I/O BoosterEnhance your batch window
Improve sequential files
Add buffers dynamically
No JCL or program modifications
Respect buffers already specified
Built to boost sequential I/O’s of batch jobs
The I/O Booster product intercepts each Open issued by z/OS through the applications and modifies the buffers, increasing it according to parameters previously established in the product.
As the main part of the process, the I/O Booster has a dynamic interface in z/OS Open routines which is invoked every time an OPEN is issued for NON VSAM files.
Once the I/O Booster is active, and the table of rules is loaded into memory, the I/O Booster updates buffers parameter for each file that matches with I/O Booster rules applying the most suitable value for buffers.
Through an user-friendly ISPF interface are parameterized which jobs / steps / procsteps / programs / ddnames / dsnames and userids should or should not have their datasets buffered with the suitable buffer limits.
