The cktmpl.def file drives the checkpoint and roll forward operations. It lists commands that can be issued during the ckpdb or rollforwarddb operations to customize backup and recovery processes and to provide additional information tracking.

If needed, you can tailor the file to meet the requirements of your site. For example, if the database exists on multiple locations, checkpointing backs up each location to a separate tape or disk and, in turn, roll forward restores each location one at a time. If you want to use a different backup method or only one tape for all locations, you can edit this command file.
