WebSphere Application Server V7.0: Concepts ... - IBM Redbooks

Consider whether to use automatic synchronization to push out changes to the
nodes or to synchronize changes manually. In an environment where there are a
lot of administration changes going on, automatic synchronization might have a
performance impact on the network.
9.5.2 Configuring application and application server startup
behaviors
One feature of WebSphere Application Server is the ability to manage the startup
of applications and application servers. By default, applications start when their
server starts.
The following settings enable you to fine-tune the startup speed and order of
applications that are configured to start automatically when the server starts.
► Startup order setting
The Startup order setting for an application lets you specify the order in which
to start applications when the server starts. The application with the lowest
startup order starts first. Applications with the same startup order start in
parallel. This can be important for applications that have been split into
sub-applications that need to start in a certain order due to dependencies
between them.
► Launch application before server completes startup setting
The Launch application before server completes startup setting lets you
specify whether an application must initialize fully before its server is
considered started. Background applications can be initialized on an
independent thread, thus allowing the server startup to complete without
waiting for the application.
► Create MBeans for resources setting
The Create MBeans for resources setting specifies whether to create MBeans
for resources such as servlets or JavaServer Pages (JSP) files within an
application when the application starts.
Access these settings in the Integrated Solutions Console by navigating to
Applications → Application Types → WebSphere enterprise applications →
→ Startup behavior.
The Parallel start setting for an WebSphere Application Server lets you specify
whether to have the server components, services, and applications in an
application server start in parallel rather than sequentially. This can shorten the
startup time for a server.
