Application assembly performance checklist

Application assembly tools are used to build J2EE components and modules into J2EE applications. Application assembly consists of defining application components and their attributes including enterprise beans, servlets and resource references. Many of these application configuration settings and attributes play an important role in the run-time performance of the deployed application. Use this information as a check list of important parameters and advice for finding optimal settings:

• EJB module settings
  • Entity bean settings
    • Bean Cache - Activate at
    • Bean Cache - Load at

  • Method extensions settings
    • Isolation level
    • Access intent

  • Container transactions assembly settings

• Web modules assembly settings
  • Distributable
  • Reload interval
  • Reload enabled

• Web component settings
  • Load on startup

For information about JSP compilation, see these topics in Application development:

• Pre-touch tool for compiling and loading JSP files - The JSP pre-touch tool can enhance application server performance by causing all JSP files to be compiled when your application server starts.
• JavaServer Pages (JSP) - This page includes general information about JSP files, and provides links to information about JSP batch compilation, disabling run-time compilation, and reducing JSP compile time.
