Use the Service tab to identify the external system with which this connector communicates.
Connection
- Host: enter the server IP address of the Cassandra node.
- Port: enter the port of the Cassandra node.
- Response timeout: enter the number of milliseconds after which the connection times out with a failure message if it does not receive a response. Enter zero or leave blank to wait indefinitely. This field is disabled and ignored at runtime when the Intended for field is set to queuing.
- Test connection: click this button to test the connection to the specified system. PRPC verifies the connectivity by constructing the URL based on the host and port settings but it does not confirm the ability to authenticate with the service.
- Simulations: click this button to create a simulator for this connect rule. See Connect Simulators.
The connection details may change over time, or when you move between a test system and a production system. After the ruleset version containing this connector instance is locked, you cannot update the connection fields. If your application needs to override the value in this field, complete the EndPointURL parameter of the Connect-Cassandra method in the connector activity that calls this connector instance.
Authentication
This connector can establish secured or non-secured connections.
- Use authentication: enables secured connections.
- Authentication profile: if you have enabled the authentication option, select the authentication profile, aData-Admin-Security-AuthenticationProfile instance, containing the with details required by the remote service (user name and password using BASIC authentication).
- Use SSL: enables data encryption.
- Certificate file: if you enabled data encryption, select the SSL certificate, a binary file following the <ApplicationName>:<FileName>.<Extension> format.
Error Handling
- Status value property: select a property to hold the status code of the Connect-Cassandra method. The literal value
Good identifies success. You can use the standard property @baseclass.pyStatusValue.
- Status message property: select a property to hold status descriptions or return values from the external system returned by the Connect-Cassandra method. You can use the standard property @baseclass.pyStatusMessage. This field is disabled and ignored at runtime when the Intended for field is set to queuing.
- Error handler flow: identify a flow instance to route work items that cannot continue in its current flow because this connector instance was unable to connect to the external system. The default Work-.ConnectionProblem flow provides one approach for handling such problems. See handling connector exceptions.
Processing Options
You can allow connector requests to be processed asynchronously in parallel with the calling activity, or in background by an agent. The mode of execution of each connector request is determined by the Execution Mode parameter of the Connect-Cassandra method, as enabled by the values in these two fields.
- Intended for:
Immediate execution — the connector executes synchronously; the calling activity waits for results.Queuing (response will not be available) — the connector executes asynchronously, with calls placed in a queue. The calling activity continues without waiting for results. When selected, queuing occurs only if also specified in the Connect-Cassandra method.
- Request processor: if you selected queuing in the Intended for setting, identify here a Connect Request Processor data instance that defines the classes and other characteristics of the queued connector request.
