gWLM 提供的两个属性文件可以控制各种 gWLM 行为。其中一个文件用于 CMS 守护程序或服务,另一个文件在所有受管节点中使用。查看这两个文件,可获得有关它们控制的行为的信息。

CMS 属性

CMS 属性位于 HP-UX 上的 /etc/opt/gwlm/conf/gwlmcms.properties 以及 Windows 上的 C:\Program Files\HP\Virtual Server Environment\conf\gwlmcms.properties 中(给出的 Windows 路径是缺省值;但是,您可以在安装时选择其他路径)。

注释:在启动守护程序或服务时,gWLM 仅读取一部分值;其他值将在部署 SRD 时读取。有关何时读取各个属性的信息,请参考该文件。

临时重新启动 gwlmcmsd 将禁用 HP Virtualization Manager 和 HP Capacity Advisor。

gwlmcms.properties 文件如下所示。

#
# Contents:
#	This file contains the default configuration values for the
#	Global Workload Manager CMS.
#
#	You must restart gwlmcmsd for changes made to this file
#	to take effect--unless otherwise noted.
#

#
# Set FileHandler log level for the following log files:
#       /var/opt/gwlm/gwlmcmsd.log.0
#       /var/opt/gwlm/gwlmcommand.log.0
#       /var/opt/gwlm/gwlm.log.0
#       /var/opt/vse/logs/gwlminitconfig.log.0
# Valid levels, from most severe to least, are:
#    SEVERE
#    WARNING
#    INFO
#    CONFIG
#    FINE
#    FINER
#    FINEST
# When you set the level, you will see messages only from that level and
# the levels that are more severe.So, the SEVERE level produces the fewest
# messages, while the FINEST level includes messages from all seven levels.
#
com.hp.gwlm.util.Log.logLevel = INFO

#
# Specify the size (in MB) and number of files to use  
# for logging.For a single file of unlimited size, set
# logFileSize to negative one (logFileSize=-1).
# Otherwise, total log file size is
#    logFileSize * logNFiles
#
com.hp.gwlm.util.Log.logFileSize = 20
com.hp.gwlm.util.Log.logNFiles = 3

#
# Support for automatic database statistics gathering.These properties
# control how often row-level statistics are gathered from the database in
# order to optimize performance.
#
#   com.hp.gwlm.cms.db.analyze.time:
#       Frequency, in minutes, in which statistics are gathered.The
#       default is to attempt to gather database statistics every 60
#       minutes.When the analysis runs, statistics will only be gathered
#       if a certain number of transactions  have been processed (which is
#       configured in the property below).
#
#   com.hp.gwlm.cms.db.analyze.limit:
#       Number of consecutive transactions that must take place before a
#       database analysis is performed.
#
com.hp.gwlm.cms.db.analyze.time  = 60
com.hp.gwlm.cms.db.analyze.limit = 50

#
# Support for the database cache on the CMS.
#
#  cachesize:
#	The number of historical configurations to cache in memory.
#	A larger historical configuration cache reduces time spent
#	in database lookups.The valid range is 1-1000.
#
com.hp.gwlm.cms.cachesize = 100

#
# Support for local data caching on a remote node for report generation.
# These properties are defined on the CMS but are pushed out to the remote
# node managers during deployment of an SRD.The cached objects on the
# agent consume an amount of memory approximated by:
#
#  Memory = 5000 * workloads * cachesize * (60 / resource_domain_interval)
#
# bytes of memory.For example, if there are 4 workloads deployed with a
# 15 second interval and a cachesize of 20 minutes, the agent will need:
#
#   Memory = 5000 * 4 * 20 * (60 / 15) ~ 2.5 MB.
#
#  cachesize:
#    The number of minutes of real-time data to maintain on the remote
#	node for future CMS access.This value must be at least three
#	times the 'samples' value specified below.The default value is
#    20 minutes.
#
#  samples:
#	The number of minutes of real-time data used to aggregate into a
#	historical data point.The default is to aggregate the data into
#	5-minute averages.
#
com.hp.gwlm.node.cachesize = 20
com.hp.gwlm.node.samples   = 5

#
# Support for real-time graphing properties.
#
#  viewport:
#    The size of the displayed real-time graph (in minutes).
#
#  refresh:
#    The refresh rate of the real-time graphs and tables (in seconds).
#
com.hp.gwlm.ui.monitor.viewport = 20
com.hp.gwlm.ui.monitor.refresh  = 15

代理属性

代理属性位于 HP-UX 上的 /etc/opt/gwlm/conf/gwlmagent.properties 以及 Windows 上的 C:\Program Files\HP\Virtual Server Environment\conf\gwlmagent.properties 中(给出的 Windows 路径是缺省值;但是,您可以在安装时选择其他路径)。

注释:您必须在已修改属性文件的各个受管节点上重新启动 gwlmagent 守护程序,才能使对该文件的更改生效。

gwlmagent.properties 文件如下所示。

# $Date: 2008/02/01 19:00:32 $
# $Revision: 1.28 $
#
# Contents:
#	This file contains the default configuration values for the
#	Global Workload Manager Agent on a given managed node.The
#	agent on each managed node uses the default values unless you
#	edit that node's gwlmagent.properties file.
#
#	You must restart gwlmagent for changes made to this file to
#	take effect.
#

#
# Set FileHandler /var/opt/gwlm/gwlmagent.log.0 log level.
# Valid levels, from most severe to least, are:
#	SEVERE
#	WARNING
#	INFO
#	CONFIG
#	FINE
#	FINER
#	FINEST
# When you set the level, you will see messages only from that level and
# the levels that are more severe.So, the SEVERE level produces the fewest
# messages, while the FINEST level includes messages from all seven levels.
#
com.hp.gwlm.util.Log.logLevel = INFO

#
# Specify the size (in MB) and number of files to use  
# for logging.For a single file of unlimited size, set
# logFileSize to negative one (logFileSize=-1).
# Otherwise, total log file size is
#    logFileSize * logNFiles
#
com.hp.gwlm.util.Log.logFileSize = 20
com.hp.gwlm.util.Log.logNFiles = 3

#
# Set the number of seconds for the high availability (HA) minimum
# timeout.Communication is considered lost on a managed node
# once the timeout period has elapsed.
#
# By default, communication is not considered lost until 10 allocation
# intervals have elapsed without communication.The default value of the
# property (60) is used only when the allocation interval is less than 6
# seconds.  
#
com.hp.gwlm.node.HA.minimumTimeout = 60

#
# Enable/disable use of Instant Capacity (iCAP) to simulate movement of
# cores across nPartitions.To use iCAP, you must enable this property on 
# each managed nPartition where you want to take advantage of iCAP.Also, 
# each nPartition must meet the requirements outlined in the online help 
# topic "Getting the most out of gWLM" as well as in the section "USING 
# NPARS AS COMPARTMENTS IN AN SRD" in the gwlmxml(4) man page on HP-UX or 
# the gwlmxml(5) man page on Linux.
#
com.hp.gwlm.platform.icap.manageWithIcap = on

#
# Set the minimum number of Temporary Instant Capacity (TiCAP) minutes
# that must be available for TiCAP activation.  gWLM will stop using
# TiCAP when the available balance goes below this threshold.The
# same value should be set on all agents managing the SRD.To use
# TiCAP, it must be available on the complex and enabled at the policy
# level or the SRD level.
#
com.hp.gwlm.node.ticap.minimumBalance = 30

通信端口

gWLM 使用下列通信端口:

受管节点:9617

CMS:9618

如果需要更改这些端口,请将下列行:

com.hp.gwlm.cms.port = 端口 X

com.hp.gwlm.node.port = 端口 Y

添加到下面两个属性文件:

  • gwlmcms.properties

    在 HP-UX 上,该文件位于 /etc/opt/gwlm/conf/ 中。在 Windows 上,该文件位于 C:\Program Files\HP\Virtual Server Environment\conf\ 中(给出的 Windows 路径是缺省值;但是,您可以在安装时选择其他路径)。

  • /etc/opt/gwlm/conf/gwlmagent.properties

其中端口 X端口 Y 的值不能相同。

在所有受管节点以及 CMS 上的所有属性文件中,com.hp.gwlm.cms.port 属性必须具有相同的端口 X 值。同样,在所有受管节点以及 CMS 上的所有属性文件中,com.hp.gwlm.node.port 属性必须具有相同的端口 Y 值。

必须重新启动 gwlmcmsdgwlmagent,才能使更改生效。如果正在通过 HP SIM 使用 gWLM,则必须同时重新启动 SIM。(在 HP-UX 上,可使用 /opt/mx/bin/mxstopmxstart 重新启动 SIM 守护程序。在 Windows 上,请重新启动 HP Systems Insight Manager 服务)。

注释:临时重新启动 gwlmcmsd 将禁用 HP Virtualization Manager 和 HP Capacity Advisor。
