Data CI of 512? Is there a technical reason for this? Strongly suggest raising this to 8K, or 20K. Something that will give you better DASD utilization as well as performance. Once you have increased data ci, define Index CI as 2k or 4k to eliminate dead space in the data ci. Bufsp should be equal to the number of bytes in the data CA + 1 Index CI. Do you really need Freespace? If this file is truly ....temp then I suspect not.
If you do the above you can remove AMP parameter from the jcl. -----Original Message----- From: Joe jeffries [mailto:[EMAIL PROTECTED] Sent: Thursday, September 28, 2006 9:21 AM To: [email protected] Subject: Re: How many?????? - 33 PAVS to one device Here's the VSAM DEF DEFINE CLUSTER- (NAME(xxxx.xxxx.VSAM.xxxTEMP)- RECSZ(0500 0500)- BUFFERSPACE(17920) - KEYS(20 00)- FSPC(00 05)- DATACLAS(200cyls) - SHR(2 3))- DATA- (NAME(xxxx.xxxx.VSAM.xxxTEMP.DATA) - CONTROLINTERVALSIZE(512) - CYLINDERS(1500,200)) - INDEX- (NAME(xxxx.xxxx.VSAM.xxxTEMP.INDEX) - CYLINDERS(5 1)) The JCL gives.....AMP=('BUFND=15,BUFNI=5') Sorry about having to x the name but this company is very hot on confidentiality.
