Data Storage Considerations
...
To better manage the storage and performance requirements of the raw event and aggregate event data sets these can be moved into their own databases. To configure separate JDBC connection information for these data sets edit uportal-war/src/main/resources/properties/rdbm.properties and change the RawEvents and AggrEvents database configuration. After doing this either ant initdb or
After modifying the rdbm.properties file to store the events to a different database, perform either of the following:
ant initdb(BEWARE: performing this command will re-initialize your entire database, use with caution. )ant db-hibernate-raw-events
...
- and/or
ant db-hibernate-aggr-events
...

##### uPortal Raw Events DB
RawEventsJdbcDriver=${environment.build.hibernate.connection.driver_class}
RawEventsJdbcUrl=${environment.build.hibernate.connection.url}
RawEventsJdbcUser=${environment.build.hibernate.connection.username}
RawEventsJdbcPassword=${environment.build.hibernate.connection.password}
##### uPortal Aggregate Events DB
AggrEventsJdbcDriver=${environment.build.hibernate.connection.driver_class}
AggrEventsJdbcUrl=${environment.build.hibernate.connection.url}
AggrEventsJdbcUser=${environment.build.hibernate.connection.username}
AggrEventsJdbcPassword=${environment.build.hibernate.connection.password} |

The default configuration results in all PortalEvents being persisted to the RawEvents database. To exclude certain events, filters can be configured in the listenerEventFilters list in uportal-war/src/main/resources/properties/contexts/eventHandlerContext.xml. There is provided support for filtering events by type and by the user the event was generated for.
Purging Persistent Events
The Event Aggregation process also handles purging of aggregated events. The default configuration is to purge raw event data 1 hour after it has been aggregated. This window size can be changed by setting the org.jasig.portal.events.aggr.PortalEventPurgerImpl.purgeDelay property in uportal-war/src/main/resources/properties/portal.properties
