This page lists the technologies that InterSystems products support.
This release supports the listed server platforms and operating system releases on the indicated InterSystems products.
Operating System Patches and Service Packs
Because InterSystems relies on the operating system vendor to ensure compatibility, InterSystems does not certify its products for specific operating system patches or service packs.
In the rare event that a specific patch or service pack (SP) is required to run InterSystems products, the appropriate table indicates the explicit requirement.
If a vendor introduces new features or functionality in a base version to create a new offering, InterSystems does not do additional testing but relies on the vendor to assure the quality of the base version.
This CD release (2022.3) is not supported on AIX.

A default Ubuntu setting can result in semaphore deletion. See the Ubuntu Platform Notes section of the “Preparing to Install InterSystems IRIS” chapter of the Installation Guide for more information.
Container images from InterSystems comply with the Open Container Initiative (OCI)Opens in a new tab specification and are built using the Docker Enterprise Edition engine, which fully supports the OCI standard and allows for the images to be certifiedOpens in a new tab and featured in the Docker Hub registry. InterSystems containers therefore are supported on any OCI compliant runtime engine on Linux-based operating systems, both on-premises and in public clouds.
InterSystems container images are built and tested using Ubuntu as their base operating system. These images are available for the CPU architectures shown below:
Image Operating System
|Ubuntu 20.04, 22.04||
* New for maintenance release 2022.1.1
InterSystems IRIS can be successfully deployed on cloud platforms that meet both of the following criteria:
The operating system platform is in the supported Server Platform list.
The cloud platform provides support for their infrastructure.
Customers using mirroring on cloud virtual machines should note that the public clouds require IP addresses, as opposed to virtual IPs, for mirroring.
In addition to the listed Server Platforms, the following platforms are supported for development work:
|CentOS Stream 8 x86-64*||Requires InterSystems IRIS kits for Red Hat.|
|Apple macOS 11 for x86-64||
InterSystems IRIS requires several dependencies to run on this platform. See Installing Required Dependencies for more information.
Key Management Interoperability Protocol (KMIP) is not supported on macOS.
* New at this release.
Support for development platforms is subject to the following qualifications:
Development platforms are to be used for application development only; they are not supported for deployment of applications.
The results of comparative analysis will not be underwritten by InterSystems. No valid conclusions can be drawn from performance, sizing, or other measurements taken on supported development platforms versus other supported platforms.
InterSystems will reevaluate its continued support for these platforms with each major release of InterSystems IRIS.
In most cases, this document focuses specifically on operating system versions, and only generally on the characteristics of the underlying hardware. This section is intended as a refinement of that approach, describing specific features of individual hardware offerings that InterSystems products recognize and use to their advantage.
When run on Intel 64-bit processors, beginning with the Intel® Xeon® Processor (Westmere), InterSystems IRIS makes direct use of hardware instruction(s) to perform AES encryption.
Supported File Systems
This release supports the following file systems on the specified platforms:
|Platform||Recommended File System||Other Supported File Systems|
|Apple macOS for x86-64||HFS||APFS|
|IBM AIX® for POWER System-64 (POWER 7 and higher)||JFS23|
|Microsoft Windows for x86-64||NTFS|
|Oracle Linux for x86-64||XFS|

|Ubuntu for x86-64 or ARM64||XFS||Btrfs, ext31, ext41,2, NFS|
1 The data=journal mount option for ext3/ext4 file systems is not supported.
2 When using Linux, InterSystems recommends using the ext4 file system for the journal/WIJ and the XFS file system for data files.
3 For optimum journaling performance, the cio mount option is recommended for JFS2 and VxFS file systems on all supported platforms. If you cannot use cio on VxFS, mounting with direct I/O enabled (file system mount options mincache=direct,convosync=direct) is supported for journaling.
Supported Web Servers
This release supports CSP technology on the following web servers for the indicated platforms. This does not necessarily mean that all InterSystems products run on these platforms, but rather that the InterSystems Web Gateway component does.
|Microsoft IIS 7.0 and later||
* Using Kerberos security and/or SSL for the Web Gateway on 64-bit UNIX® platforms requires 64-bit Apache.
Supported Web Browsers
InterSystems IRIS supports CSP on the web browsers listed in the following tables.
Newer versions of the browsers listed in the following table will be supported with the understanding that critical issues may be found that will have to be corrected in a major release of InterSystems IRIS. Those fixes will not be backported to earlier releases of InterSystems IRIS.
InterSystems also requires that browsers support the XML HTTP interface which limits support for some older browser versions.
|Platform||Supported Web Browsers|
|Windows||Chrome, Edge, Firefox, Opera|
|macOS||Chrome, Firefox, Opera, Safari|
Support for the InterSystems IRIS Management Portal is limited to the browsers listed in the following table. Except where noted, this includes support for InterSystems IRIS® Business Intelligence functionality. New versions released by vendors are assumed to provide backward compatibility; they are supported as described in Supported Web Browsers and are tested as they become available.
Web Browser (Platform)
|Chrome (Windows, macOS)||latest released|
|Edge (Windows)*||latest released|
|Firefox (Windows, macOS, Linux)||latest released|
*At this time, InterSystems does not fully support InterSystems IRIS® Business Intelligence functionality on Microsoft Edge.

This release supports Node.js clients on the platforms and operating system versions listed in the Supported Server Platforms table. For information about installation and configuration, see Native SDK for Node.js.
When restoring a backup or transferring a database, the target system must be the same Endianness (Big-endian or Little-endian) as the source system; for example, if a backup was created on a Big-endian system, it cannot be restored to a Little-endian system. For information, see the section on “Using cvendian to Convert Between Big-endian and Little-endian Systems” in Specialized System Tools and Utilities.
The following table identifies the Endianness of the supported server platforms for this release:
|Apple macOS for x86-64||Little-endian|
|IBM AIX® for POWER System-64||Big-endian|
|Microsoft Windows for x86-64||Little-endian|
|Oracle Linux for x86-64||Little-endian|
|Red Hat Enterprise Linux for x86-64 or ARM64||Little-endian|
|SUSE Linux Enterprise Server for x86-64||Little-endian|
|Ubuntu for x86–64 or ARM64||Little-endian|
Supported SQL Gateway Databases
The InterSystems IRIS SQL Gateway supports access to external databases from InterSystems IRIS so long as:
The external database is supported by its manufacturer. For example, InterSystems IRIS can support a connection to Oracle 10g as long as Oracle 10g is still in Oracle's extended maintenance window.
The connecting driver is compliant with the appropriate protocol. InterSystems IRIS supports ODBC 3.0 through 3.7 as well as JDBC 4.0 through 4.3.
The SQL Gateway provides features for querying external databases using the InterSystems IRIS SQL dialect. InterSystems regularly tests these features against the latest versions of the following database systems:
Microsoft SQL Server
Sybase Adaptive Server Enterprise
Supported .NET Frameworks
