10g AS Application Server Control Utility

In this section we'll cover the debugging options within ASC.

Description

Once a J2EE application has been deployed to the 10g AS mid- tier server, the ASC utility provides a wide range of management options to the administrator. Among these management options is the ability to turn on debugging.

Figure D-1 shows you the available JSP debugging options.

Figure D-1: JSP debugging options

In Figure D-1, you can see that it's possible to do the following:

• Turn debug mode on or off.

• Emit debug information.

• Specify if a recompilation will occur when a JSP changes.

• Run a precompile check.

• Validate XML.

• Use a different Java compiler.

Changing options for JSP isn't all that you can do. At the bottom of the OC4J Server Properties page (see Figure D-2), you can specify command-line options that OC4J will use.

Figure D-2: Specify command-line options

In Figure D-2, you can see that it's possible to do the following:

• Specify a different Java executable.

• Provide different OC4J options.

• Specify different Java options such as memory heap size . You can also specify debug switches, as shown at the end of this appendix.

• Add environment variables .

These provide useful capabilities for when debugging applications and for performance tuning.
