The SRBConnection actor provides users with valid accounts an ability to connect to the
SDSC Storage Resoure Broker from within the Kepler computational environment. SRB actors enable access to
a Data Grid Management System (DGMS) that provides a hierarchical logical namespace to manage
the organization of data (usually files).
This actor connects to the SRB and returns a reference to the SRB file system. This reference
can be further shared by other SRB Actors which perform various SCommands like functionality
from within the Kepler Worfklows system.
The connection reference can be propagated to all actors accessing the SRB workspace.
This actor will create a different connection object to each connected channel to allow
paralel operations.
To access the Distributed Logical File System and other SRB features each user is assigned an
SRB account which includes the following information:
- srbHost
- srbPort
- srbUserName
- srbPasswd
- srbHomeCollection
- srbDomainName
- srbDefaultResource
Required User input: The SRBConnection actor asks the user to specify the above connection parameters
and in return creates an SRB Account and outputs the created SRB file system.
The user needs to specify the following connection parameters: srbHost, srbPort,
srbUserName, srbPasswd, srbHomeCollection, srbMdasDomainHome and srbDefaultResource by double-
clicking the actor and entering the above information in the Edit Parameters Dialog Box.
Actor Output: The SRB connection reference system.
The following actor creates SRB Account and SRB file reference system with the SRB Jargon API
provided. The JARGON is a pure API for developing programs with a data grid interface and I/O for
SRB file systems.
