5.7 Setting the System and Logging properties
Once the installation is complete you would be configuring the different system
properties and enabling logging for the application. With Maximo Asset
Management Essentials 7.1 this task has become far easier, as it comes with
dedicated applications to perform these activities.
5.7.1 System Properties Application
System Properties is a new application that is a part of Maximo Asset
Management Essentials 7.1 and can be used to configure System-wide
properties that are at a Global level or Instance level. These Properties consist of
keys and values that determine the configuration of the product and the behavior
of many of its components.
Global Properties: A global property exists only at a system-wide level. This
means that the property is applicable to all the product server instances (for
example: application server) working with a common database. For example, the
system property mxe.logging.rootfolder is a global property whose value is a
directory on the hard disk of the server machine where the product's log files
reside.
Instance Properties: An instance property is defined and associated with a
specific product server instance. For example, you can configure the system
property mxe.crontask.donotrun to be an instance-specific property. You do this
by associating the mxe.crontask.donotrun system property with a specific server
(for example: MXServer1) and a value applicable only to that server (for example,
a value of BBCron). As a result of this configuration, the Bulletin Board cron task
(BBCron) is not executed on MXServer1, yet it can execute in another product
instance, such as MXServer2.
Each property defined in the System Properties application has a number of
characteristics that you can manage. The following table describes these
characteristics:
Property Characteristic Description
File Override Specifies if the property and its value are loaded from a file rather
than from the database.
Global Only Specifies whether this property must exist only at a system-wide
level. It implies the property cannot be overridden at the instance
level.
