List -
I have a VSAM Dataset that has grown over the years. When it was set up -
the INDEX space was left to default
I am wondering if it makes sense to override the Track Allocation and put it
in Cylinders.
We are noticing a little bit of an increase in run time during reorg. I was
wondering if this might be due to the data set having 3.4GB now. This file
is EA/EF so it can grow
Over 4500 Cylinders on the Data
And the index is using tracks 2 pri and 11 sec - size is now 2.4 MB
During reorg we offload records to an archive then reload the current data
back in.
This may be something I cannot improve on, just thought I would see if there
are any insights I am missing.
Process:
Offload the data to a temp file
Archive records older than 2 weeks
Del/Def VSAM dataset
Reload current records to VSAM dataset
This runs daily
Thank you
Lizette
