This emulated instruction phenomenon occurs with applications that were not compiled in common mode on AIX Version 3 and that are now running on a 601 or 604 processor without being recompiled. If the application was compiled on AIX Version 4, the default compilation option is common, so only instructions that are common to all the processors would be included in the executable. For compiling in common mode on AIX Version 3.2.5, an APAR that introduces this common code is required. The Interval parameter specificies the amount of time in seconds between each report. The first report contains statistics for the time since system startup.
Subsequent reports contain statistics collected during the interval since the previous report.
If the Interval parameter is not specified, the emstat command generates a single report and then exits. The Count parameter can only be specified with the Interval parameter. If the Count parameter is specified, its value determines the number of reports generated. If the Interval parameter is specified without the Count parameter, reports are continuously generated. A Count parameter of 0 is not allowed.
