Technical Examples

A method and system for enhancing the availability of VSAM files is provided. According to one exemplary method performed by a batch program, a '1' file is accessible to the online regions during a business day and a '2' file is built with updated information. Online traffic is switched from the '1' file to the '2' file. The '1' file is then locked up to prevent access by other batch programs. The '1' file is then renamed to '3' to free up the '1' dataset name. The '3' file (which was the old '1' file before it was renamed) is opened and online traffic is switched from the '2' file to the '3' file. Next, the '2' file is locked up to similarly prevent access by other batch programs. The '2' file is then renamed to '1'. The '1' file (which is the original '2' file before it was renamed) is opened and online traffic is switched from the '3' file to the '1' file. Likewise, the '3' file is locked up to prevent any further access by other batch programs. Finally, the '3' file is renamed to '2' thereby making this file available for the batch process to build the '2' file with updated information during the next cycle.
