Certain restrictions apply when using the FABHBSIM utility.
FABHBSIM has the following restrictions:
- The PSB and DBDs used must be identical with those used in the original run that was traced. Do not modify the PSB or the DBD between the traced run and the execution of FABHBSIM. The database itself can be modified with ISRT, DLET, or REPL, and reorganization activities.
- The timing estimates of CAB I/O provided on the CAB Statistics report are not accurate when FABHBSIM is run.
- FABHBSIM does not support the tuning of buffer handlers for a PHDAM or a PHIDAM database.
