Abstract

OSP-DB DATASPACE PRE-LOAD LESS AGGRESSIVELY
END OF ABSTRACT

Error Description

Please see the problem summary.                                

Problem Summary

When query optimization determines the whole file member (data  
space) should be "preloaded", that work is done in parallel.    
When the file's "media preference" is SSD, that I/O is much    
faster.  Thus, the OS could throttle back the parallel degree a
bit to avoid over running the system.                          

Problem Conclusion

This PTF throttles back the parallel pre-load processing.
