Conventions

The install directory is different depending on the operating system. In this documentation, this directory is referred to as variable names. The actual directory location for each platform is indicated in this topic.

In the following directories, <version> is a single-digit version number that represents the product version, and <release> is a single-digit version number that represents the product release. <arch> is one of the following Linux® architectures:
Table 1. Linux architecture values for directories
Linux architecture Value of <arch>
x-86 32-bit i386
AMD 64-bit x86_64
PPC 32-bit ppc
PPC 64-bit ppc64
PPC 64-bit (Little Endian) ppc64le
IBM Z® 31-bit s390

install_dir
The installation directory is referred to as install_dir in this documentation. Where the SDK is installed by using an installer program, the following default installation directory is used:
  • AIX®: /usr/java<version>[_64]/
  • Linux: /opt/ibm/java-<arch>-<version><release>/
  • Windows: C:\Program Files\IBM\Java<version><release>\
  • z/OS®: /usr/lpp/java/J<version>.<release>[_64]/
For example:
  • AIX: /usr/java8_64/
  • Linux: /opt/ibm/java-ppc64le-80/
  • Windows: C:\Program Files\IBM\Java80\
  • z/OS: /usr/lpp/java/J8.0_64/
If an installer is not used, install_dir refers to the location that is chosen for the SDK program files. For example, if the SDK is embedded in an IBM product, refer to the documentation for that product to determine the directory location.
