-# 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.
