USAGE for load_checkpoint.sh v2.3.6:

load_checkpoint.sh <checkpoint> [-i <instance>] [-s <ServerID>] [-c] [-l] [-r] [-b] [-y] [-L <log>] [-si] [-v<n>] [-D]

or

load_checkpoint.sh [-h|-man|-V]


DESCRIPTION:
	This script loads a specified checkpoint into /p4/N/root and /p4/N/offline_db,
	where 'N' is the SDP instance name.

	At the start of processing, preflight checks are done. Preflight checks
	include:
	* The specified checkpoint and corresponding *.md5 file must exist.
	* The $P4ROOT/server.id file must exist, unless '-s' is specified.
	* The $P4ROOT/license file must exist, unless '-l' is specified.
	* Basic SDP structure and key files must exist.

  	If the preflight passes, the p4d_N service is shutdown, and also the
	p4broker_N service is shutdown if configured.

	Next, the specified checkpoint is loaded. Upon completion, the Helix Core
	server process, p4d_N, is started.

	If the server to be started is a replica, the serviceUser configured for
	the replica is logged into the P4TARGET server.  Any needed 'p4 trust' and
	'p4 login' commands are done to enable replication.

	Note that this part of the processing will fail if the correct super user
	password is not stored in the standard SDP password file,

	/p4/common/config/.p4passwd.p4_N.admin

	After starting the server, a local 'p4 trust' is done if needed, and then
	a 'p4login -service -v' and 'p4login -v'.

	By default, the p4d_N service is started, but the p4broker_N service is not.
	Specify '-b' to restart both services.

ARGUMENTS AND OPTIONS:
 <checkpoint>
	Specify the path to the checkpoint file to load.

	The file may be a compressed or uncompressed checkpoint, and it may bea case
	sensitive or case-insensitive checkpoint.  The checkpoint file must have a
	corresponding *.md5 checksum file in the same directory, with one of two name
	variations: If the checkpoint file is /somewhere/foo.gz, the checksum file may
	be named /somewhere/foo.gz.md5 or /somewhere/foo.md5.
	
 -i <instance>
	Specify the SDP instance. This can be omitted if SDP_INSTANCE is already
	defined.

 -s <ServerID>
	Specify the ServerID.  This value is written into $P4ROOT/server.id file.

	If no $P4ROOT/server.id file exists, this flag is required.

	If the $P4ROOT/server.id file exists, this argument is not needed. If this
	'-s <ServerID>' is given and a $P4ROOT/server.id file exists, the value in
	the file must match the value specified with this argument.

 -c	Specify that SSL certificates are required, and not to be generated with
	'p4d_N -Gc'.

	By default, if '-c' is not supplied and SSL certs are not availalbe, certs
	are generated automatically with 'p4d_N -Gc'.

 -l	Specify that the server is to start without a license file. By default, if
	there is no $P4ROOT/license file, this script will abort.  Note that if '-l'
	is specified and a license file is actually needed, the attempt this script makes
	to start the server after loading the checkpoint will fail.

 -r	Specify '-r' to replay only to P4ROOT.  By default, this script replays both
	to P4ROOT and the offline_db.

 -b	Specify '-b' to start the a p4broker process (if configured).  By default
	the p4d process is started after loading the checkpoint, but the p4broker
	process is not. This can be useful to ensure the human administrator has
	an opportunity to do sanity checks before enabling the broker to allow
	access by end users (if the broker is deployed for this usage).

 -y	Use the '-y' flag to bypass an interactive warning and confirmation
	prompt.

 -v<n>	Set verbosity 1-5 (-v1 = quiet, -v5 = highest).  The default is 5.

 -L <log>
	Specify the path to a log file.  By default, all output (stdout and stderr)
	goes to:
	/p4/<instance>/logs/load_checkpoint.<timestamp>.log

	NOTE: This script is self-logging.  That is, output displayed on the screen
	is simultaneously captured in the log file.  Do not run this script with
	redirection operators like '> log' or '2>&1', and do not use 'tee.'

 -si	Operate silently.  All output (stdout and stderr) is redirected to the log
	only; no output appears on the terminal.
      
 -D     Set extreme debugging verbosity.

HELP OPTIONS:
 -h	Display short help message
 -man	Display man-style help message
 -V	Dispay version info for this script and its libraries.

EXAMPLES:
	Sample non-interactive usage (bash syntax):
	nohup /load_checkpoint.sh /p4/1/checkpoints/p4_1.ckp.4025.gz -i 1 -y -si < /dev/null > /dev/null 2>&1 &

	Then, monitor with:
	tail -f $(ls -t $LOGS/load_checkpoint.*.log|head -1)
