Hi All,

May I know is it compulsory to use OPEN I-O WITH MASS_UPDATE in updating or posting batch program to prevent the File/Record Lock Issue?

 

What is the bad impact if using the MASS_UPDATE?

    No, it is not compulsory to use mass-update. The docs describe this option.

    However, using this option means that the file is at risk from the time the first update is made until the time the file is closed. Should the machine die during this period, the file will almost certainly be corrupt. To mitigate this issue, Vision writes enough information to disk to ensure that the file can be rebuilt using vutil.
