Recommendations

Consider these recommendations:

• Use half-track blocking as much as possible
• Add VSAM buffers through JCL AMP statements for clusters that are not processed using the LSR buffering technique.
• Consider using Batch LSR on the EQQADDS, EQQWSDS, and EQQRDDS data sets for long-term and daily planning batch processing. If you use Batch LSR on those data sets, it is not required that you specify the value 1, 2, or 3 for the SHRPOOL identifier.
• Perform general z/OS tuning: examine swap rates, dispatching priorities, the UIC, and especially demand paging rates. Reduce demand paging if possible, or consider moving the daily planning batch jobs to a processor with more real storage, in the same GRS ring as the controller, if one is available.
