instance_vars.template #50

#------------------------------------------------------------------------------
# Instance specific variables are set or calculated in this file. This file
# is not intended to be sourced directly. It is sourced when the main SDP
# environment file, /p4/common/bin/p4_vars, is sourced. This p4_N.vars file
# is sourced as in the following example, where N is teh SDP instance name,
# with a value of 1 by default:
#
#   source /p4/common/bin/p4_vars N
#
# A line like the above can optionally be added in the ~/.bashrc file
# of the perforce user on the Linux system. This is recommended so that
# the SDP Environment is loaded properly during initial login.
#
#------------------------------------------------------------------------------
# When editing values in this file keep in mind the following:
#
# * Do not change values for which the comments say 'DO NOT CHANGE'.
# * Do not add code or logic of any kind.
# * Limit changes strictly to change the right-side of assignments (i.e. text
# to the right of the '=' sign).
# * Be careful not to introduce whitespace characters on either side of
# the '=' sign.
#
# If custom logic is needed, e.g. to add host-specific behaviors or configure
# multipe active brokers with different ports, add that custom logic in custom
# local files that appear in the /p4/common/site directory.  Files in the
# 'site' directory will not be not affected by SDP upgrades. Also, files in the
# 'site' directory are inherently custom and not officially supported by
# Perforce Technical Support.
#
# If needed, custom logic goes into these files:
# * /p4/common/site/config/p4_vars.local    - Global/Common
# * /p4/common/site/config/p4_N.vars.local  - Instance-specifc (N=instance).
#
# This file contains comments of the form: # shellcheck disable=SCNNNN.
# DO NOT CHANGE OR MOVE THESE COMMENT LINES.

# in (from p4_vars) rather than executed as a script.

# replay options with 'p4d -jcp', 'p4d -jdp', and 'p4d -jrp',
# respetively.
#
# If parallel checkpoints are enabled:
# * The live_checkpoint.sh will create live checkpoints using 'p4d -jcp', and

# * The daily_checkpoint.sh will create offline checkpoints using 'p4d -jdp',
#   and replay using 'p4d -jrp'.
# * The recover_offline_db.sh will look for checkpoint directories rather
#   than singular checkpoint files, and replay with 'p4d -jrp'.
# * The refresh_P4ROOT_from_offline_db.sh replays using 'p4d -jrp'.
#
# The db.checkpoint.threads configurable is ignored with the scripts, as
