# The P4INSTANCE value is intended to uniquely identify
# a given set of Perforce databases within your enterprise.
#
# By default, P4INSTANCE is a simple integer value, e.g.
# '1'.  This drives many other values related to that
# instance, such as where databases and checkpoints are
# stored.  For example, P4ROOT for instance 1 is,
# /p4/1/root.
#
# Use the 'case' block to define a P4PORT value for each
# P4INSTANCE where one or more of the following are true:
# * You wish to use a tag name rather than the default of
#   a purely numeric value for P4INSTANCE value.  (A short
#   tag name is recommended, e.g. 'ops'.)
# * You will use the "ssl:" or other prefix,
# * You need to specify the hostname component of P4PORT even
#   locally here on the server, as is necessary with some
#   multiple network interface card configurations, and/or
# * You simply don't want to use the numeric calculation of
#   P4PORT based on an instance number.
#
# If you use named rather than numbered instances, you must
# provide appropriate numeric values for the various
# *PORT settings for services you wish to use, such as
# P4PORT, P4WEBPORT, P4FTPPORT, etc.  The 'abc' and 'sec'
# values in the 'case' bloc below are samples.  Replace
# them with the desired values for your given instance name.

# Leave SSL_PREFIX empty here.  Set the value to "ssl:"
# in the case block below for any instances using SSL.

# needed in the case block below.  P4BROKERPORTNUM is
# numeric portion of the P4PORT value used to reference
# the broker.

# Leave P4MASTERPORTNUM empty here. P4MASTERPORTNUM is
# the numeric portion of the port number used of the
# P4PORT value used by the replica to access the master
# server.  Often this is the same as the P4PORTNUM
# value defined below, but it can differ in some cases.
# For example, if the P4PORT value defined on the master
# uses the 'localhost:' prefix and replicas access the
# master via a broker P4MASTERPORTNUM will be set to
# $P4BROKERPORTNUM for that instance.
