Serena StarTool IOO (Input Output Optimizer)

StarTool IOO is the separate product Serena intended for tuning of performance of a subsystem of input-output of mainframes. StarTool IOO is the integrated automatic dynamic system of optimization the z/OS component, the high rates of performance which are responsible for functions of input-output for achievement for the modes of batch processing and request processing in real time. StarTool IOO – one of the best products in the class based on algorithms of collecting and data analysis on request processing of OPEN and transactions of input-output to all types of data sets of VSAM or SAM (QSAM, BSAM and EXCP). Modification of JCL is not required that profitable distinguishes IOO from products of competitors.

Optimization of VSAM, dynamic memory management, consecutive optimization, setup of the size of the block and clipboard. IOO is also delivered with the knowledge base on best values of configuration settings of mainframes for achievement of optimal performance measures in different conditions. IOO "corrects" the available control VSM blocks using the "standard" provided IBM interfaces.

Key advantages:

• Automation of tuning of input-output operations for mainframes
• Reduces operating time of the engineer on setup of performance
• Dynamically arranges input-output subsystem configuration settings on the basis of the analysis of the arriving requests
• Reduction of CPU time by 30-50%
• The knowledge base on setup of performance
  • Idle time in use and setup
