Documentation Conventions

This section describes the types of conventions used throughout this guide:

General Conventions
Conventions Referring to Directories

General Conventions

The following general conventions are used in this guide:

File and directory paths are given in UNIX^® format (with forward slashes separating directory names). For Windows versions, the directory paths are the same, except that backslashes are used to separate directories.
URLs are given in the format:

http://server.domain/path/file.html

In these URLs, server is the server name where applications are run; domain is your Internet domain name; path is the server’s directory structure; and file is an individual filename. Italic items in URLs are placeholders.

Font conventions include:
The monospace font is used for sample code and code listings, API and language elements (such as function names and class names), file names, pathnames, directory names, and HTML tags.
Italic type is used for code variables.
Italic type is also used for book titles, emphasis, variables and placeholders, and words used in the literal sense.
Bold type is used as either a paragraph lead-in or to indicate words used in the literal sense.
Installation root directories for most platforms are indicated by install_dir in this document. Exceptions are noted in Conventions Referring to Directories.

By default, the location of install_dir on most platforms is:

Solaris and Linux file-based installations:

  user’s home directory/sun/appserver7

Windows, all installations:

  system drive:\Sun\AppServer7

For the platforms listed above, default_config_dir and install_config_dir are identical to install_dir. See Conventions Referring to Directories for exceptions and additional information.

Instance root directories are indicated by instance_dir in this document, which is an abbreviation for the following:

default_config_dir/domains/domain/instance

UNIX-specific descriptions throughout this manual apply to the Linux operating system as well, except where Linux is specifically mentioned.

Conventions Referring to Directories

By default, when using the Solaris package-based or Linux RPM-based installation, the application server files are spread across several root directories. This guide uses the following document conventions to correspond to the various default installation directories provided:

install_dir refers to /opt/SUNWappserver7, which contains the static portion of the installation image. All utilities, executables, and libraries that make up the application server reside in this location.
default_config_dir refers to /var/opt/SUNWappserver7/domains, which is the default location for any domains that are created.
install_config_dir refers to /etc/opt/SUNWappserver7/config, which contains installation-wide configuration information such as licenses and the master list of administrative domains configured for this installation.
