Terminology

Specific conventions are used to describe methods and classes, and command-line options.

Methods and classes are shown in normal font:

Command-line options are shown in bold. For example:

Options shown with values in braces signify that one of the values must be chosen. For example:

-Xverify:{

remote |

all |

none}

with the default underscored.

Options shown with values in brackets signify that the values are optional. For example:

-Xrunhprof[:help][<suboption>=<value>...]

In this information, any reference to Oracle is intended as a reference to Oracle Corporation.


Directory conventions

In the following directories, <version> is a single-digit version number that represents the product release.

install_dir

The installation directory is referred to as install_dir in this documentation. The default installation directory is as follows:

  • C:\Program Files\IBM\Java<version>0\

For example:

  • C:\Program Files\IBM\Java70\

lib_dir

The Java™ library directory is referred to as lib_dir in this documentation. The library directory is as follows:

  • install_dir\jre\bin\


Java virtual machine (JVM) version conventions

The JVM version is referred to as <vm_version> in this documentation. To find out which version of the JVM you are using, enter the following command: 

java -version
The following example output shows the JVM version in bold text, in the line beginning with IBM J9 VM: 
java version "1.7.0"
Java(TM) SE Runtime Environment (build pxi3270sr1-20120201_02(SR1))
IBM J9 VM (build 2.6, JRE 1.7.0 Linux x86-32 20120131_101270 (JIT enabled, AOT enabled)
J9VM - R26_JVM_26_20120125_1726_B100726
JIT - r11_20120130_22318
GC - R26_JVM_26_20120125_1044_B100654
J9CL - 20120131_101270)
JCL - 20120127_01 based on Oracle 7u3-b02
java version "1.8.0"
Java(TM) SE Runtime Environment (build pwi3280-20121029_01)

JIT  - dev_20121009_26996
GC   - R27_head_20121022_1139_B125796
J9CL - 20121024_125996)
JCL - 20121015_01 based on Oracle 8-b54
The format of <vm_version> is digits only, so in the previous example, <vm_version> is 26.
