Connecting Existing Data Resources and Adding Roles
Up one level
This feature allows you to expose existing databases containing existing data to users of the GRIA OGSA-DAI service. To use this feature you need to have been given access to the connect-database PBAC role on the OGSA-DAI service. See the Access Control section for more information.
Before starting you should ensure that the OGSA-DAI service is listed in your client. If it does not exist you can add it by either left clicking on the "Services" menu item and selecting "Add a service", or dragging the service's WSDL link onto the "Services" entry.
Right click on the OGSA-DAI service and select "Connect existing resource".
This will open a dialog box where you can enter the details of the database you wish to connect. You are able to enter the JDBC URL of any type of database here, and also a short description of the database. No checks as to the validity of the JDBC URL are made.
Once you have connected you data resource you are able to add roles. Right click on the connected data resource and select "Connect role".
Enter a description plus the username and password of the role on your database.
After clicking "OK", the role you have created is added to the list.
Setting Permissions on Roles
See the Access Control section to learn how you can control which users have permission to subscribe to your new data resource role.
