# This script recreates offline_db files from the latest checkpoint. If it fails, then
# check to see if the most recent checkpoint in the /p4/INSTANCe/checkpoints directory is
# bad (ie doesn't look like the right size compared to the others), and if so, delete it
# and rerun this script. If the error you are getting is that the journal replay failed,
# then the only option is to run live_checkpoint.sh script.
#
# This script is using the following external variables:
#
# SDP_INSTANCE - The instance of Perforce that is being backed up. If not
# set in environment, pass in as argument to script.
#
# 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.
#
