B、应用级别的ORACLE程序包配置
B-1: 创建程序包配置模板, 编辑这些模板文件，以指定程序包名称、按优先级排序的节点列表、控制脚本的位置以及各个程序包的故障切换参数。
# mkdir /dev/cmcluster/pkg1
# cmmakepkg –p /etc/cmcluster/pkg1/pkg1.conf
#vi /etc/cmcluser/pkg1/pkg1.conf

# ********************************************************************** *******
# ****** HIGH AVAILABILITY PACKAGE CONFIGURATION FILE (template)
# *********************************************************************** *******
# ******* Note: This file MUST be edited before it can be used.
# * For complete details about package parameters and how to set them, *
# * consult the Serviceguard Extension for RAC manuals.
# ******************************************************************************
# Enter a name for this package. This name will be used to identify the
# package when viewing or manipulating it. It must be different from
# the other configured package names.
PACKAGE_NAME pkg1 （程序包的名字）
# Enter the package type for this package. PACKAGE_TYPE indicates
# whether this package is to run as a FAILOVER or SYSTEM_MULTI_NODE
# package.
#
# FAILOVER package runs on one node at a time and if a failure
# occurs it can switch to an alternate node.
#
# SYSTEM_MULTI_NODE
# package runs on multiple nodes at the same time.
# It can not be started and halted on individual nodes.
# Both NODE_FAIL_FAST_ENABLED and AUTO_RUN must be set
# to YES for this type of package. All SERVICES must
# have SERVICE_FAIL_FAST_ENABLED set to YES.
#
# NOTE: Packages which have a PACKAGE_TYPE of SYSTEM_MULTI_NODE are
# not failover packages and should only be used for applications
# provided by Hewlett-Packard.
#
# Since SYSTEM_MULTI_NODE packages run on multiple nodes at
# one time, following parameters are ignored:
#
# FAILOVER_POLICY
# FAILBACK_POLICY
#
# Since an IP address can not be assigned to more than node at a
# time, relocatable IP addresses can not be assigned in the
# package control script for multiple node packages. If
# volume groups are assigned to multiple node packages they must
# activated in a shared mode and data integrity is left to the
# application. Shared access requires a shared volume manager.
#
#
# Examples : PACKAGE_TYPE FAILOVER (default)
# PACKAGE_TYPE SYSTEM_MULTI_NODE
#
PACKAGE_TYPE FAILOVER（默认数值，不需更改）
# Enter the failover policy for this package. This policy will be used
# to select an adoptive node whenever the package needs to be started.
# The default policy unless otherwise specified is CONFIGURED_NODE.
# This policy will select nodes in priority order from the list of
# NODE_NAME entries specified below.
#
# The alternative policy is MIN_PACKAGE_NODE. This policy will select
# the node, from the list of NODE_NAME entries below, which is
# running the least number of packages at the time this package needs
# to start.
FAILOVER_POLICY CONFIGURED_NODE（默认数值，不需更改）
# Enter the failback policy for this package. This policy will be used
# to determine what action to take when a package is not running on
# its primary node and its primary node is capable of running the
# package. The default policy unless otherwise specified is MANUAL.
# The MANUAL policy means no attempt will be made to move the package
# back to its primary node when it is running on an adoptive node.
#
# The alternative policy is AUTOMATIC. This policy will attempt to
# move the package back to its primary node whenever the primary node
# is capable of running the package.
FAILBACK_POLICY MANUAL（默认数值，不需更改）
# Enter the names of the nodes configured for this package. Repeat
# this line as necessary for additional adoptive nodes.
#
# NOTE: The order is relevant.
# Put the second Adoptive Node after the first one.
#
# Example : NODE_NAME original_node
# NODE_NAME adoptive_node
#
# If all nodes in the cluster are to be specified and order is not
# important, "NODE_NAME *" may be specified.
#
# Example : NODE_NAME *
NODE_NAME hp1 （节点1名字）
NODE_NAME hp2 （节点2名字）
# Enter the value for AUTO_RUN. Possible values are YES and NO.
# The default for AUTO_RUN is YES. When the cluster is started the
# package will be automatically started. In the event of a failure the
# package will be started on an adoptive node. Adjust as necessary.
#
# AUTO_RUN replaces obsolete PKG_SWITCHING_ENABLED.
AUTO_RUN YES（默认参数，不要更改）
# Enter the value for LOCAL_LAN_FAILOVER_ALLOWED.
# Possible values are YES and NO.
# The default for LOCAL_LAN_FAILOVER_ALLOWED is YES. In the event of a
# failure, this permits the cluster software to switch LANs locally
# (transfer to a standby LAN card). Adjust as necessary.
#
# LOCAL_LAN_FAILOVER_ALLOWED replaces obsolete NET_SWITCHING_ENABLED.
LOCAL_LAN_FAILOVER_ALLOWED YES （默认参数，不要更改）
# Enter the value for NODE_FAIL_FAST_ENABLED.
# Possible values are YES and NO.
# The default for NODE_FAIL_FAST_ENABLED is NO. If set to YES,
# in the event of a failure, the cluster software will halt the node
# on which the package is running. All SYSTEM_MULTI_NODE packages must have
# NODE_FAIL_FAST_ENABLED set to YES. Adjust as necessary.
NODE_FAIL_FAST_ENABLED NO （默认参数，不要更改）
# Enter the complete path for the run and halt scripts. In most cases
# the run script and halt script specified here will be the same script,
# the package control script generated by the cmmakepkg command. This
# control script handles the run(ning) and halt(ing) of the package.
# Enter the timeout, specified in seconds, for the run and halt scripts.
# If the script has not completed by the specified timeout value,
# it will be terminated. The default for each script timeout is
# NO_TIMEOUT. Adjust the timeouts as necessary to permit full
# execution of each script.
# Note: The HALT_SCRIPT_TIMEOUT should be greater than the sum of
# all SERVICE_HALT_TIMEOUT values specified for all services.
RUN_SCRIPT /etc/cmcluster/pkg1/pkg1.cntl
RUN_SCRIPT_TIMEOUT NO_TIMEOUT
HALT_SCRIPT /etc/cmcluster/pkg1/pkg1.cntl
HALT_SCRIPT_TIMEOUT NO_TIMEOUT
这里请注意，在ORACLE还未安装时，我们如何用脚本来验证集群是否安装完毕呢，我们可以编译一条语句放在脚本里 如“echo hello”就行了。

# Enter the names of the storage groups configured for this package.
# Repeat this line as necessary for additional storage groups.
#
# Storage groups are only used with CVM disk groups. Neither
# VxVM disk groups or LVM volume groups should be listed here.
# By specifying a CVM disk group with the STORAGE_GROUP keyword
# this package will not run until the VxVM-CVM-pkg package is
# running and thus the CVM shared disk groups are ready for
# activation.
#
# NOTE: Should only be used by applications provided by
# Hewlett-Packard.
#
# Example : STORAGE_GROUP dg01
# STORAGE_GROUP dg02
# STORAGE_GROUP dg03
# STORAGE_GROUP dg04
#
# Enter the SERVICE_NAME, the SERVICE_FAIL_FAST_ENABLED and the
# SERVICE_HALT_TIMEOUT values for this package. Repeat these
# three lines as necessary for additional service names. All
# service names MUST correspond to the SERVICE_NAME[] entries in
# the package control script.
#
# The value for SERVICE_FAIL_FAST_ENABLED can be either YES or
# NO. If set to YES, in the event of a service failure, the
# cluster software will halt the node on which the service is
# running. If SERVICE_FAIL_FAST_ENABLED is not specified, the
# default will be NO.
#
# SERVICE_HALT_TIMEOUT is represented as a number of seconds.
# This timeout is used to determine the length of time (in
# seconds) the cluster software will wait for the service to
# halt before a SIGKILL signal is sent to force the termination
# of the service. In the event of a service halt, the cluster
# software will first send a SIGTERM signal to terminate the
# service. If the service does not halt, after waiting for the
# specified SERVICE_HALT_TIMEOUT, the cluster software will send
# out the SIGKILL signal to the service to force its termination.
# This timeout value should be large enough to allow all cleanup
# processes associated with the service to complete. If the
# SERVICE_HALT_TIMEOUT is not specified, a zero timeout will be
# assumed, meaning the cluster software will not wait at all
# before sending the SIGKILL signal to halt the service.
#
# Example: SERVICE_NAME DB_SERVICE
# SERVICE_FAIL_FAST_ENABLED NO
# SERVICE_HALT_TIMEOUT 300
#
# To configure a service, uncomment the following lines and
# fill in the values for all of the keywords.
#SERVICE_NAME dbservice
#SERVICE_FAIL_FAST_ENABLED NO
#SERVICE_HALT_TIMEOUT 300
#注意:名字一定要和后面的/etc/cmcluster/pkg1/control.sh文件的名字吻合，一般无需配置
# Enter the network subnet name that is to be monitored for this package.
# Repeat this line as necessary for additional subnet names. If any of
# the subnets defined goes down, the package will be switched to another
# node that is configured for this package and has all the defined subnets
# available.
#SERVICE_FAIL_FAST_ENABLED NO
#SERVICE_HALT_TIMEOUT 300

# The keywords RESOURCE_NAME, RESOURCE_POLLING_INTERVAL,
# RESOURCE_START, and RESOURCE_UP_VALUE are used to specify Package
# Resource Dependencies. To define a package Resource Dependency, a
# RESOURCE_NAME line with a fully qualified resource path name, and
# one or more RESOURCE_UP_VALUE lines are required. The
# RESOURCE_POLLING_INTERVAL and the RESOURCE_START are optional.
#
# The RESOURCE_POLLING_INTERVAL indicates how often, in seconds, the
# resource is to be monitored. It will be defaulted to 60 seconds if
# RESOURCE_POLLING_INTERVAL is not specified.
#
# The RESOURCE_START option can be set to either AUTOMATIC or DEFERRED.
# The default setting for RESOURCE_START is AUTOMATIC. If AUTOMATIC
# is specified, Serviceguard will start up resource monitoring for
# these AUTOMATIC resources automatically when the node starts up.
# If DEFERRED is selected, Serviceguard will not attempt to start
# resource monitoring for these resources during node start up. User
# should specify all the DEFERRED resources in the package run script
# so that these DEFERRED resources will be started up from the package
# run script during package run time.
#
# RESOURCE_UP_VALUE requires an operator and a value. This defines
# the resource 'UP' condition. The operators are =, !=, >, =,
# and Values can be string or
# numeric. If the type is string, then only = and != are valid
# operators. If the string contains whitespace, it must be enclosed
# in quotes. String values are case sensitive. For example,
#
# Resource is up when its value is
# --------------------------------
# RESOURCE_UP_VALUE = UP "UP"
# RESOURCE_UP_VALUE != DOWN Any value except "DOWN"
# RESOURCE_UP_VALUE = "On Course" "On Course"
#
# If the type is numeric, then it can specify a threshold, or a range to
# define a resource up condition. If it is a threshold, then any operator
# may be used. If a range is to be specified, then only > or >= may be used
# for the first operator, and only
# For example,
# Resource is up when its value is
# --------------------------------
# RESOURCE_UP_VALUE = 5 5 (threshold)
# RESOURCE_UP_VALUE > 5.1 greater than 5.1 (threshold)
# RESOURCE_UP_VALUE > -5 and between -5 and 10 (range)
#
# Note that "and" is required between the lower limit and upper limit
# when specifying a range. The upper limit must be greater than the lower
# limit. If RESOURCE_UP_VALUE is repeated within a RESOURCE_NAME block, then
# they are inclusively OR'd together. Package Resource Dependencies may be
# defined by repeating the entire RESOURCE_NAME block.
#
# Example : RESOURCE_NAME /net/interfaces/lan/status/lan0
# RESOURCE_POLLING_INTERVAL 120
# RESOURCE_START AUTOMATIC
# RESOURCE_UP_VALUE = RUNNING
# RESOURCE_UP_VALUE = ONLINE
#
# Means that the value of resource /net/interfaces/lan/status/lan0
# will be checked every 120 seconds, and is considered to
# be 'up' when its value is "RUNNING" or "ONLINE".
#
# Uncomment the following lines to specify Package Resource Dependencies.
#
#RESOURCE_NAME
#RESOURCE_POLLING_INTERVAL
#RESOURCE_START
#RESOURCE_UP_VALUE [and ]
# Access Control Policy Parameters.
#
# Three entries set the access control policy for the package:
# First line must be USER_NAME, second USER_HOST, and third USER_ROLE.
# Enter a value after each.
#
# 1. USER_NAME can either be ANY_USER, or a maximum of
# 8 login names from the /etc/passwd file on user host.
# 2. USER_HOST is where the user can issue Serviceguard commands.
# If using Serviceguard Manager, it is the COM server.
# Choose one of these three values: ANY_SERVICEGUARD_NODE, or
# (any) CLUSTER_MEMBER_NODE, or a specific node. For node,
# use the official hostname from domain name server, and not
# an IP addresses or fully qualified name.
# 3. USER_ROLE must be PACKAGE_ADMIN. This role grants permission
# to MONITOR, plus for administrative commands for the package.
#
# These policies do not effect root users. Access Policies here
# should not conflict with policies defined in the cluster configuration file.
#
# Example: to configure a role for user john from node noir to
# administer the package, enter:
# USER_NAME john
# USER_HOST noir
# USER_ROLE PACKAGE_ADMIN
