4.1 Flow of system operation
(1) Starting the system
(2) Using queries and query groups
If necessary, you can use queries and query groups by performing the operations explained below.
- Re-execute queries
Re-execute queries that have already been executed. For details about how to re-execute queries, see 4.3.1 Re-executing queries.
- Display the status of query groups
Display the status of query groups and the accumulation status of input and output streams. For details about how to display the status of query groups, 4.3.2 Displaying the status of query groups.
(3) Displaying analysis results on a dashboard
The following describes how to use the standard adaptors to output stream data summary analysis results to a dashboard:
- Start Dashboard Server
Start the Web server, PRF daemon, and Web container server; then start Dashboard Server. For details about how to start Dashboard Server, see 4.5.1 Starting Dashboard Server.
- Use Dashboard Viewer to display analysis results
Use Dashboard Viewer to open the dashboard window and display analysis results. For details about how to use Dashboard Viewer to display analysis results, see 4.5.2 Using Dashboard Viewer to display analysis results.
- Shut down Dashboard Server.
Shut down the Web container server, PRF daemon, and Web server, and then shut down Dashboard Server. For details about how to shut down Dashboard Server, see 4.5.3 Shutting down Dashboard Server.
(4) Shutting down the system
Terminate the adaptors, query groups, and SDP server in the order described below, and then shut down the system.
- Terminate the adaptors
Terminate the standard or custom adaptors. If you are using custom adaptors in the RMI connection mode, you must implement a termination process within the custom adaptors because Stream Data Platform - AF commands cannot be used to terminate them.
For details about how to terminate the standard adaptors, see 4.4.1 Terminating adaptors (standard adaptors); for details about how to terminate custom adaptors, see 4.4.2 Terminating adaptors (custom adaptors).
- Check the status of adaptor groups
Check that the adaptor groups have terminated normally. For details about how to check the status of adaptor groups, see 4.2.6 Checking the status of adaptor groups.
- Terminate the query groups
Terminate the query groups. For details about how to terminate the query groups, see 4.4.3 Terminating query groups.
- Shut down the SDP server
Shut down the SDP server. For details about how to shut down the SDP server, see 4.4.4 Shutting down the SDP server.
