# Description: Service script for starting/stopping/monitoring \
# Sybase Adaptive Server on: \
# Red Hat Enterprise Linux 5 ES \
# Red Hat Enterprise Linux 5 AS
#
# NOTES:
#
# (1) Before running this script, we assume that user has installed
# Sybase ASE 15.0.2 or higher version on the machine. Please
# customize your configuration in /etc/cluster/cluster.conf according
# to your actual environment. We assume the following files exist before
# you start the service:
# /$sybase_home/SYBASE.sh
# /$sybase_home/$sybase_ase/install/RUN_$server_name
#
# (2) You can customize the interval value in the meta-data section if needed:
# <action name="start" timeout="300" />
# <action name="stop" timeout="300" />
#
# <!-- Checks to see if it''s mounted in the right place -->
# <action name="status" interval="30" timeout="100" />
# <action name="monitor" interval="30" timeout="100" />
#
# <!--Checks to see if we can read from the mountpoint -->
# <action name="status" depth="10" timeout="100" interval="120" />
# <action name="monitor" depth="10" timeout="100" interval="120" />
#
# <action name="meta-data" timeout="5" />
# <action name="validate-all" timeout="5" />
# The timeout value is not supported by Redhat in RHCS5.0.
#
# (3) This script should be put under /usr/share/cluster. Its owner should be "root" with
# execution permission.
