# Change the first three variables below to match the volume names on the machine
# you are configuring the SDP on. 
# Set the remaining variables appropriately. The meaning of each should be obvious.
#
# In the SDP variable below, the sdp directory needs to contain the contents of:
# //depot/intranet/consulting/sw/MAIN/sdp
#
# Run this script as root, and pass in the instance number you are configuring.
# If you do not have root access, then remove the ID section and all the chown
# commands at the end of the script. You will need to have the $P4DIR directory created
# by the root user and the ownership changed to the OS user that you are planning
# to run Perforce under. The Metadata, Depotdata and Logs volumes will also need
# to be owned by the OS user as well in order for the script to work. You can then
# run this script as the OS user for Perforce and everything should work fine.
#
# This script creates an init script in the $P4DIR/$INSTANCE/bin directory. You can use
# it from there if you are configuring a cluster, or you can link it in /etc/init.d
# if you are setting up a stand alone machine.
#
# After running this script, you also need to set up the crontab based on files
# in $P4DIR/common/etc/cron.d.  For convenience, crontab files are copied to 
# $P4DIR/p4.crontab and $P4DIR/p4.crontab.replica.
#
# Now, put the license file in place and launch the server with the init script.
#
# Then run $P4DIR/common/bin/p4master_run <instance> $P4DIR/common/bin/live_checkpoint.sh
# and then run both the daily_backup.sh and weekly_backup.sh to make sure everything is
# working before setting up the crontab.
#
# Also run $P4DIR/common/bin/p4master_run <instance> $P4DIR/common/bin/p4review.py <instance>
# to make sure the review script is working properly.
#
# UPGRADING SDP
# Specify the -test parameter to the script.
# In this case the script will NOT make the various directories under $P4DIR, but will instead
# create /tmp/p4 directory structure with the various files processed via templates etc.
# You can then manually compare this directory structure with your existing $P4DIR structure
# and manually copy the various files into it.
