Import Transactions task

This task processes the transaction files that have corresponding .smf semaphore files. The transaction files can consist of "raw swipes", "table dump requests", or "reader statuses updates". If "table dump" requests are received, the export task is invoked to create the required records. Transaction records are inserted into the CLOCK_TRAN_PEND_J table and status records update the readers' status fields in the READER table.
