DASD Requirements for a Shared VSAM Database (optional)

The OPAMSVDB member in the SYS1.OPS.CCLXCNTL data set contains the IDCAMS DEFINE commands and the JCL to create and initialize the shared VSAM KSDS. Tailor and run this JCL to create the file. Information needed to determine the DASD requirements for a shared VSAM database, such as setting the key size, the average and maximum record size for the file, and the primary and secondary record allocations, is contained in the comments of the JCL. Note that each record holds a global variable. The volume parameter must be set.
