Information on using the following parameters, which affect rollback and
recovery, is in the IBM Informix Dynamic Server Performance Guide. Also see Physical Logging, Checkpoints, and Fast Recovery.
Configuration Parameter
Description
FAST_RESTART_CKPT
_FUZZYLOG
Enables the flushing of dirty-pages table (DPT) records
to the physical log on fuzzy checkpoints at checkpoint during the roll-forward
phase of recovery. Like FAST_RESTART_PHYSLOG, this parameter reduces recovery
time.
FAST_RESTART_
PHYSLOG
Enables the database server to perform physical logging
on fuzzy pages while the server is running normally. Like FAST_RESTART_CKPT_FUZZYLOG,
this parameter reduces recovery time.
