#Databases

Hi Community,

What is the correct syntax in a merge.cpf file to create a database with its associated resource ?

Hi experts

I'm trying to configure an IRIS ODBC connection with "Windows NT authentication using the network login ID". I have created the System DSN as below:

and user (PROD\test) in the SQL Gateway connection 

However, as the error message suggests, IRIS is trying to connect with PROD\svc_mist, rather than PROD\test configured above. 

Is there anyway to configure the ODBC connection with specified account with Windows Auth method? 

Hi Team, 

Can I please check if anyone has built a simple web interface for maintaining custom SQL lookup class.  

We have a simple persistent class in HealthShare which is used for storing Pathology test codes. Test codes in this lookup class is used for message filtering and applying additional logic when processing pathology results/orders. 

We want to make this class available to external users from pathology (not the usual management portal users) to maintain so that they can add/edit/delete test codes as required.

At the moment, we have 10 HealthShare instance servers (5 x mirrored pairs), where we implement an External Backup approach, using the freeze/thaw commands against whichever server of the pair is the backup mirror member, to complete a VM level backup. These backups are stored to a disk within our control, to purge as required. This approach allows us to deliver a zero downtime backup approach.

I am working on a tool that configures an instance to use a common default routine database across all custom Namespaces. For instances that already have distinct default routine databases for their Namespaces, this would involve a step of merging over all code from the current default routine databases to the new "super" routine database. This should be done in such a way that only merges contents in the default routine database (not mapped databases) and is able to detect/exclude contents that already exist in the target database.

I would like to learn about the binary and document reference FHIR Resources. For the PDF data stored in those resources. But I think Binary Resource for the Document PDF stored in FHIR, so this resource is best for it. So sometimes Large PDF 15-page (~35md) data converts into base64 then data length is ~50 lac charecters length of base64binary data. this data store in Binary Resource on data field https://www.hl7.org/fhir/R4/binary.html follow this url this resource used in my case. so it's support the 50 lac charecter of the base64 length? This resource can be Insert into IRIS?

We currently have Business Operation that we built to use the EnsLib.SQL.OutboundAdapter so we can make Microsoft SQL Server Stored Procedure calls. The BO is attached to a Java Gateway Service.

Some of our MS SQL Databases have moved from being OnPrem to Azure Cloud. We have started seeing where we are receiving errors on the BO saying that we cannot connect to the Azure Database, but we never receive a Disconnect from the Azure Database.

Hi, I'm wondering what are the diferences between a method or classmethod with the language set at tsql and a querry writen in sql.
If anyone know if there is some difference and what they are, I would be glad to learn. 😊

We’re building out a data lake in IRIS 2025.1 that aggregates data across multiple business systems and departments. I’m trying to establish best practices for schema design and separation.

Right now, I’m thinking of using a separate schema for each distinct system of record feeding into the data lake - for example, one schema per upstream source system, rather than splitting based on function (e.g. staging, raw, curated). The idea is that this would make it easier to manage source ownership, auditing, and pipeline logic, especially when multiple domains are contributing data.

Hello my friends,

I have a problem with logi report, 

in my store procedure,  I create code like this?

$ListToString(%DLIST(DISTINCT (ARCIM_Desc)),'<br/>') as "ARCIM_Desc", -> this is the problem

$ListToString(%DLIST(DISTINCT (MRDIA_ICDCode_DR)),'<br/>') as "MRDIA_ICDCode_DR", -> it's works fine

as you see there's a <br/> in the display of the report

I have no idea about this, maybe someone can help me fix this problem ?

Thank You

Best Regards,

Hello my friends,

I have a problem with Objectscript, why the value of address become like this ?

everything works fine except the Address,

this is my code, do I need something to make this into real address ? should I put something in my code ? 

 set paper=obj.PAADMPAPMIDR.PAPMIPAPERDR

            if '$isobject(paper) continue

            set Address=paper.PAPERStName

thank you for your help

I have notified that on several servers the IRISTEMP database is reported as only a few GB in size while on the disk where it's located, the IRIS.DAT file is much bigger (eg: 3GB reported in Portal (including free space) while file on the disk file is 121GB). The last modification date of IRIS.DAT is recent so I'm not looking into a location no more in use.

Is there an explanation for that difference in size ? 

I know temporary databases are special in a way they are not always stored on the disk, here is what InterSystems says about it :

Changes to temporary globals are not written to disk.

I have a database that is 2TB in size (from a LIVE system).

I would like to defragment it but I have some questions. I took a look at official documentation but it does not help.

• Is is possible to get a measurement about how much database is fragmented ? (eg: a percentage). Most operating systems are able to give a an indication about how much a filesystem is fragmented before any operation.
• The database is on a LIVE server, the IRIS service is restarted every night (around 1AM). Because of that I can't run defragment continuously. I don't think it will be able to complete under 24 hours.

Hello,
I have created this script that does lot of writes to a single global. DB write performance is much slower than expected (compared to another similar systems).

set"..."//fill it with something

I have notified the following : 

• CPU usage does not reach 100% on a single core (eg: 25% of total CPU usage should be seen on a 4 cores system). Instead, much lower CPU usage is shown (with some drops to 0% from time to time). It looks like process has to wait for I/O completion before proceeding. Removing the set

I have created a New Database/Namespace within our TEST environment on both the Primary and Backup of the mirror. When I go to create the database/namespace on the DR node I am getting "Cannot open file '/ensemble/TEST/iris.cpf_...." while the cpf file that it references does not exist. Anyone have any clue to why this might be happening?

Hi,

     Can anyone please tell me how to append a string using a update query.

For eg :  "Hello" is the string . I need to append the string world and it needs to be "Hello world".

Thanks

Hello,

Our software commonly returns a full result set to the client and we use the DataTables plugin to display table data.  This has worked well, but at datasets grow larger, we are trying to move some of these requests server-side so the server handles the bulk of the work rather than the client.  This has had me scratching my head in so many ways.  

I'm hoping I can get a mix of general best practice advice but also maybe some IRIS specific ideas.

Hello everyone,

I’m facing issues with replicating data from my Caché 2016 database to a PostgreSQL database. I need to handle around 300 data updates per minute, and whenever certain tables are modified, those changes must be reflected in other databases.

So far, I’ve tried various approaches, including:

• Setting up an intermediary API,
• Using Azure Service Bus,
• Leveraging Caché Jobs,
• All of which rely on table triggers as the entry point.

However, each of these solutions has led to performance bottlenecks and system lockups.

Hello, community.

I have a problem with running a SQL query on a linked MySQL table.

The connection works fine, but the following query throws an error:

SELECT   TOP 10 * FROM   linkedinternal_test.persons

 [SQLCODE: <-400>:<Fatal error occurred>]

  [%msg: <Remote JDBC error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '10 T1.PersonID AS C1,T1.LastName AS C2,T1.FirstName AS C3,T1.Address AS C4,T1.Ci' at line 1. >]

Linked table class:

/// Generated by the Link Table wizard on 2025-01-08 16:09:03.  Note that you can access the data in this class only when the external database is accessible.

I need to see the full SMTP trace when a %Net.SMTP attempts to send an email to troubleshoot an issue. As far as I know, the only way to get that is to uncomment line 192 in the %Net.SMTP class.

 //:#define SMTPTRACE

I've done this in the past by giving myself the %DB_IRISSYS role, so I tried that. That database is also not mounted as read-only.

Of course the bigger issue here is that I can't seem to get that trace without having to edit a system class or create my own, but to fix my more immediate issue, what else do I need to check that would be preventing me from editing that class?

Hi everyone,

I'm trying to connect my Laravel application with the InterSystems IRIS Data Platform using ODBC.I need help setting up the ODBC connection and querying the database properly. What is the proper way to configure Laravel to work with an ODBC connection to InterSystems IRIS?

Any help would be greatly appreciated!

Thanks in advance!

Hi!

Suppose I have full access to InterSystems IRIS database instance A and want to export a consistent part of the data and import it into another InterSystems IRIS instance B. Classes are equal.

What are the most general and convenient options for me?

TIA!

Every time I try to update an SQL table using odbc connection, I'm getting: ERROR <Ens>ErrException: <MAX $ZF STRING>zPrepareW+1^%Library.SQLGatewayConnection.1

Set sqlStatement = "UPDATE dbo.Table1 SET OriginalMessageText="_OriginalMessageText_"WHERE Id='"_Id_"'"
$$$TRACE("SQL Statement: "_sqlStatement)

I know that the problem is with the length of the ORU HL7 message  (that contains OBX base64 PDF file ) I'm trying to update in the table, but is there a way to fix this? other than truncating the message ?

I also tried this statement but it didn't work as well

Set sql = "UPDATE dbo.

I need to do an audit of Linked tables which are using a specific SQL Gateway connection, and there are many.

This is defined by the parameter CONNECTION contained within the table class which extends Extends %Library.Persistent

Is parameter exposed within a table somewhere?

Hello all,

We have our system with AutoParallel enabled:

USER>w ##class(%SYSTEM.SQL.Util).GetOption("AutoParallel")
1

But whenever I try to run any sql the autoparallel does not work. For example, this simple query:

When I force it with %PARALLEL we can see it will effectively run in parallel:

The total records is bigger than the threshold. So, what can go wrong? Anyone in the same situation?

Hi! I am trying to export Cache data to my SQL database and am trying to export the schema as well.

The Data Export wizard on the Management Portal only allows me to export the data but not the schema. Is there anyway to get the schema exported as well?

Hi all.

I hope you can help me.

I've renamed a namespace and its databases names.

• Old Namespace: LABORATORIO
• New namespace: SRV-LABORATORIO

The rename of all has worked fine. When I've tried to access to the portal, it is no available, displaying the message "Tha namespace SRV-LABORATORIO does not support productions"

So, I've run the following command in terminal

zn"SRV-LABORATORIO"do

My IRIS has created the links to create the production.

Now, I've opened the portal but my code has disappear.

I have an IRIS installation that is using 8-bit charset encoding (set to deu8 / Latin 1). I would like to convert everything (database and system) to Unicode

Charset encoding is something asked during installation, is it possible to change this on the fly ? The installer clearly say that Unicode systems cannot be converted. What about 8 bit ? 

Same for database : is there possible conversion ?

My current plan is the following :

- export all globals from 8-bit instance
- install a new Unicode instance
- import all globals into Unicode instance

Is there a simpler approach ?

Hi Community!

Suppose you have a working system on 8-bit Caché database and need to transfer the solution to Unicode database.

How do you manage that?
