One RTC tape file, which can consist of one or more tapes, should be provided for each processor in a loosely coupled complex. Run data collection simultaneously on each TPF image in the loosely coupled complex and then run data reduction for each subsystem in the TPF images.
In a loosely coupled complex, you also need to specify whether you want one specific processor to collect the complexwide data or whether any processor in the TPF system can collect the complexwide data. Specify your preference by using the ZMEAS command.
One specific processor should collect the complexwide data if you want to use the concurrency filter lock facility (CFLF) high-water marks as a tuning aid. Do not specify a specific processor if there is a possibility of contention for the CFLF locks. If contention occurs for the CFLF locks, check the data reduction reports to determine which processors experienced the contention. However, this information is not available if one specific processor is collecting complexwide data.
