Weblogic Application Server FAQs

91. Can I generate deployment descriptor files automatically?
Yes, WebLogic Builder automatically generates deployment descriptor files for your J2EE applications. See WebLogic Builder Online Help.
92.Can I set the deployment order for application modules? For standalone modules?
The Load Order attribute controls the deployment order of standalone modules and applications relative to other modules and applications of the same type.

For example, standalone EJBs with smaller Load Order values are deployed before those with higher values.

Modules that are deployed as part of an Enterprise Application (EAR file or directory) are deployed in the order in which they are specified in the application.xml deployment descriptor.
93.What is the difference between the WL_HOME/config/examples/applications folder and the WL_HOME/config/examples/stage folder?
The applications folder is intended for applications that are not yet ready for a production environment. WebLogic Server dynamically deploys the contents of the applications folder. The stage folder (or a folder that you create for the same purpose) is for storing copies of deployment files that are ready for deployment in a production environment (deployments that use the stage or external_stage deployment modes).
94.How do I turn the auto-deployment feature off?
The auto-deployment feature checks the applications folder every three seconds to determine whether there are any new applications or any changes to existing applications and then dynamically deploys these changes.

The auto-deployment feature is enabled for servers that run in development mode. To disable auto-deployment feature, use one of the following methods to place servers in production mode:

In the Administration Console, click the name of the domain in the left pane, then select the Production Mode checkbox in the right pane.
At the command line, include the following argument when starting the domain's Administration Server:
-Dweblogic.ProductionModeEnabled=true Production mode is set for all WebLogic Server instances in a given domain.

95.I downloaded the WebLogic Server installation file, but the installation program will not run. What should I do?
The installation file may have been corrupted during the download. Run a checksum on the installation file and check with technical support for the proper values.
96.Do I need to install WebLogic Server as root on Solaris?
No you don't need to be root, depending on directory permissions.
97.Can I run the Configuration Wizard outside the installer?
Yes. You can start the Configuration Wizard from the Start menu or using a script in the utils directory. See Creating Domains and Servers in Configuring and Managing WebLogic Server.

98.How do I edit the config.xml file?
The persistent configuration for a domain of WebLogic Servers and clusters is stored in an XML configuration file (config.xml). You can modify this file in the following ways:

  • Use the Administration Console. See "Using the Administration Console" in the Administration Console Online Help.
  • If you want to create scripts that automate domain management, use the weblogic.Admin utility. See "weblogic.Admin Command-Line Reference" in the .
  • If you want to create Java-based management applications, use the Java Management Extensions (JMX) Application Programming Interface (API). See the Programming WebLogic Management Services with JMX guide.
  • If you want to edit the config.xml file directly (not recommended), see the BEA WebLogic Server Configuration Reference.

99.What is the free pool?
The free pool is a data structure the EJB container uses to cache anonymous instances of a given bean type. The free pool improves performance by reusing objects and skipping container callbacks when it can.
100.Can I use the PointBase DBMS included with WebLogic Server for development or production?
PointBase Server is an all-Java DBMS product included in the WebLogic Server distribution solely in support of WebLogic Server evaluation, either in the form of custom trial applications or through packaged sample applications provided with WebLogic Server. Non-evaluation development and/or production use of the PointBase Server requires a separate license be obtained by the end user directly from PointBase.
