VR | VSAM/SAM FILE I/O TUNER

 What are the primary challenges that VELOCI-Raptor addresses?

The primary challenges faced by data centers are the need to reduce batch processing time, the need and ability to meet service level agreements, the requirement to maximize system performance without extensive programming changes and the ability to determine system-wide impact of application tuning activities. VR addresses these challenges by:

  • Eliminating CPU time that is wasted during I/O operations.
  • Automatically reducing system overhead and batch window constraints.
  • Eliminating manual tuning efforts.
  • Allowing users to defer or eliminate CPU upgrades.
  • Ensuring service level agreements are more easily met.

 

How would I use VELOCI-Raptor?

VR is easily and transparently installed on any z/OS system. Once enabled, batch I/O requests are analyzed with the resulting buffering environment being modified to utilize the best possible accesses to each file. An immediate and dramatic difference in run times will be seen as buffers are allocated more efficiently, EXCPs are reduced, more storage is available for application programs, and file processing is optimized. 

 

What kind of reports can VELOCI-Raptor generate?

Detailed statistics can be produced showing the type of buffering that was applied and the amount of data movement that occurred. Also available is the number and type of program I/O requests for VSAM files. These statistics may also be recorded in SMF records for later analysis.
