Depends , refresh can be done dialy/weekly/monthy.

Refresh means just DELETE/DEFINE the VSAM file
i.e this done in two steps
STEP1 : deleting the Existing vsam file;
IF LASTCC =8 ; SET MAXCC=0
STEP2 : DEFINE VSAM-FILE(COND=(0,LT,STEP1)
Note: we will get Return-code=8; when the file we are
trying the delete doen't exist.
