Hi: The average record size is probably one of the nonsense parameters in the CLUSTER definition. It is my understanding that it is used primarily when you define the space requirements in RECORDS versus Cylinders and Tracks. Do you really know the average record size? I am not completely sure if there has been a change in this area but VSAM did not update this figure even after the file is loaded. Therefore, if you set it too low and use RECORDS for the space definition, you could wind up with a lot of extents. I tend to use the most common record size for this figure but YMMV.

Thanks Anthony. For my understanding you say to use the value of 77 for RECORDSIZE(77 4601)) Is the value from the KEYS parm (77 0) which is also applied to the RECORDSIZE of (77 4601)) ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
