This section describes steps that are common to all Web application servers. These
steps are required to perform the Web application server-specific configuration steps
that are described later in this document.
Event Generation Framework
The Event Generation Framework Web application is packaged in the SAS BI
Dashboard EAR file. The SAS BI Dashboard Web application can be clustered, but
the Event Generation Framework cannot be clustered. The events generated by the
framework must be generated by a single instance of the framework so that the
events are generated for a single target. You can keep the applications in the same
EAR file and provide high availability with a hot and cold standby strategy, or use
high availability software to run one active instance of both SAS BI Dashboard and
the Event Generation Framework.
However, if SAS BI Dashboard receives a lot of use and multiple instances are
needed, then there is another option. You can separate the event generation
framework WAR file from the SAS BI Dashboard EAR file and then deploy a single
instance of the framework on a stand-alone server, but deploy multiple instances of
SAS BI Dashboard to the cluster. This strategy is used throughout the rest of this
document.
The following steps describe the option of extracting the framework WAR file and
then modifying the SAS BI Dashboard EAR file. When these steps are complete, the
framework can be deployed to a stand-alone server, and the SAS BI Dashboard
EAR file can be deployed to the cluster. To ensure high availability, consider using a
