We currently use the BLSR (Batch Local Shared Resources) SUBSYS for some of our brutally randomly accessed files. Something today made me look at the AMP parameter on the DD JCL statement and I saw that it allows you to specify many of the options that BLSR allows, such as RMODE31, BUFND, BUFNI, etc. So now I am wondering what the difference between the two is, and why one might be preferred over the other. Or are they not as similar as I am thinking?
Specifically, what would be the difference between this (our current usage): //ICMMSTR DD SUBSYS=(BLSR,'DDNAME=ICMMSTR@ MSG=I', // 'RMODE31=ALL BUFND=10 BUFNI=10') //ICMMSTR@ DD DSN=&DSNENV..ICM.ICMMSTR, // DISP=SHR and this? //ICMMSTR DD DSN=&DSNENV..ICM.ICMMSTR, // DISP=SHR, // AMP=('ACCBIAS=DO,RMODE31=ALL,BUFND=10,BUFNI=10') Any tips?
