USAGE for load_checkpoint.sh v2.3.5:
load_checkpoint.sh <checkpoint> [-i <instance>] [-s <ServerID>] [-c] [-l] [-r] [-b] [-y] [-L <log>] [-si] [-v<n>] [-D]
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
* 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,
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:
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.
Specify the SDP instance. This can be omitted if SDP_INSTANCE is already
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
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
-v<n> Set verbosity 1-5 (-v1 = quiet, -v5 = highest). The default is 5.
Specify the path to a log file. By default, all output (stdout and stderr)
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.
-h Display short help message
-man Display man-style help message
-V Dispay version info for this script and its libraries.
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)
