Overview and Configuration of the Data Service
Overview
The GRIA Data Service is used to manage "data stagers". A data stager is a container for a single file (or zip file). It has a unique identifier and an access control system for determining who can read and write the data. Clients can use the service to create new stagers, upload and download data, transfer data between stagers, and control others' access to the data.
Two items of configuration must be given before the Data Service can be used:
- The location of the root data directory
- The service stores any uploaded data inside this directory. If the Data Service is going to be used with a Job Service and jobs are going to execute on a cluster then the cluster's machines need to be able to read and write to this directory.
- A list of trusted management services
- Normally, you can just click to accept the default management service. This is the SLA management service from the GRIA Service Provider Management package. Note that if the GRIA Basic Application Services package is deployed on a different machine to the GRIA Service Provider Management package, some additional access control setup is required. This is described in Links with Other Services section of the Service Provider Management user guide. As an alternative to configuring the service to be managed, you can make it unmanaged (or "free"), by clicking the button.
