Supported Technologies

Supported Platforms

This release supports the listed server platforms and operating system releases on the indicated InterSystems products.

• Server Platforms

• Container Platforms

• Cloud Platforms

• Development Platforms

Supported File Systems

This release supports the following file systems on the specified platforms:

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 file systems.

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.

* InterSystems supports Apache on Microsoft Windows only for upgraded instances which still use an Apache Private Web Server.

**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.

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.

*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 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 “Using cvendian to Convert Between Big-endian and Little-endian Systems”.

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

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

InterSystems supports .NET on Windows, Linux, and macOS. Versions of the .NET Framework are supported only on Windows. All InterSystems assemblies for .NET are installed to the .NET GAC (Global Assembly Cache) when InterSystems IRIS is installed.

You can use any version of Visual Studio that is supported by Microsoft for your .NET development, with the following exception: Entity Framework (EF) development requires specific Visual Studio tools to be installed in order to work with newer versions of Visual Studio. The current EF Provider supports up to VS 2019 for InterSystems IRIS. VS 2022 is not supported.

There is a separate version of the IRISClient assembly (InterSystems.Data.IRISClient.dll) for each supported version of .NET and .NET Framework. These files are located in the following subdirectories of <iris-install-dir>\dev\dotnet (see “Installation Directory” in the Installation Guide for the location of <iris-install-dir> on your system):

• .NET Framework 3.5: \dev\dotnet\bin\v3.5

• .NET Framework 4.6.2: \dev\dotnet\bin\v4.6.2

• .NET 5.0: \dev\dotnet\bin\net5.0

• .NET 6.0: \dev\dotnet\bin\net6.0

• .NET 7.0: \dev\dotnet\bin\net7.0

The current default version is .NET 7.0.

In some applications, the .NET Framework assemblies may be used to load unmanaged code libraries. Both 32-bit and 64-bit assemblies are provided for each supported version, which makes it possible to create gateway applications for 64-bit Windows that can load 32-bit libraries.

If you wish to use a version other than the default for your system, some extra configuration will be required to set the path to your desired language platform.

Supported Java Technologies

InterSystems Java products require a Java Development Kit (JDK) from Oracle (or a compatible JDK). This release supports the following JDKs:

Please contact InterSystems if you would like to take advantage of InterSystems product license sharing when running Java on Windows Terminal Servers.

Other Supported Technologies

* New at this release.

Other Supported Features

InterSystems products support the LDAP protocol, multithreaded callin, T-SQL programming extensions, the MQ Interface, Embedded Python, and IntegratedML as indicated in the following table. (Supported operating system versions are those listed in the Supported Server Platforms table.)

1 For more information, see Recommended Python Version.

2 Supports the Flexible Python Runtime feature, which allows you to use a version of Python higher than the default version of Python for your operating system.

3 The minimum version supported by InterSystems IRIS is WebSphere MQ V7.0.

4 IntegratedML is not supported on Red Hat Enterprise Linux 8 for ARM64.

5 Supported on the aixopenssl30 kit only.
