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.
Main installation procedure
The DIS Installation needs a manual change on the DHN behaviour. The HNM in general is configured to publish the RI profiles of the codeployed services and the related DHN profile on the root VO. In case the HNM is codeployed toghether with DIS Services (so it has to register Profiles using the codeployed instance of the DIS-Registry) the DHN has to be configured to act as a "root" DHN. The related HNMService inthis context will create all the DIS Running Instance Profiles (togheter with the DHN profile), but it will be DIS-Registry itself that will register these profiles.
DHN root Installation
The "root" DHN has to be installed following the Admin guide. Once the installation has been done, the only change to standard DHN installation is on the HNM Service JNDI file:
- The "rootDHN" parameter has to be set to true ( the DIS DHN is also of type Static)
DIS-IC Installation
TBD
DIS-Broker Installation
The DISBroker ServiceArchive 0_3_0 can be downloaded from the Eng repository . These are the installation steps to follow:
- Unpack the ServiceArchive tar.gz file;
- type globus-deploy-gar org_diligentproject_informationservice_disbroker.gar to deploy the DIS-Broker Service on the local container;
DONE!
DIS-Registry Installation
The DISRegistry ServiceArchive 0_3_0 can be downloaded from the Eng repository . These are the installation steps to follow:
- Unpack the ServiceArchive tar.gz file;
- type globus-deploy-gar org_diligentproject_informationservice_disregistry.gar to deploy the DIS-Registry Service on the local container;
DONE!
Security Setting
All DIS services can be configured to run in a secure/unsecure context. In case the VO to deploy has to run in a secure way the stardard installation will provide server-config.wsdd files that already contain security-descriptor for DIS services. In case the VO has to be deployed without security just:
- enter the specific container folder of DIS services (i.e for DIS-Registry : $GLOBUS_LOCATION/etc/org_diligentproject_informationservice_disregistry )
- copy the content of deploy-server.wsdd_NOSEC file inside server-config.wsdd file
- this will remove the link to the service security-descriptor and has to be done for all DIS services.
Post-installation configuration
After the deployment the VOMap for the VO the DIS installed refers to has to be properly configured. So in case of /diligent root VO just change the file VOMap_diligent.xml located into the $GLOBUS_LOCATION/etc/org_diligentproject_keeperservice_hnm/VOMaps modifyng service endpoint according to your DIS installation. In case of sub-VO DIS installation just creates a VOMap_<yourSubVo>.xml file containing as above the endpoint to your DIS installation.
Testing and verifying the installation
Provide instructions that will assist the administrator in verifying that the service has been installed and is running appropriately. Troubleshooting of the installation together with error messages and common compensation actions should be provided in detail in chapter 4.
