Project partitioned data sets

This section provides guidance on what data set attributes should be used for the project partitioned data sets. SCLM does not restrict the format of a data set.

Note: Data sets of the same type must be allocated with the same attributes.

Table 1 lists recommended data set attributes for some typical types. For best performance, specify blocksize=0 to use the system-determined block size. Load module data sets should be allocated with a block size of 6144 or greater.
