This topic 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.
|IBM AIX® 7.1 TL4, 7.2 for Power System-64||
InterSystems IRIS for AIX is compiled using the IBM XL C/C++ for AIX 16.1.0 compiler. If the system on which you are installing InterSystems IRIS does not have the corresponding version of the runtime already installed, you must install it.
See https://www.ibm.com/support/home/ for more information.
|Microsoft Windows Server 2012, Server 2016, Server 2019, 10 for x86-64|
|Oracle Linux 7 for x86–64||
Red Hat Enterprise Linux 7.9 for x86-64
Red Hat Enterprise Linux 8.1–8.5 for x86-64 or ARM64
To use Kerberos on the Red Hat platform, you must install the krb5-devel package in addition to the krb5-libs package. See the Red Hat Linux Platform Notes section of the “Preparing to Install InterSystems IRIS” chapter of the Installation Guide for detailed information on obtaining these components.
|SUSE Linux Enterprise Server 15 SP3 for x86-64|
|Ubuntu 18.04, 20.04 LTS for x86-64 or ARM64||
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) specification and are built using the Docker Enterprise Edition engine, which fully supports the OCI standard and allows for the images to be certified 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:

|Amazon EC2 for x86-64||
|Amazon EC2 for ARM64||
|Google Cloud Platform for x86-64||
|Microsoft Azure for x86-64||
The following restrictions apply to the preceding table:
IP addresses are required for mirroring. Virtual IP addresses are not supported for mirroring.
In addition to the listed Server Platforms, the following platforms are supported for development work:
|CentOS-7 x86-64||Requires InterSystems IRIS kits for Red Hat.|
|Apple macOS 10.15 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.
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||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 InterSystems recommends using the ext4 file system with Red Hat Clusters.
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 the Caché Server Pages (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, Internet Explorer, Edge, Firefox, Opera|
|macOS||Chrome, Firefox, Opera, Safari|
Support for the InterSystems IRIS Management Portal (including InterSystems IRIS® Business Intelligence functionality) is limited to the browsers listed in the following table. 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|
|Internet Explorer (Windows)||101|
|Internet Explorer (Windows)||111|
|Firefox (Windows, macOS, Linux)||latest released|
1 Internet Explorer 10 and 11 are not supported in Metro mode.
InterSystems products support multithreaded ODBC on most platforms.
The InterSystems ODBC driver on UNIX®-based systems supports the following driver managers:
The iODBC driver manager (see http://www.iodbc.org) — for use with the Unicode and 8-bit ODBC APIs; works with the select executable and the following drivers:
libirisodbc35.so iODBC 3.5 driver libirisodbciw35.so iODBC 3.5 unicode driver
The unixODBC driver manager (see http://www.unixodbc.org) — for use with the 8-bit ODBC API only; works with the selectu executable and the following driver:
libirisodbcur6435.so unixODBC Real Mode built 3.5 driver
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 API 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
This release supports the following Microsoft .NET frameworks:
.NET Framework Version 2.0 (Visual Studio 2005)
