# This script recreates offline_db files from the latest checkpoint. If it fails, then
# the only option is to run live_checkpoint.sh instead.
#
# This script can be called directly specifying instance, or using the p4master_run script
# in order to properly set the environment variables for the script to reference. It
# sources /p4/common/bin/p4_vars to set the environment variables that this script
# depends on.
#
# This script is using the following external variables:
#
# SDP_INSTANCE - The instance of Perforce that is being backed up. Always an
# integer value.
#
# P4HOME - Server's home directory.
# P4BIN - Command line client name for the instance being backed up.
# P4DBIN - Server executable name for the instance being backed up.
# P4ROOT - Server's root directory. p4/root, p4_N/root
# P4PORT - TCP/IP port for the server instance being backed up.
# P4JOURNAL - Location of the Journal for the server instance being backed up.
#
#
