Log Stream Definition

The following JCL stream illustrates the definition of a DASD only log stream where:

• Each offload data set is sized at 12800 4-KB blocks
• The staging data set is sized at 25 MB

None of the SMS class names are explicitly specified (for example, the LS_STORCLAS parameter) in the JCL. For this reason, the rules embodied within the installation SMS ACS routines perform the class assignments.
