Collector Command Enables the collection of unaligned access fault data. Format SET UNALIGNED
1 – Description
The SET UNALIGNED command enables the collection of unaligned access fault data. After you enter the GO command with unaligned access fault data collection enabled, the Collector records in the performance data file every unaligned access fault that occurs during program execution. The Collector records the faulting virtual address and program location where it occured. You must collect stack PC information if you want to use a /MAIN_ IMAGE, /CUMULATIVE or /STACK_DEPTH qualifier with the PLOT or TABULATE command in the Analyzer.
