Considerations for Configuring the Engine element
backgroundProcess
The Engine, Host, and Context elements implement the
org.apache.catalina.Container interface. One of the methods of the
interface is backgroundProcess. Each of the containers implements the
backgroundProcess method, which may implement some container functionality
and some housekeeping functions. For example, when the Host element
backgroundProcess is invoked, it checks if the auto deployer must deploy,
undeploy, or redeploy any application.
Table 3-14. Attribute List for the Engine Element
Attribute Description
Default
value
backgroundPro
cessorDelay
Represents the delay in seconds between the
invocation of the backgroundProcess method on this
engine and on its child containers, including all the hosts
and contexts. Child containers methods will not be
invoked if their delay value is not negative. This means
that the child containers are using their own processing
thread. Setting this to a positive value will cause a
thread to spawn. After waiting the specified amount of
time, the thread will invoke the backgroundProcess
method on this engine and all its child containers. If not
specified, the default value for this attribute is 10, which
represents a 10 second delay. For more information on
the backgroundProcess, see backgroundProcess
on
page 3-52.
className Represents the Java class name of the implementation
to use. This class must implement the
org.apache.catalina.Engine interface. If this
attribute is not specified, the standard value
org.apache.catalina.Core.StandardEngine
will be used.
HP recommends that you use the default value.
defaultHost The default host name, which identifies the Host that will
process requests directed to host names on this server,
but which are not defined in this configuration file.
This name must match the name attributes of one of the
Host elements nested immediately inside the Engine
element.
localhost
jvmRoute Not applicable to NSJSP.
name The logical name of this Engine, used in log and error
messages.
