Thanks Robert - you made the explanation easier.
After reading yours, VSAM Demystified looks demystified.
The reason I come to this forum is, to me you guys are better than the books in simplifying the explanations![icon_smile.gif]()
Coming to the question on the calculation
- This calculation helps me to identify files which can cause failures potentially based on how it is growing and how it is used.
We have around 1000+ files (KSDS & ESDS) and since our Mainframe is quite stable, we identified only 50+ files which need the redefinition.
More questions
1. Will LISTCAT produce correct result on a file irrespective of whether that file is used by a Job or CICS at the time of issuing LISTCAT?
2. Records Retrieved for Index Component - A file read on DATA internally uses index to retrieve the record. Would this not update the Records Retrieved for Index Component?
