Storage Performance tools maximize data storage capacity, reduce VSAM run time, improve CICS® and batch performance, and reduce CPU consumption.
- Optimizes the performance, responsiveness, and scalability of existing systems and investments
- Delivers dramatic improvement in responsiveness, while reducing I/O, storage, and CPU usage
- Provides the intelligence needed to boost the performance and utilization of existing systems and resources, while reducing administrative overhead
- Delivers the insights and controls needed to minimize errors, disruption, risk, and waste
VSAM Performance (IAM)
- Reliable, high-performance alternative to a VSAM Key-Sequenced Data Set (KSDS), a KSDS with Alternate Indexes, an Entry-Sequenced Data Set (ESDS) and a Relative Record Data Set (RRDS)
- Outperforms VSAM by reducing the number of I/O operations resulting in reduced CPU time, elapsed time, and response time
- Lowers costs by exploiting 64-bit storage for buffering and indexing resulting in significant CPU time reduction and improved elapsed time


Disk Reorganization (FDRREORG)
- VSAM data set reorganization solution that is fast, flexible, and intelligent
- Reorganizes VSAM KSDS, Alternate Index (AIX) files, IAM and IAM AIX files, and PDS files
- Provides data set reorganization for IAM files while data sets are open for updating in CICS regions
- Significantly faster than VSAM IDCAMs reorganization, providing a 20% to 60% reduction in wall clock, CPU time, and I/O operations (EXCP) compared to VSAM IDCAMs
Disk Management (FASTCPK)
- Ensures storage volumes are operating at maximum performance and efficiency
- Consolidates free space into one or two contiguous areas to ensure data set allocation is placed on the right disks with correct primary and secondary allocations
- Merges extents from Sequential, PDS, PDSE, VSAM, and Extended Format VSAM data sets and releases all or part of the unused space
