SYNOPSISha_gcd [ -hilV] [ -c conffile ] [ -n nodename ] [ -p portno ] [ -s loglevel ] [ -L logpath ]
DESCRIPTION
The Group Communication Daemon (ha_gcd) provides an atomic messaging
service in a highly available cluster. This daemon is layered on top of
the Cluster Membership Services Daemon (ha_cmsd), which presents a
consistent view of node membership in the presence of node and network
failures. The ha_gcd presents a consistent view of group memberships in
the presence of process failures and changing node memberships.
OPTIONS
The ha_gcd takes several options:
-h Display help message regarding ha_gcd options.
-i Run in independent mode: do not talk to ha_cmsd.
-l Run ha_gcd as a foreground process.
-V Output the version of this ha_gcd.
-c conffile Read ha_gcd configuration from conffile database.
-n nodename The nodename used by the ha_gcd process to connect to the
ha_cmsd, ha_srmd and ha_fsd processes. This option can be
used to run multiple ha_gcd processes on a machine. The
nodename argument corresponds to the virtual nodename used by
each ha_gcd process.
-p portno Set port number used by ha_gcd for inter ha_gcd communication
to portno.
-s loglevel Set the log level of the messages logged to stderr to
loglevel.
-L logpath Set the log directory used by ha_gcd to log messages to
logpath.
