VELOCI-Raptor | VR is an intelligent, intuitive, performance optimization tool designed to dramatically improve system performance while significantly reducing system overhead by automating tuning activities. VR assists IT departments in meeting increased service level demands and helping manage growing workloads. VR reduces overhead by optimally allocating buffers for VSAM and non-VSAM files to provide the best throughput and response time for I/O requests.
What does VELOCI-Raptor (VR) do?
For VSAM optimizations
VR intelligently selects either the NSR (Non-Shared Resource) or LSR (Local Shared Resources) buffering techniques, and then uses its internal optimization rules and services to make the most efficient and effective use of that buffering technique.
VR supports all current VSAM macro formats, and can intelligently use those macro formats in conjunction with the selected buffering technique to accelerate application processing. When needed, VR can exploit the use of all 256 LSR buffer pools. VR also provides VSCR (Virtual Storage Constraint Relief) by placing VSAM control blocks and buffers above the 16MB line.
For non-VSAM optimizations
VR ensures optimal tuning and buffer allocation by selecting a buffer count that will optimize the use of SAM/E chained scheduling for asynchronous sequential access (QSAM).
Why optimize batch processing performance and reduce system overhead?
By buffering VSAM and non-VSAM files more efficiently, your system can process applications more quickly and with less demand on the CPU. VR allows users to defer CPU upgrades, thereby saving both time and money.
How does VELOCI-Raptor work?
VR contains a proprietary database containing the rules and parameters that deliver the best I/O performance based on the current characteristics of the target data set and the type of access. Users can override these rules by keying in their own parameters, or by excluding a dataset or job name from VR’s optimization process. Most users however, use the default parameters and achieve outstanding results from VR’s I/O optimization. VR monitors the open and close of any data set and optimally buffers VSAM, QSAM, and BSAM files to significantly reduce the time required for batch processing.
