Chapter 2: Control Data Collection › Start the Data Collection Processes

Start the Data Collection Processes

To start a data collection process, enter the following command:

$ ADVISE COLLECT START collection-definition-name

If you do not specify a collection definition, the CPD collection definition is started.

To assure proper recognition of the system configuration by the Performance Agent software, you must manually stop the data collection processes prior to binding or dissolving volume, stripe, and shadow sets, or reconfiguring hardware. For more information, see Stopping the Data Collection Processes in this chapter. Start the data collection process afterwards.

Only one primary, or CPD, data collection process per node can be active at a given time. The process runs under the user identification code (UIC) of [1,4], has the process name of PSDC$DC_SERVER, and a process base priority of 15.
