InterSystems Caché database is a file where all the data, application scripts, and users, roles and security configurations are stored. Typically the name of the file is cache.dat.
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).
Hello! In this article, I will be discussing database degrade, a type of data integrity issue one can face when using IRIS. First, I will be going over a review of the structure of IRIS databases. I'll then discuss how database degrade can manifest and common causes of degrade issues. I'll then conclude with general tips we give our customers about how to prevent or prepare for database degrade issues.
Migrating from Oracle, MSSQL, or other purely relational database systems to a multimodel InterSystems IRIS is a strategic decision that requires careful planning and execution. While this transition offers significant benefits, including enhanced performance, scalability, and support for modern architectures, it also comes with challenges. In this article I will highlight some of the considerations connected to coding to ensure a successful migration. I will leave everything connected to an actual migration of structures and data outside the scope of this article.
First, when you're considering migrating to a different database system, you need to understand your business logic, whether it's on the side of the application (application server) or the database server. Basically, where do you have your SQL statements that you will need to potentially rewrite?
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.

In this article, we will explore the concepts of Dynamic SQL and Embedded SQL within the context of InterSystems IRIS, provide practical examples, andexamine their differences to help you understand how to leverage them in your applications.
InterSystems SQL provides a full set of standard relational features, including the ability to define table schema, execute queries, and define and execute stored procedures. You can execute InterSystems SQL interactively from the Management Portal or programmatically using a SQL shell interface. Embedded SQL enables you to embed SQL statements in your ObjectScript code, while Dynamic SQL enables you to execute dynamic SQL statements from ObjectScript at runtime. While static SQL queries offer predictable performance, dynamic and embedded SQL offer flexibility and integration, respectively.
Not sure there are many that connect to MS SQL to execute queries, stored procedures, etc, but our Healthsystem has many different MS SQL based databases we use within the Interoperability environment for various reasons.
With the push to moving from on-prem to the Cloud we ran into some difficulties with our SQL Gateway connections and knowing how to config them to use Microsoft Entra for Active Directory Authentication.
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.
You may have noticed that to configure a mirror for InterSystems IRIS for Health™ and HealthShare® Health Connect there is a special requirement. I wanted to go through it step by step in this article.
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.
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?
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?
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
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?
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"
The maximum number of namespaces that can be created in one instance is 2047. However, to use a large number of namespaces, you will need to configure memory accordingly.
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 ?
Hi Team, we are going to deliver a speech on a developer forum where most developers hv not used our tech before but using other database and integration technologies , Pls give us some key points on why they should adopt us and the benefits you can get, especially if you change your tech stack from others to IRIS. Thanks a lot!
If several application servers are connected using ECP, and one of them create many locks, so many that lock table became full :
Should we expect only that application server to be impacted ? (usually, when lock table is full the system became instable). Or, are other application servers going to be impacted the same way ? (because that lock table is synchronized and maintained in sync across all servers)
In the modern world, the most valuable asset for companies is their data. Everything from business processes and applications to transactions is based on data which defines the success of the organization's operations, analysis, and decisions. In this scenario, the data structures need to be ready for frequent changes, yet in a managed and governed way. Otherwise, we will inevitably lose money, time, and quality of corporate solutions.
InterSystems IRIS 2024 recently introduced the vector types.
This addition empowers developers to work with vector search, enabling efficient similarity searches, clustering, and a range of other applications.
In this article, we will delve into the intricacies of vector types, explore their applications, and provide practical examples to guide your implementation.
