Running JADE Production Mode Databases

Production mode is designed for use with JADE systems running in production where changes to the database occur only under managed conditions and performance may be improved at the cost of memory usage.

In production mode, internal structures for classes are not released when the class is no longer in use. Subsequent class usages reuse these structures, avoiding the overhead of allocating and opening the class. Classes in the schema remain in use on the node as long as an application running on that node has accessed the schema. For details about enabling or disabling production mode, see "Using the Production Mode Command", in Chapter 1 of the JADE Database Administration Guide. In production mode:

• Continuable exceptions cannot be ignored in the default Unhandled Exception dialog.

  The Ignore button is disabled on the default Unhandled Exception dialog (changing the behavior of the Exception class showDialog method).

• When performing a reorganization, the transition must be initiated in single user mode.

  When you start a production mode, single user, JADE development environment so that you can perform a reorganization, applications, JadeScript methods, and Workspaces should not be used before or after the reorganization, or exceptions may be raised.

  When the reorganization is complete, you can restart the JADE development environment.

• The Jade User Interrupt icon is not displayed.
