Deploying Data Services via the Command-line

To deploy a data service:

1. Run the following command from within the OGSA-DAI WSRF binary distribution directory:

   $ ant deployService -Ddai.container=/path/to/Web/services/container
     -Ddai.service.name=service/name
   

   • dai.container specifies the path to your Web services container. Alternatively you can define an OGSADAI_CONTAINER environmental variable to hold this value.
   • dai.service.name specifies the name of the service. For example: -Ddai.service.name=ogsadai/DataService This specifies a data service whose URL will be http://HOST:PORT/wsrf/services/ogsadai/DataService.
   • Providing the flag -Ddai.service.config=y requests that the data service support dynamic service configuration. See the configurable data services and exposing data service resources via data services pages for more information.
   • You also have the option of specifying the support for concurrent requests that each resource exposed by the service will provide. This can be done via the following flags:
     • -Ddai.max.requests=N specifies the number of requests that each resource can run concurrently. If this flag is ommited the default of 10 is used.
     • -Ddai.max.queue.length=N specifies the number of requests that each resource can queue if its maximum number of concurrent requests has been reached. Once an existing request completes the next request in the queue will start executing. If this flag is ommited the default of 20 is used.
2. The data service will be deployed onto your Web services container. You will need to shutdown and restart your container before clients are able to access the new data service.
