ASG-Fast Access

 

for Quicker CA-IDMS Read, Load, and Update

ASG-Fast Access reduces processing time for CA-IDMS database read, load, and update jobs. It performs I/O by acquiring extra buffer storage and loading it by track– or cylinder-increments – satisfying program requests for I/O at higher CPU speeds, and reducing processing time.

ASG-Fast Access is a utility software package that reduces the CPU and run time of batch jobs used to access the CA-IDMS database. It installs easily, and can automatically adapt or be manually controlled to achieve the best performance improvement, using more efficient processing when reading and writing a track or cylinder in one I/O, and an added layer of buffering. It offers proven run-time reduction, even with the latest high-performance DASD. ASG-Fast Access can be installed across your entire local-mode batch job line without making JCL changes, for an instant performance boost and nightly batch window relief. The Database Administrator can use ASG-Fast Access in CA-IDMS Reorgs, reports, unload/reloads, etc. to shorten down time when database maintenance is needed. 

Differentiators

  • Accelerates your local mode jobs, especially database loads, space reports, and IDMS utilities.

  • Transfers data from disk to memory in amounts that are optimized for the behavior of each job and job step.

  • Constantly monitors job performance and automatically adjusts the number of buffers (within user-defined limits), auto-tuning for optimum performance levels.

  • Can be automatically or manually tuned by batch job without JCL changes.

  • Optionally produces performance reports for monitoring and/or fine tuning.

Benefits

  • Fully compatible with CA-IDMS Versions 14.1 and up, while maintaining compatibility with release 14.0 (and earlier).

  • Speeds random jobs dramatically by placing into memory all or large portions of a database.

  • Takes advantage of the increased performance and larger memory addressing of the latest hardware and z/OS operating systems.
