Administrator Guide

This Guide covers the installation, configuration, and maintenance of gCore.

Before you Begin

The following software is a prerequisite for the installation of gCore:

• A platform compatible or made compatible with GT requirements.
• J2SE 1.5.08 SDK or greater. Sun's reference implementation is recommended, but versions from IBM, HP, or BEA should work equally well.
• Ant 1.6.5+ to build gCF sources or to develop services with it.
• a SVN client to install gCore from the SVN repository.
• GNU tar to install gCore from archived distributions.
• sudo to execute shell commands with controlled super-user privileges.
• A ntp server to synchronise your clock with other machines' for correct credential validation.
• A static IP address for all but the simplest testing scenarios.

Installation

gCore may be installed from a SVN repository, or else from pre-packaged archives. In the first case, installing gCore is tantamount to downloading it into a directory of choice. In the second case, simply expand the downloaded archive into a directory a choice. In either case, your installation directory will look as follows:

Here is the directory structure once the gCore distribution is uncompressed:

gCore LOCATION
|
|-bin
|
|-config
|
|-endorsed
|
|-etc
|
|-lib
|
|-libexec
|
|-share
       |
       |-gcore_tools
       |-globus_wsrf_common
       |-globus_wsrf_core
       |-globus_wsrf_core_registry
       |-globus_wsrf_msd_userful_rp_schema
       |-globus_wsrf_test
       |-globus_wsrf_tools
       |-licences 
       |-schema       

Here is the list of the most significant folders:

• bin contains the commands
• config contains the GHN configuration files
• etc is used to place container and service-specific configurations
• lib contains service & 3rd-party software
• share/gcube_tools contains the gCore build scripts
• share/schema contains service, standard and gCore-specific interfaces

Dealing with Globus

In order to deal with the underlying Globus technology, the following steps are needed:

1. export GLOBUS_LOCATION to the gCore LOCATION
2. export PATH to gCore bin
3. configure ${GLOBUS_LOCATION}/etc/globus_wsrf_core/server-config.wsdd by specifying the hostname as value of the logicalHost parameter

<deployment name="defaultServerConfig" xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java" xmlns:wsa="http:/
/schemas.xmlsoap.org/ws/2004/03/addressing" xmlns:wsnt="http://docs.oasis-open.org/wsn/2004/06/wsn-WS-BaseNotification-1.2-draft-01.xsd" xmlns:wsrp="http://d
ocs.oasis-open.org/wsrf/2004/06/wsrf-WS-ResourceProperties-1.2-draft-01.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <globalConfiguration>
        <parameter name="logicalHost" value="localhost"/>
        [...]
    <globalConfiguration>
</deployment>

To test it: start GHN gcore-start-container -nosec (by default on 8080, otherwise start with -p <port>)

GHN Passport

The main configuration file of gCore is $GLOBUS_LOCATION/config/GHNConfig.xml:
