Sizes for Parallel Sysplex structures
If you want to use Job Optimizer Pipes in Global mode (SYSPENV=YES is specified in the Job Optimizer Pipes initialization parameters), you must first define two Parallel Sysplex structures—a List structure and a Lock structure.
This section provides instructions about how to determine the size of these structures. Use these sizes to define the Job Optimizer Pipes Parallel Sysplex structures. The following table describes the parameters in a structure definition.
Parameter | Description |
|---|---|
SIZE | Specifies the maximum amount of space to be allocated for the structure in the coupling facility. The number is specified in units of 1 KB (1024 bytes). |
INITSIZE | Specifies the initial amount of space to be allocated for the Parallel Sysplex List structure in the coupling facility. The number is specified in units of 1 KB (1024 bytes). |
ALLOWAUTOALT | (If using Version 2.10 or later of the IBM OS/390 operating system) Enables the XCF mechanism to automatically alter structure sizes, for better management of Coupling Facility structure sizes. To use this facility, define the Coupling Facility structure with the ALLOWAUTOALT=YES parameter. For more information about this parameter, see the IBM publication Setting Up a Sysplex. |
