This new feature extends automatic transaction support to include recoverable transactions without any application changes. This feature permits files to be automatically created with PREIMG or TRNLOG support. Appropriate transactions are automatically started such that, except for the configuration entries, the application itself would not require any changes. An open file would also set the file to PREIMG provided the index was capable.
Applications that don’t currently employ transaction processing can enjoy many of the benefits of transaction processing, such as online backup capabilities with complete data consistency maintained.
