The guide describes the process of integration of QCG services with the EGI Information System - Resource BDII.

The integration results in publishing information about the service in a GLUE2 complaint format through the BDII service.

The basics of EGI Information Service are described at  link.

In general, information about a grid service is produced by a service provider and transfered into the closest BDII (LDAP) instance (typically co-allocated with the service).This procedure is significantly simplified with the help of tools offered by EMI Resource Information Service (emi-resource-information-service). Consequently, the integration of new services was limited to the provisioning of a few script and configuration files.

IMPORTANT: The documentation is common for all QCG services: QCG-Broker, QCG-Computing and QCG-Notifications and varies only in some points from one service to another.

Software repositories

To install QCG-BDII (BDII for one of QCG services) please configure the system with:

  • one of QCG repositories, containing QCG specific extensions to the EGI information system. The RPMs are availeble for SL5 and SL6.
  • EMI3 (Monte Bianco) repository, which is needed for the emi-resource-information-service metapackage, providing the EGI information system base framework.

To configure aforementioned repositories please follow the instruction: QCG Software Repositories.


Install the proper package for the selected service:

  • for QCG-Broker service:
    yum install qcg-broker-egi-is-provider
  • for QCG-Computing service
    yum install qcg-comp-egi-is-provider
  • for QCG-Notification service
    yum install qcg-ntf-egi-is-provider

All the dependency packages will be automatically installed.


All the QCG-BDII packages need to be configured by providing the name of the BDII site, to which they intend to publish service information.

Run the command

qcg-info-site-config -s <site-ID>

to set appropriate data.

The list of available site-IDs can be found at

Currently configured site-ID may be displayed as follows:

qcg-info-site-config -d

Starting service

IMPORTANT: Before starting the QCG-BDII please ensure that the QCG service is properly configured and started.

To start the QCG-BDII please run (as a root):

service bdii start

By default the BDII works on port 2170.


To validate correctness of the published data the glue-validator tool can be used:

glue-validator -H localhost -p 2170 -b o=glue
