On-Demand Dynamic Extend

It is preferable to be able to anticipate needed extends and to request them during off-hours instead of during a peak processing time in the MUF. It is also useful if you can override the following three current choices for dynamic extend:

• Whether dynamic allocation is to be requested
• Whether the type is track or cylinder
• The number of the type

The on-demand dynamic extend feature is designed to provide maximum flexibility. It is supported as a console-like command. Being console-like, the command can be issued as follows:

• By using the DBUTLTY COMM function with OPTION=CONSOLE
• By issuing it as a true console command
• By issuing it using any SQL tool that can insert a record (including non-mainframe)

The on-demand dynamic extend feature occurs in the MUF address space. It therefore must be enabled, and a task area must be available. The on-demand dynamic extend can occur with any other normal MUF processing, for example a user application, processing the area being extended.

Note: For more information, see the DYNAMIC-EXTEND console command in the CA Datacom/DB Database and System Administration Guide.
