On-demand Deployment of Internal Applications Use FastSwap Deployment to Minimize Redeployment Time Generic Overrides
7.3 Deployment
The following sections provide information on how to improve deployment performance: ■ Section 7.3.1, On-demand Deployment of Internal Applications ■ Section 7.3.2, Use FastSwap Deployment to Minimize Redeployment Time ■ Section 7.3.3, Generic Overrides7.3.1 On-demand Deployment of Internal Applications
WebLogic Server deploys many internal applications during startup. Many of these internal applications are not needed by every user. You can configure WebLogic Server to wait and deploy these applications on the first access on-demand instead of always deploying them during server startup. This can conserve memory and CPU time during deployment as well as improving startup time and decreasing the base memory footprint for the server. WebLogic Server deploys many internal applications during startup. Many of these internal applications are not needed by every user. You can configure WebLogic Server to wait and deploy these applications on the first access on-demand instead of always deploying them during server startup. This can conserve memory and CPU time during deployment as well as improving startup time and decreasing the base memory footprint for the server.For a development domain, the default is for WLS to deploy internal applications on-demand. For a production-mode domain, the default is for WLS to deploy internal applications as part of server startup. For more information on how to use and configure this feature, see On-demand Deployment of Internal Applications in Deploying Applications to WebLogic Server.7.3.2 Use FastSwap Deployment to Minimize Redeployment Time
In deployment mode, you can set WebLogic Server to redefine Java classes in-place without reloading the ClassLoader. This means that you do not have to wait for an application to redeploy and then navigate back to wherever you were in the Web page flow. Instead, you can make your changes, auto compile, and then see the effects immediately. For more information on how to use and configure this feature, see Using FastSwap Deployment to Minimize Redeployment in Deploying Applications to WebLogic Server.7.3.3 Generic Overrides
Generic overrides allow you to override application specific property files without having to crack a jar file by placing application specific files to be overridden into the AppFileOverrides optional subdirectory. For more information on how to use and configure this feature, see Generic File Loading Overrides in Deploying Applications to WebLogic Server.7.4 Thread Management
