There is a job in UAT, in which one step is to copy a flat file to a VSAM file. Approximately 14 million records are copied each day. The run time for the same is approximately 1 hr. 45 min. The VSAM file is delete/define in the job along with VSAMINIT (VSAMINIT is a process where we initialize a VSAM file before using it in read/write mode). As a solution, we decided to remove VSAMINIT step is removed from the job and approximately 50 minutes of UAT batch window is reduced.
