DILIGENT Information Service (DIS)
The following components compose the DILIGENT Information Service:
- DIS-IP (Library) – The DIS-IP is responsible for registering/unregistering a group of resource properties as Aggregator Source to one or more DIS-ICs. It also allows to register/unregister groups of Topics in the DIS-Broker.
- DIS-HLSClient (Library) – The DIS-HLSClient is a library used by DILIGENT services to access the information maintained by the DILIGENT Information Service. Using a DIS-HLSClient it is possible to query a DIS-IC to discover Profiles or WS-Resource properties.
- DIS-IC (WSRFService) – This service is the Information Collector (IC) of all the data published in the DIS. It is implemented as Aggregator Sink that collects RPs from the registered (via DIS-IP) Aggregator Sources.
- DIS-BDIIClient (WSRFService) – This service is in charge of harvesting resource information from the BDII Server1 it has been configured to interact with. The gathered information is manipulated in order to make it compliant with the schema adopted in DILIGENT. Then such information is published as WS-Resources via the DIS-IP and as a DILIGENT Resource of type gLiteResource using the mechanism offered by the DIS-Registry Service.
- DIS-Registry (WSRFService) – This service provides registration and un-registration facilities for the DILIGENT resources profiles.
- DILIGENTProvider (Library) – This operation provider adds resource properties to the group of properties registered by a service in the DIS-IC. This additional information allows enlarging the spectrum of functionalities offered to identify the source that publishes the data and to perform fine-grained queries.
- DIS-Broker (WSRFService) – This service provides registration/unregistration of Topics (events to be notified on) for DILIGENT Services. This allows clients to subscribe to/unsubscribe from topics without having to know the physical locations of the services that expose them.
Pre-installation setup
The DIS core Services (DIS-Registry, DIS-Broker and DIS-IC), are VO specific services ( there is the need of an instance of those services for each VO). Starting from the root VO ( the "diligent" root VO), but at the time being also all the sub-VO (i.e. ARTE) need a manual installation. The root DIS is the first DILIGENT services that has to be installed in the infrastructure: it will contain all DHN Profiles and RI Profiles of Services running on the root VO and DHN profiles of Sub-VO node ( that can be assigned to sub-VOs by VO Managers).
The Installation of the root DIS requires at least 3 nodes:
- the DIS-Registry DHN
- the DIS-Broker DHN
- the DIS-IC DHN
The DIS-BDIIClient is a VO specific Services and is no needed at root VO level. In order to speed up the performance and exploits the distributed nature of the GT4 Aggregator Framework, the best DIS Services deployment strategy would be:
- Deploy the DIS-Broker and the DIS-Registry on the same DHN
- Deploy the DIS-IC on a separate DHN.
The following installation documentation assumes that this is the target deployment schema.
