Chapter 10. Other configuration options 197 System property types The two types of system properties are: Global This property exists only at a system- wide level, which means that the property is applicable to all product server instances ( such as an 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 This 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, but it can execute in another product instance, such as MXServer2. 10.5.1 Security levels This characteristic determines whether this property can be retrieved before establishing an authenticated connection to the product. The three levels of security are: PUBLIC The property and its value are accessed by unauthenticated client sessions. SECURE The property and its value are accessed by authenticated client sessions. PRIVATE The property and its value are accessed only within the product business object framework. Note: If a maximo. properties file exists and contains the same property name but a different value than the database is aware of, the value maintained in the database will be overridden by the settings in maximo. properties file.
