The SYS1.DUMP* data sets here are allocated with a block size of 4160
but rarely used.

There are a lot of advantages to using the dynamic allocation for SVC
dump datasets. PARTIAL dumps become a rare occurrence, you can use SMS
features like compression and striping to save space and improve dump
performance, you don't require automation for dump archive and cleanup.

Subject: SYS1.DUMP* dataset allocation
Anybody any views / information on BLKSIZE of SYS1.DUMP datasets.
Record size of 4160 , no probs. We are getting suggestions of 24960 or
29120 . I can't seem to find the IBM manual that tells me what IBM
suggest.
