The Update PDS Allocation screen lets you increase or decrease the number of directory blocks or the primary allocation of a PDS.
------------ CA File Master Plus -- Update PDS Allocation ---------- COMMAND ===> Specify PDS to be Updated Data set name ===> 'TECH1.JCL.CNTL' Allocation Allocated Used New Directory blocks 25 1 _____ Tracks 57 20 ________ PDS is renamed to backup PDS. When Backup PDS DSN is blank, a DSN for the backup will be generated. Backup PDS ===>
When typing an updated number of Directory Blocks or Primary Allocation, a new PDS is allocated according to your specifications and all of the members are copied from the original PDS to this new PDS. If the copy operation is successful, the original PDS is renamed to a Backup PDS DSN and the new PDS is renamed to the DSN of the original PDS.
Tip: You can type a DSN for the Backup PDS, but it is usually more convenient to let the process calculate this DSN for you.
This function only works with a PDS and is not necessary for a PDS/E.
