Greg, Coding the DSORG is best practice for SDB. Omitting BLKSIZE or coding BLKSIZE=0 is user preference.
Simply removing BLKSIZE or changing to BLKSIZE=0 is common practice, but it is not good practice. This is why SDB was not used for Ron's a Seq allocation examples. This is not good practice: //DD1 DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80 And neither is this //DD1 DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80, // BLKSIZE=0 Ron > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] On > Behalf Of Greg Shirey > Sent: Thursday, 16 February 2006 6:44 AM > To: [email protected] > Subject: Re: DASD allocation guidelines > > Hmm, I get that, and maybe I'm just being slow, but you said: > "...best practice for SDB is not to specify BLKSIZE=0, it is to specify > the > DCB and omit the BLKSIZE, or specify the DCB and code BLKSIZE=0." > > I'm unclear on what you're describing for the 'best practice' contrasting > to > what you said was not the best practice. > > Greg > > > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[EMAIL PROTECTED] > Behalf Of Ron and Jenny Hawkins > Sent: Wednesday, February 15, 2006 3:56 PM > To: [email protected] > Subject: Re: DASD allocation guidelines > > > Greg, > > Coding this > > //DD1 DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80, > // DSORG=PS > > Is the same as > > //DD1 DD SPACE=(TRK,(5,1)),RECFM=VB,LRECL=80, > // DSORG=PS,BLKSIZE=0 > > Or perhaps I should have said coding in both cases. > > Ron > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO > Search the archives at http://bama.ua.edu/archives/ibm-main.html ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
