=head1 NAME

JATS Environment Variables

=head1 SYNOPSIS

JATS makes use of a number of Environment Variables (EnvVars) to provide

configuration information.

There are two classes of EnvVars used by JATS. These are:

=over

=item 1 JATS Configuration

These EnvVars have a GBE_ prefix. These are detailed in this document.

=item 2 Toolset location

Some of the build tools used by JATS use EnvVars to specify the location

of the installed tool. 

Ideally tools should be installed in their default location and JATS should be

preconfigured to use this default location. Configuration allows for exceptions.

=back

=head2  Environment variables

Environment variables that specify a path may be set to '-', or 'none' in order

to force an undefined path.

=over 8

=item GBE_MACHTYPE

This specifies the machine that the script is running on. This is fixed within

the startup script.

=item GBE_HOSTMACH (internally set)

This is a copy of GBE_MACHTYPE.

Unlike GBE_MACHTYPE, this copy is not modified by makefiles.

=item GBE_HOSTNAME (internally)

This EnvVar is the name of the current host. It is available to be used within

scripts that need to stamp build files.

=item GBE_PERL

This specifies the full path the to B<ActiveState> perl binary.

=item GBE_CORE

This specifies the path the to B<JATS> installation.

=item GBE_CACHE_JATS

When set to a non zero value will force JATS to transfer a working copy to the

local dpkg_archive. This will speed up the build process because the utilities

will be run from a local drive; not a network drive.

This will only operate if JATS is run from dpkg_archive.

=item GBE_DPKG_STORE (optional)

This is the global read-only archive store. It will only be used to source

packages after all other archive stores have been examined. The GBE_DPKG_STORE

is intended to provide a read-only or remote repository within a global

environment.

=item GBE_DPKG

This is the official archive. Some tools will publish packages directly to this

archive.

This item is mandatory and must address a valid directory.

=item GBE_DPKG_CACHE (optional)

This the path to a local package archive cache. This is used to speed access to

main repository. The cache should be on the users local machine and not a network

drive.

=item GBE_DPKG_LOCAL (optional)

This the path to a group wide local package archive. This may be used to store

non-official packages that are under test or development.

=item GBE_DPKG_SBOX (optional)

This the path to a sandbox specific package archive. This may be used to store

non-official packages that are under test or development within the current sandbox.

The archive is located by searching from the current directory to the root of

the filesystem for a directory called 'sandbox_dpkg_archive'.

It is intended that a group of packages that are being developed in the same

sandbox will share the same sandbox_dpkg_archive.

Jats will ignore the version number when dealing with packages in GBE_DPKG_SBOX.

This is done to simplify the publishing and consuming of packages in the sandbox.

This should not be set by a user. It will be calculated by JATS and passed to

JATS tools and utilities.

=item GBE_SANDBOX (optional)

This the path to a sandbox base directory. It is intended that a group of

packages that are being developed in the same sandbox will share the same

sandbox_dpkg_archive.

This should not be set by a user. It will be calculated by JATS and passed to

JATS tools and utilities.

=item GBE_DPLY (optional)

This the path to the deployment archive.

This archive will be used when publishing special deployment package. This is

not the norm.

This variable may be set on a per-project basis.

=item GBE_PLATFORM (deprecated)

This specifies the names of platforms that will be built and made. This should

be empty. Use B<GBE_BUILDFILTER> to provide better control.

=item GBE_BUILDFILTER (desirable)

This is a filter string that specifies which platforms to create makefiles

for. This variable is used to prevent JATS from creating Solaris and Linux

targets on a Windows machine and visa-versa.

=item GBE_JATS_VERSION (optional)

Specifies the version of JATS that the user will use. This is the same as

specifying the -version=xx.xx.xx option on the command line, but because it is

in the environment the required version will be used by all invocations of JATS.

=item GBE_ABT (optional)

Used by the Auto Build Tool to indicate that the build is being performed by the

ABT. When set the build environment will be modified to suite the ABT. Some

operations may be relaxed.

Currently set to 1 to set it.

=item GBE_VIEWBASE (optional)

Used by the 'release' utility to provide a user configurable base directory for

the creation of static views.

=item GBE_RM_LOCATION (optional)

Used by tools that interface to Release Manager: primarily the (ABT) Auto Build Tools.

Specifies the location of the Release Manager Database. This is a database url

of the form jdbc:subprotocol:subname as used by java.sql.DriverManager.getConnection()

C<Example: jdbc:oracle:thin:@auperaora03:1521:RELEASEM>

=item GBE_RM_USERNAME (optional)

Used by tools that interface to Release Manager: primarily the (ABT) Auto Build Tools.

Specifies a USERNAME with access to the Release Manager Database.

=item GBE_RM_PASSWORD (optional)

Used by tools that interface to Release Manager: primarily the (ABT) Auto Build Tools.

Specifies a PASSWORD to be used in conjunction with GBE_RM_USERNAME to access

the Release Manager Database.

=item GBE_RM_URL (optional)

Used by tools that interface to Release Manager: primarily the (ABT) Auto Build Tools.

Specifies the base URL of RElease Manager

=item GBE_DM_LOCATION (optional)

Similar to GBE_RM_LOCATION, but is used to access the Deployment Manager Database.

If GBE_DM_LOCATION is not provided, then GBE_RM_LOCATION will be used.

=item GBE_DM_USERNAME (optional)

Similar to GBE_RM_USERNAME, but is used to access the Deployment Manager Database.

=item GBE_DM_PASSWORD (optional)

Similar to GBE_RM_PASSWORD, but is used to access the Deployment Manager Database.

=item GBE_DM_URL (optional)

Similar to GBE_DM_URL, but is used to access the Deployment Manager Database.

=item GBE_SVN_URL (Required for Subversion support)

Specifies the URL of the Subversion repository to be used by the Subversion

oriented JATS commands. The URL should contain the protocol, the repository

host and the path to the root of the repository, but not the name of the

repository. ie: C<svn://auperaws996vm21>

=item GBE_SVN_PATH (optional)

If provided this will be used to locate the 'svn' utility used by the SubVersion

support functions. If not provided, then the utilities assume that 'svn' is in the

users PATH. 

Providing the path will prevent JATS from searching for the utility.

=item GBE_SVN_USERNAME (optional)

Subversion repository credentials. If provided it will be used, otherwise the

native svn credential mechanism will be used.

=item GBE_SVN_PASSWORD (optional)

Subversion repository credentials. If provided it will be used, otherwise the

native svn credential mechanism will be used.

=item GBE_MAKE_TYPE (internal)

This EnvVar is set when a Makefile is being processed by 'make'. The value

indicates the type of the build. It will be either P(Production), D(debug)

or C(Common).

=item GBE_MAKE_TARGET (internal)

This EnvVar is set when a Makefile is being processed by 'make'. The value

is set current target platform name.

=item GBE_MAKE_CFG (internal)

This EnvVar is set when a Makefile is being processed by 'make'. The value

is set to the path of the parsed makefile.pl data gathered when the makefile

was created.

=item GBE_MAKE_CMD (internal)

This EnvVar is set when a Makefile is being processed by 'make'. The value

is set current make command being processed.

=item GBE_SCRIPT (internal)

This EnvVar contains the path and comamnd line argument to the current JATS

command.

Its primary purpose is to determine the location of the jats startup script:

jats.bat or jats.sh.

=item GBE_UNIX (internal)

This EnvVar will be set to 1 on Unix systems and 0 on Windows Systems. The value

is calculated by JATS and cannot be set externally.

=item USER (set if undefined)

This EnvVar will be set to the current JATS user. It may be set externally,

but normally this is not required as JATS will determine the user in a

platform specific manner.

=back

=head2 Location of EnvVar definitions

The location of the EnvVars used by JATS is dependent on the target machine

type.

=head3 Windows 

Under Windows, the best place to specify the JATS EnvVars is in the JATS.BAT

file itself. The location of the JATS.BAT file being used is provided by the '

jats vars' utility.

=head3 Solaris

Under Solaris, the JATS EnvVars are set in /etc/profile. These can be

overridden by users in there own profile, but this is not encouraged as the

JATS configuration is normally machine-wide.

The jats.sh script, used to start jats may provide deafult definitions. The

location of this script is provided by the 'jats vars' utility.

=head3 Linux

Under Linux, the JATS EnvVars are set in  /etc/profile.d/jats.sh. These can be

overridden by users in there own profile, but this is not encouraged as the

JATS configuration is normally machine-wide.

The jats.sh script, used to start jats may provide deafult definitions. The

location of this script is provided by the 'jats vars' utility.
