The WKSPCE option allows you to specify the amount of space for each secondary extent that MFX will obtain for each SORTWK disk data set if no secondary allocation is specified in the JCL SPACE parameter.
Use cccccccc to give an absolute quantity in cylinders. The default is 10 cylinders, and only sorts with primary allocations specified in cylinders are affected.
Use tttttttt to give an absolute quantity in tracks. The default is 200 tracks, and only sorts with primary allocations specified in tracks are affected.
Use bbbbbbbb to give an absolute quantity in blocks. The default is 400 blocks, and only sorts with primary allocations specified in blocks are affected.
When present, the ppp% subparameter is used to override the defaults for cylinders, tracks, and blocks. It sets the percentage (ppp) of the primary allocation that is to be allocated as space for each secondary extent.
The following rules are important when using ppp%:
- The percent sign (%) must be specified. For example, 80% is a valid value for ppp%.
- It is illegal to specify ppp% unless at least one of the other subparameters is omitted. For example, to request cylinder allocations of 15 secondary cylinders, track allocations of 200 tracks, and block allocations of an additional 20% in work space, specify WKSPCE=(15,200,,20%). Note that, even though 200 is the default for tttttttt, it must be specified here because all defaults are overridden when ppp% is present. A percentage of the primary allocation is used instead.
- The ppp% parameter itself has no default value. When ppp% is omitted, any other omitted sub-parameter receives the default value indicated and no percentage is taken.
