Syntax option: CHECKPOINT TIMED EVERY n SECONDS For the row-cache-options clause, specifies the frequency with which the row-cache server (RCS) process checkpoints the contents of the row caches back to disk. The RCS process does not use the checkpoint frequency options of the FAST COMMIT clause. The frequency of RCS checkpointing is important in determining how much of an .aij file must be read during a recovery operation following a node failure. It also affects the frequency with which marked records get flushed back to the database for those row caches that checkpoint to the database. The default is every 15 minutes (900 seconds).
