You can refresh the VSAM file once a day, every week, or every month, however, you prefer. Refreshing is the same as deleting/defining the VSAM file.
Step 1: Delete existing/current VSAM file
IF LASTCC =8 ; SET MAXCC=0
Step 2: Create a new VSAM File
DEFINE VSAM-FILE_NAME (COND=(0,LT,STEP1)
Whenever you try to delete a file that doesn't exist, you get a return code of 8. The command VERIFY can be used in TSO Prompt to verify that the file exists.
