Tips for backup and restore

Here are tips to make the best use of backup and restore:

• To ensure the latest gWLM data is backed up, issue the following command before using the

--backup option:

gwlm history --flush

• If the CMS or the managed nodes have been modified (such as changes in number of cores

or hostnames) between a backup and a restore or you are trying to do a restore on a different

CMS, gWLM will probably not function as expected after the restore.

Setting database recovery model

When the gWLM is created in Microsoft SQL, the recovery model is same as that of the model

database. Depending on the needs you can alter the recovery model after the creation of the

database using Transact-SQL statements. Simple Recovery model requires less space and is easier

to manage than the Full Recovery model, but at the cost of higher data loss risk if any database

file is damaged. Please consult the database vendor's guidelines before choosing an appropriate

recovery model.

Setting gWLM properties

gWLM provides two properties files that allow you to control various gWLM behaviors. One file

is for the CMS daemon or service, and the other is for use on all the managed nodes. Read the

files for information on the behaviors they control.

CMS properties

The CMS properties are in /etc/opt/gwlm/conf/gwlmcms.properties on HP-UX and in

C:\Program Files\HP\Virtual Server Environment\conf\gwlmcms.properties

on Windows. (The given Windows path is the default; however, a different path might have been

selected at installation.)

NOTE: Some values are read by gWLM only when a daemon or service is started; while other

values are read when an SRD is deployed. Refer to the file for information on when individual

properties are read.

Restarting gwlmcmsd temporarily disables HP Matrix OE visualization and HP Capacity Advisor.

The gwlmcms.properties file is shown below.

# $Date: 2008/12/02 20:17:18 $

# $Revision: 1.1 $

# 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
