Others
was_Server_provisionComponents
categorical
false
true
, false
yes
Select this property if you want the server components started as they are needed by an application that is running on this server
was_ObjectRequestBroker_noLocalCopies
categorical
false
true
, false
yes
Specifies how the ORB passes parameters. If enabled, the ORB passes parameters by reference instead of by value, to avoid making an object copy. If disabled, a copy of the parameter passes rather than the parameter object itself.
was_PMIService_statisticSet
categorical
basic
true
, false
yes
When PMI service is enabled, the monitoring of individual components can be enabled or disabled dynamically. PMI provides four predefined statistic sets that can be used to enable a set of statistics
