Job Features and Functions
- Restores transaction records to Micro file based on date range
- After backup Micro is restored, replaces lost transactions
- Records restored are based on data range, specified in ES2N parameters
Job 026D is a recovery utility job that restores the contents of Micro File records from transaction historical data for a specified time frame. This is usually needed only when there has been a rare loss of the production Micro File due to a disk head crash, etc. For instance, if the Micro File had to be restored from a backup file that was created several days earlier, and a significant number of on-line transactions had been made subsequent to the backup file date, this job could be run to re-apply the on-line transactions that are stored in the Transaction File. The beginning and ending dates specified in the ES2N screen determine Transaction File records to be used in restoring the Micro File.
Obviously, the transaction records to be reprocessed must still reside in the Transaction Files. If the desired Transaction File records have been deleted from the Transaction Files, this job cannot be used to assist in rebuilding the Micro File. In this event, the deleted transactions would likely have to be re-entered by hand.
This job updates the Micro File directly and on-line. The Micro File does not need to be disabled in CICS before running this job.
A report of Transaction File accounts processed by this job is produced. The report displays the U-I account number, initial transaction date and time, type of transaction (change, add, delete), and user ID for each record processed. A separate notation specifies any unusual condition encountered, such as attempting to add a record that is already on file.
Be cautious about running this job, as it can have unintended consequences.
