ZUDFC START-Start Data Collection

Use this command to start data collection.

Requirements and Restrictions

Format




TIME-time
specifies the duration of the measurement period in minutes, where time is a 2-digit number from 1-60. If you do not specify this parameter, data collection continues until you enter a ZUDFC STOP command. The ZUDFC STOP command can be used to terminate data collection before the end of the measurement period.

PROCESSOR-ALL
starts data collection on all processors. If you do not specify this parameter, data collection will start only on the current processor.

PROCESSOR-ALL is valid only on TPF systems.

SSU-ALL
starts data collection for all subsystem users in the subsystem. This parameter produces one set of data for all SSUs. If you do not specify this parameter, data collection will start only on the SSU for the ZUDFC command that was entered.

SSU-ALL is valid only on TPF systems.

Additional Information

When you specify the PROCESSOR-ALL and TIME parameters, if the initiating processor is not active when data collection is going to end, data collection does not stop automatically on any other processor. In this occurs, you must stop data collection on the other processors manually with the ZUDFC STOP command. In addition, the PROCESSOR-ALL totals are lost.

Examples

The following example displays data collection started on all processors.

|User:   ZUFDC START PROCESSOR-ALL                                               |

|System: UDFC0001I 13.40.03 DATA COLLECTION STARTED ON PROCESSOR B               |

The following example displays data collection that is started on all processors and will run for 30 minutes.

+--------------------------------------------------------------------------------+
|User:   ZUFDC START TIME-30 PROCESSOR-ALL                                       |
|                                                                                |
