Running the System Data Engine

Edit online

To start the Z Common Data Provider System Data Engine to have it stream SMF data to the Data Streamer, you use the System Data Engine started task.

Before you begin

Create the System Data Engine started task, as described in Creating the System Data Engine started task for streaming SMF data.

About this task

You use z/OS® console commands to query the status of the System Data Engine and control its operation.

Troubleshooting tip: After the System Data Engine is started, it should not stop until you stop it. If it does stop without your stopping it explicitly, review the System Data Engine job log output for possible errors.

Procedure

To run the System Data Engine, run the following console commands, where procname represents the name of the started task (such as HBOSMF).

Action	z/OS console command
Start the System Data Engine	`START procname`
Stop the System Data Engine	`STOP procname`
View System Data Engine status	`MODIFY procname,DISPLAY STATUS` The status of the System Data Engine is written to the System Data Engine `HBOOUT` data set.
View SMF record exit	`MODIFY procname,DISPLAY EXITS` The state of SMF record exit is written to the System Data Engine `HBOOUT` data set.
Refresh the policy	`MODIFY procname,REFRESH POLICY [,SHOWINPUT]` The result of the command will be displayed in the MVS console, System Data Engine `JESMSGLG` and `HBOOUT` data sets.
