Supported environments
This release is supported on certain hardware platforms and operating systems, and is tested on specific virtualization environments.
Any new updates to these support statements can be found in the Supplementary documentation technote.
AIX systems
The 32-bit and 64-bit releases of the SDK and Runtime environment run on hardware that supports
the following platform architectures:
- IBM® POWER® 5
- IBM POWER 6
- IBM POWER 7
- IBM POWER8®
IBM
POWER9™
IBM
Power10
The following table shows the operating systems supported for each platform architecture. The
table also indicates whether support for an operating system release was included at the
general availability (GA) date for the release, or at a later date in a service refresh
(SR) or fix pack (FP):
| Operating system | 32-bit release | 64-bit release |
|---|---|---|
 AIX® 6.1 TL9 |
GA | GA |
| AIX 7.1 TL3 (see note 1) | GA | GA |
| AIX 7.2 (see note 2) | SR2 | SR2 |
| AIX 7.3 (see note 3) | SR7 | SR7 |
Notes:
- For IBM
POWER8 and later systems, the minimum supported level for
AIX 7.1 is TL3. For IBM Power10 systems, AIX 7.1 is supported
only in POWER9 compatibility mode.
- AIX 7.2 is supported only on IBM
POWER 7 and later processors. For IBM Power10 systems, AIX
7.2 is supported only in POWER9 compatibility
mode.
- AIX 7.3 is supported only on IBM POWER8 and later processors.
To avoid problems when using Java™ runtime environment, ensure that you have any prerequisite AIX APARs installed. For further information about the APARs needed for an AIX level, see https://www.ibm.com/support/docview.wss?uid=swg21605167.
If you want to use the Java 2D graphics pipeline, based on the X11 XRender extension, you must install the libXrender.so library, version 0.9.3 or later.
Linux systems
There are a number of distributions provided for the Linux® operating system.
For Linux on x86, the following platform architectures are supported:
- x86-32
- x86-64
For Linux on IBM
POWER, the following hardware is supported:
- IBM POWER 6
- IBM POWER 7
- IBM POWER8
- IBM
POWER9
- IBM Power10
Note: IBM
POWER8 and later systems can operate in both Big Endian
(BE) or Little Endian (LE) format. An LE version of the SDK is available for 64-bit Power® Systems to support those operating systems that are available in LE
format. For example, SUSE Linux Enterprise Server (SLES) 12
or Ubuntu 18.04 LTS.
For Linux on IBM Z®, the following hardware is supported:
IBM z16™ (64-bit SDK only; the 31-bit SDK is not supported on this hardware level)
IBM
z15®- IBM z14
- IBM z13®
- IBM zEnterprise® EC12
- IBM zEnterprise BC12
- IBM zEnterprise 114
- IBM zEnterprise 196
