Supported Technologies

This page lists the technologies that InterSystems products support.

Supported Platforms

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.

Server Platforms

Platform
Notes
IBM AIX® 7.2, 7.3 for POWER System-64 (POWER 7 and higher)
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.
Microsoft Windows Server 2012, Server 2016, Server 2019, Server 2022, 10, 11 for x86-64  
Oracle Linux 8.2+ for x86–64
Unmodified kernel.
Red Hat Enterprise Linux 8.2+, 9.x 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 20.04, 22.04 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.

* New for maintenance release 2022.1.1

Container Platforms

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
CPU Architecture
Ubuntu 20.04, 22.04
  • Intel/AMD 64–bit
  • ARM 64–bit

* New for maintenance release 2022.1.1

Cloud Platforms

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.

Development Platforms

In addition to the listed Server Platforms, the following platforms are supported for development work:

Platform
Notes
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.

Hardware Considerations

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.

Advanced Encryption Standard (AES)

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  
Red Hat Enterprise Linux for x86-64 or ARM64 XFS ext31, ext41,2, NFS
SUSE Linux Enterprise for x86-64 XFS Btrfs, ext31, ext41,2, NFS, VxFS3
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 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.

Web Server Platform
Apache 2.4
  • Apple macOS
  • IBM AIX® for POWER System (POWER 7 and higher) *
  • Microsoft Windows
  • Oracle Linux
  • Red Hat Enterprise Linux

Supported Web Browsers

InterSystems IRIS supports CSP on the web browsers listed in the following tables.

Browser Platforms

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
Linux Firefox
Android Chrome
iOS Safari
macOS Chrome, Firefox, Opera, Safari
Portals

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)
Version
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.

ODBC Support

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.orgOpens in a new tab) — 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.orgOpens in a new tab) — 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

Node.js Support

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.

Platform Endianness

When restoring a backup or transferring a database, the target system must be the same EndiannessOpens in a new tab (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 SystemsOpens in a new tab” in Specialized System Tools and Utilities.

The following table identifies the Endianness of the supported server platforms for this release:

Platform Endianness
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:

  • IBM Db2

  • IBM Informix

  • Microsoft SQL Server

  • MySQL

  • Oracle

  • Sybase Adaptive Server Enterprise

Supported .NET Frameworks

This release supports the following Microsoft .NET frameworks:

  • .NET 5 and .NET 6
