conditions.

Hi All,

I'm trying to connect to an IRIS instance using VSCode, the problem is, there are 2 IRIS instances installed on this server, published by the same hostname using https (port 443) under 2 different subfolders (e.g., iris.demo.com/base & iris.demo.com/test).

When connecting via studio, I was able to connect by using the hostname (e.g., iris.demo.com) and specifying the super server port, while when connecting through VSCode, when specifying the web server port 443, the connection is always defaulted to one of the instance.

Hi Community,

In this article, I will introduce my application iris-HL7v2Gen .

IRIS-HL7v2Gen is a CSP application that facilitates the dynamic generation of HL7 test messages. This process is essential for testing, debugging, and integrating healthcare data systems. The application allows users to generate a wide variety of HL7 message types, validate their structure against HL7 specifications, explore the message hierarchy, and transmit messages over TCP/IP to production systems. These features are particularly useful in settings where compliance with HL7 standards is mandatory for interoperability between different healthcare organizations or systems.


Application Features

  • Dynamic HL7 Message Generation: Instantly create HL7 messages for a range of message types, facilitating comprehensive testing.
  • Message Structure Exploration: Visualize the structure of generated messages based on HL7 specifications.
  • Value Set Visualization View predefined sets of allowable coded values for specific fields.
  • Message Validation: Validate messages against HL7 standards to ensure compliance.
  • TCP/IP Communication: Easily transmit messages to production using TCP/IP settings.
  • Broad Message Type Support: Supports 184 different HL7 message types, ensuring versatility for various healthcare integration needs.
  • ClassMethod: Generate a Test Message by Invoking a Class Method
  • Version Support: Currently Supports HL7 Version 2.5

Hello,

While doing research on the upgrade to InterSystems IRIS 2024.1.2 version, I was wondering if it would be possible to rollback the installation and return to the previous version in case something went wrong ?

I didn't see anything talking about this in the documentation and when I tried to re-install an older kit over an upgraded instance, I couldn't use it.

Thank you in advance for your reponse

Hello Community,

I have below issue -

I have an ID with 123456.(ID as a dynamic value coming from request message)

I wanted it to be displayed as "123456" in Json Stream.

Code Example:

set object = ##class(%ZEN.proxyObject).%New()

set object.ID = ID

set x = ##class(%ZEN.Auxiliary.jsonArrayProvider).%WriteJSONStreamFromObject(.json,object)

Case:1
ID : 123456

Will output:

{

"ID": 123456

}

but I need :

{

"ID": "123456"

}

HL7 Encoding issue

Dear All,

I have been sent an HL7 message as a file with the MSH segment as follows....

MSH|^~\&|SendingApp|pms3medd|HealthLink|cribrumt|20241121050000|PKI|ORU^R01|01_ASCIItest_2|P|2.3.1||||||UNICODE

I try picking up the file with a "EnsLib.HL7.Service.FileService" business service using a EnsLib.File.InboundAdapter adaptor. The Character set is set to "Native" and the Default Char Encoding to latin 1.

I am seeing the following error:

So if you are following from the previous post or dropping in now, let's segway to the world of eBPF applications and take a look at Parca, which builds on our brief investigation of performance bottlenecks using eBPF, but puts a killer app on top of your cluster to monitor all your iris workloads, continually, cluster wide!

Hi all,

I have some .vm (Velocity Templating Language) files that I'd like to be able to load into IRIS with the $System.OBJ.Load(filename) command, but it seems that only accepts XML files.

I've tried adding import/export logic in my custom studio document that will wrap the velocity content inside an XML document and vice versa, I've changed the existing Velocity files to have the extension .xml and be wrapped in XML, and I've included a .dtd file for them to reference. However, this doesn't seem to work.

Hi

Is there a way to generate an MD5 checksum of a file by performing a checksum against the file's parts? We potentially have to process large files and therefore cannot keep the entire file in memory. From what I understand checksum related logic is typically stateful, allowing file data to be passed through sequentially, however it appears cache script offers only stateless functions offering a simple method of generating a single checksum hash from a single string (or stream), correct me if I'm wrong?

The "Ask Developer Community AI" tool is an excellent resource for studying for the certification. I asked it about each topic that will be covered in the test and the results are below.
Note: I classified each answer by the assertiveness that I consider as good, average and bad.

Note 2: The article has 4 parts, each one for an exam area.
