15 Diagnostic Framework Custom WLST Commands

The Diagnostic Framework aids in capturing relevant and timely diagnostics for critical errors. The diagnostics can be sent to Oracle Support for further analysis. Use the Diagnostic Framework commands to generate incidents, query existing incidents and execute individual diagnostics dumps to gather specific diagnostics data.

For additional information about using the Diagnostic Framework, see "Diagnosing Problems" in the Oracle Fusion Middleware Administrator's Guide.

Note:

To use the Diagnostic Framework custom WLST commands, you must invoke the WLST script from the Oracle Common home. See "Using Custom WLST Commands" in the Oracle Fusion Middleware Administrator's Guide.

Table 15-1 lists the different categories of Diagnostic Framework commands.
