Running the Data Streamer
To start the Z Common Data Provider Data Streamer, you use the Data Streamer started task. When a policy is updated, you must stop and restart the Data Streamer to make the updated definitions take effect.
Before you begin
Create the Data Streamer started task, as described in Customizing the Data Streamer started task.
About this task
You use z/OS® console commands to control the operation of the Data Streamer and to view information about the current policy.
Troubleshooting tip: After the Data Streamer is started, it should not
stop until you stop it. If it does stop without your stopping it explicitly, review the Data
Streamer job log output for possible errors.
Procedure
To operate the Data Streamer, run the following console commands, where
procname represents the name of the started task (such as
HBODSPRO).
| Action | z/OS console command |
|---|---|
| Start the Data Streamer |
|
| Stop the Data Streamer |
|
| Refresh the Data Streamer |
Tip: After you run this command, the policy is reloaded, and the Data Streamer is
restarted.
|
| Refresh the topic list |
Tip: If Enable Multiple Kafka Topics is set to
Yes for OMEGAMON® data streams, this command will refresh the topic list in the Kafka server that the Data Streamer should read from. For more information, see Configuring the odp-topics-list.json file to collect OMEGAMON data from multiple Kafka topics. If Enable Multiple Kafka Topics is
set to No, this command takes no action. |
| Reset subscribers |
Tip: This command resets all the subscribers that send data to the backup server. After
you run the command, the Data Streamer connects to and sends data to the primary server that is
specified in the Host and Port fields for the
subscriber in the Configuration Tool.
